WEBVTT - I Was Eaten by a Giant Spider

0:00:03.080 --> 0:00:05.920
<v Speaker 1>Welcome to Stuff to Blow your Mind from how Stop

0:00:05.920 --> 0:00:14.319
<v Speaker 1>works dot com. Hey, welcome to stuff to Blow your Mind.

0:00:14.320 --> 0:00:17.040
<v Speaker 1>My name is Robert Lamb and I am Joe McCormick

0:00:17.079 --> 0:00:21.079
<v Speaker 1>and Robert. You have seen the horror movies of the

0:00:21.160 --> 0:00:24.439
<v Speaker 1>nineteen fifties, I know you've delve deep into I've seen

0:00:24.440 --> 0:00:26.000
<v Speaker 1>a lot of them, and the ones I haven't seen,

0:00:26.040 --> 0:00:28.200
<v Speaker 1>I've I've watched the trailers. I mean, sometimes that's the

0:00:28.240 --> 0:00:30.400
<v Speaker 1>best way to enjoy a film. They put all the

0:00:30.400 --> 0:00:33.159
<v Speaker 1>best stuff in the trailers. But what was big then?

0:00:33.240 --> 0:00:37.080
<v Speaker 1>It was atomic age panic, right, Yeah, giant animals exactly right.

0:00:37.120 --> 0:00:41.640
<v Speaker 1>So there's nuclear testing, there's atomic radiation, and suddenly animals

0:00:41.720 --> 0:00:45.080
<v Speaker 1>become very big. And one of the animals they would

0:00:45.080 --> 0:00:48.199
<v Speaker 1>make very big, you know quite well, was the spider.

0:00:48.400 --> 0:00:50.320
<v Speaker 1>That's right. I mean with all of them, all you

0:00:50.320 --> 0:00:52.479
<v Speaker 1>need is a little camera magic, and you can make

0:00:52.520 --> 0:00:55.560
<v Speaker 1>anything look big. You didn't have to worry about having

0:00:55.600 --> 0:00:58.080
<v Speaker 1>some sort of fancy stop motion creature. You didn't have

0:00:58.120 --> 0:01:01.360
<v Speaker 1>to worry certainly with c g I or costumes. You're

0:01:01.400 --> 0:01:04.000
<v Speaker 1>just an actual spider. Yeah, film a tarantula and then

0:01:04.080 --> 0:01:06.880
<v Speaker 1>put it in the background, you know, superimposed with the

0:01:06.920 --> 0:01:10.880
<v Speaker 1>different sizes. Yeah, But so there's a sequence and pretty

0:01:10.959 --> 0:01:13.160
<v Speaker 1>much all these movies. I probably haven't seen them all,

0:01:13.200 --> 0:01:16.080
<v Speaker 1>but I've seen some of them where the spider lives

0:01:16.080 --> 0:01:18.720
<v Speaker 1>in a cave or something like that, and the people

0:01:19.120 --> 0:01:21.920
<v Speaker 1>are wandering near the cave and then somebody falls into

0:01:22.040 --> 0:01:25.520
<v Speaker 1>its web and the web is a hammock. It's just

0:01:25.560 --> 0:01:28.240
<v Speaker 1>a hann't it. It's a piece of like it's white

0:01:28.319 --> 0:01:31.720
<v Speaker 1>rope netting. Uh. And people get stuck to the hammock

0:01:31.880 --> 0:01:35.280
<v Speaker 1>and then the spiders coming. Sometimes they escape, sometimes it

0:01:35.319 --> 0:01:39.840
<v Speaker 1>eats them. It's generally a bella legostie pretends to wrestle

0:01:39.959 --> 0:01:43.320
<v Speaker 1>a rubber octopus level of awkward because you're like struggling

0:01:43.560 --> 0:01:45.760
<v Speaker 1>the hammock. Just just get up and get out of it.

0:01:45.800 --> 0:01:48.680
<v Speaker 1>You're clearly not stuck, right. But there's a part we

0:01:48.760 --> 0:01:51.440
<v Speaker 1>never see right now. Often the person gets away. If

0:01:51.440 --> 0:01:54.600
<v Speaker 1>the person gets eaten by the giant spider, we just

0:01:54.640 --> 0:01:58.760
<v Speaker 1>sort of see like a ah, and then the spiders approaching.

0:01:58.840 --> 0:02:05.120
<v Speaker 1>The music swells in. That's it. What happens after that cutaway? Well,

0:02:05.200 --> 0:02:08.840
<v Speaker 1>sometimes we find their bones later, sometimes their their their

0:02:08.840 --> 0:02:12.080
<v Speaker 1>cocoon body shows up later. But I can't think of

0:02:12.400 --> 0:02:16.400
<v Speaker 1>a film off hand that had a prolonged spider cut

0:02:16.639 --> 0:02:19.480
<v Speaker 1>death by spider death scene. I guess they really didn't

0:02:19.520 --> 0:02:22.320
<v Speaker 1>go for the intense, gross outgore scenes like that in

0:02:22.360 --> 0:02:26.360
<v Speaker 1>the nineteen fifties. But even if they did, what would

0:02:26.360 --> 0:02:30.079
<v Speaker 1>they be showing what actually happens when a spider eats

0:02:30.120 --> 0:02:33.320
<v Speaker 1>something at that scale? And that's going to be the

0:02:33.360 --> 0:02:37.280
<v Speaker 1>topic of today's conversation. So we're gonna imagine a nineteen

0:02:37.360 --> 0:02:41.200
<v Speaker 1>fifties Roger Corman atomic radiation movie, but we're gonna take

0:02:41.240 --> 0:02:44.519
<v Speaker 1>it to the next level and go beyond that cut away.

0:02:44.760 --> 0:02:48.600
<v Speaker 1>The movie is I was eaten by a giant spider.

0:02:54.360 --> 0:02:56.280
<v Speaker 1>But I guess first I should ask, for real, what's

0:02:56.280 --> 0:02:59.120
<v Speaker 1>your favorite giant spider movie? Oh? I mean, anytime a

0:02:59.160 --> 0:03:01.880
<v Speaker 1>giant spider turns up mir in for a good time.

0:03:02.040 --> 0:03:04.840
<v Speaker 1>I tend to lean more towards the stop motion ones.

0:03:05.919 --> 0:03:09.720
<v Speaker 1>Let's see, The Giant Spider Invasion is a lot of fun.

0:03:09.840 --> 0:03:12.360
<v Speaker 1>Never seen that this one? Who was an MST? Really yeah,

0:03:12.440 --> 0:03:16.400
<v Speaker 1>it was. It's really good. They're really good. It was

0:03:16.440 --> 0:03:20.079
<v Speaker 1>a really great MST episode. They they used actual spiders,

0:03:20.120 --> 0:03:22.919
<v Speaker 1>as I recall, and there's a there's this like really

0:03:22.919 --> 0:03:27.040
<v Speaker 1>gross kind of hillbilly character in it, and giant spiders

0:03:27.440 --> 0:03:30.200
<v Speaker 1>and somebody drives a car into a giant spider. How

0:03:30.720 --> 0:03:34.480
<v Speaker 1>big are the giant spiders? They are like construction equipment

0:03:34.480 --> 0:03:38.880
<v Speaker 1>big like, so they're ridiculous in terms of size. Um.

0:03:39.120 --> 0:03:41.360
<v Speaker 1>You know, another one I remember from Mystery Science Theater

0:03:41.440 --> 0:03:44.880
<v Speaker 1>three thousand is the I think Horrors of Spider Island.

0:03:45.120 --> 0:03:47.400
<v Speaker 1>That's a good one. That one. That one's one that

0:03:47.560 --> 0:03:49.720
<v Speaker 1>was like it was black and white. It's just a

0:03:49.760 --> 0:03:52.240
<v Speaker 1>real sleezy feel to it because it's like a bunch

0:03:52.240 --> 0:03:58.600
<v Speaker 1>of babes and like one very greased up muscleman that

0:03:58.640 --> 0:04:00.640
<v Speaker 1>are trapped in the island. He turned. It's it's like

0:04:00.680 --> 0:04:02.400
<v Speaker 1>a it's like a dude who has a bunch of

0:04:02.480 --> 0:04:05.520
<v Speaker 1>ladies who work on some nightclub act and they crash

0:04:05.640 --> 0:04:08.960
<v Speaker 1>on a spider island. I haven't seen that one, fairly contrived.

0:04:09.080 --> 0:04:11.240
<v Speaker 1>Come on, I haven't seen that one in years, but

0:04:11.280 --> 0:04:14.280
<v Speaker 1>I do remember, like it's a sweaty looking movie, and

0:04:14.280 --> 0:04:16.960
<v Speaker 1>I remember watching it on VHS and a very sweaty

0:04:17.080 --> 0:04:19.600
<v Speaker 1>college dorm. So it's just like I'm just sitting there

0:04:19.640 --> 0:04:23.080
<v Speaker 1>sweating at night, get my night sweats on, and here's

0:04:23.160 --> 0:04:27.679
<v Speaker 1>this just sweaty, weird, oppressive movie. Now, of course, another

0:04:27.720 --> 0:04:29.760
<v Speaker 1>big point that I'm sure a lot of you listening

0:04:29.839 --> 0:04:32.320
<v Speaker 1>right now are screaming. Is she labbed from Lord of

0:04:32.360 --> 0:04:35.520
<v Speaker 1>the Rings. I remember that from the movies. But can

0:04:35.560 --> 0:04:38.559
<v Speaker 1>I can I admit a little secret good? I've never

0:04:38.600 --> 0:04:41.159
<v Speaker 1>actually read the Lord of the Rings books in full.

0:04:41.880 --> 0:04:44.479
<v Speaker 1>I probably like the only nerd around here who would

0:04:44.480 --> 0:04:48.520
<v Speaker 1>admit that and expect to get out alive. Well, they're good?

0:04:48.600 --> 0:04:51.159
<v Speaker 1>Is that a call? I? I can't read them again until,

0:04:51.640 --> 0:04:53.320
<v Speaker 1>you know, maybe I'll read them with my son or something.

0:04:53.360 --> 0:04:55.880
<v Speaker 1>But I kept telling myself, I'll read them again when

0:04:55.880 --> 0:04:58.599
<v Speaker 1>I get the film adaptation is kind of out of

0:04:58.600 --> 0:05:00.240
<v Speaker 1>my head because I don't want to read them again

0:05:00.240 --> 0:05:03.440
<v Speaker 1>and have those visuals and informant, though the visuals were

0:05:03.440 --> 0:05:05.880
<v Speaker 1>often very good. In fact, I would say that the

0:05:06.000 --> 0:05:09.160
<v Speaker 1>giant spider she loved in the first Lord of the

0:05:09.200 --> 0:05:12.440
<v Speaker 1>Ring film, I think the second, the third one. The

0:05:12.440 --> 0:05:14.279
<v Speaker 1>third one I can't remember because I can't remember where

0:05:14.279 --> 0:05:16.520
<v Speaker 1>that where she shows up in the she shows us

0:05:16.600 --> 0:05:19.640
<v Speaker 1>versus the movies in the third movie when the Hobbits

0:05:19.640 --> 0:05:23.080
<v Speaker 1>are here, we can okay, So the Hobbits are in

0:05:23.160 --> 0:05:25.839
<v Speaker 1>more door, the evil land where you know they're towards

0:05:25.839 --> 0:05:28.680
<v Speaker 1>the end of their journey, but a big spider attacks. Okay,

0:05:28.680 --> 0:05:31.440
<v Speaker 1>I guess it was the third movie. It's the movie

0:05:31.520 --> 0:05:34.000
<v Speaker 1>is kind of blurred together for me, but but I

0:05:34.000 --> 0:05:36.960
<v Speaker 1>thought that that scene was fabulous. Like the spider the

0:05:37.120 --> 0:05:41.520
<v Speaker 1>computer animated is just perfect. Yeah, it's like it's basically

0:05:41.520 --> 0:05:44.840
<v Speaker 1>a huge tarantula. We also, though in Lord of the Rings,

0:05:44.880 --> 0:05:48.160
<v Speaker 1>never see exactly what would happen if the spider began

0:05:48.279 --> 0:05:51.320
<v Speaker 1>to feed. We see it bite somebody and cocoon them,

0:05:51.360 --> 0:05:54.159
<v Speaker 1>but it never starts to eat anybody. I have a

0:05:54.279 --> 0:05:58.279
<v Speaker 1>vague memory that the cinematic version of Sheilab also had

0:05:58.680 --> 0:06:01.920
<v Speaker 1>confusing anatomy, but there were there were aspects about it,

0:06:01.960 --> 0:06:05.040
<v Speaker 1>and certainly it's perfectly fine for a monster spider from

0:06:05.040 --> 0:06:09.479
<v Speaker 1>a fantasy uh product to have monstrous features that don't

0:06:09.520 --> 0:06:13.320
<v Speaker 1>line up with with actual real world spider biology. Like

0:06:13.320 --> 0:06:15.960
<v Speaker 1>I think she had a stinger or something. Maybe there

0:06:16.000 --> 0:06:18.840
<v Speaker 1>was some positor acually, I'm not sure what. Yeah, stinger

0:06:18.880 --> 0:06:21.080
<v Speaker 1>where like the silk spin orrets should have been. Yeah,

0:06:21.120 --> 0:06:23.719
<v Speaker 1>I remember she kind of like uh pegged Sam with

0:06:23.760 --> 0:06:27.040
<v Speaker 1>it at and that was kind of strange. But yeah, okay,

0:06:27.080 --> 0:06:30.440
<v Speaker 1>here's another one that I remember but not very well.

0:06:30.600 --> 0:06:33.680
<v Speaker 1>Doesn't doesn't Tim Curry turn into a spider at the

0:06:33.760 --> 0:06:37.240
<v Speaker 1>end of the movie? It? Yes, the uh, the the

0:06:37.360 --> 0:06:42.960
<v Speaker 1>nine TV miniseries. Uh, if you're like me, you probably

0:06:42.960 --> 0:06:47.359
<v Speaker 1>have fun and disturbing memories of this. Uh, this is

0:06:47.360 --> 0:06:50.880
<v Speaker 1>a book I read, probably too early, and then that

0:06:50.920 --> 0:06:53.920
<v Speaker 1>film came out, And of course Tim Curry is perfect

0:06:53.960 --> 0:06:58.120
<v Speaker 1>as Pennywise, the dancey clown and traumatized the whole generation. Yeah,

0:06:58.120 --> 0:07:01.039
<v Speaker 1>as we've said on this show before, any movie that

0:07:01.080 --> 0:07:04.080
<v Speaker 1>Tim Curry's in, he's the best part. Try to think

0:07:04.120 --> 0:07:07.359
<v Speaker 1>of a counter example. You can't. Yeah, he was great

0:07:07.520 --> 0:07:09.760
<v Speaker 1>and and particularly he was great in the first half

0:07:09.760 --> 0:07:12.440
<v Speaker 1>of that mini series, which was mostly the kid's stuff,

0:07:12.840 --> 0:07:15.400
<v Speaker 1>and that was the most effective part of that mini series.

0:07:15.440 --> 0:07:18.280
<v Speaker 1>I think the second part not as strong, and it

0:07:18.320 --> 0:07:23.040
<v Speaker 1>did include a big showdown with with it in a

0:07:23.200 --> 0:07:26.880
<v Speaker 1>giant alien spider form. Actually just looked it up on

0:07:26.920 --> 0:07:30.000
<v Speaker 1>YouTube and watched it before we came in here, and uh,

0:07:30.040 --> 0:07:32.360
<v Speaker 1>it's it's an impressive looking spider. It looks like a

0:07:32.480 --> 0:07:35.400
<v Speaker 1>large animatronic kind of spider. So I don't know if

0:07:35.400 --> 0:07:38.000
<v Speaker 1>it's really terrifying, but it is kind of a neat design. Okay,

0:07:38.320 --> 0:07:40.920
<v Speaker 1>definitely come out of a drain or something. They go

0:07:40.960 --> 0:07:44.320
<v Speaker 1>into a cave and then it has like it it shines,

0:07:44.400 --> 0:07:48.000
<v Speaker 1>it's dead lights through its u Torso I should I

0:07:48.000 --> 0:07:50.080
<v Speaker 1>should do some sort of like a monster the wheat

0:07:50.120 --> 0:07:52.320
<v Speaker 1>breakdown of it on the blog because it's an interesting

0:07:52.320 --> 0:07:57.040
<v Speaker 1>looking credit, but probably not another non scientifically perfect spider. Yeah,

0:07:57.040 --> 0:07:59.520
<v Speaker 1>even less so. And you know it's a it's a creature.

0:07:59.640 --> 0:08:01.960
<v Speaker 1>It's like out from the Toto's Darkness or whatever, so

0:08:02.360 --> 0:08:05.720
<v Speaker 1>you know it's it can get away with being completely alien.

0:08:06.640 --> 0:08:10.120
<v Speaker 1>But there are plenty of other cinematic giant spiders that

0:08:10.160 --> 0:08:13.920
<v Speaker 1>are look more like spiders, behave more like spiders. I

0:08:14.000 --> 0:08:17.160
<v Speaker 1>instantly think of Krul. Of course, there's a fabulous sequence

0:08:17.160 --> 0:08:19.480
<v Speaker 1>in there with a spider like she's like a spider queen,

0:08:19.680 --> 0:08:22.160
<v Speaker 1>and they're giant spiders all along the web and there's

0:08:22.200 --> 0:08:24.400
<v Speaker 1>a lot of the adventuring party has to make their

0:08:24.440 --> 0:08:27.120
<v Speaker 1>way across it gets stuck on a hammock? Is it

0:08:27.200 --> 0:08:29.760
<v Speaker 1>basically a hammock? And Krall I think think that I

0:08:29.800 --> 0:08:32.120
<v Speaker 1>want to remember it being a little more believable than

0:08:32.200 --> 0:08:34.240
<v Speaker 1>that because so many of the effects and Kral are

0:08:34.280 --> 0:08:38.640
<v Speaker 1>pretty top notch, but but I don't specifically remember. I

0:08:38.679 --> 0:08:41.280
<v Speaker 1>think it was a stop motion spider though I see

0:08:41.320 --> 0:08:46.160
<v Speaker 1>you have a note here Robert about an ewalk adventure. Yes, so, um,

0:08:46.480 --> 0:08:49.360
<v Speaker 1>we have a lot of Star Wars fans in the office. Um,

0:08:49.679 --> 0:08:52.560
<v Speaker 1>or at least we have Holly, and Holly is enough

0:08:52.559 --> 0:08:55.440
<v Speaker 1>of a Star Wars fan to like represent multiple people.

0:08:55.480 --> 0:09:00.400
<v Speaker 1>I think she's like she is. She's a true mendous

0:09:00.559 --> 0:09:02.240
<v Speaker 1>Star Wars fan, and I know that she has a

0:09:02.240 --> 0:09:03.960
<v Speaker 1>warm spound her heart for these as well. Some people

0:09:04.000 --> 0:09:05.560
<v Speaker 1>don't care for him. But there were a couple of

0:09:05.600 --> 0:09:08.280
<v Speaker 1>live action Ewok made for TV films that came out.

0:09:08.800 --> 0:09:12.680
<v Speaker 1>The first one was Urs Caravan of Courage and Ewok Adventure,

0:09:13.080 --> 0:09:17.040
<v Speaker 1>and that one features a giant some giant spiders on

0:09:17.080 --> 0:09:19.680
<v Speaker 1>a web. It's been a long time since I've seen

0:09:19.720 --> 0:09:22.200
<v Speaker 1>that one, and I remember it being good but also

0:09:22.280 --> 0:09:25.079
<v Speaker 1>kind of traumatic because there's a lot of like people

0:09:25.120 --> 0:09:28.600
<v Speaker 1>losing their family members in it. Um. But then there's

0:09:28.640 --> 0:09:31.320
<v Speaker 1>also a follow up. I think it's the Battle for Indoor,

0:09:31.760 --> 0:09:33.839
<v Speaker 1>and that one's that I have a lot of fun

0:09:33.880 --> 0:09:35.360
<v Speaker 1>memories of that one. Would watch that one over and

0:09:35.400 --> 0:09:38.840
<v Speaker 1>over again VHS because it has essentially orcs in it.

0:09:39.240 --> 0:09:43.560
<v Speaker 1>It has an evil, uh seductive like raven queen who

0:09:43.640 --> 0:09:46.120
<v Speaker 1>can turn herself into a raven with a magic ring.

0:09:46.679 --> 0:09:50.319
<v Speaker 1>There's a there's a crash spaceship and it's pilot is

0:09:50.360 --> 0:09:53.760
<v Speaker 1>Wilford Brimley, who so it's a it's a true that

0:09:53.840 --> 0:09:56.200
<v Speaker 1>that's tremendous film too, but only the first one has

0:09:56.200 --> 0:09:59.760
<v Speaker 1>a giant spider and finally a more recent giant spider.

0:09:59.800 --> 0:10:02.920
<v Speaker 1>Not two giants, but giant enough to be disturbing. If

0:10:02.920 --> 0:10:05.480
<v Speaker 1>anyone out there is currently watching the latest season of

0:10:05.559 --> 0:10:12.319
<v Speaker 1>Black Mirror on Netflix, the second episode, I believe is

0:10:12.080 --> 0:10:16.560
<v Speaker 1>is wonderful horror Halloween viewing, and does include a scene

0:10:16.559 --> 0:10:20.640
<v Speaker 1>with a monstrous spider, But I say, I'm gonna have

0:10:20.679 --> 0:10:24.200
<v Speaker 1>to check that out this weekend. Anyway, I wanted to

0:10:24.240 --> 0:10:26.560
<v Speaker 1>move on to the next thing, which is that today

0:10:26.600 --> 0:10:29.200
<v Speaker 1>we are going to be talking about people getting eaten

0:10:29.240 --> 0:10:33.200
<v Speaker 1>by giant spiders. But uh, I want to frame this

0:10:33.360 --> 0:10:36.880
<v Speaker 1>with a reminder that it is simply wrong in my

0:10:37.000 --> 0:10:39.840
<v Speaker 1>point of view to contribute to global spider panic, and

0:10:39.880 --> 0:10:42.880
<v Speaker 1>I will not allow us to contribute to global spider panic,

0:10:42.960 --> 0:10:46.520
<v Speaker 1>even if only by accident. Spiders are not your enemy.

0:10:46.640 --> 0:10:49.240
<v Speaker 1>If you're a human and the spider is a normal

0:10:49.280 --> 0:10:52.320
<v Speaker 1>sized spider, that's not you know, at least ten times

0:10:52.360 --> 0:10:55.959
<v Speaker 1>bigger than the biggest spider could ever get. Spiders are

0:10:56.000 --> 0:10:58.520
<v Speaker 1>are not something to worry about. They generally pose no

0:10:58.600 --> 0:11:02.040
<v Speaker 1>threat to humans, with the small exceptions of a few

0:11:02.080 --> 0:11:05.320
<v Speaker 1>species that even those are not something you should really

0:11:05.360 --> 0:11:07.800
<v Speaker 1>worry about. There's no good reason you need to go

0:11:07.840 --> 0:11:11.240
<v Speaker 1>around squashing spiders, and in fact, you would probably find

0:11:11.240 --> 0:11:15.480
<v Speaker 1>a world without spiders utterly intolerable. They make it okay

0:11:15.520 --> 0:11:18.520
<v Speaker 1>for us to live on this planet. Now, now, Joe,

0:11:18.559 --> 0:11:20.679
<v Speaker 1>I know some people are thinking right now and maybe

0:11:20.679 --> 0:11:23.720
<v Speaker 1>even writing the email. They're gonna say, Hey, what about

0:11:23.840 --> 0:11:26.160
<v Speaker 1>the black woodow spiders and the brown reclusives that live

0:11:26.200 --> 0:11:28.600
<v Speaker 1>in my shed? Should I not kill those on site?

0:11:28.640 --> 0:11:31.200
<v Speaker 1>Should I allow those? Why do you need to kill them?

0:11:31.520 --> 0:11:32.880
<v Speaker 1>I don't know. I mean a lot of people would

0:11:32.920 --> 0:11:35.360
<v Speaker 1>argue that is saying, I this is my shed, this

0:11:35.440 --> 0:11:38.120
<v Speaker 1>is where I go to get my tools. I don't

0:11:38.160 --> 0:11:41.880
<v Speaker 1>want to grab a hoe and then have a black

0:11:42.160 --> 0:11:46.280
<v Speaker 1>woo spider stingy. Well, I don't know're not sting me

0:11:46.440 --> 0:11:48.640
<v Speaker 1>rather but bite me? Sting still with his little stick

0:11:50.360 --> 0:11:53.720
<v Speaker 1>to my brain. I mean, I guess I can't argue

0:11:53.720 --> 0:11:56.240
<v Speaker 1>with what you do in your shed, but but I

0:11:56.240 --> 0:11:58.400
<v Speaker 1>I don't. We do not want to push an anti

0:11:58.440 --> 0:12:02.960
<v Speaker 1>spider message here. Spy piers, spiders perform essential services for

0:12:03.040 --> 0:12:05.880
<v Speaker 1>human beings and really all the other creatures on Earth.

0:12:05.960 --> 0:12:09.520
<v Speaker 1>I would say one of the primary things is insectivorous services.

0:12:09.600 --> 0:12:15.120
<v Speaker 1>So spiders are primary predators that prey on insects. Imagine

0:12:15.160 --> 0:12:19.560
<v Speaker 1>a world in which the primary control on insect populations

0:12:19.720 --> 0:12:22.520
<v Speaker 1>is gone. You know, we've just squashed them all because

0:12:22.559 --> 0:12:24.319
<v Speaker 1>we didn't like the way they looked, or we were

0:12:24.360 --> 0:12:27.040
<v Speaker 1>afraid of them, or something like that. I found one

0:12:27.160 --> 0:12:30.640
<v Speaker 1>article that interviewed the arachnologist Norman I. Platinik, who works

0:12:30.679 --> 0:12:33.200
<v Speaker 1>at the American Museum of Natural History in New York,

0:12:33.280 --> 0:12:35.600
<v Speaker 1>which is probably the coolest place I went this year.

0:12:36.080 --> 0:12:40.280
<v Speaker 1>Um and Platinum speculates that if spiders were to disappear

0:12:40.360 --> 0:12:43.920
<v Speaker 1>from the Earth, it's likely that human beings would face famine.

0:12:44.000 --> 0:12:46.840
<v Speaker 1>He says, without spiders, all of our crops would be

0:12:46.880 --> 0:12:51.040
<v Speaker 1>consumed by these pests, the pests that are primarily controlled

0:12:51.080 --> 0:12:54.200
<v Speaker 1>by spider predation. So it's hard to know for sure

0:12:54.240 --> 0:12:57.520
<v Speaker 1>what would happen in these weird hypothetical scenarios with ecology,

0:12:57.559 --> 0:13:00.520
<v Speaker 1>but I think that's a pretty safe bet to uh.

0:13:00.720 --> 0:13:02.199
<v Speaker 1>And you know, when it comes back to come back

0:13:02.200 --> 0:13:05.280
<v Speaker 1>to black widows for instance, sure you don't want to

0:13:05.320 --> 0:13:08.400
<v Speaker 1>be they become bitten by one, but that black widow

0:13:08.480 --> 0:13:11.959
<v Speaker 1>is there because their insects to eat, so she's doing

0:13:12.000 --> 0:13:16.360
<v Speaker 1>a service. And if you're concerned about their being an

0:13:16.440 --> 0:13:19.400
<v Speaker 1>imbalance here with too many black widows around, then I

0:13:19.440 --> 0:13:22.240
<v Speaker 1>think one possible solution would be just don't knock down

0:13:22.240 --> 0:13:26.320
<v Speaker 1>those dirt daver wasp nests because they in turn prey

0:13:26.360 --> 0:13:28.640
<v Speaker 1>on the spiders are that bring them back to their

0:13:28.640 --> 0:13:32.920
<v Speaker 1>nests anyway for their their brood to emerge from and consume.

0:13:33.080 --> 0:13:36.120
<v Speaker 1>So allow the web of life to work itself exactly exactly,

0:13:36.120 --> 0:13:38.679
<v Speaker 1>and the wasp nous of life to work it I

0:13:38.760 --> 0:13:42.160
<v Speaker 1>must add too, as in accordance with the research that

0:13:42.240 --> 0:13:44.559
<v Speaker 1>I that I was working on for this episode, even

0:13:44.720 --> 0:13:48.960
<v Speaker 1>most black widow spider bites today do not result in death. Like,

0:13:49.040 --> 0:13:51.079
<v Speaker 1>you don't want to be bitten by a black widow,

0:13:51.440 --> 0:13:54.040
<v Speaker 1>but if you get if you get a black widow bite,

0:13:54.080 --> 0:13:57.040
<v Speaker 1>seek medical attention, you will probably be all right. I

0:13:57.080 --> 0:13:59.440
<v Speaker 1>think I read that since nineteen seventy it's been like

0:13:59.559 --> 0:14:02.320
<v Speaker 1>one scent or less of people bitten by black widows

0:14:02.360 --> 0:14:04.040
<v Speaker 1>end up dying. And I think I've also read that

0:14:04.160 --> 0:14:07.880
<v Speaker 1>every night the average person consumes twenty seven black widow

0:14:07.880 --> 0:14:10.240
<v Speaker 1>spiders just in the course of sleeping. The crawl right

0:14:10.280 --> 0:14:13.200
<v Speaker 1>in there. That is a true fact. That's where we

0:14:13.240 --> 0:14:16.400
<v Speaker 1>get essential vitamins and minerals. All right, So, what are

0:14:16.400 --> 0:14:20.840
<v Speaker 1>some other reasons that we should keep the old arachnets around? Well,

0:14:20.880 --> 0:14:23.640
<v Speaker 1>beyond the fact that animals deserve to live for their

0:14:23.640 --> 0:14:25.880
<v Speaker 1>own sake, they are useful to us for plenty of

0:14:25.880 --> 0:14:30.080
<v Speaker 1>other reasons. Spiders have a lot of biommetic technological uses

0:14:30.240 --> 0:14:32.760
<v Speaker 1>that people are learning more and more about all the time.

0:14:33.040 --> 0:14:35.960
<v Speaker 1>One of the things would be their silk, for example. Yeah, indeed,

0:14:35.960 --> 0:14:39.080
<v Speaker 1>we we have to have an older episode that they

0:14:39.160 --> 0:14:43.040
<v Speaker 1>just rolls through all the various ways and reasons that

0:14:43.080 --> 0:14:46.840
<v Speaker 1>we're trying to steal the secret of the silk. And really,

0:14:46.880 --> 0:14:50.280
<v Speaker 1>I mean it goes back to ancient mythology to um,

0:14:50.640 --> 0:14:55.280
<v Speaker 1>was it Arachney who lost the bet? A weaving bet

0:14:55.320 --> 0:14:58.560
<v Speaker 1>with the gods or looming? I guess we're using a loom,

0:14:59.080 --> 0:15:01.600
<v Speaker 1>but at any rate, Uh, Yeah, the silk of the

0:15:01.640 --> 0:15:06.800
<v Speaker 1>spider is an amazing material, a true meta material. Um.

0:15:06.920 --> 0:15:10.040
<v Speaker 1>They have special glands that secrete silk proteins dissolved in

0:15:10.080 --> 0:15:12.760
<v Speaker 1>a water based solution, and the spider pushes the liquid

0:15:12.760 --> 0:15:16.480
<v Speaker 1>solution through long ducts. These ducts leaved him lead to

0:15:16.640 --> 0:15:22.280
<v Speaker 1>microscopic spigots on the spiders spinnerets, spigots. Don't you wish

0:15:22.320 --> 0:15:26.000
<v Speaker 1>you had spigots and and uh and generally there are

0:15:26.040 --> 0:15:28.560
<v Speaker 1>two or three spinner at pairs located at the rear

0:15:28.560 --> 0:15:31.480
<v Speaker 1>of the abdomen. Furthermore, each spigot has a valve that

0:15:31.520 --> 0:15:34.720
<v Speaker 1>controls the thickness and speed of the excruted material. So

0:15:34.760 --> 0:15:38.000
<v Speaker 1>the idea here is that when we're talking about the

0:15:38.000 --> 0:15:39.920
<v Speaker 1>silk of a spider, it's not just that they have

0:15:39.920 --> 0:15:42.400
<v Speaker 1>a little spool of thread in there, or that it's

0:15:42.440 --> 0:15:46.160
<v Speaker 1>just you know, a silly string type situation. There is

0:15:46.240 --> 0:15:52.160
<v Speaker 1>a manipulation of these of these proteins and the there's

0:15:52.200 --> 0:15:55.720
<v Speaker 1>a an actual weaving that takes place. They're forming a

0:15:55.800 --> 0:15:59.120
<v Speaker 1>material and they act The exact form of the material

0:15:59.160 --> 0:16:02.880
<v Speaker 1>will vary depending on what they're using the silk for.

0:16:03.240 --> 0:16:05.920
<v Speaker 1>I mean, even with with one spider individual, they may

0:16:06.160 --> 0:16:09.760
<v Speaker 1>may be producing various versions of the product depending on

0:16:09.840 --> 0:16:12.560
<v Speaker 1>what they needed for. So as the biggts pulled silk

0:16:12.600 --> 0:16:16.520
<v Speaker 1>molecules or spidrons out of the duct out of the

0:16:16.640 --> 0:16:19.800
<v Speaker 1>ducts and extrude them into the air, the molecules are

0:16:19.840 --> 0:16:22.360
<v Speaker 1>stretched out and linked together and they form these long strands,

0:16:22.800 --> 0:16:25.560
<v Speaker 1>and the the spinnerets wind these strands together to form the

0:16:25.600 --> 0:16:31.160
<v Speaker 1>sturdy silk fiber okay um. Most spiders have multiple silk

0:16:31.200 --> 0:16:34.800
<v Speaker 1>glands which secrete different types of silk material optimized for

0:16:34.840 --> 0:16:38.480
<v Speaker 1>those different purposes. So by winding different silk varieties than

0:16:38.560 --> 0:16:42.600
<v Speaker 1>together in varying proportions, spiders can form a wide range

0:16:42.640 --> 0:16:46.400
<v Speaker 1>of fiber materials, and they can also vary fiber consistency

0:16:46.440 --> 0:16:49.560
<v Speaker 1>by adjusting the biggests to form smaller or larger strands.

0:16:49.600 --> 0:16:52.720
<v Speaker 1>So they're they're true marvels. I mean, it's not just

0:16:52.800 --> 0:16:55.720
<v Speaker 1>that the material is great, but just their manipulation of

0:16:55.760 --> 0:17:00.200
<v Speaker 1>it and their creation of it like they are. There's

0:17:00.240 --> 0:17:02.880
<v Speaker 1>just a level of of of engineering and production going

0:17:02.920 --> 0:17:04.960
<v Speaker 1>on with with the spider that you know, most people

0:17:05.160 --> 0:17:07.639
<v Speaker 1>take completely for granted. And of course the silk is

0:17:07.760 --> 0:17:11.399
<v Speaker 1>very interesting. As I mentioned a mintigo to engineers for

0:17:11.560 --> 0:17:14.520
<v Speaker 1>like material science purposes to study this to see, you know,

0:17:14.600 --> 0:17:16.760
<v Speaker 1>can we make something like this at a larger scale

0:17:16.760 --> 0:17:20.480
<v Speaker 1>that would be useful in building our structures and technology. Yeah,

0:17:20.480 --> 0:17:23.399
<v Speaker 1>because it's it's like a perfect material. It's it's strong,

0:17:23.720 --> 0:17:27.320
<v Speaker 1>but it's flexible. Um. It's organic in nature, so you

0:17:27.359 --> 0:17:31.040
<v Speaker 1>can use it in various bio medical properties. You can

0:17:31.119 --> 0:17:33.879
<v Speaker 1>use it. There are a lot of potential applications and

0:17:34.680 --> 0:17:40.600
<v Speaker 1>artificial limbs, artificial tissues, artificial tissues, scaffolding. UM. Have also

0:17:40.640 --> 0:17:44.080
<v Speaker 1>read possible for parachuting, like really anywhere you could use

0:17:44.440 --> 0:17:48.639
<v Speaker 1>a really remarkable, strong but flexible material. Uh, spider silk

0:17:49.080 --> 0:17:53.840
<v Speaker 1>has a potential place and spider evolution perfected it and

0:17:54.240 --> 0:17:57.320
<v Speaker 1>we just were biomemetics are just catching up with it,

0:17:57.480 --> 0:17:59.480
<v Speaker 1>you know. I have also read many stories over the

0:17:59.560 --> 0:18:03.240
<v Speaker 1>years about using spider venom for medical purposes. One story

0:18:03.280 --> 0:18:06.639
<v Speaker 1>in particular I remember was about using it to treat

0:18:06.640 --> 0:18:10.880
<v Speaker 1>erectile dysfunction. Is that correct? This is correct? Um? And

0:18:10.880 --> 0:18:13.359
<v Speaker 1>And if anyone's like, oh, spider venom, I mean really,

0:18:13.359 --> 0:18:17.360
<v Speaker 1>when you look at at medicines, the vast spectrum of

0:18:17.520 --> 0:18:20.679
<v Speaker 1>medicines that we we we take from the natural world

0:18:21.119 --> 0:18:24.040
<v Speaker 1>in a large part we're making use of poisons and venoms,

0:18:24.080 --> 0:18:26.280
<v Speaker 1>you know, just figuring out what does this poison or

0:18:26.359 --> 0:18:29.239
<v Speaker 1>venom do, and how can we interact with it at

0:18:29.240 --> 0:18:31.800
<v Speaker 1>the appropriate dosage, of the appropriate level, How can we

0:18:31.840 --> 0:18:35.679
<v Speaker 1>exploit those properties for our benefit. So in this case,

0:18:36.119 --> 0:18:39.280
<v Speaker 1>let's talk to a second about erectile dysfunction. Existing erectile

0:18:39.359 --> 0:18:43.800
<v Speaker 1>dysfunction drugs manipulate valves controlling blood flow into the penis,

0:18:44.440 --> 0:18:46.920
<v Speaker 1>but they don't always work. In fact, they don't work

0:18:47.000 --> 0:18:50.160
<v Speaker 1>on one out of every three men who require any

0:18:50.280 --> 0:18:54.560
<v Speaker 1>D drug. So we send in the spider. Specifically, we

0:18:54.680 --> 0:18:58.399
<v Speaker 1>spend in the Brazilian wandering spider, also known as the

0:18:58.440 --> 0:19:04.880
<v Speaker 1>banana spider. UH. They however, rarely crawl on bananas, which

0:19:04.960 --> 0:19:07.560
<v Speaker 1>you know that will make sense to just a second here.

0:19:07.640 --> 0:19:11.520
<v Speaker 1>So these are five inch or thirteen centimeter arachnids. They

0:19:11.560 --> 0:19:14.680
<v Speaker 1>carry a venom that can cause pain, swelling, increased heart rate,

0:19:14.760 --> 0:19:19.080
<v Speaker 1>and also preappism, which is a condition that affects those

0:19:19.080 --> 0:19:22.080
<v Speaker 1>blood flow valves that already talked about. UH, And this

0:19:22.200 --> 0:19:24.760
<v Speaker 1>results in an erection that can last for more than

0:19:24.800 --> 0:19:28.639
<v Speaker 1>four hours, is usually painful, and may happen without sexual arousal.

0:19:28.880 --> 0:19:32.840
<v Speaker 1>So we're talking about blood potentially coagulating and clotting inside

0:19:32.920 --> 0:19:36.920
<v Speaker 1>of the erection. That's how dire situation is. So obviously

0:19:36.960 --> 0:19:40.240
<v Speaker 1>that's nothing that one wants for oneself, but it's a

0:19:40.240 --> 0:19:43.000
<v Speaker 1>great example. Here's the venom. We see that it's interacting

0:19:43.000 --> 0:19:46.399
<v Speaker 1>with this area. Uh, that is that is vital for

0:19:46.760 --> 0:19:49.520
<v Speaker 1>erectile drug creation. Like, there's a lot of money to

0:19:49.560 --> 0:19:53.160
<v Speaker 1>be made in manipulating those valves, and so a lot

0:19:53.160 --> 0:19:55.920
<v Speaker 1>of research has already gotten into this. The researchers work

0:19:56.000 --> 0:19:58.879
<v Speaker 1>to identify the natural derived chemicals in the venom that

0:19:58.960 --> 0:20:01.480
<v Speaker 1>might be taken advantage up and so far they found

0:20:01.480 --> 0:20:04.960
<v Speaker 1>that p n t X two six is the active

0:20:05.000 --> 0:20:08.159
<v Speaker 1>compound in the wandering spider venom, and it's essentially a

0:20:08.200 --> 0:20:11.639
<v Speaker 1>biological version of viagra. It even appears to have fewer

0:20:11.720 --> 0:20:16.159
<v Speaker 1>side effects than existing E D drugs. Uh. However, to

0:20:16.320 --> 0:20:18.520
<v Speaker 1>conduct a proper trial, you have they have to be

0:20:18.520 --> 0:20:21.239
<v Speaker 1>able to replicate the stuff in large enough quantities. And

0:20:21.320 --> 0:20:24.320
<v Speaker 1>this is a situation we get into with both spider

0:20:24.359 --> 0:20:29.719
<v Speaker 1>venom and with spider silk. Spiders are very difficult to farm. Yeah,

0:20:29.960 --> 0:20:34.120
<v Speaker 1>I remember reading a story years ago about people who

0:20:34.119 --> 0:20:37.840
<v Speaker 1>were weaving a garment out of spider silk. They were

0:20:37.840 --> 0:20:41.600
<v Speaker 1>taking these uh or or weaving spiders at the Madagascar

0:20:41.760 --> 0:20:45.119
<v Speaker 1>or somewhere uh and harvesting their silk in order to

0:20:45.320 --> 0:20:49.200
<v Speaker 1>weave this dress. That that sounds like a crazy project

0:20:49.200 --> 0:20:51.880
<v Speaker 1>to me. I'm not sure if that's well advised, but anyway,

0:20:52.160 --> 0:20:55.320
<v Speaker 1>I think they had to keep capturing and then releasing

0:20:55.400 --> 0:20:58.800
<v Speaker 1>the spiders over and over uh in order to harvest

0:20:58.840 --> 0:21:01.320
<v Speaker 1>their silk, because you can't just keep them, right. Yeah,

0:21:01.400 --> 0:21:04.159
<v Speaker 1>it's not like a silk warrant worm, where where we

0:21:04.160 --> 0:21:08.720
<v Speaker 1>have a silk producing uh insect that we have that

0:21:08.880 --> 0:21:11.960
<v Speaker 1>we have domesticated and warped over time into just a

0:21:12.040 --> 0:21:15.560
<v Speaker 1>you know, pure silk creating organism. But with spiders, most

0:21:15.600 --> 0:21:19.840
<v Speaker 1>of them are territorial carnivores. They're highly aggressive against anything,

0:21:20.480 --> 0:21:24.640
<v Speaker 1>especially their own kind. There are social spiders that exist,

0:21:24.920 --> 0:21:26.960
<v Speaker 1>and these are actually these are actually pretty interesting. I

0:21:27.359 --> 0:21:30.320
<v Speaker 1>hadn't done a lot of reading about them before that.

0:21:30.400 --> 0:21:33.600
<v Speaker 1>They're not quite use social in the manner of bees

0:21:33.720 --> 0:21:36.840
<v Speaker 1>or ants, not team players, right, they don't have casts

0:21:36.920 --> 0:21:39.320
<v Speaker 1>or anything. They're no work or spiders, etcetera. But they

0:21:39.359 --> 0:21:42.040
<v Speaker 1>do cooperate in the rearing of young and the acquisition

0:21:42.080 --> 0:21:45.760
<v Speaker 1>of food. UH. That that being said, most of the

0:21:45.800 --> 0:21:49.080
<v Speaker 1>spiders that people seem to be looking at to potentially

0:21:49.160 --> 0:21:52.679
<v Speaker 1>farm are not social spiders. Uh So anyway, either way

0:21:52.720 --> 0:21:54.560
<v Speaker 1>you look, you shake it. Though, way too much work

0:21:54.600 --> 0:21:57.720
<v Speaker 1>would go into any attempt to raise spiders uh in

0:21:57.920 --> 0:22:01.399
<v Speaker 1>little individual enclosures, and you would still get only a

0:22:01.440 --> 0:22:06.440
<v Speaker 1>limited amount of spider venom or spider or spider silk

0:22:06.480 --> 0:22:09.159
<v Speaker 1>out of the the the effort. So it sounds like

0:22:09.200 --> 0:22:12.000
<v Speaker 1>you'd want to find another way to produce this stuff, right,

0:22:12.119 --> 0:22:16.240
<v Speaker 1>You want genetically modified spider silk or spider venom, And

0:22:16.280 --> 0:22:18.760
<v Speaker 1>in fact, that's what's led to, for instance, the creation

0:22:18.800 --> 0:22:22.119
<v Speaker 1>of the Blessed Goats spider hybrid, which we've covered on

0:22:22.160 --> 0:22:25.040
<v Speaker 1>this show before. I believe where you let's make a

0:22:25.119 --> 0:22:27.600
<v Speaker 1>let's let's tinker with the genetics, let's create a goat

0:22:27.720 --> 0:22:33.879
<v Speaker 1>that essentially milks uh spider silk. That's the wonders of

0:22:33.880 --> 0:22:38.200
<v Speaker 1>our modern age. So that is where researchers have been

0:22:38.200 --> 0:22:42.320
<v Speaker 1>looking with with the spider venom of our banana spider.

0:22:42.880 --> 0:22:47.600
<v Speaker 1>In two thousand fourteen, researchers successfully created a recombin vaculo

0:22:47.720 --> 0:22:50.959
<v Speaker 1>virus with the p n t X two six gene

0:22:51.280 --> 0:22:53.199
<v Speaker 1>and then they use this to infect a culture of

0:22:53.240 --> 0:22:57.919
<v Speaker 1>caterpillar cells, which produced the spider toxin. However, human trials

0:22:57.920 --> 0:23:00.920
<v Speaker 1>are still years away. But this would be the shape

0:23:01.200 --> 0:23:06.000
<v Speaker 1>of futuristic corrections, just just letting in shaped. Yeah, well

0:23:06.000 --> 0:23:09.320
<v Speaker 1>not spider shaped. Uh though, I get one can't help.

0:23:09.320 --> 0:23:10.840
<v Speaker 1>But you know that you have your sort of sci

0:23:10.920 --> 0:23:15.159
<v Speaker 1>fi horror lights go off when you start hearing about

0:23:15.800 --> 0:23:18.240
<v Speaker 1>about erect out as function drugs that are made from

0:23:18.400 --> 0:23:21.399
<v Speaker 1>from spider venom um. But I think it'll be I

0:23:21.440 --> 0:23:24.359
<v Speaker 1>think it'll be fine. Yeah, I've seen also research about

0:23:24.440 --> 0:23:28.440
<v Speaker 1>using spider venom in uh in anti pain medication, essentially

0:23:28.800 --> 0:23:32.000
<v Speaker 1>in analgesix. So there was a study I found in

0:23:32.040 --> 0:23:35.800
<v Speaker 1>the British Journal of Pharmacology which indicated that quote spider

0:23:35.880 --> 0:23:38.399
<v Speaker 1>venoms are a rich natural source of h in A

0:23:38.480 --> 0:23:42.280
<v Speaker 1>V one point seven inhibitors that might be useful leads

0:23:42.320 --> 0:23:46.000
<v Speaker 1>for the development of novel analg six. So the creation

0:23:46.080 --> 0:23:49.679
<v Speaker 1>of new pain killers out of naturally existing proteins and

0:23:49.720 --> 0:23:52.520
<v Speaker 1>stuff that are found in spider venoms. All right, So

0:23:52.680 --> 0:23:56.040
<v Speaker 1>I guess the take home here is that spiders are

0:23:56.880 --> 0:24:00.440
<v Speaker 1>high level produced. There. Their high level is the earns,

0:24:00.480 --> 0:24:04.440
<v Speaker 1>their high level weavers um. They have a mastery here

0:24:04.440 --> 0:24:08.760
<v Speaker 1>in these crafts that humans are severely lack. All we

0:24:08.800 --> 0:24:10.600
<v Speaker 1>can do is try and steal their secrets. And we're

0:24:10.600 --> 0:24:13.600
<v Speaker 1>still trying to steal their secrets. So we certainly should

0:24:13.600 --> 0:24:16.280
<v Speaker 1>not wipe them out because there's still so much to

0:24:16.400 --> 0:24:19.080
<v Speaker 1>learn from them, of course, and that that's only the

0:24:19.119 --> 0:24:22.880
<v Speaker 1>mercenary appeal to your self interest and in gaining new technologies.

0:24:22.920 --> 0:24:25.679
<v Speaker 1>I want to say for the record again, spiders deserve

0:24:25.800 --> 0:24:27.800
<v Speaker 1>to be here on this earth just like you do.

0:24:29.960 --> 0:24:33.080
<v Speaker 1>But okay, so back to the giant spider. I was

0:24:33.119 --> 0:24:40.639
<v Speaker 1>eaten by a giant spider. Well, what does the word

0:24:40.760 --> 0:24:43.600
<v Speaker 1>giant mean? There? I guess we should determine what we

0:24:43.720 --> 0:24:47.000
<v Speaker 1>have in mind. Now. We could start by looking at

0:24:47.080 --> 0:24:49.480
<v Speaker 1>what are the biggest spiders occurring in nature? I know

0:24:49.560 --> 0:24:51.800
<v Speaker 1>some of you at home are already trembling and hearing

0:24:51.840 --> 0:24:54.480
<v Speaker 1>about this news, but uh, there are a couple of

0:24:54.480 --> 0:24:57.359
<v Speaker 1>ways you could measure this right. One way would be

0:24:57.440 --> 0:25:00.959
<v Speaker 1>by mass. What is the heaviest spider ocurring in nature?

0:25:01.240 --> 0:25:04.120
<v Speaker 1>And I think the answer on that is is pretty solid.

0:25:04.440 --> 0:25:07.199
<v Speaker 1>There there is a pretty much universal agreement that the

0:25:07.240 --> 0:25:11.280
<v Speaker 1>answer is the theraphos of Blondie, commonly known as the

0:25:11.320 --> 0:25:14.399
<v Speaker 1>goliath bird eater. That they might be a bit of

0:25:14.440 --> 0:25:17.680
<v Speaker 1>a misnomer because it doesn't seem like they primarily prey

0:25:17.720 --> 0:25:19.919
<v Speaker 1>on birds. I think this comes from some you know,

0:25:20.040 --> 0:25:24.800
<v Speaker 1>nineteenth century illustrations and stuff like that. But uh, like

0:25:24.840 --> 0:25:27.439
<v Speaker 1>I said, there's no evidence that they regularly eat birds,

0:25:27.520 --> 0:25:30.520
<v Speaker 1>but they might on occasion. The spider can weigh about

0:25:30.720 --> 0:25:36.199
<v Speaker 1>six ounces or a hundred and seventy grams. That's heavy.

0:25:36.240 --> 0:25:39.320
<v Speaker 1>That is the weight of more than three standard sized

0:25:39.359 --> 0:25:44.680
<v Speaker 1>Snickers bars or exactly five fun sized Snickers bars. Hold

0:25:44.800 --> 0:25:48.639
<v Speaker 1>five fun sized Snickers bars in your hand. That's how

0:25:48.720 --> 0:25:52.520
<v Speaker 1>much the spider can weigh. I'm glad we're not eating

0:25:52.520 --> 0:25:56.280
<v Speaker 1>those in our sleep. I've heard I've heard stories that

0:25:56.359 --> 0:25:59.440
<v Speaker 1>you can hear these things walking. They'll walk you their

0:25:59.520 --> 0:26:02.959
<v Speaker 1>footfall balls makes sounds. Uh. Now, of course, they mostly

0:26:02.960 --> 0:26:05.879
<v Speaker 1>prey on other arthropods, but they have been known to

0:26:06.000 --> 0:26:10.359
<v Speaker 1>eat small vertebrate animals every now and then. But there's

0:26:10.400 --> 0:26:13.560
<v Speaker 1>another way you could measure the largest spider, and that

0:26:13.600 --> 0:26:16.240
<v Speaker 1>would be by leg span. Right, what's the biggest what's

0:26:16.280 --> 0:26:20.440
<v Speaker 1>the biggest spider in circumference sort of looking down from above, Well,

0:26:20.480 --> 0:26:23.679
<v Speaker 1>it appears to be the giant huntsman spider with legspan

0:26:23.720 --> 0:26:27.399
<v Speaker 1>of up to twelve inches or thirty centimeters, often described

0:26:27.520 --> 0:26:30.240
<v Speaker 1>as being quote the size of a dinner plate that

0:26:30.240 --> 0:26:32.240
<v Speaker 1>shows up a lot. Yeah, because you know, that's a

0:26:32.240 --> 0:26:34.399
<v Speaker 1>wonderful image, the idea of setting down and here's a

0:26:34.440 --> 0:26:36.919
<v Speaker 1>living spider just spread out across your tinner plate. Well

0:26:36.960 --> 0:26:39.520
<v Speaker 1>it also, yeah, it suggests that it's literally on the

0:26:39.560 --> 0:26:42.679
<v Speaker 1>plate in your home. It's replaced your food somehow, or

0:26:43.040 --> 0:26:45.320
<v Speaker 1>the chef has gone mad and decided it is live

0:26:45.359 --> 0:26:49.960
<v Speaker 1>spiders for tenner um. Now, whe where do you find it?

0:26:50.040 --> 0:26:53.879
<v Speaker 1>You find this particular specimen and warm climates around the world, Asia, Australia,

0:26:53.960 --> 0:26:57.879
<v Speaker 1>South America, Africa. They're pretty fast even with their size.

0:26:58.119 --> 0:27:00.480
<v Speaker 1>They live under a loose bark on trip our bark

0:27:00.520 --> 0:27:05.400
<v Speaker 1>of trees and rocks in crevices under foliage. And they're

0:27:05.400 --> 0:27:08.080
<v Speaker 1>actually a rather social spider um, to go back to

0:27:08.080 --> 0:27:10.880
<v Speaker 1>what I mentioned earlier, and dozens of them will sometimes

0:27:10.880 --> 0:27:14.159
<v Speaker 1>sit together on dead trees or stumps, as opposed to

0:27:14.320 --> 0:27:18.439
<v Speaker 1>the sort of typical predatory, loner vibe of a spider

0:27:18.440 --> 0:27:20.200
<v Speaker 1>where it's like, if I see anybody that even looks

0:27:20.240 --> 0:27:23.160
<v Speaker 1>like me, I'm gonna eat them, even if theyre might mate. Well,

0:27:23.200 --> 0:27:27.440
<v Speaker 1>spiders just know not to pass up a good meal. Yeah, okay,

0:27:27.840 --> 0:27:30.280
<v Speaker 1>So so that's about as big as things get in nature.

0:27:30.320 --> 0:27:32.840
<v Speaker 1>And even those are pretty rare exceptions. These are the

0:27:32.840 --> 0:27:36.840
<v Speaker 1>biggest of the biggest. Obviously, that's not going to do it, right,

0:27:37.119 --> 0:27:39.760
<v Speaker 1>These spiders don't really represent a threat to humans even

0:27:39.760 --> 0:27:42.879
<v Speaker 1>though they're the biggest. So how big should our model

0:27:43.040 --> 0:27:47.959
<v Speaker 1>spider be to match the Roger Corman movie proportions? Well,

0:27:48.119 --> 0:27:51.200
<v Speaker 1>then this we get back to some some previous discussions

0:27:51.240 --> 0:27:55.480
<v Speaker 1>we've had about the morphological limits of giant creatures because

0:27:55.560 --> 0:27:58.119
<v Speaker 1>you end up going up against two things, Right, what

0:27:58.600 --> 0:28:02.960
<v Speaker 1>is technically pop stable from like a mad science this,

0:28:03.400 --> 0:28:08.399
<v Speaker 1>you know, raising giant spiders in his basement, versus like,

0:28:08.480 --> 0:28:12.399
<v Speaker 1>what is the largest thing that is sustainable? That the

0:28:12.480 --> 0:28:15.840
<v Speaker 1>largest thing that is effective in the in the battle

0:28:15.880 --> 0:28:18.960
<v Speaker 1>for survival, because you know, it needs to work. It's

0:28:19.000 --> 0:28:21.240
<v Speaker 1>like a business, right, if it's it needs to it

0:28:21.240 --> 0:28:24.520
<v Speaker 1>needs to be an effect, have an effective economic flow

0:28:24.600 --> 0:28:27.960
<v Speaker 1>to it, otherwise it's not going to survive. And you know,

0:28:28.000 --> 0:28:30.240
<v Speaker 1>one way to look at it this we always we

0:28:30.240 --> 0:28:32.439
<v Speaker 1>always go in this direction. When he's saying, all right,

0:28:32.440 --> 0:28:34.440
<v Speaker 1>how called large, told this animal be well, how large

0:28:34.440 --> 0:28:36.679
<v Speaker 1>are they now? We've already answered that how large have

0:28:36.720 --> 0:28:39.400
<v Speaker 1>they been in the past. There was a time where

0:28:39.400 --> 0:28:42.440
<v Speaker 1>we thought that the largest spider to ever live was

0:28:42.480 --> 0:28:47.440
<v Speaker 1>a prehistoric um Um mega acne with a body length

0:28:47.480 --> 0:28:50.200
<v Speaker 1>of three nine millimeters or a little over a foot.

0:28:50.840 --> 0:28:54.200
<v Speaker 1>But paleontologist eventually figured out that this was a sea scorpion,

0:28:55.240 --> 0:28:58.760
<v Speaker 1>not a spider. And if you the actual fossil spiders

0:28:58.760 --> 0:29:02.200
<v Speaker 1>that we have are pretty disappointing. They're pretty small. So

0:29:02.680 --> 0:29:05.360
<v Speaker 1>we kind of get into the you know, whale territory

0:29:05.400 --> 0:29:07.960
<v Speaker 1>here where we say, well, actually the largest specimens that

0:29:08.000 --> 0:29:12.400
<v Speaker 1>we know of are what we have today. Yeah, I

0:29:12.400 --> 0:29:14.800
<v Speaker 1>I mean we've talked about this before. We talked about

0:29:14.800 --> 0:29:16.760
<v Speaker 1>this in our Science of Human Height episode. We had

0:29:16.760 --> 0:29:20.440
<v Speaker 1>a brief digression on on how large insects and spiders

0:29:20.440 --> 0:29:22.080
<v Speaker 1>and stuff like that can get. There seemed to be

0:29:22.120 --> 0:29:26.560
<v Speaker 1>a lot of limits on on the size of these creatures,

0:29:26.600 --> 0:29:30.320
<v Speaker 1>on arthropods with exoskeletons, that their their bodies are just

0:29:30.440 --> 0:29:33.880
<v Speaker 1>not designed to keep getting much bigger like nobodies are

0:29:33.920 --> 0:29:39.000
<v Speaker 1>really and it comes that we often talk about King Kong,

0:29:39.160 --> 0:29:42.360
<v Speaker 1>right like King Kong the Guerrilla as just a giant gorilla,

0:29:42.560 --> 0:29:45.360
<v Speaker 1>his legs would snap because those of a die of

0:29:45.360 --> 0:29:48.240
<v Speaker 1>heat exhaust. Yet, yeah, like that form is not is

0:29:48.280 --> 0:29:52.720
<v Speaker 1>not designed or you know, or did not evolve to

0:29:52.720 --> 0:29:55.800
<v Speaker 1>to to work at greater scales. And the same thing

0:29:55.840 --> 0:29:58.680
<v Speaker 1>is true of insects. Like in an insect level, having

0:29:58.680 --> 0:30:03.320
<v Speaker 1>an exoskeleton is fabulous because you gives you protection. It's

0:30:03.400 --> 0:30:06.840
<v Speaker 1>a lightweight um and then you tend to be rather

0:30:06.880 --> 0:30:09.800
<v Speaker 1>strong creatures too. But but they're working at a different

0:30:09.840 --> 0:30:12.120
<v Speaker 1>scale and when you start start scaling that up, you

0:30:12.200 --> 0:30:14.800
<v Speaker 1>run into problems of Okay, is the instance, a giant

0:30:14.800 --> 0:30:17.240
<v Speaker 1>spider the size of a dump truck or something probably

0:30:17.280 --> 0:30:19.719
<v Speaker 1>wouldn't be able to move. She shilab would probably not

0:30:19.760 --> 0:30:23.960
<v Speaker 1>be able to move if you just just immediately like magically, Honey,

0:30:24.000 --> 0:30:26.880
<v Speaker 1>I shrunk the kids scaled one up to a giant size.

0:30:27.960 --> 0:30:29.920
<v Speaker 1>And then on top of that, all right, you're gonna say,

0:30:29.960 --> 0:30:32.760
<v Speaker 1>well what if it just grew over time, Well, you're

0:30:32.760 --> 0:30:36.560
<v Speaker 1>gonna you have to remember that exoskeletons don't grow. Exoskeletons

0:30:36.600 --> 0:30:39.280
<v Speaker 1>have to be shed. You have to multiple Yeah, so

0:30:39.320 --> 0:30:42.440
<v Speaker 1>it's like soft shell crabs, et cetera. The thing is,

0:30:42.480 --> 0:30:47.240
<v Speaker 1>if you have a sufficiently large invertebrate. Then okay, it

0:30:47.320 --> 0:30:51.120
<v Speaker 1>has this this this giant exoskeleton, and it's hard and

0:30:51.160 --> 0:30:53.360
<v Speaker 1>it's rough, but somehow it's able to live with this thing.

0:30:53.440 --> 0:30:57.080
<v Speaker 1>Maybe maybe it's an immobile giant spider and like villagers

0:30:57.120 --> 0:31:00.400
<v Speaker 1>worship it and bring it, you know, virgins, a drain

0:31:00.520 --> 0:31:03.080
<v Speaker 1>or something. Okay, that's great, But then what happens when

0:31:03.160 --> 0:31:07.040
<v Speaker 1>that giant god spider has to mold. Well, then conceivably

0:31:07.160 --> 0:31:09.680
<v Speaker 1>it might have mold out of its exo skeleton and

0:31:09.720 --> 0:31:12.520
<v Speaker 1>then its body would just collapse and fall apart because

0:31:12.520 --> 0:31:14.680
<v Speaker 1>it didn't have They no longer had an exo skeleton

0:31:14.760 --> 0:31:17.760
<v Speaker 1>supported it's mass. It's just too excessive. Yeah, I mean,

0:31:18.000 --> 0:31:22.400
<v Speaker 1>it's like trying to imagine, um, I don't know. Uh,

0:31:22.480 --> 0:31:24.440
<v Speaker 1>I'm coming up with a horrible exain. Here's here's what

0:31:24.960 --> 0:31:27.920
<v Speaker 1>I tried to think of, like a you know, uh,

0:31:27.960 --> 0:31:32.440
<v Speaker 1>twenty ft wide pumpkin or cantalope or something. It's just

0:31:32.760 --> 0:31:35.400
<v Speaker 1>this is not a sustainable size. I always come back

0:31:35.400 --> 0:31:38.600
<v Speaker 1>to economics. It's like thinking of, all right, what would

0:31:38.600 --> 0:31:40.520
<v Speaker 1>it be I have a great lemonade stand? What have

0:31:40.640 --> 0:31:43.760
<v Speaker 1>I had a lemonade stand that could feed the entire country.

0:31:44.240 --> 0:31:46.280
<v Speaker 1>What if I had a McDonald's restaurant that could that

0:31:46.360 --> 0:31:49.720
<v Speaker 1>could actually feed an entire continent, or in feed they'll

0:31:49.720 --> 0:31:52.719
<v Speaker 1>feed the world. Those are just ridiculous ideas because the

0:31:52.760 --> 0:31:55.280
<v Speaker 1>form can't get people in the door. Yeah, it just

0:31:55.360 --> 0:31:58.880
<v Speaker 1>does not does not work. You're you're talking, You're talking nonsense.

0:31:59.000 --> 0:32:02.640
<v Speaker 1>And it's a more thing like a lemonade stand that feeds,

0:32:02.720 --> 0:32:05.640
<v Speaker 1>that gives lemonade to an entire country, is like a

0:32:05.760 --> 0:32:09.080
<v Speaker 1>spider the size of a building. Right, Okay, so we've

0:32:09.160 --> 0:32:13.800
<v Speaker 1>established why in an environment with our atmospheric pressure and

0:32:13.840 --> 0:32:16.120
<v Speaker 1>Earth gravity and all that kind of stuff, you would

0:32:16.240 --> 0:32:18.840
<v Speaker 1>never see a giant spider. It just wouldn't happen. Now,

0:32:18.840 --> 0:32:22.360
<v Speaker 1>in a weightless environment, genetically modified the giant spiders, I

0:32:22.360 --> 0:32:25.560
<v Speaker 1>think there's a lot of potentially Okay, maybe that's not bad.

0:32:25.960 --> 0:32:30.320
<v Speaker 1>But but let's just roll with it. Okay, we're we're

0:32:30.320 --> 0:32:34.760
<v Speaker 1>going to Roger Corman Land. Just pretend we can ignore

0:32:34.800 --> 0:32:37.760
<v Speaker 1>all that stuff and say we do have a spider.

0:32:38.200 --> 0:32:40.120
<v Speaker 1>I don't know the size of a van or how

0:32:40.160 --> 0:32:42.080
<v Speaker 1>big would a spider have to be to prey on

0:32:42.120 --> 0:32:45.440
<v Speaker 1>a human? Uh, depending on you know, it's it's predatory

0:32:45.480 --> 0:32:48.360
<v Speaker 1>strengths on its venom and stuff like that. It probably

0:32:48.400 --> 0:32:51.520
<v Speaker 1>wouldn't even have to be the size of a van, right, Yeah,

0:32:51.680 --> 0:32:53.960
<v Speaker 1>I was thinking about this and it and also I

0:32:54.040 --> 0:32:57.680
<v Speaker 1>kept running through my mind me and my son watching

0:32:58.160 --> 0:33:01.360
<v Speaker 1>a blackwood a spider on a vacation Arizona, watch it

0:33:01.600 --> 0:33:04.480
<v Speaker 1>try and catch a grasshopper in its web, and thinking

0:33:04.520 --> 0:33:09.600
<v Speaker 1>about those the size comparisons there. I think a large spider,

0:33:09.720 --> 0:33:12.040
<v Speaker 1>like a hunting spider the size of a dog would

0:33:12.080 --> 0:33:16.479
<v Speaker 1>be pretty pretty impressive, but not maybe not so large

0:33:16.520 --> 0:33:18.360
<v Speaker 1>that you would really run into a lot of just

0:33:19.280 --> 0:33:24.600
<v Speaker 1>real severe morphological limits. Okay, kind of like the dog

0:33:24.640 --> 0:33:27.920
<v Speaker 1>costumes you see where the round Halloween where the dog

0:33:28.000 --> 0:33:31.160
<v Speaker 1>is wearing a spider costume. Maybe not a puppy size spider,

0:33:31.240 --> 0:33:35.360
<v Speaker 1>but like a moderate size, too large, dog size spider. Yeah,

0:33:35.400 --> 0:33:37.480
<v Speaker 1>I would think so, you know, and if they're especially

0:33:37.600 --> 0:33:41.120
<v Speaker 1>that creature is hunting the humans with stealth as opposed

0:33:41.120 --> 0:33:44.160
<v Speaker 1>to you know, magic web. But then that's the other thing.

0:33:44.200 --> 0:33:46.800
<v Speaker 1>If scaling up the scaling up the web is an

0:33:46.920 --> 0:33:50.920
<v Speaker 1>entirely different kettle of fish. But but yeah, I think

0:33:50.960 --> 0:33:53.120
<v Speaker 1>a dog sized spider would be able to do it. Okay,

0:33:53.160 --> 0:33:56.000
<v Speaker 1>so that's our lower limit. Let's say, on the other hand,

0:33:56.080 --> 0:33:58.840
<v Speaker 1>we can keep in mind the possibility of of a

0:33:59.160 --> 0:34:02.520
<v Speaker 1>you know, moving ock sized spider or a van sized

0:34:02.560 --> 0:34:06.520
<v Speaker 1>spider that we'll we'll just have those floating in our mind. Okay,

0:34:06.640 --> 0:34:08.960
<v Speaker 1>we won't ask a lot of questions of them, but

0:34:09.120 --> 0:34:11.480
<v Speaker 1>we'll just have them there. All right. Well, let's take

0:34:11.520 --> 0:34:13.200
<v Speaker 1>a quick break and when we come back we will

0:34:13.239 --> 0:34:23.080
<v Speaker 1>discuss how they get you. All right, we're back now, Robert.

0:34:23.120 --> 0:34:26.360
<v Speaker 1>We have to talk about how these spiders catch you.

0:34:26.680 --> 0:34:29.960
<v Speaker 1>Oh yeah, well, there there are so many different species

0:34:30.000 --> 0:34:34.160
<v Speaker 1>of spiders. There's so many different hunting strategies that are

0:34:34.239 --> 0:34:37.840
<v Speaker 1>utilized by spiders. The most familiar is going to be

0:34:37.840 --> 0:34:40.440
<v Speaker 1>the web. But even with the web, there are multiple types,

0:34:40.480 --> 0:34:42.680
<v Speaker 1>so you have just to roll through them real quick.

0:34:42.719 --> 0:34:45.799
<v Speaker 1>You have orb webs, the most common typical spider web.

0:34:46.120 --> 0:34:49.960
<v Speaker 1>You have triangular webs as well. You have funnel spiders

0:34:49.960 --> 0:34:52.160
<v Speaker 1>and then make sheets of silk and then wrap them

0:34:52.200 --> 0:34:55.280
<v Speaker 1>up in to make these funnel shapes. So the funnels

0:34:55.320 --> 0:34:57.399
<v Speaker 1>have one big opening to catch prey, and they also

0:34:57.480 --> 0:34:59.560
<v Speaker 1>have one small opening in the back in case the

0:34:59.560 --> 0:35:02.719
<v Speaker 1>spider and needs to escape, so it's not sticky, but

0:35:02.760 --> 0:35:05.239
<v Speaker 1>the spider can easily move through them. This is its

0:35:05.239 --> 0:35:08.920
<v Speaker 1>home turf, this is its kill room. Okay, so I

0:35:09.000 --> 0:35:11.239
<v Speaker 1>like that idea, Like somebody just wanders into one of

0:35:11.239 --> 0:35:13.200
<v Speaker 1>these and they're like, what the heck is this giant cone?

0:35:13.800 --> 0:35:15.880
<v Speaker 1>I don't know. No, oh goodness, there's a hunting spider

0:35:16.000 --> 0:35:18.440
<v Speaker 1>on the ceiling. And then they got it. Yeah. The

0:35:18.800 --> 0:35:21.840
<v Speaker 1>most common web traps we think of are these flat

0:35:21.840 --> 0:35:24.600
<v Speaker 1>ones that orb webs. But another one is the three

0:35:24.600 --> 0:35:29.920
<v Speaker 1>dimensional traps, right, yeah, yeah, they're take for instance, cobweb spiders,

0:35:29.960 --> 0:35:33.280
<v Speaker 1>so they make small, just random messes of silk string

0:35:33.480 --> 0:35:35.560
<v Speaker 1>that are attached to their surroundings by a long string.

0:35:36.400 --> 0:35:39.719
<v Speaker 1>There are mesh web spiders that make webs that are

0:35:39.760 --> 0:35:42.000
<v Speaker 1>similar to cobweb spiders that they have a little more structure,

0:35:42.239 --> 0:35:44.520
<v Speaker 1>and they're just really found in small, messy webs at

0:35:44.520 --> 0:35:48.000
<v Speaker 1>the tips of vegetation, especially in grassy fields. They can

0:35:48.000 --> 0:35:50.600
<v Speaker 1>also be found under stones and dead leaves. In the

0:35:50.680 --> 0:35:52.960
<v Speaker 1>human scenario, maybe they would show up I don't know,

0:35:53.000 --> 0:35:56.759
<v Speaker 1>in the restrooms of strip clubs, or the or the

0:35:56.760 --> 0:35:59.880
<v Speaker 1>restrooms of of gas stations. I'm thinking just the restroom

0:36:00.040 --> 0:36:02.160
<v Speaker 1>in general. A dirty restroom is a great place to

0:36:02.200 --> 0:36:05.320
<v Speaker 1>find a giant broom stall what is the perfect place

0:36:05.400 --> 0:36:09.040
<v Speaker 1>to get you? Yeah? Um, I love that as the

0:36:09.080 --> 0:36:14.279
<v Speaker 1>tagline for the resulting movie. Here sheet web spiders. They

0:36:14.280 --> 0:36:16.840
<v Speaker 1>make many kinds of webs that are formed out of

0:36:16.840 --> 0:36:20.240
<v Speaker 1>sheets of silk, and the sheets are widely wildly jumbled

0:36:20.280 --> 0:36:23.279
<v Speaker 1>together and they don't have many large gaps. There's also

0:36:23.320 --> 0:36:27.320
<v Speaker 1>an interesting sheet web spider type bowl and doily spiders.

0:36:27.440 --> 0:36:30.600
<v Speaker 1>They make really interesting structures, essentially an inverted dome shaped

0:36:30.640 --> 0:36:34.600
<v Speaker 1>web or bowl suspended over a horizontal sheet web or

0:36:34.920 --> 0:36:38.000
<v Speaker 1>doily spiders hang on the underside of the dome and

0:36:38.000 --> 0:36:39.840
<v Speaker 1>they attack the prey. So we're talking about with some

0:36:40.040 --> 0:36:43.879
<v Speaker 1>rather impressive structures. Now here's what I'm wondering if we

0:36:44.040 --> 0:36:47.280
<v Speaker 1>scaled that up, and again, with all of the reasons

0:36:47.280 --> 0:36:49.600
<v Speaker 1>that would probably never happen in nature, But if we

0:36:49.680 --> 0:36:52.720
<v Speaker 1>just imagine scaling it up, would we would we actually

0:36:52.760 --> 0:36:56.320
<v Speaker 1>stumble into webs? I mean, are the success of webs

0:36:56.400 --> 0:37:02.239
<v Speaker 1>sort of depending on the lack of sensation of insects

0:37:02.320 --> 0:37:04.040
<v Speaker 1>or something? Do you do you kind of have to

0:37:04.040 --> 0:37:07.400
<v Speaker 1>be a little bit dumber than the standard primate in

0:37:07.520 --> 0:37:10.879
<v Speaker 1>order to end up in a spiderweb. Well, I think

0:37:10.920 --> 0:37:14.120
<v Speaker 1>it's interesting to think in terms of the funnel spiders

0:37:14.600 --> 0:37:17.040
<v Speaker 1>that already mentioned in that part of this trick is

0:37:17.080 --> 0:37:21.680
<v Speaker 1>creating an alien environment that the spider has maximum control over.

0:37:22.080 --> 0:37:25.120
<v Speaker 1>So it's how you know, you might be dumb to

0:37:25.160 --> 0:37:27.319
<v Speaker 1>wander in there, but you're not dumb to not know

0:37:27.400 --> 0:37:30.320
<v Speaker 1>your way around this alien Environment's like walking into a

0:37:30.719 --> 0:37:34.160
<v Speaker 1>zenomorph five right, or into you know, a derelict alien

0:37:34.200 --> 0:37:36.520
<v Speaker 1>spaceship and not knowing which way we're to walk and

0:37:36.600 --> 0:37:40.160
<v Speaker 1>what to do. Um that whatever lives there and eats

0:37:40.200 --> 0:37:43.000
<v Speaker 1>there is going to have the advantage. Well, the kill

0:37:43.080 --> 0:37:45.000
<v Speaker 1>room analogy you had is a good one. It's also

0:37:45.080 --> 0:37:46.920
<v Speaker 1>like at the end of Silence of the Lambs when

0:37:47.400 --> 0:37:51.200
<v Speaker 1>when Joe Foster goes into Buffalo Bill's house exactly exactly

0:37:51.280 --> 0:37:54.760
<v Speaker 1>like that and then even more complixate the drop on her. Yeah,

0:37:54.800 --> 0:37:57.319
<v Speaker 1>he's got the drop, but imagine if he also had

0:37:57.360 --> 0:38:01.239
<v Speaker 1>a decoy involved as well. What because there there are

0:38:01.280 --> 0:38:05.800
<v Speaker 1>these spiders known as sly closest spiders and they create

0:38:06.000 --> 0:38:09.640
<v Speaker 1>a double of themselves. They they they essentially craft a

0:38:09.719 --> 0:38:14.120
<v Speaker 1>large spider from leaves, debris, and dead insect parts. Have

0:38:14.239 --> 0:38:17.040
<v Speaker 1>it in the web. Yeah, in this way, you know,

0:38:17.080 --> 0:38:20.960
<v Speaker 1>confuses predators specifically, So if the spider is disturbed, it

0:38:21.040 --> 0:38:24.600
<v Speaker 1>vibrates its body but once so it's primarily defensive technique

0:38:24.719 --> 0:38:27.719
<v Speaker 1>against things that want to eat the spider. But I

0:38:27.719 --> 0:38:29.840
<v Speaker 1>guess that would also be true if you had random

0:38:29.880 --> 0:38:35.040
<v Speaker 1>Jodie Foster's random Clarice starlings wandering into your kill room

0:38:35.040 --> 0:38:37.520
<v Speaker 1>and trying to apprehend you. Well, yes, I mean, Buffalo

0:38:37.560 --> 0:38:40.440
<v Speaker 1>Bill does have to defend himself against Jodie Foster. She

0:38:40.600 --> 0:38:42.279
<v Speaker 1>was there to catch him, and she has a gun.

0:38:43.120 --> 0:38:45.160
<v Speaker 1>But of course the trap stone in there. Do they

0:38:45.360 --> 0:38:47.880
<v Speaker 1>Oh no, no, they get rather complicated, especially when you

0:38:47.880 --> 0:38:50.919
<v Speaker 1>start looking at trap door spiders. Can you imagine this

0:38:51.080 --> 0:38:54.359
<v Speaker 1>on the human scale to scale? Ups wandering along some

0:38:54.480 --> 0:38:59.360
<v Speaker 1>dry ground and suddenly the ground under you shifts. What's happening?

0:39:00.120 --> 0:39:01.960
<v Speaker 1>I know? Yeah, this is perfect, this is um I

0:39:01.960 --> 0:39:04.000
<v Speaker 1>guess to put this in horror movie terms as well,

0:39:04.040 --> 0:39:06.399
<v Speaker 1>this would be like a a Saw movie kind of thing.

0:39:06.440 --> 0:39:09.920
<v Speaker 1>I can't think of anything else recent where anyone's actually

0:39:09.960 --> 0:39:12.960
<v Speaker 1>busting out a trap door. Uh you know, it used

0:39:13.000 --> 0:39:16.319
<v Speaker 1>to be the standard Bond villain thing. But yeah. Trap

0:39:16.360 --> 0:39:21.560
<v Speaker 1>door spiders prey on larger terrestrial anthropods and even occasionally

0:39:21.560 --> 0:39:24.480
<v Speaker 1>on small lizards. They build tube like tunnels in the

0:39:24.520 --> 0:39:29.520
<v Speaker 1>sides of banks, in disturbed areas, along natural insect walkways.

0:39:29.560 --> 0:39:31.640
<v Speaker 1>They dig the tunnel, reinforce it with a mixture of

0:39:31.680 --> 0:39:34.239
<v Speaker 1>earth and saliva, then a layer of silk, and then

0:39:34.280 --> 0:39:36.440
<v Speaker 1>there's a door. So there are two types. There's the

0:39:36.520 --> 0:39:39.239
<v Speaker 1>cork tight door, which is thick and fitted. The other

0:39:39.360 --> 0:39:41.440
<v Speaker 1>is a wafer type door, which is a sheet of

0:39:41.480 --> 0:39:45.759
<v Speaker 1>silk and dirt. Both are silk hinged. So they're really

0:39:45.840 --> 0:39:49.279
<v Speaker 1>creating a rather complex structures here. Now, some species keep

0:39:49.280 --> 0:39:52.440
<v Speaker 1>it simple, others craft branching tunnels with multiple doors. The

0:39:52.480 --> 0:39:55.440
<v Speaker 1>species also differ as to whether the tunnels are simple

0:39:55.560 --> 0:39:58.120
<v Speaker 1>or branching with multiple doors. So I guess it's not

0:39:58.200 --> 0:40:00.279
<v Speaker 1>so much a jigsaw kind of scenario, and that you're

0:40:00.280 --> 0:40:03.879
<v Speaker 1>falling in, but something is in there, uh, in its

0:40:03.920 --> 0:40:06.880
<v Speaker 1>little disguised k ready to jump out and get you.

0:40:07.160 --> 0:40:10.160
<v Speaker 1>That is classic horror movie fodder. That's that's good stuff.

0:40:10.160 --> 0:40:13.520
<v Speaker 1>But also, uh, we should talk about the other types

0:40:13.560 --> 0:40:16.880
<v Speaker 1>of spider predation. Now, of course, all spiders produce silk,

0:40:17.000 --> 0:40:19.600
<v Speaker 1>but not all of them use it to spin structures

0:40:19.600 --> 0:40:21.640
<v Speaker 1>with it. Some of them make I don't know what

0:40:21.680 --> 0:40:24.120
<v Speaker 1>would you even call it, more like a weapon with it.

0:40:25.000 --> 0:40:27.640
<v Speaker 1>So how how about the Bullos spider. Oh yeah, they

0:40:28.000 --> 0:40:30.480
<v Speaker 1>hunt by using a sticky capture blob of silk at

0:40:30.520 --> 0:40:33.160
<v Speaker 1>the end of a line, which scientists called bulas. And

0:40:33.200 --> 0:40:35.600
<v Speaker 1>if you see video of this, they actually spin it

0:40:35.680 --> 0:40:39.040
<v Speaker 1>around like a lasso, like it'll be hanging from a web,

0:40:39.160 --> 0:40:41.759
<v Speaker 1>spinning this line of silk around in the air and

0:40:41.800 --> 0:40:45.799
<v Speaker 1>then snagging them off with it. So, yeah, that's a

0:40:45.800 --> 0:40:47.880
<v Speaker 1>great example. It's using it like a like a grappling

0:40:47.880 --> 0:40:52.799
<v Speaker 1>hook or like like scorpions, Harpoon and Mortal Kombat. Right, Oh,

0:40:52.880 --> 0:40:55.359
<v Speaker 1>that's good. And then on top of that, you have

0:40:56.000 --> 0:40:59.480
<v Speaker 1>net casting spiders as well. When the prey approaches, the

0:40:59.480 --> 0:41:01.879
<v Speaker 1>spider will stretch the net two or three times it's

0:41:02.120 --> 0:41:05.759
<v Speaker 1>relaxed size, and then propel itself onto the prey, entangling

0:41:05.760 --> 0:41:07.640
<v Speaker 1>it with the web. So these would be like the

0:41:07.960 --> 0:41:10.120
<v Speaker 1>kind of like the gladiators with the trident. I guess

0:41:10.640 --> 0:41:14.319
<v Speaker 1>uh in uh in gladiatorial combat. Oh, would they have

0:41:14.440 --> 0:41:17.480
<v Speaker 1>like the net like the fisherman styleators? Right? They got

0:41:17.480 --> 0:41:20.839
<v Speaker 1>a net in a pokeia and in some sometimes there

0:41:20.880 --> 0:41:22.920
<v Speaker 1>are some spiders of this type that have an extra

0:41:22.960 --> 0:41:25.319
<v Speaker 1>technique that they used to help them pick out their prey.

0:41:25.360 --> 0:41:27.880
<v Speaker 1>At night. This is pretty ingenious. So you have a

0:41:27.920 --> 0:41:31.680
<v Speaker 1>particular species of the spiders that, in addition to any

0:41:31.719 --> 0:41:34.040
<v Speaker 1>kind of structure they may have built, they'll also uh

0:41:34.160 --> 0:41:38.200
<v Speaker 1>spray feces on the ground which will dry white, and

0:41:38.200 --> 0:41:40.560
<v Speaker 1>then any dark animal that has to run across it,

0:41:40.920 --> 0:41:43.319
<v Speaker 1>they're gonna stand out. Oh, I still get them. So

0:41:43.360 --> 0:41:47.120
<v Speaker 1>there's so many levels of of not only utilizing traps,

0:41:47.120 --> 0:41:50.960
<v Speaker 1>but really maximizing the environment, creating a keep coming back

0:41:51.000 --> 0:41:53.440
<v Speaker 1>to the kill zone in the kill room example, creating

0:41:53.440 --> 0:41:56.840
<v Speaker 1>a custom eyed environment that they have total mastery of.

0:41:57.280 --> 0:41:59.799
<v Speaker 1>Yet again, it's hard to imagine exactly what this would

0:41:59.800 --> 0:42:03.000
<v Speaker 1>be like scaled up to monster movie size spiders. I

0:42:03.320 --> 0:42:05.719
<v Speaker 1>don't know if it really translates, right, I Mean, it's

0:42:05.760 --> 0:42:08.319
<v Speaker 1>yet another one of those things where sometimes it's hard

0:42:08.360 --> 0:42:10.680
<v Speaker 1>to fit this to our to our weird premise. A

0:42:10.760 --> 0:42:13.480
<v Speaker 1>lot of this stuff seems to work on the small scale.

0:42:14.200 --> 0:42:17.240
<v Speaker 1>Uh Like, I don't know would would would would spring

0:42:17.280 --> 0:42:19.680
<v Speaker 1>the ground with fcs work for for a giant one

0:42:19.680 --> 0:42:22.960
<v Speaker 1>of these things? I mean, I guess we just have

0:42:23.040 --> 0:42:25.200
<v Speaker 1>to stay in the light, right I guess? And you know,

0:42:25.480 --> 0:42:27.920
<v Speaker 1>would a large spider to prey on humans have to

0:42:27.960 --> 0:42:31.240
<v Speaker 1>get even more inventive. Would it actually use its webbing

0:42:31.280 --> 0:42:35.239
<v Speaker 1>and it's decoys to create like an entire, entirely functional

0:42:35.760 --> 0:42:40.680
<v Speaker 1>um rest stop to create a party with free beer.

0:42:41.760 --> 0:42:43.480
<v Speaker 1>It's like, sorry, it's all spider silk. You don't know.

0:42:43.480 --> 0:42:45.440
<v Speaker 1>Do you go to drink it? Yeah? So there are

0:42:45.440 --> 0:42:48.520
<v Speaker 1>lots of methods of spider predation that obviously involves silk

0:42:48.560 --> 0:42:51.319
<v Speaker 1>in one way or another, creating traps and stuff like that.

0:42:51.360 --> 0:42:55.520
<v Speaker 1>But there's also the much older, simpler, more universal hunting

0:42:55.560 --> 0:43:00.880
<v Speaker 1>tactic where they just chase you down, Just run you down, bite, bite,

0:43:00.880 --> 0:43:02.960
<v Speaker 1>and subdue. Yeah, maybe jump out from behind a tree

0:43:03.040 --> 0:43:05.760
<v Speaker 1>or something. But so I was wondering about the speed

0:43:05.800 --> 0:43:08.480
<v Speaker 1>of spiders. Try to imagine we've got the scaled up

0:43:08.520 --> 0:43:12.319
<v Speaker 1>spider again, ignoring all the physics constraints, how fast would

0:43:12.320 --> 0:43:15.319
<v Speaker 1>it move if it moved relative to its speed on

0:43:15.360 --> 0:43:20.359
<v Speaker 1>the ground. The answer is hilarious. So, so I wanna

0:43:20.719 --> 0:43:25.600
<v Speaker 1>reference that. There's some papers on spider gate characteristics and

0:43:25.600 --> 0:43:29.040
<v Speaker 1>and running speed among spider species that are like these

0:43:29.160 --> 0:43:34.560
<v Speaker 1>grass funnel web spiders. Hololena is the genus, and research

0:43:34.600 --> 0:43:37.759
<v Speaker 1>has shown that under experimental conditions, a couple of species

0:43:37.800 --> 0:43:41.040
<v Speaker 1>of funnel web spinning spiders and the whole landa genus

0:43:41.200 --> 0:43:46.400
<v Speaker 1>can perform sprints occasionally faster than about fifty centimeters per second,

0:43:46.719 --> 0:43:50.560
<v Speaker 1>which works out to about seventy body lengths per second

0:43:50.920 --> 0:43:54.880
<v Speaker 1>for these spiders. Now, imagine if you could sprint up

0:43:54.880 --> 0:43:58.520
<v Speaker 1>to seventy body lengths per second. If you're six ft tall,

0:43:59.280 --> 0:44:02.479
<v Speaker 1>that's a hundred three cimeters. That means if you could

0:44:02.520 --> 0:44:05.640
<v Speaker 1>move as fast as this spider relative to your own

0:44:05.680 --> 0:44:08.200
<v Speaker 1>body size, you would be able to move a hundred

0:44:08.239 --> 0:44:11.520
<v Speaker 1>and twenty eight meters per second. That's about one point

0:44:11.560 --> 0:44:16.320
<v Speaker 1>for American football fields per second. Now, if you imagine

0:44:16.360 --> 0:44:19.440
<v Speaker 1>a predator that could kill you could sprint up to

0:44:19.600 --> 0:44:22.600
<v Speaker 1>seventy body lengths per second. If our giant spider has

0:44:22.640 --> 0:44:25.160
<v Speaker 1>I don't know, a ten meter body length and can

0:44:25.200 --> 0:44:29.360
<v Speaker 1>sprint seventy body lengths per second, that's seven d I

0:44:29.400 --> 0:44:32.480
<v Speaker 1>mean that obviously that's not going to happen in reality,

0:44:32.520 --> 0:44:35.239
<v Speaker 1>but these things would be able to chase you down

0:44:35.280 --> 0:44:39.600
<v Speaker 1>in ways that are unbelievable to the human mind. Oh wow, Yeah,

0:44:39.680 --> 0:44:42.160
<v Speaker 1>it's it's hard to even imagine how that would scale up.

0:44:43.600 --> 0:44:45.040
<v Speaker 1>The best I can do is to try and imagine

0:44:45.040 --> 0:44:48.160
<v Speaker 1>it taking place in like a tensent dragons tiled map

0:44:48.480 --> 0:44:51.520
<v Speaker 1>the grid and even then that's a ridiculous amount of speed.

0:44:51.840 --> 0:44:55.759
<v Speaker 1>Why would you have that many grid squares battlefield that big?

0:44:55.800 --> 0:45:01.000
<v Speaker 1>It's unmanageable. Contact your d m okay, So other fun

0:45:01.040 --> 0:45:04.759
<v Speaker 1>adventures in predation. There is one family of spiders that

0:45:04.920 --> 0:45:08.760
<v Speaker 1>I love, known as the labor a day the Allobrids.

0:45:09.440 --> 0:45:13.760
<v Speaker 1>Oh yeah, these guys are great because they they actually

0:45:13.800 --> 0:45:16.160
<v Speaker 1>crush you. And I say you, I'm speaking of course

0:45:16.200 --> 0:45:20.520
<v Speaker 1>to small insects, but they crushed their prey with their webbing.

0:45:20.520 --> 0:45:23.600
<v Speaker 1>They wrap them up and essentially a body crushing iron

0:45:23.719 --> 0:45:27.560
<v Speaker 1>maiden of silk. Yeah, there's a species particularly we've read about,

0:45:27.560 --> 0:45:31.680
<v Speaker 1>the philip Pinella of Assinna And yeah, they have this

0:45:31.800 --> 0:45:35.800
<v Speaker 1>method of wrapping you in silk that is so tight

0:45:35.920 --> 0:45:39.200
<v Speaker 1>that your body structures are crushed. In word, they say

0:45:39.200 --> 0:45:42.920
<v Speaker 1>that the legs snap that like the eyes buckle in.

0:45:44.280 --> 0:45:46.719
<v Speaker 1>It's it's pretty ground it. It reminds me of I

0:45:46.719 --> 0:45:49.160
<v Speaker 1>think there's a scene in color Clowns from Outer Space

0:45:49.480 --> 0:45:52.360
<v Speaker 1>where they utilize some sort of silly string contraption that

0:45:52.440 --> 0:45:55.680
<v Speaker 1>works like this. But but yeah, the researchers have apparently

0:45:55.719 --> 0:45:59.600
<v Speaker 1>observed these spiders spending a hundred times as much effort

0:45:59.680 --> 0:46:03.160
<v Speaker 1>over an hour to wrap a prey in eighty meters

0:46:03.239 --> 0:46:05.240
<v Speaker 1>of silk. So that's two d and sixty two feet,

0:46:06.200 --> 0:46:12.040
<v Speaker 1>which seems crazy. Yeah, that that's not scaled to what

0:46:12.080 --> 0:46:15.040
<v Speaker 1>we're talking about. That's just like the tiny spider. Yeah,

0:46:15.080 --> 0:46:17.800
<v Speaker 1>producing that much silk to to wrap the prey this type.

0:46:18.239 --> 0:46:21.120
<v Speaker 1>And actually I've got some more interesting stuff about how

0:46:21.239 --> 0:46:24.839
<v Speaker 1>the species eats in a bit. But so one reason

0:46:24.880 --> 0:46:26.920
<v Speaker 1>they need to do this is because these are actually

0:46:27.000 --> 0:46:29.759
<v Speaker 1>not venom producing spiders, that's right. They don't have the

0:46:30.080 --> 0:46:32.759
<v Speaker 1>powerful bite. So what do they gotta do? What do

0:46:32.840 --> 0:46:36.360
<v Speaker 1>they how do they start softening up their prey to consume.

0:46:36.680 --> 0:46:38.960
<v Speaker 1>They have to drool all over it. But you have

0:46:39.040 --> 0:46:42.480
<v Speaker 1>a strate jacket, tighten it as much as possible, and

0:46:42.520 --> 0:46:45.000
<v Speaker 1>then begin the vomiting. That seems to be the predominant

0:46:45.040 --> 0:46:47.840
<v Speaker 1>theory is that they basically they know they're gonna have

0:46:47.840 --> 0:46:50.240
<v Speaker 1>to drool over this stuff, so they want as small

0:46:50.239 --> 0:46:52.520
<v Speaker 1>a target as possible. It's just go ahead and crunch

0:46:52.560 --> 0:46:55.600
<v Speaker 1>it all up, make something small, so I'm conserving my

0:46:55.719 --> 0:46:58.920
<v Speaker 1>spider drool. Okay, well, let's get more into the details

0:46:59.040 --> 0:47:03.240
<v Speaker 1>of how they drool on you. And uh, that's maybe

0:47:03.239 --> 0:47:05.080
<v Speaker 1>even the nice way of putting it of what would

0:47:05.080 --> 0:47:09.320
<v Speaker 1>happen to you as the eating process actually begins. Now, first,

0:47:09.360 --> 0:47:11.960
<v Speaker 1>I guess we start with you being immobilized. You've been

0:47:11.960 --> 0:47:15.160
<v Speaker 1>caught in a trap by a trapdoor spider, in a web,

0:47:15.680 --> 0:47:18.000
<v Speaker 1>in a in a silk lasso, or you've just been

0:47:18.080 --> 0:47:21.080
<v Speaker 1>chased down and bitten. Uh. One of the things that's

0:47:21.080 --> 0:47:23.960
<v Speaker 1>gonna happen with pretty much all spiders except the labor

0:47:24.120 --> 0:47:27.920
<v Speaker 1>day and another genus known as or not genus another family.

0:47:27.960 --> 0:47:31.839
<v Speaker 1>I think the the hul archad today is that they're

0:47:31.840 --> 0:47:34.840
<v Speaker 1>all gonna have venom. And the venom glands are attached

0:47:34.880 --> 0:47:39.120
<v Speaker 1>to ducts that travel down the length of the collissarae,

0:47:39.520 --> 0:47:43.600
<v Speaker 1>and those are the mouth part structures right like the fangs.

0:47:43.680 --> 0:47:46.520
<v Speaker 1>You are attached to the end of the collissarae. And

0:47:46.560 --> 0:47:49.239
<v Speaker 1>then the ducts come down to a hole at the

0:47:49.280 --> 0:47:52.960
<v Speaker 1>tip of the collissarol fang, and they'll hit you with

0:47:53.080 --> 0:47:58.440
<v Speaker 1>that and rapidly contract their muscles to eject this cocktail

0:47:58.640 --> 0:48:01.480
<v Speaker 1>of venom into you. Now, the venoms vary from species

0:48:01.520 --> 0:48:05.160
<v Speaker 1>to species, and the venom cocktail is generally well, it's

0:48:05.160 --> 0:48:08.480
<v Speaker 1>a cocktail, it's heterogeneous. Right, So it means they contain

0:48:08.600 --> 0:48:12.640
<v Speaker 1>multiple different toxins and different chemicals doing different jobs. So

0:48:12.680 --> 0:48:16.400
<v Speaker 1>a common spider toxin is going to be a neurotoxic polypeptide.

0:48:16.400 --> 0:48:20.160
<v Speaker 1>It's a chain of amino acids that attacks the nervous system. Uh,

0:48:20.160 --> 0:48:23.400
<v Speaker 1>and the prey can expect to experience some distressing systemic

0:48:23.440 --> 0:48:26.960
<v Speaker 1>effects and paralysis. But different spiders are gonna gonna hit

0:48:27.040 --> 0:48:29.279
<v Speaker 1>you with different venoms. There, They're gonna be different things.

0:48:29.360 --> 0:48:32.200
<v Speaker 1>You'd have to expect. We can't. There's no one size

0:48:32.200 --> 0:48:35.360
<v Speaker 1>fits all. But from this stage it's generally going to

0:48:35.400 --> 0:48:38.239
<v Speaker 1>be on to the eating. All Right, we're gonna take

0:48:38.239 --> 0:48:40.759
<v Speaker 1>a quick break and when we come back, we will

0:48:40.800 --> 0:48:52.000
<v Speaker 1>be consumed. Alright, we're back. The spiders have captured us,

0:48:52.080 --> 0:48:55.239
<v Speaker 1>and now they're going to consume us. Right, So the

0:48:55.320 --> 0:48:58.840
<v Speaker 1>spider has you immobilized, perhaps wrapped in a cocoon of silk,

0:48:59.239 --> 0:49:02.840
<v Speaker 1>may be subdued with a venomous bite, and the purpose

0:49:02.960 --> 0:49:05.799
<v Speaker 1>of the venom is to subdue and paralyze the prey.

0:49:05.840 --> 0:49:07.799
<v Speaker 1>I've read that the fact that it often kills the

0:49:07.800 --> 0:49:11.640
<v Speaker 1>prey is technically an unnecessary side effect. Plus, we should

0:49:11.719 --> 0:49:14.680
<v Speaker 1>keep in mind that venom is designed to work primarily

0:49:14.680 --> 0:49:18.239
<v Speaker 1>against the spiders major food source, which is arthropods other

0:49:18.600 --> 0:49:23.279
<v Speaker 1>invertebrate insects. So you are not an arthropod unless you are,

0:49:23.320 --> 0:49:28.160
<v Speaker 1>in which case we're preparing Earth for your arrival. But

0:49:28.200 --> 0:49:31.520
<v Speaker 1>when the spider starts to eat you, you a mammal,

0:49:32.040 --> 0:49:34.239
<v Speaker 1>I don't know what's going to happen. Maybe you'd still

0:49:34.280 --> 0:49:37.040
<v Speaker 1>be alive and paralyzed, you might be dead. It's hard

0:49:37.080 --> 0:49:40.080
<v Speaker 1>to say. It kind of comes down to did this

0:49:40.080 --> 0:49:45.680
<v Speaker 1>thing evolved to prey on humans? How? Atomic radiation? Robert? Yeah,

0:49:45.719 --> 0:49:48.000
<v Speaker 1>but that's the thing, Like it's a it's a tool

0:49:48.040 --> 0:49:52.200
<v Speaker 1>for a particular particular purpose. And unless you're dealing with

0:49:52.239 --> 0:49:55.920
<v Speaker 1>some other worldly environment where humans and giant spiders have

0:49:56.040 --> 0:49:59.680
<v Speaker 1>co evolved for this relationship, it's gonna be a little uncertain.

0:49:59.680 --> 0:50:02.959
<v Speaker 1>It's to be a little off exactly right. So how

0:50:03.000 --> 0:50:06.800
<v Speaker 1>does it start to eat you? Well, generally spiders consume

0:50:07.000 --> 0:50:10.120
<v Speaker 1>a liquid diet. But I'm not a liquid, Robert, or

0:50:10.160 --> 0:50:14.279
<v Speaker 1>you a liquid I'm mostly liquid. But you know, I

0:50:14.280 --> 0:50:16.319
<v Speaker 1>mean if I were to go and eat you, you

0:50:16.320 --> 0:50:18.600
<v Speaker 1>would not you. I mean, your body has lots of

0:50:18.640 --> 0:50:21.480
<v Speaker 1>liquids in it, incorporated into cell structures, you can have

0:50:21.520 --> 0:50:27.120
<v Speaker 1>a lot of valid stuff. Yeah, So so something's going

0:50:27.160 --> 0:50:30.320
<v Speaker 1>to have to happen here. So what's going to happen

0:50:30.440 --> 0:50:33.839
<v Speaker 1>is that the spider begins to vomit on you. This

0:50:33.880 --> 0:50:35.799
<v Speaker 1>can happen in a couple of different ways, which we'll

0:50:35.840 --> 0:50:38.200
<v Speaker 1>get to in a moment. But the essential processes that

0:50:38.239 --> 0:50:42.920
<v Speaker 1>the spider ejects digestive fluids onto you, and these digestive

0:50:42.960 --> 0:50:47.680
<v Speaker 1>fluids contain enzymes. Uh, the fluids are truly caustic. And

0:50:47.719 --> 0:50:50.640
<v Speaker 1>here's one example to illustrate, which I thought was fascinating

0:50:50.680 --> 0:50:55.600
<v Speaker 1>from a study in the Journal of a Racknology. So

0:50:55.600 --> 0:50:58.800
<v Speaker 1>we're gonna go back to the lubri day. The spiders

0:50:58.840 --> 0:51:01.960
<v Speaker 1>that don't have their own venom glans, right, and they

0:51:01.960 --> 0:51:05.160
<v Speaker 1>crush you with that silk structure. So, uh, this is

0:51:05.200 --> 0:51:09.080
<v Speaker 1>the same species we mentioned earlier, the Filipinella vicinna. They

0:51:09.160 --> 0:51:13.719
<v Speaker 1>usually pose on their web in a strange posture if

0:51:13.760 --> 0:51:16.719
<v Speaker 1>you've ever seen this. They keep their legs folded in

0:51:16.960 --> 0:51:20.520
<v Speaker 1>against the body. And it's been hypothesized that the reason

0:51:20.600 --> 0:51:23.400
<v Speaker 1>they pose in the web like this is to avoid

0:51:23.520 --> 0:51:26.200
<v Speaker 1>visually signaling predators. So there might be a bird that

0:51:26.280 --> 0:51:28.520
<v Speaker 1>wants to eat spiders or something. It knows what a

0:51:28.520 --> 0:51:31.160
<v Speaker 1>spider looks like. But if you don't pose in a

0:51:31.200 --> 0:51:33.280
<v Speaker 1>way that gives away the fact that you're a spider,

0:51:33.320 --> 0:51:36.759
<v Speaker 1>the burden might not recognize you as prey um. But

0:51:37.239 --> 0:51:41.000
<v Speaker 1>when the elaborated begins to eat, it does something strange.

0:51:41.120 --> 0:51:44.520
<v Speaker 1>It gets out of its regular posture and spreads its

0:51:44.560 --> 0:51:48.080
<v Speaker 1>anterior legs or the front legs wide apart. It holds

0:51:48.120 --> 0:51:52.080
<v Speaker 1>them way back. Why does it do that? Well, the

0:51:52.120 --> 0:51:54.080
<v Speaker 1>authors of the study point out that, you know, the

0:51:54.120 --> 0:51:58.359
<v Speaker 1>spider's method of eating this illobred is to rapids prey

0:51:58.440 --> 0:52:02.080
<v Speaker 1>in this ridiculously tight amount of silk, compress it into

0:52:02.080 --> 0:52:05.360
<v Speaker 1>a compact package like a garbage compactor, and then just

0:52:05.600 --> 0:52:08.920
<v Speaker 1>vomit all over the entire thing. So most spiders are

0:52:08.920 --> 0:52:12.080
<v Speaker 1>going to take a slightly different route where they eject

0:52:12.120 --> 0:52:15.560
<v Speaker 1>these digestive enzymes through a small hole in the shell

0:52:15.680 --> 0:52:19.000
<v Speaker 1>of the prey insect or over a small surface at

0:52:19.000 --> 0:52:22.239
<v Speaker 1>a time when they're eating not pivicina. This will just

0:52:22.360 --> 0:52:27.160
<v Speaker 1>slather the entire thing. Essentially, it's making a huge mess.

0:52:27.200 --> 0:52:30.360
<v Speaker 1>So the researchers asks, huh, I wonder if the spider

0:52:30.480 --> 0:52:34.680
<v Speaker 1>it's is holding its anterior legs away from this mess,

0:52:34.719 --> 0:52:38.040
<v Speaker 1>because the same digestive enzymes it's using to dissolve its

0:52:38.080 --> 0:52:42.200
<v Speaker 1>prey would also dissolve its own body, and their research

0:52:42.239 --> 0:52:44.920
<v Speaker 1>found bingo, that does appear to be what's happening. The

0:52:44.960 --> 0:52:48.680
<v Speaker 1>authors found that the spider's digestive enzymes, when applied to

0:52:48.800 --> 0:52:53.360
<v Speaker 1>detached legs from the same spiders species, uh, they caused

0:52:53.400 --> 0:52:56.400
<v Speaker 1>the set a, meaning the bristles, to fall off of

0:52:56.440 --> 0:53:00.000
<v Speaker 1>the legs, and they also cause damage to the intersegment

0:53:00.000 --> 0:53:03.880
<v Speaker 1>mental membranes between the different parts of the legs. So

0:53:04.200 --> 0:53:08.040
<v Speaker 1>imagine if you had to eat by so you've got

0:53:08.040 --> 0:53:10.040
<v Speaker 1>a plate you're sitting down with, you've got a hamburger

0:53:10.080 --> 0:53:13.080
<v Speaker 1>on it, and you have to eat by vomiting Hollywood

0:53:13.120 --> 0:53:18.240
<v Speaker 1>acid all over your food. Yeah uh. And then also

0:53:18.360 --> 0:53:21.000
<v Speaker 1>that stuff would give you chemical burns if you touched

0:53:21.040 --> 0:53:23.520
<v Speaker 1>it with your own hands, so you sort of have

0:53:23.560 --> 0:53:26.840
<v Speaker 1>to like vomit all over and then hold your arms

0:53:26.880 --> 0:53:31.239
<v Speaker 1>back and slurp it up. But anyway, let's get back

0:53:31.280 --> 0:53:33.400
<v Speaker 1>to being the prey. You're not the spider in this scenario.

0:53:33.560 --> 0:53:36.600
<v Speaker 1>You're the prey, so obviously you've been immobilized. The spider

0:53:36.640 --> 0:53:40.080
<v Speaker 1>starts to apply this digestive fluid to you. Now, obviously,

0:53:40.120 --> 0:53:43.200
<v Speaker 1>if you've been attacked by a giant uh P vicinna,

0:53:43.520 --> 0:53:45.560
<v Speaker 1>you're gonna be crushed into a tiny ball with a

0:53:45.600 --> 0:53:48.040
<v Speaker 1>tight wrapping of silk, so we can basically say it's

0:53:48.120 --> 0:53:51.040
<v Speaker 1>lights out. Then the spider will dissolve your entire body

0:53:51.080 --> 0:53:55.080
<v Speaker 1>with these enzymes and suck up your liquefying body parts,

0:53:55.080 --> 0:53:57.600
<v Speaker 1>holding its legs back in a very dainty fashion as

0:53:57.600 --> 0:54:01.200
<v Speaker 1>it does so. Um, but well, what's gonna happen if

0:54:01.200 --> 0:54:04.000
<v Speaker 1>it's not this species, if we're dealing with other types

0:54:04.000 --> 0:54:06.040
<v Speaker 1>of spiders, And here a lot of my information is

0:54:06.080 --> 0:54:09.239
<v Speaker 1>going to come from a really delightful arachnology book called

0:54:09.280 --> 0:54:12.799
<v Speaker 1>The Biology of Spiders by rain or Felix. Uh So,

0:54:13.000 --> 0:54:16.319
<v Speaker 1>for most types of spiders, feeding differs significantly based on

0:54:16.400 --> 0:54:19.800
<v Speaker 1>whether or not the spider has what's called calyssral teeth.

0:54:20.280 --> 0:54:22.520
<v Speaker 1>So the spider have the calyscera, you know, these are

0:54:22.560 --> 0:54:24.400
<v Speaker 1>the mouth parts that have the fangs at the end

0:54:24.440 --> 0:54:29.319
<v Speaker 1>of them. But some spiders have have these these teeth structures,

0:54:29.320 --> 0:54:32.440
<v Speaker 1>these sort of grinding surfaces on the inside of them,

0:54:32.480 --> 0:54:34.600
<v Speaker 1>and some have very few of these or don't have

0:54:34.680 --> 0:54:37.840
<v Speaker 1>these structures at all either way, The general processes that

0:54:37.920 --> 0:54:42.000
<v Speaker 1>the spider is going to barf, it's gonna regurgitate some

0:54:42.120 --> 0:54:46.239
<v Speaker 1>digestive fluid onto the prey, wait a few seconds for

0:54:46.280 --> 0:54:49.200
<v Speaker 1>it to dissolve some tissues, and then it's gonna suck

0:54:49.320 --> 0:54:54.120
<v Speaker 1>that liquid back in and then repeat at victori um. Uh.

0:54:54.280 --> 0:54:57.440
<v Speaker 1>So what happens when the spiders don't have these teeth

0:54:57.480 --> 0:55:01.279
<v Speaker 1>I mentioned the calyssol teeth or have a few of them. Uh.

0:55:01.280 --> 0:55:03.400
<v Speaker 1>There are a few families of spiders that are like this.

0:55:03.520 --> 0:55:07.239
<v Speaker 1>So there's the terridda day, the comb footed spiders or

0:55:07.280 --> 0:55:10.080
<v Speaker 1>tangle web spiders, and this is a big family of

0:55:10.120 --> 0:55:13.600
<v Speaker 1>spiders that includes the Latrodectus genus, which are the widows.

0:55:14.760 --> 0:55:18.319
<v Speaker 1>And then also we're gonna include the thomisids with your

0:55:18.320 --> 0:55:22.520
<v Speaker 1>crab spiders. So these guys work typically by creating a

0:55:22.640 --> 0:55:25.799
<v Speaker 1>very tiny hole in the outer shell of the prey,

0:55:25.840 --> 0:55:30.080
<v Speaker 1>which they might poke with the calyscera, and then spitting

0:55:30.160 --> 0:55:34.120
<v Speaker 1>digestive fluid into the body cavity through the holes. That

0:55:34.200 --> 0:55:36.359
<v Speaker 1>makes sense. So you've got an insect with an outer

0:55:36.480 --> 0:55:39.640
<v Speaker 1>exoskeleton and you're gonna be stabbing a hole in the

0:55:39.680 --> 0:55:43.080
<v Speaker 1>outside and then just putting some of this digestive enzyme

0:55:43.239 --> 0:55:48.040
<v Speaker 1>inside through the hole. The process is continued until the

0:55:48.040 --> 0:55:50.880
<v Speaker 1>prey is sort of left as a dry empty shell

0:55:51.040 --> 0:55:53.840
<v Speaker 1>like the digestive enzymes in and then it sucks some

0:55:53.920 --> 0:55:58.040
<v Speaker 1>fluid out. It's kind of reminiscent of some some mummification

0:55:58.120 --> 0:56:00.680
<v Speaker 1>techniques have been employed. Really, you're gonna do about all

0:56:00.680 --> 0:56:04.560
<v Speaker 1>that nasty stuff inside the creature? Well, you can try

0:56:04.600 --> 0:56:06.799
<v Speaker 1>and drain it out, you can try and putrefy it

0:56:07.040 --> 0:56:10.840
<v Speaker 1>or what have you. And this is kind of like that. Okay, yeah,

0:56:10.920 --> 0:56:13.680
<v Speaker 1>Well you are essentially left with a dried up husk

0:56:13.680 --> 0:56:16.080
<v Speaker 1>of a creature which is mummy like and it's and

0:56:16.160 --> 0:56:20.640
<v Speaker 1>it's outer appearance at least, so in the end, most

0:56:20.680 --> 0:56:23.760
<v Speaker 1>of these interior tissues are going to be dissolved, sucked out,

0:56:23.800 --> 0:56:28.160
<v Speaker 1>and delicious. And to me, I I wonder if so,

0:56:28.320 --> 0:56:31.240
<v Speaker 1>I was left to wonder what a spider that works

0:56:31.280 --> 0:56:34.000
<v Speaker 1>this way would make of an animal with an indoskeleton

0:56:34.160 --> 0:56:37.840
<v Speaker 1>rather than an exo skeleton. So does the exo skeleton

0:56:37.960 --> 0:56:41.440
<v Speaker 1>work as an important type of container for the process,

0:56:41.520 --> 0:56:44.200
<v Speaker 1>if that makes any sense. Would a spider like this

0:56:44.960 --> 0:56:48.480
<v Speaker 1>trying to eat a mammal without an exo skeleton be

0:56:48.560 --> 0:56:50.760
<v Speaker 1>kind of like if we tried to eat a bowl

0:56:50.800 --> 0:56:54.880
<v Speaker 1>of soup without the bowl. Yeah, because it's essentially making

0:56:55.120 --> 0:56:58.160
<v Speaker 1>you into a soup inside your own axis skeleton. Right,

0:56:58.920 --> 0:57:02.400
<v Speaker 1>So I er, I don't know. Mammals might not be

0:57:02.560 --> 0:57:06.520
<v Speaker 1>all that that enticing to spiders like this, but then again,

0:57:06.560 --> 0:57:08.520
<v Speaker 1>I don't know. It could be they may find some

0:57:08.560 --> 0:57:10.719
<v Speaker 1>way around it. I mean they they have by and

0:57:10.840 --> 0:57:15.120
<v Speaker 1>large evolved to prey and eat up eat invertebrates, and

0:57:15.360 --> 0:57:19.080
<v Speaker 1>that's their realm of of influence. Yes, and also we're

0:57:19.080 --> 0:57:21.360
<v Speaker 1>gonna get to the toothy spiders in a second, but

0:57:21.480 --> 0:57:24.040
<v Speaker 1>first I want to hit a myth, Robert. I don't

0:57:24.080 --> 0:57:25.840
<v Speaker 1>know if you thought like this when you were a kid.

0:57:25.960 --> 0:57:27.800
<v Speaker 1>I definitely thought this when I was a kid, and

0:57:27.840 --> 0:57:30.360
<v Speaker 1>I know some people probably do think this, that spiders

0:57:30.960 --> 0:57:35.000
<v Speaker 1>suck the juices out of prey animals through their fangs.

0:57:35.360 --> 0:57:38.040
<v Speaker 1>Did you think this way? Um? I think I did.

0:57:38.080 --> 0:57:40.240
<v Speaker 1>I don't know how much of that was, like directly

0:57:40.320 --> 0:57:44.040
<v Speaker 1>due to science text in school or my or if

0:57:44.040 --> 0:57:46.520
<v Speaker 1>it had to do with something I picked up elsewhere

0:57:46.560 --> 0:57:49.840
<v Speaker 1>and cartoons or something. But vampires, I often think of

0:57:49.920 --> 0:57:52.680
<v Speaker 1>vampires this way, or I used to that they would

0:57:52.720 --> 0:57:55.400
<v Speaker 1>bite you with their fangs, and then it would be sucking,

0:57:55.480 --> 0:57:58.200
<v Speaker 1>not with like the mouth, through the esophagus in the stomach,

0:57:58.240 --> 0:58:00.280
<v Speaker 1>but the blood that they drained from me would be

0:58:00.320 --> 0:58:06.240
<v Speaker 1>going up through the fangs somehow into a blood receiving system. Anyway,

0:58:06.280 --> 0:58:08.320
<v Speaker 1>I think a lot of people think about spiders this way.

0:58:08.360 --> 0:58:10.920
<v Speaker 1>This is not the case. That the presence of venom

0:58:10.960 --> 0:58:14.400
<v Speaker 1>injecting fangs similar to hypodermic needles in a way, I think,

0:58:14.440 --> 0:58:17.880
<v Speaker 1>could be responsible for the mistaken assumption that the fangs

0:58:17.960 --> 0:58:21.800
<v Speaker 1>work both ways. But this is not true. That the fluid,

0:58:21.920 --> 0:58:25.760
<v Speaker 1>so the fangs inject the venom, but the fluids that

0:58:25.800 --> 0:58:27.800
<v Speaker 1>are coming out of the prey animal are coming in

0:58:27.920 --> 0:58:32.000
<v Speaker 1>through the mouth parts. The fangs are injectors. The spiders

0:58:32.000 --> 0:58:35.240
<v Speaker 1>do consume with a fluid sucking action, but this is

0:58:35.280 --> 0:58:38.200
<v Speaker 1>done through a mouth orifice powered by an order by

0:58:38.240 --> 0:58:40.919
<v Speaker 1>the by the pharynx, and by an organ known as

0:58:41.000 --> 0:58:45.240
<v Speaker 1>the sucking stomach. Like that's great, It's like a pump

0:58:45.800 --> 0:58:49.160
<v Speaker 1>that that gets you know, it creates this suction action

0:58:49.240 --> 0:58:52.640
<v Speaker 1>that pulls all that delicious fluid up through the mouth

0:58:52.720 --> 0:58:56.920
<v Speaker 1>parts and through the pharynx down into the digestive system.

0:58:57.000 --> 0:58:59.880
<v Speaker 1>But anyway, back to the spiders that do have the teeth,

0:59:00.200 --> 0:59:03.480
<v Speaker 1>So these are the ones that have these grinding surfaces

0:59:03.480 --> 0:59:07.480
<v Speaker 1>on their calycera. They perform instead a kind of rudimentary

0:59:07.680 --> 0:59:10.880
<v Speaker 1>grinding action with these surfaces. So in science we refer

0:59:10.960 --> 0:59:13.720
<v Speaker 1>to this as a mastication. It's a great word, but

0:59:13.760 --> 0:59:16.960
<v Speaker 1>it just means chewing. Uh. And so these spiders also

0:59:17.200 --> 0:59:20.800
<v Speaker 1>do the same thing. Essentially, they work by regurgitating digestive

0:59:20.840 --> 0:59:24.720
<v Speaker 1>fluids onto the prey that dissolves the prey tissues and

0:59:24.720 --> 0:59:27.880
<v Speaker 1>then slurping up dissolved body tissues. But in the process

0:59:28.280 --> 0:59:31.920
<v Speaker 1>they also use these calyssral teeth to chew and mash

0:59:32.080 --> 0:59:36.600
<v Speaker 1>the prey animal up into a ball of unrecognizable half

0:59:36.640 --> 0:59:42.040
<v Speaker 1>dissolved mush. So they tenderizing and supefying at the same time. Exactly,

0:59:42.080 --> 0:59:45.000
<v Speaker 1>They're they're they're creating bullus the same way you actually

0:59:45.040 --> 0:59:47.240
<v Speaker 1>do with your mouth. You know, they say when you

0:59:47.320 --> 0:59:49.640
<v Speaker 1>chew food in your mouth, you sort of chew into

0:59:49.680 --> 0:59:54.160
<v Speaker 1>a chew chewed up mash. This is really grows it

0:59:54.240 --> 0:59:57.400
<v Speaker 1>chewed up mashed up ball of food known sometimes as

0:59:57.440 --> 1:00:00.920
<v Speaker 1>a bullus, that you then swallow. Yeah. Next, I'm highly

1:00:01.000 --> 1:00:03.160
<v Speaker 1>encourage anyone next time you're eating, because I think about

1:00:03.200 --> 1:00:06.479
<v Speaker 1>this all the time from an episode we did a

1:00:06.480 --> 1:00:09.720
<v Speaker 1>few years back on digestion. But you can, actually, if

1:00:09.720 --> 1:00:12.480
<v Speaker 1>you're conscious of it, you'll find yourself sitting there chewing

1:00:12.600 --> 1:00:17.720
<v Speaker 1>and just feeling as your your mouth automatically liquefies um,

1:00:18.320 --> 1:00:21.040
<v Speaker 1>choose up and then forms all of this into a

1:00:21.120 --> 1:00:24.800
<v Speaker 1>slurry bolus that then goes down the throat. That's yeah, great,

1:00:25.520 --> 1:00:28.400
<v Speaker 1>But but what's it like to be that bolus? That's

1:00:28.520 --> 1:00:31.240
<v Speaker 1>that's what we're wondering today. I guess at this point

1:00:31.240 --> 1:00:33.840
<v Speaker 1>you're probably not aware of what's going on anymore, because

1:00:34.240 --> 1:00:38.960
<v Speaker 1>the mastication process um and the dissolving of the digestive

1:00:39.080 --> 1:00:41.880
<v Speaker 1>enzymes work together to sort of reduce you to an

1:00:41.960 --> 1:00:46.960
<v Speaker 1>unrecognizable ball of gunk. Uh So, you become this mush,

1:00:47.240 --> 1:00:49.880
<v Speaker 1>and then they consume you via the old in and

1:00:49.920 --> 1:00:53.400
<v Speaker 1>out that we discussed before in the end, leaving behind

1:00:53.560 --> 1:00:57.600
<v Speaker 1>only sort of indigestible parts like shells or maybe in

1:00:57.720 --> 1:01:01.840
<v Speaker 1>some rare cases, bones and feathers. Uh So, these spiders

1:01:01.880 --> 1:01:05.120
<v Speaker 1>also have a process for vomiting backup hard in edible

1:01:05.200 --> 1:01:08.560
<v Speaker 1>body parts that are accidentally slurped up along with nutritious

1:01:08.960 --> 1:01:13.480
<v Speaker 1>dissolved meat from the prey, not unlike an owl. Owls

1:01:13.520 --> 1:01:17.880
<v Speaker 1>do that. Owl pellets are an indigestible stuff that they

1:01:18.440 --> 1:01:21.120
<v Speaker 1>went back up vom. Oh. I always thought those came

1:01:21.120 --> 1:01:23.360
<v Speaker 1>out the other end. No, no, no, yeah, these kind

1:01:23.360 --> 1:01:25.760
<v Speaker 1>of these come out the mouth. No, yes, spiders actually

1:01:25.800 --> 1:01:28.320
<v Speaker 1>they produce pellets. This has been shown in research that

1:01:28.600 --> 1:01:31.520
<v Speaker 1>indigestible parts. They so they go down, they go down

1:01:31.560 --> 1:01:33.880
<v Speaker 1>the mouth parts and then they get sort of like

1:01:34.200 --> 1:01:36.720
<v Speaker 1>I believe, they get sort of caught by these uh,

1:01:36.880 --> 1:01:42.120
<v Speaker 1>pharyngeal muscles and by sete again these bristles structures that

1:01:42.200 --> 1:01:44.880
<v Speaker 1>sort of filter them and catch them. Stuff that's not

1:01:45.000 --> 1:01:47.120
<v Speaker 1>good to eat gets sort of bawled up and then

1:01:47.160 --> 1:01:53.880
<v Speaker 1>ejected back out. Interesting, delicious, But of course this brings

1:01:53.920 --> 1:01:57.120
<v Speaker 1>us back to the question though, what about vertebrates? Yeah,

1:01:57.280 --> 1:02:01.160
<v Speaker 1>we are vertebrates. Can we look to examples of spiders

1:02:01.240 --> 1:02:05.760
<v Speaker 1>preying on other vertebrates? If there were a giant spider,

1:02:05.800 --> 1:02:07.840
<v Speaker 1>would it even want to eat us? I mean, would

1:02:07.840 --> 1:02:10.800
<v Speaker 1>it just be looking for like, where are the you know,

1:02:10.960 --> 1:02:16.240
<v Speaker 1>equally sized insects for me to eat? Obviously, the primary

1:02:16.240 --> 1:02:18.840
<v Speaker 1>prey animals of most spiders are going to be other

1:02:19.000 --> 1:02:24.040
<v Speaker 1>arthropod invertebrates, mainly insects, But what happens when the food

1:02:24.120 --> 1:02:28.000
<v Speaker 1>chain runs backwards? Do spiders ever seemed to eat vertebrates

1:02:28.040 --> 1:02:31.960
<v Speaker 1>on purpose, even mammals. Yeah, yeah, this does happen. It

1:02:32.000 --> 1:02:36.200
<v Speaker 1>doesn't happen that often, but it does happen. One example

1:02:36.240 --> 1:02:40.080
<v Speaker 1>I want to look at is a paper by paper

1:02:40.160 --> 1:02:44.959
<v Speaker 1>in Plos one by Martin Knifefeller and Miriam Nornschild, and

1:02:45.280 --> 1:02:50.439
<v Speaker 1>this was called Bat Predation by Spiders. It's about what

1:02:50.520 --> 1:02:52.960
<v Speaker 1>you guess it is from the title. They tried to

1:02:53.680 --> 1:02:59.240
<v Speaker 1>catalog recorded instances of spider predation on bats. Sometimes a

1:02:59.320 --> 1:03:03.080
<v Speaker 1>bat meets an unfortunate and it gets stuck, entangled in

1:03:03.080 --> 1:03:07.560
<v Speaker 1>a spider web. Sometimes after that happens, the spider begins

1:03:07.600 --> 1:03:10.280
<v Speaker 1>to eat. So the author has judged that in many

1:03:10.360 --> 1:03:13.400
<v Speaker 1>of the recorded instances, it looked like what had happened

1:03:14.080 --> 1:03:16.600
<v Speaker 1>when a bat died in a spiderweb was what they

1:03:16.640 --> 1:03:19.720
<v Speaker 1>would call a non predatory death. The bat just got

1:03:19.720 --> 1:03:23.240
<v Speaker 1>caught in there, got exhausted or dehydrated or something, and

1:03:23.240 --> 1:03:26.240
<v Speaker 1>it died, and the spider didn't even bother feeding on it, didn't.

1:03:26.240 --> 1:03:28.280
<v Speaker 1>He probably like he didn't even know what to do

1:03:28.320 --> 1:03:31.919
<v Speaker 1>with it right. In other examples, however, they identified what

1:03:32.000 --> 1:03:35.600
<v Speaker 1>they thought looked like genuine predation where the spider appeared

1:03:35.640 --> 1:03:39.800
<v Speaker 1>to attack, kill, and then eat the captured bat. They

1:03:39.840 --> 1:03:42.919
<v Speaker 1>also point out that these cases of bat predation, where

1:03:43.040 --> 1:03:45.440
<v Speaker 1>it at least seemed to them that the spider was

1:03:45.520 --> 1:03:49.280
<v Speaker 1>genuinely preying on the bat, might inform our judgment of

1:03:49.320 --> 1:03:52.360
<v Speaker 1>a hypothesis, and this is not necessarily known, but it's

1:03:52.360 --> 1:03:57.720
<v Speaker 1>a hypothesis in arachnology, the large rare prey hypothesis. And

1:03:57.840 --> 1:04:01.600
<v Speaker 1>essentially what this suggests is that while most of the

1:04:01.640 --> 1:04:05.800
<v Speaker 1>prey animals that are captured by large orb weaving spiders

1:04:05.800 --> 1:04:08.520
<v Speaker 1>are going to be tied little insects of low nutritional

1:04:08.600 --> 1:04:14.200
<v Speaker 1>value quote, the occasional catch of large, energetically rewarding prey

1:04:14.240 --> 1:04:17.920
<v Speaker 1>may be essential in order to fulfill the reproductive needs

1:04:18.080 --> 1:04:22.160
<v Speaker 1>of large orb weaving spiders. So, according to this hypothesis,

1:04:22.200 --> 1:04:25.360
<v Speaker 1>if it's correct, you've got these spiders that most of

1:04:25.360 --> 1:04:28.280
<v Speaker 1>what they catch is just junk, it's insect garbage. Every

1:04:28.320 --> 1:04:31.280
<v Speaker 1>now and then they hit the jackpot. And when they

1:04:31.320 --> 1:04:33.800
<v Speaker 1>hit the jackpot with a really large insect like a

1:04:33.840 --> 1:04:37.760
<v Speaker 1>cicada or something, or perhaps even a mammal like a

1:04:37.800 --> 1:04:42.040
<v Speaker 1>bat or a frog or some other small vertebrate. They

1:04:42.040 --> 1:04:45.400
<v Speaker 1>get this huge nutritional windfall that allows them to have

1:04:45.960 --> 1:04:48.960
<v Speaker 1>a much greater chance of reproductive success. Is that kind

1:04:48.960 --> 1:04:50.439
<v Speaker 1>of like a criminal of this pulling off a lot

1:04:50.440 --> 1:04:54.280
<v Speaker 1>of petty little jobs, but still has to carry off

1:04:54.520 --> 1:04:58.000
<v Speaker 1>one big heist every so often to sustain things. It's

1:04:58.040 --> 1:05:00.480
<v Speaker 1>like the beginning of the sting, you know, the grifters

1:05:00.600 --> 1:05:02.680
<v Speaker 1>or knocking people over for a few bucks here and

1:05:02.680 --> 1:05:05.640
<v Speaker 1>there by stealing their wallets, until they accidentally steal the

1:05:05.640 --> 1:05:09.200
<v Speaker 1>wallet of a guy who's running money for an illegal casino,

1:05:09.400 --> 1:05:13.000
<v Speaker 1>and they got these thousands of dollars. But of course

1:05:13.040 --> 1:05:15.240
<v Speaker 1>in that scenario, the gangster then comes after them. I

1:05:15.240 --> 1:05:18.560
<v Speaker 1>don't know if there's but this underlies the problem of

1:05:18.560 --> 1:05:21.720
<v Speaker 1>going after larger prey. Do you see through throughout the

1:05:21.800 --> 1:05:24.720
<v Speaker 1>animal kingdom? And that's that, Yeah, the larger prey come

1:05:24.720 --> 1:05:27.120
<v Speaker 1>with greater risk. You gotta extend more, extend more energy,

1:05:27.400 --> 1:05:31.200
<v Speaker 1>possibly risk injuring yourself or even dying at the hands

1:05:31.200 --> 1:05:33.600
<v Speaker 1>of the larger prey that you're going after. It's a

1:05:33.960 --> 1:05:36.920
<v Speaker 1>it's a risk, but that's that's what that's. Great rewards

1:05:36.920 --> 1:05:41.600
<v Speaker 1>come with greater risk, so they do. Yeah, I was

1:05:41.680 --> 1:05:52.480
<v Speaker 1>eaten by a giant spider. Okay, so that's what it's

1:05:52.520 --> 1:05:54.640
<v Speaker 1>like to get eaten by a giant spider. I hope

1:05:54.640 --> 1:05:57.080
<v Speaker 1>you enjoyed it, and I and I hope you enjoy

1:05:57.240 --> 1:06:00.280
<v Speaker 1>being eaten by a giant spider because they are coming. Yes,

1:06:01.000 --> 1:06:05.360
<v Speaker 1>and uh, you know, we this is actually a great opportunity. Uh,

1:06:05.440 --> 1:06:08.040
<v Speaker 1>we just started a thing. We're experimenting with, a thing

1:06:08.080 --> 1:06:11.880
<v Speaker 1>where we're doing Facebook live videos and looking at trailer

1:06:11.880 --> 1:06:15.440
<v Speaker 1>footage from old films. So there might be a possibility

1:06:15.520 --> 1:06:17.680
<v Speaker 1>here with this episode. Oh, this could be great. We

1:06:17.720 --> 1:06:22.040
<v Speaker 1>could look at some some old nineteen fifties Spider Ma trailers. Yeah,

1:06:22.400 --> 1:06:25.080
<v Speaker 1>let's check in on our Facebook page and see if

1:06:25.080 --> 1:06:27.600
<v Speaker 1>that's happening. Maybe we can make that happen the Friday

1:06:27.600 --> 1:06:29.920
<v Speaker 1>after this airs. I just wanted to clarify I was

1:06:30.000 --> 1:06:32.320
<v Speaker 1>kidding about the spiders coming by the way, I meant

1:06:32.360 --> 1:06:34.880
<v Speaker 1>coming from space. I didn't want to suggest that I

1:06:34.920 --> 1:06:37.320
<v Speaker 1>think that we're there evolving in that direction. And some

1:06:37.360 --> 1:06:40.200
<v Speaker 1>people do listen to this show as they're falling asleep,

1:06:40.240 --> 1:06:43.320
<v Speaker 1>so I would hate for that thought to enter into

1:06:43.360 --> 1:06:48.680
<v Speaker 1>their vulnerable, uh semi dreaming mind and plant any seeds. Yeah,

1:06:48.760 --> 1:06:51.000
<v Speaker 1>we're not here to plant spider seeds in your head.

1:06:51.240 --> 1:06:53.440
<v Speaker 1>That's for the twenty seven spiders that crawl into your

1:06:53.440 --> 1:06:56.280
<v Speaker 1>mouth each night. Yeah, let me retreat and become responsible

1:06:56.320 --> 1:06:58.760
<v Speaker 1>for a moment in my final in my final moments here,

1:06:58.800 --> 1:07:01.720
<v Speaker 1>I want to remind you yet in spiders or your friend,

1:07:01.840 --> 1:07:04.280
<v Speaker 1>they're not your enemy, No reason to fight them. At

1:07:04.360 --> 1:07:07.400
<v Speaker 1>number two, there's never gonna be a giant spider on Earth.

1:07:08.880 --> 1:07:10.840
<v Speaker 1>All right. Well, hey, if you want to learn more
