1 00:00:00,120 --> 00:00:02,600 Speaker 1: Guess what, Mango? What's that? Will? All right? So I've 2 00:00:02,640 --> 00:00:05,080 Speaker 1: been looking at octopus facts all week, and I hope 3 00:00:05,080 --> 00:00:07,320 Speaker 1: you have too, because that's the episode we're recording right now. 4 00:00:07,360 --> 00:00:09,840 Speaker 1: But did you know that they love puzzles like they 5 00:00:09,880 --> 00:00:12,760 Speaker 1: actually kind of need them. I mean, it's not surprising 6 00:00:12,760 --> 00:00:14,920 Speaker 1: that they're smart. They're basically a giant heads with too 7 00:00:14,960 --> 00:00:18,040 Speaker 1: many legs. So I was reading about Louis the octopus. 8 00:00:18,079 --> 00:00:21,000 Speaker 1: He's a giant Pacific octopus who lives at an aquarium 9 00:00:21,000 --> 00:00:24,760 Speaker 1: in Cornwall, England. So he's this beautiful six ft wide 10 00:00:24,760 --> 00:00:28,000 Speaker 1: creature and he insists on cuddling with his Mr. Potato 11 00:00:28,040 --> 00:00:30,760 Speaker 1: Head toy, which sounds cute. It is, but Louis gets 12 00:00:30,800 --> 00:00:33,080 Speaker 1: really aggressive if you try to take it away from him, 13 00:00:33,080 --> 00:00:35,319 Speaker 1: so don't try to do that. I mean, Luis needs 14 00:00:35,360 --> 00:00:39,000 Speaker 1: to learn to share. So is he just rearranging the toy? Well, 15 00:00:39,000 --> 00:00:41,519 Speaker 1: he does fiddle with the parts and and supposedly the 16 00:00:41,560 --> 00:00:45,040 Speaker 1: bright colors are also stimulating. But the most appealing thing 17 00:00:45,120 --> 00:00:47,440 Speaker 1: for him is that the scientists fill the tiny toy 18 00:00:47,520 --> 00:00:50,199 Speaker 1: with crab meat or smelt. They just stuff it through 19 00:00:50,240 --> 00:00:52,640 Speaker 1: the arm and the headholes and it's a bit of 20 00:00:52,640 --> 00:00:54,960 Speaker 1: a puzzle. I mean, it's fun for Louis and other 21 00:00:54,960 --> 00:00:57,720 Speaker 1: octopus to figure out how to get those treats. But 22 00:00:57,840 --> 00:01:01,080 Speaker 1: reading about Louis made me wonder how smart are squid 23 00:01:01,080 --> 00:01:04,640 Speaker 1: and octopus? What are the major differences between them? And 24 00:01:04,680 --> 00:01:07,720 Speaker 1: how exactly do you stuff a smelt into a potato head? 25 00:01:08,280 --> 00:01:29,360 Speaker 1: And that's exactly what today's show is all about. It's 26 00:01:29,400 --> 00:01:31,360 Speaker 1: alp in to part time Genius. I'm Will Pearson and 27 00:01:31,360 --> 00:01:33,240 Speaker 1: as always I'm joined by my good friend Manuesh I 28 00:01:33,319 --> 00:01:36,440 Speaker 1: ticket off and sitting behind the soundproof glass wearing his 29 00:01:36,720 --> 00:01:39,399 Speaker 1: Octopus Give the Best Hugs t shirt is our friend 30 00:01:39,440 --> 00:01:42,440 Speaker 1: and producer Tristan McNeil. He'd been staring at that thing 31 00:01:42,480 --> 00:01:46,559 Speaker 1: on eBay for weeks. Tobago, Today's show is a little 32 00:01:46,640 --> 00:01:48,840 Speaker 1: all over the place. I know, we wanted to chat 33 00:01:48,880 --> 00:01:52,560 Speaker 1: about squid and octopus. Yeah, that's right, but since we're 34 00:01:52,600 --> 00:01:54,240 Speaker 1: covering the sea, I thought would be fun to slip 35 00:01:54,240 --> 00:01:56,200 Speaker 1: in a quick chat with one of our favorite authors, 36 00:01:56,440 --> 00:02:00,160 Speaker 1: Julie Burwald. She wrote this lovely new book called Spineless. 37 00:02:00,200 --> 00:02:03,280 Speaker 1: It's all about jellyfish and and though octopus and squid 38 00:02:03,400 --> 00:02:06,080 Speaker 1: and jellyfish aren't exactly the same thing, it did feel 39 00:02:06,080 --> 00:02:08,920 Speaker 1: like a delicious seafood salad of an episode. But you 40 00:02:08,919 --> 00:02:11,959 Speaker 1: don't even eat octopus, maga. I know, you know, I 41 00:02:12,120 --> 00:02:14,400 Speaker 1: actually used to eat it, But then we did this 42 00:02:14,520 --> 00:02:16,840 Speaker 1: article on octopus and metal flass and they just seemed 43 00:02:16,840 --> 00:02:21,160 Speaker 1: too smart. And also it compared the creatures two kittens. Actually, 44 00:02:21,200 --> 00:02:22,720 Speaker 1: I pulled up this quote because I thought it was 45 00:02:22,720 --> 00:02:26,000 Speaker 1: so funny. Here to the chagrin of some scientists, these 46 00:02:26,000 --> 00:02:29,920 Speaker 1: cephalopods can run. As a pre vet student, Alexa Warburton 47 00:02:30,040 --> 00:02:32,840 Speaker 1: had the tricky task of scooping octopuses out of their tanks. 48 00:02:33,160 --> 00:02:35,720 Speaker 1: The stubborn animals would hide or squeeze into the tanks 49 00:02:35,760 --> 00:02:39,120 Speaker 1: cracks to avoid being removed. As a last ditch effort, 50 00:02:39,400 --> 00:02:42,560 Speaker 1: some octopuses would trampoline off the net, leap to the floor, 51 00:02:42,600 --> 00:02:46,760 Speaker 1: and take off zig zagging around the lab. It's like quote, 52 00:02:46,960 --> 00:02:51,160 Speaker 1: chasing a cat, Warburton told a Ryan Magazine. Yeah, I mean, 53 00:02:51,160 --> 00:02:53,760 Speaker 1: I feel like hurting octopus is the new herding cats. 54 00:02:53,760 --> 00:02:55,720 Speaker 1: But that there was a been in the story where 55 00:02:55,720 --> 00:02:58,839 Speaker 1: this octopus actually escaped into a scientists library, and when 56 00:02:58,840 --> 00:03:01,239 Speaker 1: the scientist walked in, he saw the octopus going through 57 00:03:01,240 --> 00:03:03,840 Speaker 1: each of his books, just turning the page away. Is 58 00:03:03,880 --> 00:03:06,560 Speaker 1: that actually true? Yeah, we fact checked it. I mean, 59 00:03:06,600 --> 00:03:10,079 Speaker 1: there's certainly escape artists, and they're kind of destructive. To 60 00:03:10,680 --> 00:03:13,760 Speaker 1: Scientific American reporter that two workers at the Santa Monica 61 00:03:13,840 --> 00:03:17,240 Speaker 1: Pier Aquarium walked in to find two gallons of seawater 62 00:03:17,480 --> 00:03:20,440 Speaker 1: soaking the floor of their new space. They try to 63 00:03:20,480 --> 00:03:22,440 Speaker 1: figure out what had happened, and they realized these two 64 00:03:22,520 --> 00:03:27,240 Speaker 1: octopus had quote disassembled a water recycling valve and redirected 65 00:03:27,240 --> 00:03:29,480 Speaker 1: the two to spew water out of the tank for 66 00:03:29,560 --> 00:03:32,359 Speaker 1: about ten hours. There must have been so much water 67 00:03:32,680 --> 00:03:35,440 Speaker 1: it ridiculous. But I mean that seems more playful than 68 00:03:35,480 --> 00:03:38,600 Speaker 1: means spirited, right, And obviously we know that octopus is 69 00:03:38,640 --> 00:03:41,720 Speaker 1: play not just from your Lewis and Mr Potato Head example, 70 00:03:41,840 --> 00:03:45,320 Speaker 1: but also because octopuses have been observed in boring situations 71 00:03:45,320 --> 00:03:48,440 Speaker 1: amusing themselves. So there was this one story I read 72 00:03:48,440 --> 00:03:50,839 Speaker 1: where this octopus and a tank was given like an 73 00:03:50,840 --> 00:03:53,880 Speaker 1: empty floating pill bottle, I think, and after enough time 74 00:03:53,880 --> 00:03:55,960 Speaker 1: it started flicking it into a jet of water in 75 00:03:56,000 --> 00:03:58,480 Speaker 1: the aquarium and waiting for it to come back, then 76 00:03:58,520 --> 00:04:01,040 Speaker 1: doing it again and again in the scientists claimed it 77 00:04:01,080 --> 00:04:03,000 Speaker 1: was like watching a kid throw a ball against the wall, 78 00:04:03,120 --> 00:04:06,720 Speaker 1: but it did make me wonder how smarter octopus? And 79 00:04:06,760 --> 00:04:09,640 Speaker 1: so what did you find out? That octopus aren't really 80 00:04:09,760 --> 00:04:13,320 Speaker 1: very cooperative subjects? I mean, obviously they've got all these 81 00:04:13,320 --> 00:04:16,280 Speaker 1: skills right there, super strong, they can hide. Sometimes they 82 00:04:16,320 --> 00:04:19,640 Speaker 1: mimic other forms, and and you're talking specifically about the 83 00:04:19,680 --> 00:04:22,440 Speaker 1: mimic octopus. That's one of the types of octopus. Right. Yeah, 84 00:04:22,480 --> 00:04:25,440 Speaker 1: they're masters of disguise and changing their shapes, but they're 85 00:04:25,480 --> 00:04:28,159 Speaker 1: also good at going through mazes and solving little puzzles. 86 00:04:28,160 --> 00:04:31,000 Speaker 1: But all of that makes them really difficult to study. 87 00:04:31,080 --> 00:04:33,040 Speaker 1: So this is from a report I saw in the Guardian. 88 00:04:33,600 --> 00:04:37,520 Speaker 1: Apparently this paper tried to teach three octopus to pull 89 00:04:37,560 --> 00:04:40,240 Speaker 1: a lever for food. And we've seen this with you know, 90 00:04:40,360 --> 00:04:43,000 Speaker 1: monkeys and rats and other creatures. And first of all, 91 00:04:43,040 --> 00:04:46,159 Speaker 1: the octopus in the study have the best, most dignified names. 92 00:04:46,640 --> 00:04:50,200 Speaker 1: What's that They were called Albert, Bertram, and Charles. That's 93 00:04:50,240 --> 00:04:52,839 Speaker 1: what I would have named my octopus. That that is dignified. 94 00:04:53,240 --> 00:04:56,040 Speaker 1: So Albert and Bertram are really good subjects. They pulled 95 00:04:56,080 --> 00:04:59,320 Speaker 1: the levers in a quote reasonably consistent manner. According to 96 00:04:59,320 --> 00:05:02,839 Speaker 1: the study. It Charles, it turns out, is a total terror. 97 00:05:03,680 --> 00:05:05,640 Speaker 1: He tries to pull a light that's suspended above the 98 00:05:05,640 --> 00:05:08,480 Speaker 1: water into the tank. He squirts water at anyone who 99 00:05:08,560 --> 00:05:11,839 Speaker 1: gets close. He's basically taunting the scientists, and then he 100 00:05:11,960 --> 00:05:14,200 Speaker 1: ends the experiment by breaking off the levers so they 101 00:05:14,200 --> 00:05:18,239 Speaker 1: couldn't run the experiment anymore. I mean, Charles is totally gangster. 102 00:05:18,360 --> 00:05:19,720 Speaker 1: I mean, I have to admit I kind of like 103 00:05:19,839 --> 00:05:22,800 Speaker 1: Charles amusing to watch him. I feel like maybe there's 104 00:05:22,839 --> 00:05:26,039 Speaker 1: a whole episode to be done on octopus is behaving badly. 105 00:05:26,120 --> 00:05:29,039 Speaker 1: I mean they can undo latches and untied knots. I 106 00:05:29,080 --> 00:05:31,960 Speaker 1: even saw a story where scientists were complaining that octopus 107 00:05:31,960 --> 00:05:34,520 Speaker 1: would leave their lab tanks at night and then go 108 00:05:34,720 --> 00:05:38,320 Speaker 1: raid the neighboring tanks for food. There was one octopus 109 00:05:38,360 --> 00:05:40,600 Speaker 1: who was squirting water at the light switch to turn 110 00:05:40,640 --> 00:05:43,160 Speaker 1: it off, and then he short circuited the power. I mean, 111 00:05:43,320 --> 00:05:46,200 Speaker 1: these are these horror stories that come out, and clearly 112 00:05:46,200 --> 00:05:48,960 Speaker 1: they're kind of smart. But I wonder if we think 113 00:05:49,000 --> 00:05:51,960 Speaker 1: octopuses are especially smart because they look like, I don't know, 114 00:05:52,000 --> 00:05:54,840 Speaker 1: like aliens really, I mean they are alien like. I 115 00:05:54,880 --> 00:05:56,800 Speaker 1: don't think we'd be doing this episode if they weren't, 116 00:05:56,800 --> 00:06:00,480 Speaker 1: and their entire class of mollus is called sephalopods, which 117 00:06:00,520 --> 00:06:03,560 Speaker 1: means head foot. They're all a bunch of head feet. 118 00:06:04,920 --> 00:06:07,720 Speaker 1: And to be clear, that category isn't just octopus and 119 00:06:07,800 --> 00:06:11,479 Speaker 1: includes squid and cuttle fish and nautilus is But there's 120 00:06:11,520 --> 00:06:14,359 Speaker 1: a big debate about whether they're really that smart. The 121 00:06:14,440 --> 00:06:18,080 Speaker 1: octopus have about a half billion neurons, and that's particularly 122 00:06:18,120 --> 00:06:20,839 Speaker 1: amazing for a creature without a backbone. But you know, 123 00:06:20,880 --> 00:06:23,200 Speaker 1: in reality, it puts them in the range of dogs. 124 00:06:23,680 --> 00:06:25,839 Speaker 1: So even though they might play with a Rubik's cube, 125 00:06:25,839 --> 00:06:28,440 Speaker 1: but it's not like they're consistently solving them or anything, 126 00:06:28,440 --> 00:06:31,640 Speaker 1: at least I haven't seen one. There's this old Burden 127 00:06:31,680 --> 00:06:34,480 Speaker 1: Ernie sketch from Sesame Street where Ernie walks in on 128 00:06:34,640 --> 00:06:37,360 Speaker 1: Burt and he says, that's amazing, Butt, you're playing checkers 129 00:06:37,400 --> 00:06:40,960 Speaker 1: with your pigeon, and Bert kind of whispers something like, Ernie, 130 00:06:41,040 --> 00:06:43,320 Speaker 1: it's not that impressive. Of the seven times we've played, 131 00:06:43,320 --> 00:06:47,000 Speaker 1: he's only one twice. I think one thing I read 132 00:06:47,040 --> 00:06:49,360 Speaker 1: that really convinced me of their intelligence was that when 133 00:06:49,360 --> 00:06:52,240 Speaker 1: they're faced with the problem, they actually changed strategies. How 134 00:06:52,240 --> 00:06:55,480 Speaker 1: do you mean so scientific? American pointed this out, but 135 00:06:55,600 --> 00:06:59,360 Speaker 1: Apparently octopuses are a little lazy, Like, they're obviously quite strong, 136 00:06:59,480 --> 00:07:02,080 Speaker 1: and if they're given muscles or clams, they'll go for 137 00:07:02,120 --> 00:07:04,360 Speaker 1: the muscles just because the meat is easier to get 138 00:07:04,400 --> 00:07:06,760 Speaker 1: to and the shells take less effort. But if the 139 00:07:06,800 --> 00:07:08,680 Speaker 1: clams are served on a half shell, you know, if 140 00:07:08,680 --> 00:07:10,960 Speaker 1: they're at a cocktail party or something, they'll go for 141 00:07:11,000 --> 00:07:14,800 Speaker 1: the tastier meteor options. But here's what's interesting. Right when 142 00:07:14,840 --> 00:07:17,360 Speaker 1: scientists passed the long muscles, but whyed a few of 143 00:07:17,400 --> 00:07:20,000 Speaker 1: the shells shut? The octopus tried to open it using 144 00:07:20,040 --> 00:07:22,360 Speaker 1: one method They can use their arms, but then they 145 00:07:22,400 --> 00:07:24,400 Speaker 1: also have this beak that they can use to chip 146 00:07:24,400 --> 00:07:26,680 Speaker 1: away at the shell. And then when that took too long, 147 00:07:26,720 --> 00:07:29,160 Speaker 1: they drilled a little hole in and injected a poison 148 00:07:29,240 --> 00:07:32,800 Speaker 1: to weaken the creature's defenses. Like all octopus and cuttlefish 149 00:07:32,880 --> 00:07:35,520 Speaker 1: have a poison reserve. But the octopus would use one 150 00:07:35,560 --> 00:07:37,720 Speaker 1: method and if that proved futile, they switched to a 151 00:07:37,720 --> 00:07:40,440 Speaker 1: different one. And the author's point was most creatures, when 152 00:07:40,480 --> 00:07:42,160 Speaker 1: they fail, they just keep trying to do the same 153 00:07:42,200 --> 00:07:44,520 Speaker 1: thing over and over rather than adjust their approach. That 154 00:07:44,720 --> 00:07:46,480 Speaker 1: is pretty cool, and I know we're going to get 155 00:07:46,520 --> 00:07:49,400 Speaker 1: into the giant squid and cracking and how octopus and 156 00:07:49,400 --> 00:07:52,200 Speaker 1: squid are different. But before we do, let's chat a 157 00:07:52,240 --> 00:07:54,600 Speaker 1: little bit more about the octopus. So what's one of 158 00:07:54,600 --> 00:07:56,880 Speaker 1: the more surprising things you learned about them and doing 159 00:07:56,880 --> 00:08:00,800 Speaker 1: your research this week. Uh, that they're not good swimmers, 160 00:08:00,800 --> 00:08:03,320 Speaker 1: I think was interesting to me, and the reasons even weirder. 161 00:08:03,320 --> 00:08:05,840 Speaker 1: It's all because they have three hearts, So they're not 162 00:08:05,920 --> 00:08:08,640 Speaker 1: good swimmers because they have Yeah. Actually that was surprising 163 00:08:08,720 --> 00:08:10,559 Speaker 1: to me too. I mean I read in smith sony 164 00:08:10,640 --> 00:08:13,200 Speaker 1: and that two of the hearts worked to move blood 165 00:08:13,280 --> 00:08:16,240 Speaker 1: beyond their gills. And obviously there's so many parts of 166 00:08:16,240 --> 00:08:20,000 Speaker 1: the octopus I didn't realize beaks and gills and ragul 167 00:08:20,200 --> 00:08:22,760 Speaker 1: which is kind of like a tiny drill for a tongue. Yeah, 168 00:08:22,800 --> 00:08:24,760 Speaker 1: and their penis is on one of their arms, which 169 00:08:24,760 --> 00:08:26,960 Speaker 1: I also never realized. I mean, I guess that's a 170 00:08:26,960 --> 00:08:30,880 Speaker 1: little weird too. You know that while some octopus mount 171 00:08:30,920 --> 00:08:33,640 Speaker 1: their partners, others will just stick their penis arm into 172 00:08:33,679 --> 00:08:36,720 Speaker 1: a cave where a female octopus is hiding, and so 173 00:08:36,760 --> 00:08:40,480 Speaker 1: they made in what's called the distance position. That's so ridiculous. 174 00:08:40,840 --> 00:08:43,320 Speaker 1: But we were talking about the three hearts. All right, 175 00:08:43,360 --> 00:08:46,360 Speaker 1: So the two hearts move blood beyond the gills, and 176 00:08:46,400 --> 00:08:50,199 Speaker 1: then the third heart is exclusively for pumping blood to organs. 177 00:08:50,760 --> 00:08:53,680 Speaker 1: But when they're swimming, they actually turned that heart off. 178 00:08:53,960 --> 00:08:57,560 Speaker 1: It stops beating entirely. So they get completely exhausted when 179 00:08:57,600 --> 00:09:00,440 Speaker 1: they move that way, and they mostly choose a walk 180 00:09:00,520 --> 00:09:03,360 Speaker 1: or crawl instead. But I like the idea that octopuses 181 00:09:03,360 --> 00:09:06,400 Speaker 1: actually enjoy long walks on the beach. But there's clearly 182 00:09:06,440 --> 00:09:09,280 Speaker 1: a ton more to say about these bizarre and wonderful creatures. 183 00:09:09,320 --> 00:09:10,840 Speaker 1: But I also want to get Julie on the phone 184 00:09:10,840 --> 00:09:13,000 Speaker 1: to talk about jellyfish. So how about we take a 185 00:09:13,000 --> 00:09:14,600 Speaker 1: little break for that and then we dive back in. 186 00:09:14,760 --> 00:09:22,680 Speaker 1: All right, let's do it, Mango. We've got a special 187 00:09:22,679 --> 00:09:24,640 Speaker 1: guest on the line with us today. She's the author 188 00:09:24,640 --> 00:09:27,600 Speaker 1: of a fascinating new book called Spineless, The Science of 189 00:09:27,679 --> 00:09:31,360 Speaker 1: Jellyfish and the Art of Growing a Backbone. Julie Berwald. 190 00:09:31,400 --> 00:09:33,679 Speaker 1: Welcome to part time Genius. Thank you so much for 191 00:09:33,720 --> 00:09:37,280 Speaker 1: having me so, Julie. Jellyfish are obviously these simple and 192 00:09:37,360 --> 00:09:41,240 Speaker 1: beautiful but also reviled creatures, and they cause problems for 193 00:09:41,280 --> 00:09:44,240 Speaker 1: swimmers and factories. I'm kind of curious why did you 194 00:09:44,360 --> 00:09:47,360 Speaker 1: choose to study the jellyfish. Yeah, I mean it's true, 195 00:09:47,520 --> 00:09:50,360 Speaker 1: and and there's something about what you just said that 196 00:09:50,559 --> 00:09:54,480 Speaker 1: made them really fascinating to me, because, um, you know, 197 00:09:54,480 --> 00:09:57,240 Speaker 1: you couldn't put polar bears in this like box of like, oh, 198 00:09:57,280 --> 00:10:02,320 Speaker 1: they're so you know, impress sieve and and beautiful and 199 00:10:02,640 --> 00:10:06,960 Speaker 1: big and they they are this charismatic creature and but 200 00:10:07,080 --> 00:10:12,319 Speaker 1: jellys have more subtlety to them. You know, they're undeniably beautiful, 201 00:10:12,880 --> 00:10:15,240 Speaker 1: and yet you're right, like they can be lethal and 202 00:10:15,280 --> 00:10:19,560 Speaker 1: they can be as you know, a symbol of ecosystem demise. 203 00:10:20,280 --> 00:10:22,560 Speaker 1: And there was something about that, the fact that they 204 00:10:22,679 --> 00:10:25,320 Speaker 1: kind of walked it back and forth across these lines 205 00:10:25,480 --> 00:10:30,000 Speaker 1: in our minds that I found super fascinating. And they're 206 00:10:30,040 --> 00:10:32,280 Speaker 1: just such strange creatures too. I know you've written that 207 00:10:32,320 --> 00:10:34,520 Speaker 1: they can see light without eyes. Do you do you 208 00:10:34,520 --> 00:10:37,000 Speaker 1: mind just taking a minute for our listeners and describe 209 00:10:37,040 --> 00:10:39,120 Speaker 1: a little bit of their biology and and and what 210 00:10:39,240 --> 00:10:41,600 Speaker 1: some of the more curious things about their bodies that 211 00:10:41,640 --> 00:10:45,160 Speaker 1: you've found. Um, yeah, so you know, they are super simple. 212 00:10:45,240 --> 00:10:48,760 Speaker 1: They have just like we have three cell layers that 213 00:10:48,840 --> 00:10:51,640 Speaker 1: we have an end their deerm and exoderm, which is 214 00:10:51,679 --> 00:10:54,080 Speaker 1: like our skin, our outside skin, and then in between 215 00:10:54,120 --> 00:10:56,559 Speaker 1: we have this musoderm that holds all our organs and everything, 216 00:10:56,880 --> 00:10:59,560 Speaker 1: and jelly fish just don't have that. They have jelly inside. 217 00:10:59,720 --> 00:11:04,160 Speaker 1: It's truly it's called mesoglia, and it's a cellular and 218 00:11:04,200 --> 00:11:10,400 Speaker 1: so um they have this really cool ability that they 219 00:11:10,480 --> 00:11:14,160 Speaker 1: they're like big. They're like a balloon, right, So they 220 00:11:14,160 --> 00:11:16,280 Speaker 1: have skin on the outside, skin on the inside, and 221 00:11:16,320 --> 00:11:19,720 Speaker 1: then something that they don't have to support metabolically on 222 00:11:19,760 --> 00:11:22,880 Speaker 1: the inside. So they get away with being big at 223 00:11:23,040 --> 00:11:26,600 Speaker 1: very low metabolic cost. And that's part of what makes 224 00:11:26,640 --> 00:11:30,280 Speaker 1: them so successful. And that's why I called the book Spineless, 225 00:11:30,320 --> 00:11:34,040 Speaker 1: because they're very spinelessness is actually contributing to their um 226 00:11:34,360 --> 00:11:38,520 Speaker 1: increase in abundances in many places in our oceans. I 227 00:11:38,559 --> 00:11:42,120 Speaker 1: went to go visit these um scientists in Woodhole who 228 00:11:42,120 --> 00:11:44,800 Speaker 1: work at the Marine Biological Laboratory there, and they were 229 00:11:45,240 --> 00:11:48,760 Speaker 1: the Navy had given them money to build robotic jellyfish, 230 00:11:48,960 --> 00:11:52,440 Speaker 1: and they weren't entirely certain what the Navy wanted to 231 00:11:52,440 --> 00:11:54,680 Speaker 1: do with these robotic jelly miss that they were pretty 232 00:11:54,679 --> 00:11:58,320 Speaker 1: excited about the opportunity, and so they created this jellyfish 233 00:11:58,800 --> 00:12:02,599 Speaker 1: out of silicone and sort of like fake muscles called actuators. 234 00:12:02,640 --> 00:12:05,480 Speaker 1: And when they turned it on um it squeezed and 235 00:12:05,720 --> 00:12:07,840 Speaker 1: it squeezed shut, and that causes a jet of water 236 00:12:07,920 --> 00:12:10,360 Speaker 1: to come out behind it, which pushes on the water 237 00:12:10,440 --> 00:12:12,720 Speaker 1: and it moves the jellyfish forward. But then when it 238 00:12:12,800 --> 00:12:15,440 Speaker 1: opened back up, it went right back to its starting 239 00:12:15,480 --> 00:12:17,640 Speaker 1: place like a yo yo. And they were like, oh, 240 00:12:17,720 --> 00:12:21,720 Speaker 1: what's going on, And so they this graduate student was like, well, 241 00:12:22,559 --> 00:12:24,920 Speaker 1: you know that peplum around the edge of the jellyfish, 242 00:12:24,920 --> 00:12:28,439 Speaker 1: that part that's kind of beautiful that just flops around. 243 00:12:28,080 --> 00:12:30,520 Speaker 1: The graduate student was like, I didn't have time to 244 00:12:30,600 --> 00:12:33,720 Speaker 1: glue that little flap on the robot. So they pulled 245 00:12:33,760 --> 00:12:35,440 Speaker 1: it out of the water and they glued it on. 246 00:12:35,520 --> 00:12:37,559 Speaker 1: They put it back in the water, and they turned 247 00:12:37,600 --> 00:12:41,160 Speaker 1: it on and it's it's They turned it on and 248 00:12:41,160 --> 00:12:43,200 Speaker 1: it squeezed and it jetted forward, and then when it 249 00:12:43,280 --> 00:12:46,559 Speaker 1: opened up, it actually continued going forward. And then it 250 00:12:46,600 --> 00:12:48,760 Speaker 1: squeezed again and it went forward farther, and then it 251 00:12:48,800 --> 00:12:50,959 Speaker 1: opened and it continued going forward. And it turns out 252 00:12:51,000 --> 00:12:55,640 Speaker 1: that that little flexible flap is is what drives part 253 00:12:55,679 --> 00:12:58,160 Speaker 1: of what drives the jellyfish forward. In the water. It 254 00:12:58,280 --> 00:13:03,000 Speaker 1: gives it the push backwards. But then they figured out, um, 255 00:13:03,040 --> 00:13:05,640 Speaker 1: it doesn't only give it a push backwards, it actually 256 00:13:05,679 --> 00:13:09,600 Speaker 1: creates a low pressure zone in front of the jellyfish. 257 00:13:09,679 --> 00:13:13,240 Speaker 1: Like the bending kind of creates the suction in front 258 00:13:13,240 --> 00:13:17,360 Speaker 1: of the jellyfish, and that suction pulls the animal forward 259 00:13:17,400 --> 00:13:19,880 Speaker 1: through the water. And then they started looking at all 260 00:13:19,920 --> 00:13:23,199 Speaker 1: these other animals and if you think about it, everything 261 00:13:23,240 --> 00:13:26,760 Speaker 1: in the ocean or in water, then when it moves 262 00:13:26,840 --> 00:13:29,640 Speaker 1: like nothing solid, like the way we build both they 263 00:13:29,640 --> 00:13:32,560 Speaker 1: all bend. And the reason for that bending is because 264 00:13:33,200 --> 00:13:35,320 Speaker 1: it creates this low pressure in front of the animal 265 00:13:35,360 --> 00:13:37,640 Speaker 1: that pulls it through the water. So we've thought about, 266 00:13:38,440 --> 00:13:42,960 Speaker 1: um swimming completely backwards. It turns out that um, the 267 00:13:43,040 --> 00:13:45,800 Speaker 1: forces you know in front of the jelly fish pulling 268 00:13:45,840 --> 00:13:49,000 Speaker 1: it are stronger than the forces behind the jellyfish pushing it. 269 00:13:49,400 --> 00:13:52,320 Speaker 1: And because we're terrestrial and all we can do is 270 00:13:52,320 --> 00:13:56,240 Speaker 1: push backwards in order to go forwards, we just completely 271 00:13:56,640 --> 00:14:00,720 Speaker 1: misunderstood swimming for our whole all of subtle antion really 272 00:14:01,600 --> 00:14:05,240 Speaker 1: and then, um, yeah, it's a really cool story. All right. Well, 273 00:14:05,240 --> 00:14:07,120 Speaker 1: speaking of travel, I know you traveled all the way 274 00:14:07,160 --> 00:14:10,120 Speaker 1: to Japan to see the giant jellyfish there, So so 275 00:14:10,160 --> 00:14:12,560 Speaker 1: what makes it so extraordinary and why did you make 276 00:14:12,600 --> 00:14:15,520 Speaker 1: the trip there to see it? Yeah, this jelly fish 277 00:14:15,559 --> 00:14:20,320 Speaker 1: is really really interesting. Um it grows to being five pound, 278 00:14:20,480 --> 00:14:23,920 Speaker 1: which is like the size of a refrigerator. Yeah, it's massive, 279 00:14:24,200 --> 00:14:28,720 Speaker 1: massive jelly fish, you know. And throughout the twentieth century, 280 00:14:28,880 --> 00:14:32,560 Speaker 1: this jellyfish was seen in just off the coast of Japan, 281 00:14:32,680 --> 00:14:35,840 Speaker 1: but only about every thirty years. So because the kind 282 00:14:35,840 --> 00:14:38,320 Speaker 1: of thing where like a fisherman would tell his son like, 283 00:14:38,880 --> 00:14:41,480 Speaker 1: well that you're the giant jellyfish showed up, you know, 284 00:14:41,720 --> 00:14:43,960 Speaker 1: look out for them, and then thirty years later the 285 00:14:44,000 --> 00:14:45,680 Speaker 1: sun would be like, oh, yeah, this is what my 286 00:14:45,720 --> 00:14:49,000 Speaker 1: dad told me about. And then in the twenty one 287 00:14:49,080 --> 00:14:54,320 Speaker 1: century they started appearing every year, and not just every year, 288 00:14:54,400 --> 00:14:58,880 Speaker 1: but like in enormous numbers, where the entire cy would 289 00:14:58,880 --> 00:15:02,480 Speaker 1: be just these huge and they're sort of maroon, these 290 00:15:02,520 --> 00:15:06,000 Speaker 1: maroon giant blobs of jellyfish for as far as the 291 00:15:06,040 --> 00:15:10,080 Speaker 1: eye could see. And there's pictures of fishing boats with 292 00:15:10,200 --> 00:15:14,960 Speaker 1: their nets just the sea of maroon jelly. One fishing 293 00:15:15,040 --> 00:15:17,560 Speaker 1: vessel collected so many of these giant jellyfish that it 294 00:15:17,640 --> 00:15:20,120 Speaker 1: actually the weight of them in their nets, flips the 295 00:15:20,160 --> 00:15:24,520 Speaker 1: boat over and threw the crew into the sea. And 296 00:15:24,720 --> 00:15:26,920 Speaker 1: I just want to ask very quickly. You know, for 297 00:15:27,000 --> 00:15:28,840 Speaker 1: years people have been saying that jellyfish are gonna be 298 00:15:28,880 --> 00:15:32,200 Speaker 1: winners in this world of climate change. But why is 299 00:15:32,200 --> 00:15:34,960 Speaker 1: it important that we have a balanced population of jellyfish? 300 00:15:35,400 --> 00:15:38,600 Speaker 1: The questions look really complex, and I think that we 301 00:15:38,640 --> 00:15:41,400 Speaker 1: have a tendency to look at the ocean is like 302 00:15:41,440 --> 00:15:44,520 Speaker 1: this one big place, and in fact, you know, the 303 00:15:44,560 --> 00:15:48,600 Speaker 1: ocean is a really uh diverse, dynamic place that has 304 00:15:48,680 --> 00:15:53,320 Speaker 1: lots of different ecosystems, lots of latitudes and longitudes, different temperatures, 305 00:15:53,320 --> 00:15:57,440 Speaker 1: different salinities and so and different kinds of pressures that 306 00:15:57,480 --> 00:16:00,200 Speaker 1: we're putting on the ocean. So in some places is 307 00:16:00,320 --> 00:16:04,000 Speaker 1: already jellyfish are dominating the ecosystem. And those are the 308 00:16:04,000 --> 00:16:06,600 Speaker 1: places that we should look to to say, like do 309 00:16:06,600 --> 00:16:09,320 Speaker 1: we want our oceans in other places to become like that? 310 00:16:10,040 --> 00:16:12,680 Speaker 1: And Um, a good example is off the coast in 311 00:16:12,760 --> 00:16:16,960 Speaker 1: Namibia where they really really over fished the ocean. Um, 312 00:16:17,120 --> 00:16:19,760 Speaker 1: there was not good controls on what was happening. In fact, 313 00:16:19,920 --> 00:16:23,040 Speaker 1: Numidia was under the offices of South Africa for a 314 00:16:23,080 --> 00:16:25,880 Speaker 1: long time and South Africa didn't monitor what was happening 315 00:16:25,880 --> 00:16:28,440 Speaker 1: in Nimidia, and these big commercial ships came in from 316 00:16:28,520 --> 00:16:32,840 Speaker 1: other countries and just fished it like crazy and opened 317 00:16:32,920 --> 00:16:37,920 Speaker 1: up ecological niches for jellyfish. And it used to be 318 00:16:37,960 --> 00:16:40,160 Speaker 1: one of the richest fisheries in the world, where like 319 00:16:40,840 --> 00:16:43,840 Speaker 1: a million tons of fish every year could be fished easily, 320 00:16:44,640 --> 00:16:48,200 Speaker 1: and then the jellyfish we're able to get a foothold, 321 00:16:48,440 --> 00:16:51,360 Speaker 1: and now the biomass is like two to three times 322 00:16:51,360 --> 00:16:54,880 Speaker 1: more jellyfish than fish there, and the seals and birds 323 00:16:55,000 --> 00:16:57,440 Speaker 1: there's reports of them starving because there's just not enough 324 00:16:57,440 --> 00:17:00,640 Speaker 1: fish for them to eat anymore. So the reason why 325 00:17:00,720 --> 00:17:03,440 Speaker 1: we want to pay attention to this is because we 326 00:17:03,440 --> 00:17:06,560 Speaker 1: could end up with ecosystems where birds and fields are starving, 327 00:17:06,600 --> 00:17:09,840 Speaker 1: and I don't think anyone wants that kind of situation. 328 00:17:10,119 --> 00:17:14,120 Speaker 1: Big bloom fish jellyfish can also sweep into fish farm 329 00:17:14,160 --> 00:17:16,920 Speaker 1: and about a month ago a huge bloom swept into 330 00:17:16,920 --> 00:17:19,560 Speaker 1: a fish farm in Scotland and killed like a quarter 331 00:17:19,680 --> 00:17:24,920 Speaker 1: or a a million famine overnight. So the yeah, the numbers, 332 00:17:25,000 --> 00:17:28,159 Speaker 1: you know, start to add up of the devastation that 333 00:17:28,240 --> 00:17:31,919 Speaker 1: jellyfish can cause. Not to mention the sting, the stings 334 00:17:31,960 --> 00:17:37,320 Speaker 1: that you know heard us very personally and individually in 335 00:17:37,359 --> 00:17:40,919 Speaker 1: the water and emotionally and and all of that. And 336 00:17:41,000 --> 00:17:43,840 Speaker 1: our our friend John would have very much appreciated you 337 00:17:43,920 --> 00:17:46,280 Speaker 1: having been there to educate him before he jumped in 338 00:17:46,320 --> 00:17:48,040 Speaker 1: the water. Do you remember this mango when we were 339 00:17:48,080 --> 00:17:50,560 Speaker 1: on a trip and the and the keys and he 340 00:17:50,880 --> 00:17:52,400 Speaker 1: we were out in a boat and he looks out 341 00:17:52,440 --> 00:17:53,880 Speaker 1: and he says, I don't think those are the kind 342 00:17:53,880 --> 00:17:56,560 Speaker 1: of jellyfish that staying. And there was a large school 343 00:17:56,560 --> 00:17:58,560 Speaker 1: of them, I guess, and he jumped in the water. 344 00:17:58,640 --> 00:18:00,400 Speaker 1: He says, these are the kind of thing, the kind 345 00:18:00,400 --> 00:18:04,720 Speaker 1: of thing. So it did not it did not go well. 346 00:18:04,840 --> 00:18:07,160 Speaker 1: So mainly this episode is to try to get him 347 00:18:07,160 --> 00:18:08,919 Speaker 1: to learn a little bit more and not make the 348 00:18:08,960 --> 00:18:11,919 Speaker 1: same mistake. So if you get stung by a jellyfish, 349 00:18:12,480 --> 00:18:16,240 Speaker 1: the thing you ushould do is hot water and vinegar. Julie, 350 00:18:16,280 --> 00:18:19,000 Speaker 1: this is such a wonderful read. The book is called Spineless, 351 00:18:19,000 --> 00:18:22,199 Speaker 1: The Science of Jellyfish in the Art of Growing Up Backbone. Julie, 352 00:18:22,200 --> 00:18:24,200 Speaker 1: thanks so much for joining us on Part Time Genius. 353 00:18:37,520 --> 00:18:40,760 Speaker 1: Welcome back to Part Time Genius. We're talking squid, octopus 354 00:18:40,840 --> 00:18:44,200 Speaker 1: and jellyfish. So we've been chatting octopuses for a while 355 00:18:44,359 --> 00:18:46,359 Speaker 1: and we need to move on to squid. But before 356 00:18:46,400 --> 00:18:48,520 Speaker 1: we do, why don't we reel off some of our 357 00:18:48,680 --> 00:18:51,800 Speaker 1: favorite octopus Definitely? What are some of the weirder ones 358 00:18:51,840 --> 00:18:53,879 Speaker 1: you want to talk about? Well, I love Louis. You 359 00:18:53,920 --> 00:18:57,280 Speaker 1: know the cantankerous giant pacific octopus we were talking about 360 00:18:57,800 --> 00:19:00,560 Speaker 1: also from that article. He was only ex feet but 361 00:19:00,560 --> 00:19:03,439 Speaker 1: they can actually grow to be about sixteen ft and 362 00:19:03,480 --> 00:19:07,080 Speaker 1: way up to six hundred pounds. Wow. Each arm has 363 00:19:07,400 --> 00:19:10,280 Speaker 1: about two hundred and eighty suckers and they lay up 364 00:19:10,320 --> 00:19:14,520 Speaker 1: to ninety thousand eggs at a time. Nine eggs, I know, 365 00:19:14,680 --> 00:19:18,080 Speaker 1: that's a lot of omelets. Well, one octopus I like, 366 00:19:18,119 --> 00:19:19,639 Speaker 1: on the other end of the spectrum is this thing 367 00:19:19,680 --> 00:19:23,160 Speaker 1: called the octopus wolfe, which is the world's smallest octopus. 368 00:19:23,560 --> 00:19:26,280 Speaker 1: It's like an inch long and ways less than a graham. Yeah. 369 00:19:26,440 --> 00:19:28,119 Speaker 1: I guess kind of like kind of like a pocket 370 00:19:28,119 --> 00:19:32,480 Speaker 1: octopus exactly, and it's perfect for travel. But that doesn't 371 00:19:32,480 --> 00:19:35,480 Speaker 1: mean they're not wildy. So, according to a Newsweek article, 372 00:19:35,600 --> 00:19:38,120 Speaker 1: a two thousand four study gave them a six out 373 00:19:38,119 --> 00:19:41,280 Speaker 1: of ten on likelihood of escaping a tank. All right, Well, 374 00:19:41,320 --> 00:19:44,040 Speaker 1: speaking of tiny octopus, this one's totally weird. It's called 375 00:19:44,080 --> 00:19:47,240 Speaker 1: the blanket octopus. And while the females are a tall 376 00:19:47,359 --> 00:19:50,840 Speaker 1: and leggy six ft long, the males are only about 377 00:19:50,880 --> 00:19:53,960 Speaker 1: an inch tall. How crazy is that? How's that possible? 378 00:19:54,080 --> 00:19:57,200 Speaker 1: I have no idea. But their mating technique is equally weird. 379 00:19:57,240 --> 00:20:00,520 Speaker 1: So here's how Newsweek described it. To breathe, the male 380 00:20:00,600 --> 00:20:04,240 Speaker 1: sticks his specialized mating arm inside the female and breaks 381 00:20:04,240 --> 00:20:07,200 Speaker 1: it off. He then swims away with only seven legs 382 00:20:07,240 --> 00:20:12,000 Speaker 1: and dies shortly after octopus romance. But the creatures are 383 00:20:12,040 --> 00:20:15,959 Speaker 1: even more interesting than that. Actually, well, the female blanket 384 00:20:15,960 --> 00:20:18,800 Speaker 1: octopus is is more of a swimmer, so instead of 385 00:20:18,840 --> 00:20:21,680 Speaker 1: hiding in caves, will actually swim in the open water, which, 386 00:20:21,720 --> 00:20:24,640 Speaker 1: as we've talked about, it is pretty unusual for an octopus. 387 00:20:24,760 --> 00:20:27,440 Speaker 1: And it fans out like a giant blanket whenever it 388 00:20:27,560 --> 00:20:30,520 Speaker 1: senses a threat. But it's the tiny male that's the 389 00:20:30,560 --> 00:20:33,840 Speaker 1: real character. So blanket octopuses are immune to man of 390 00:20:33,840 --> 00:20:37,160 Speaker 1: wars things, so when something is attacking a blanket male, 391 00:20:37,680 --> 00:20:40,280 Speaker 1: it'll just break off a poisonous tentacle of a Portuguese 392 00:20:40,359 --> 00:20:42,720 Speaker 1: man of war and then whip it around like crazy, 393 00:20:42,760 --> 00:20:45,280 Speaker 1: you know, the swashbuckle against its enemies. It's I mean, 394 00:20:45,320 --> 00:20:48,439 Speaker 1: they're pretty feisty. Actually, well, I do want to come 395 00:20:48,440 --> 00:20:51,359 Speaker 1: back to octopuses food and this whole etiquette of throwing 396 00:20:51,400 --> 00:20:54,600 Speaker 1: them at red wings games, because there's some strict rules there. 397 00:20:54,880 --> 00:20:56,960 Speaker 1: But let's get in the squid. So what are some 398 00:20:57,000 --> 00:21:01,000 Speaker 1: of the characteristics of squid. So here, the basic squids 399 00:21:01,040 --> 00:21:03,240 Speaker 1: are really good hunters. First of all, I mean, much 400 00:21:03,280 --> 00:21:06,560 Speaker 1: like octopus, they've got beaks and radula, so they have 401 00:21:06,720 --> 00:21:09,920 Speaker 1: ten arms in total. They actually have eight short arms 402 00:21:09,920 --> 00:21:13,160 Speaker 1: around the mouth and then these two long tentacles with suckers, 403 00:21:13,200 --> 00:21:17,000 Speaker 1: which are really helpful when they're hunting. Now, unlike octopus, 404 00:21:17,000 --> 00:21:20,440 Speaker 1: squids swim in the open ocean, and they're amazing swimmers. 405 00:21:20,760 --> 00:21:22,800 Speaker 1: In fact, they've been called the fighter jets of the 406 00:21:22,840 --> 00:21:26,760 Speaker 1: cephalopod because they use this water propulsion system to shoot 407 00:21:26,800 --> 00:21:30,359 Speaker 1: backwards at these tremendous speeds. Yeah, I've seen that some 408 00:21:30,400 --> 00:21:33,400 Speaker 1: consuming speeds of like twenty five miles per hour, which 409 00:21:33,400 --> 00:21:36,240 Speaker 1: is stunning because that's almost shark speeds. And I was 410 00:21:36,240 --> 00:21:39,480 Speaker 1: actually reading about Japanese flying squid. Have you heard of them? 411 00:21:39,520 --> 00:21:41,800 Speaker 1: I didn't realize the flying squid word thing. I don't know. 412 00:21:41,880 --> 00:21:44,000 Speaker 1: I missed that. Yeah, so they get confused for flying 413 00:21:44,040 --> 00:21:46,639 Speaker 1: fish sometimes, although flying fish can move that way for 414 00:21:46,680 --> 00:21:49,560 Speaker 1: great lens. Well, you know, these squid can only jump 415 00:21:49,600 --> 00:21:51,680 Speaker 1: out of the water for twenty stretches then they kind 416 00:21:51,680 --> 00:21:54,000 Speaker 1: of tire out. It seems more like a cool party 417 00:21:54,040 --> 00:21:57,200 Speaker 1: trick than anything that's wise in terms of evolution. So 418 00:21:57,320 --> 00:22:00,639 Speaker 1: why do you say that, Well, they accidentally jump onto 419 00:22:00,640 --> 00:22:03,520 Speaker 1: fishing boats all the time, and birds like the red 420 00:22:03,560 --> 00:22:05,680 Speaker 1: footed booby will just pluck them out of the air 421 00:22:05,720 --> 00:22:08,359 Speaker 1: for meals. You know, it's kind of a weird question. 422 00:22:08,400 --> 00:22:11,000 Speaker 1: But how do they see when they're flying backwards? Is 423 00:22:11,280 --> 00:22:12,879 Speaker 1: that why they end up on the boats because they 424 00:22:12,880 --> 00:22:14,800 Speaker 1: can't see where they're going or what? I think it's 425 00:22:14,840 --> 00:22:17,520 Speaker 1: more that they can't exactly like switch directions while they're 426 00:22:17,560 --> 00:22:20,600 Speaker 1: in the air. But from what I read, their eyes, tentacles, 427 00:22:20,600 --> 00:22:23,080 Speaker 1: and beak are all at the back, and as they're flying, 428 00:22:23,119 --> 00:22:25,440 Speaker 1: they have a pretty good view and they'll actually pull 429 00:22:25,480 --> 00:22:27,800 Speaker 1: their fins and adjust their tentacles to make a smoother 430 00:22:27,880 --> 00:22:30,359 Speaker 1: dive back into the water. There's still a lot of 431 00:22:30,359 --> 00:22:32,400 Speaker 1: study that has to be done on them, and that's 432 00:22:32,400 --> 00:22:34,400 Speaker 1: actually something that seems to come up a lot, Like 433 00:22:34,800 --> 00:22:37,040 Speaker 1: I read that one of the ways people catch octopus 434 00:22:37,080 --> 00:22:38,960 Speaker 1: is that they just place a little basket next to 435 00:22:39,000 --> 00:22:41,919 Speaker 1: an octopus cave or dwelling, and then octopus might just 436 00:22:41,960 --> 00:22:44,600 Speaker 1: snuggle into the basket and then fishermen can pull that up. 437 00:22:45,000 --> 00:22:48,120 Speaker 1: But catching enormous squid isn't that easy. And clearly there's 438 00:22:48,119 --> 00:22:51,640 Speaker 1: a fascination with the giant squid, which has been pretty elusive. Yeah, 439 00:22:51,680 --> 00:22:54,120 Speaker 1: it's funny to think about how that misunderstanding about giant 440 00:22:54,200 --> 00:22:56,760 Speaker 1: squid and just not being able to observe their behavior. 441 00:22:57,240 --> 00:22:59,360 Speaker 1: It's kind of made them these monsters of the sea. 442 00:22:59,359 --> 00:23:01,800 Speaker 1: I mean, you see their written about in literature and 443 00:23:01,880 --> 00:23:04,159 Speaker 1: Jules Verne's twenty thou Leagues under the Sea. You know, 444 00:23:04,160 --> 00:23:07,200 Speaker 1: it's this monstrous squid with a taste for human flesh 445 00:23:07,240 --> 00:23:10,600 Speaker 1: and attacks the submarine and everything. And he Actually I 446 00:23:10,640 --> 00:23:13,119 Speaker 1: was reading this article about the cracking and wired it 447 00:23:13,160 --> 00:23:16,439 Speaker 1: was called fantastically wrong and I didn't realize this, but 448 00:23:16,520 --> 00:23:20,119 Speaker 1: early Europeans assumed that all creatures on Earth had a 449 00:23:20,200 --> 00:23:23,399 Speaker 1: counterpart in the sea. So there were these strange beasts 450 00:23:23,400 --> 00:23:26,639 Speaker 1: like sea rhinos and even things like see bishops. You know, 451 00:23:26,680 --> 00:23:29,760 Speaker 1: the seafaring counterparts to the human land bishops. But the 452 00:23:29,800 --> 00:23:32,720 Speaker 1: descriptions of the crack and it's just crazy. So this 453 00:23:32,760 --> 00:23:37,040 Speaker 1: is from seventeen seventy five when an historian named Eric Pontpain. 454 00:23:37,520 --> 00:23:40,760 Speaker 1: He wrote in the Natural History of Norway, the beast 455 00:23:40,880 --> 00:23:43,919 Speaker 1: is round, flat and full of arms, the largest and 456 00:23:44,000 --> 00:23:47,600 Speaker 1: most surprising of all animal creations. He then claimed to 457 00:23:47,640 --> 00:23:50,000 Speaker 1: have talked to a number of different fishermen and all 458 00:23:50,040 --> 00:23:52,639 Speaker 1: of them gave the exact same description, including that the 459 00:23:52,680 --> 00:23:56,240 Speaker 1: squid's back is a mile and a half in circumference, 460 00:23:56,800 --> 00:24:00,040 Speaker 1: the various tentacles could be mistaken for islands. And the 461 00:24:00,160 --> 00:24:02,720 Speaker 1: funny thing is that there's this second mythical sea creatures 462 00:24:02,720 --> 00:24:05,680 Speaker 1: that gets described, and it says, um, the island whale 463 00:24:05,720 --> 00:24:09,720 Speaker 1: that's so big, sailors mistake it for land, And when 464 00:24:09,760 --> 00:24:12,360 Speaker 1: the sailors set shore and build fire on it, that's 465 00:24:12,400 --> 00:24:15,119 Speaker 1: when the beast awakens and drags them to their doom. 466 00:24:15,600 --> 00:24:17,800 Speaker 1: So most people assume that the crack and descriptions are 467 00:24:17,840 --> 00:24:21,600 Speaker 1: exaggerations of the giant squid that some fishermen must have seen, 468 00:24:22,080 --> 00:24:24,920 Speaker 1: which can be at least forty three ft long, which 469 00:24:24,960 --> 00:24:28,760 Speaker 1: is huge. Those the article reveals both the colossal squid 470 00:24:28,960 --> 00:24:32,320 Speaker 1: and the giant squid are you know, very lackadaisical and 471 00:24:32,359 --> 00:24:35,000 Speaker 1: by one estimate, use up to six hundred times less 472 00:24:35,080 --> 00:24:39,160 Speaker 1: energy than similarly sized predators. So supposedly they just hang 473 00:24:39,200 --> 00:24:42,600 Speaker 1: out waiting for prey instead of actively chasing anything. And 474 00:24:42,640 --> 00:24:45,640 Speaker 1: what's the difference between the colossal and giant squid. Well, 475 00:24:45,680 --> 00:24:48,640 Speaker 1: it's likely that the giant squid is longer than the colossal, 476 00:24:48,760 --> 00:24:52,479 Speaker 1: but the colossal is probably heavier and has bigger eyes. 477 00:24:53,040 --> 00:24:55,720 Speaker 1: And so giant squids also have teeth on their tentacles, 478 00:24:55,720 --> 00:24:59,119 Speaker 1: which of course is terrifying to think about, while colossal 479 00:24:59,160 --> 00:25:02,160 Speaker 1: squids have show art pokes that swivel on their tentacles. 480 00:25:02,160 --> 00:25:04,159 Speaker 1: So I mean, I guess it's just like a different 481 00:25:04,240 --> 00:25:07,200 Speaker 1: sort of terrifying. Well, I'm glad they're kind of lazy, 482 00:25:07,240 --> 00:25:09,320 Speaker 1: but it's also a little disappointing, like you want them 483 00:25:09,359 --> 00:25:12,160 Speaker 1: to have more personality than that. So I did read 484 00:25:12,160 --> 00:25:15,159 Speaker 1: about squid and whale battles, which are amazing, all right, 485 00:25:15,200 --> 00:25:17,400 Speaker 1: So why why is that? So? I always wondered why 486 00:25:17,480 --> 00:25:21,200 Speaker 1: colossal squid have such big eyes. It basically comes down 487 00:25:21,200 --> 00:25:23,439 Speaker 1: to whales, So like squid have the biggest eyes on 488 00:25:23,440 --> 00:25:26,399 Speaker 1: the planet, measuring over eleven inches in diameter, which is 489 00:25:26,440 --> 00:25:28,879 Speaker 1: essentially the size of a dinner plate. But the reason 490 00:25:29,000 --> 00:25:31,480 Speaker 1: is that in murky and weak light in the ocean, 491 00:25:31,880 --> 00:25:34,240 Speaker 1: you need a big eye to pick up light. But 492 00:25:34,320 --> 00:25:36,760 Speaker 1: a biologist at Duke modeled the eye and realized that 493 00:25:36,880 --> 00:25:39,680 Speaker 1: a bigger eye isn't actually good at seeing all objects. 494 00:25:39,960 --> 00:25:42,600 Speaker 1: It's just a lot better at seeing really big objects 495 00:25:42,600 --> 00:25:46,040 Speaker 1: coming at you. And according to Scientific American, that means 496 00:25:46,080 --> 00:25:49,399 Speaker 1: the squid can spot whales at a dark depths or 497 00:25:49,480 --> 00:25:51,679 Speaker 1: more hopefully enough space that they can shoot out a 498 00:25:51,680 --> 00:25:54,920 Speaker 1: cloud of ink and flee. So what about the whales though, 499 00:25:55,320 --> 00:25:57,720 Speaker 1: So what's interesting is that they don't actually need great 500 00:25:57,720 --> 00:26:00,720 Speaker 1: eyesight because they're all using sonar. But the way the 501 00:26:00,720 --> 00:26:03,879 Speaker 1: whales catch the squid is amazing. So for smaller prey, 502 00:26:03,880 --> 00:26:07,399 Speaker 1: they'll actually use these ultrasound bursts. Like the whales emit 503 00:26:07,480 --> 00:26:10,360 Speaker 1: these noises and it knocks out prey and send schools 504 00:26:10,359 --> 00:26:13,440 Speaker 1: of fish swimming. But when the scientists, said woods Holds, 505 00:26:13,480 --> 00:26:16,359 Speaker 1: studied the creatures, they realized that squids don't react to 506 00:26:16,400 --> 00:26:19,280 Speaker 1: these sonic bursts at all, So instead the whales use 507 00:26:19,359 --> 00:26:22,920 Speaker 1: this incredible twisting motion to go after them. Basically they 508 00:26:22,960 --> 00:26:25,800 Speaker 1: like wriggle and twist their bodies as they attack, and 509 00:26:25,840 --> 00:26:29,240 Speaker 1: that creates this giant, crazy vacuum which pulls in the 510 00:26:29,280 --> 00:26:31,119 Speaker 1: squid so that they can just lurk them up from 511 00:26:31,119 --> 00:26:34,400 Speaker 1: a distance. And so does that always work? No? I mean, 512 00:26:34,480 --> 00:26:36,520 Speaker 1: sometimes the giant and colossal squid are big enough to 513 00:26:36,520 --> 00:26:39,360 Speaker 1: fight back, and as Life Science points out, you can 514 00:26:39,400 --> 00:26:42,280 Speaker 1: find sperm whales with suction scars on their skin, and 515 00:26:42,320 --> 00:26:44,600 Speaker 1: that's this obvious mark of a squid that got away. 516 00:26:45,119 --> 00:26:47,119 Speaker 1: All right, Well, before we get off the squid, I 517 00:26:47,119 --> 00:26:49,560 Speaker 1: feel like we should again mention a few of our favorites. 518 00:26:49,760 --> 00:26:51,800 Speaker 1: I think I like the it was called the cock 519 00:26:51,840 --> 00:26:54,159 Speaker 1: eyed squid, you know, just because he's so funny looking. 520 00:26:54,560 --> 00:26:57,320 Speaker 1: So their left eye is usually twice as big as 521 00:26:57,359 --> 00:26:59,959 Speaker 1: the right eye is just kind of comical looking, honestly, 522 00:27:00,400 --> 00:27:03,479 Speaker 1: so it actually bulges out of the squid's head. All right, 523 00:27:03,520 --> 00:27:06,439 Speaker 1: So what's yours? Oh that's great. So my favorite is 524 00:27:06,440 --> 00:27:09,480 Speaker 1: definitely the vampire tooth is in for analis, which is 525 00:27:09,560 --> 00:27:12,320 Speaker 1: essentially the vampire squid from Hell. That's how it translates. 526 00:27:12,359 --> 00:27:15,679 Speaker 1: But everything about it is wrong. So starting with the 527 00:27:15,720 --> 00:27:19,040 Speaker 1: fact that it's actually a big woos. When it senses danger, 528 00:27:19,080 --> 00:27:22,200 Speaker 1: it bites off one of its bioluminescent arms, which then 529 00:27:22,240 --> 00:27:25,160 Speaker 1: floats away, and that sends the predator in the wrong direction. 530 00:27:25,240 --> 00:27:27,520 Speaker 1: But it just has to keep gnawing off arms to 531 00:27:28,359 --> 00:27:31,479 Speaker 1: the data backers. And also, the vampire squid from Hell 532 00:27:31,560 --> 00:27:34,879 Speaker 1: is a misnomer because it's actually an octopus. The vampire 533 00:27:35,000 --> 00:27:36,760 Speaker 1: squid from Hell I think he went on that one. 534 00:27:36,760 --> 00:27:39,000 Speaker 1: That one's pretty good. All right. So there's a lot 535 00:27:39,080 --> 00:27:41,199 Speaker 1: we won't be able to get to today, but but 536 00:27:41,280 --> 00:27:42,840 Speaker 1: I know some of that will get say, for an 537 00:27:42,840 --> 00:27:46,080 Speaker 1: episode on technologies we're stealing from the Animal Kingdom. We've 538 00:27:46,080 --> 00:27:48,919 Speaker 1: talked about doing an episode like that. You know, specifically 539 00:27:48,920 --> 00:27:52,760 Speaker 1: how cuttle fish and squid both camouflage and communicate through 540 00:27:52,840 --> 00:27:56,440 Speaker 1: changing their skin colors. There's actually a super elaborate code 541 00:27:56,480 --> 00:27:59,000 Speaker 1: that some squid use. But I also know we want 542 00:27:59,040 --> 00:28:01,040 Speaker 1: to return to the octopus us for for a bit 543 00:28:01,080 --> 00:28:04,159 Speaker 1: before we move on, yeah, and talk about octopus cities 544 00:28:04,200 --> 00:28:06,639 Speaker 1: and red wings etiquette. But let's talk about after a 545 00:28:06,680 --> 00:28:22,640 Speaker 1: little break. Welcome back to part time Genius. So will 546 00:28:22,800 --> 00:28:25,400 Speaker 1: I know you got pretty excited about this octopus community 547 00:28:25,480 --> 00:28:27,440 Speaker 1: we're reading about. I want to give us a rundown 548 00:28:27,440 --> 00:28:30,159 Speaker 1: on why an octopus city is so exciting. Yeah, that's right. 549 00:28:30,200 --> 00:28:33,040 Speaker 1: Mainly because it's called Octlantis, which is such a great 550 00:28:33,080 --> 00:28:36,760 Speaker 1: pame and it's a big deal. Partially because the gloomy octopus, 551 00:28:36,840 --> 00:28:39,720 Speaker 1: you know, a k a. The Sydney octopus, is mostly 552 00:28:39,800 --> 00:28:42,920 Speaker 1: known for being a loner. But the reason this was exciting, 553 00:28:43,080 --> 00:28:45,360 Speaker 1: and we saw this in an article in Courts, was 554 00:28:45,400 --> 00:28:48,680 Speaker 1: that the creatures were filmed exhibiting complex social behaviors that 555 00:28:48,720 --> 00:28:52,360 Speaker 1: you wouldn't imagine from a solitary animal. It's funny because 556 00:28:52,360 --> 00:28:54,880 Speaker 1: in two thousand nine there was another of these colonies 557 00:28:54,880 --> 00:28:59,400 Speaker 1: found called Octopolus, very different than actlantis, and and scientists 558 00:28:59,440 --> 00:29:02,200 Speaker 1: assumed it is this total anomaly. So it's pretty cool. 559 00:29:02,320 --> 00:29:04,440 Speaker 1: I feel like they're going to run out of octopon names. 560 00:29:04,440 --> 00:29:08,000 Speaker 1: But what actually happens there, Well, the octopus interact and 561 00:29:08,040 --> 00:29:11,120 Speaker 1: they chase each other around, and at any time there 562 00:29:11,160 --> 00:29:14,440 Speaker 1: are two to fifteen octopus and it has to be 563 00:29:14,480 --> 00:29:17,400 Speaker 1: a pretty special situation, like you know, there has to 564 00:29:17,400 --> 00:29:19,800 Speaker 1: be a good stock of food coming through pretty regularly, 565 00:29:19,960 --> 00:29:23,120 Speaker 1: and not that many habitable places in the surrounding seabed. 566 00:29:23,160 --> 00:29:25,760 Speaker 1: That makes them want to be there, and you know, 567 00:29:25,760 --> 00:29:29,080 Speaker 1: but while the gloomy octopus are solitary, it seems like 568 00:29:29,080 --> 00:29:32,240 Speaker 1: communities like this could only exist if octopus had lived 569 00:29:32,280 --> 00:29:36,160 Speaker 1: and interacted with one another for generations. Well, I do 570 00:29:36,240 --> 00:29:38,560 Speaker 1: feel like Octopus Village should be like a Nickelodeon show 571 00:29:38,600 --> 00:29:41,520 Speaker 1: where totally one flucky octopus and a bunch of sarcastic 572 00:29:41,520 --> 00:29:44,320 Speaker 1: gloomy ones. But even though for most of the show 573 00:29:44,320 --> 00:29:46,440 Speaker 1: we've been talking about living octopus, I found a couple 574 00:29:46,400 --> 00:29:50,200 Speaker 1: of things that we're fascinating about dead ones and what's that. Well, 575 00:29:50,320 --> 00:29:52,240 Speaker 1: no one pulled the research for me on how Greeks 576 00:29:52,240 --> 00:29:55,560 Speaker 1: cook octopus, and it was kind of fascinating. So the 577 00:29:55,680 --> 00:29:58,480 Speaker 1: diver slice the nerve between the eyes that instantly kills 578 00:29:58,520 --> 00:30:01,880 Speaker 1: the beasts, and it's generally not a long protracted battle. 579 00:30:02,280 --> 00:30:05,280 Speaker 1: But unlike fish, which you'd grilled right away, the octopus 580 00:30:05,360 --> 00:30:08,200 Speaker 1: is mostly water, so you really have to dry it out. 581 00:30:08,640 --> 00:30:10,720 Speaker 1: Like they'll beat the carcass up to a hundred times 582 00:30:10,720 --> 00:30:12,800 Speaker 1: on a rock to ring out the water, and then 583 00:30:12,800 --> 00:30:15,000 Speaker 1: they put the octopus on a clothesline all day and 584 00:30:15,320 --> 00:30:17,680 Speaker 1: once it's dried then you can grill it or else 585 00:30:17,720 --> 00:30:20,480 Speaker 1: you just get something that's super mushy. But this Greek 586 00:30:20,520 --> 00:30:23,680 Speaker 1: grill master told NPR quote, in the old days, when 587 00:30:23,720 --> 00:30:26,720 Speaker 1: there weren't freezers, people here used to sun the octopus 588 00:30:26,760 --> 00:30:28,840 Speaker 1: for days until it was tiny and fit into a 589 00:30:28,840 --> 00:30:32,280 Speaker 1: little caraft, but expanded to its original size when cooked. 590 00:30:32,800 --> 00:30:35,440 Speaker 1: Isn't that crazy? It's so weird. Yeah, but it also 591 00:30:35,480 --> 00:30:38,680 Speaker 1: feels maybe a little bit morbid. So why don't we 592 00:30:38,680 --> 00:30:40,400 Speaker 1: skip to this Red Wings fact that you were you 593 00:30:40,440 --> 00:30:42,520 Speaker 1: were talking about before. Well, I'm not sure it's any 594 00:30:42,600 --> 00:30:45,880 Speaker 1: less morbid, but we both know about the Red Wings 595 00:30:45,880 --> 00:30:48,120 Speaker 1: and this legend of the octopus and how people started 596 00:30:48,120 --> 00:30:51,080 Speaker 1: lobbying dead creatures on the rink after games because the 597 00:30:51,200 --> 00:30:53,320 Speaker 1: Red Wings at one time needed eight games to sweep 598 00:30:53,360 --> 00:30:55,800 Speaker 1: the series, and it kind of became a thing. But 599 00:30:55,840 --> 00:30:58,600 Speaker 1: apparently there's an art to it, really, alright, So so 600 00:30:58,640 --> 00:31:00,960 Speaker 1: what's the art to throwing the to pus? Well, the 601 00:31:00,960 --> 00:31:03,040 Speaker 1: New York Times did this great piece on it, and 602 00:31:03,120 --> 00:31:05,480 Speaker 1: the trick to tossing a large octopus onto the rink 603 00:31:05,680 --> 00:31:07,920 Speaker 1: is to boil it with wine and lemon juice or 604 00:31:07,920 --> 00:31:11,160 Speaker 1: else it's gonna stink. Also, it has to be boiled 605 00:31:11,320 --> 00:31:14,840 Speaker 1: like a well boiled octopus can travel a hundred feet 606 00:31:15,120 --> 00:31:18,040 Speaker 1: and as they put it, bounce and rolls satisfactorily or 607 00:31:18,080 --> 00:31:20,840 Speaker 1: across the ice when it lands. It's amazing what they 608 00:31:20,880 --> 00:31:22,640 Speaker 1: go through just to make this happens. All right, So 609 00:31:22,680 --> 00:31:24,840 Speaker 1: what happens if it's a rare, like a medium rare 610 00:31:24,880 --> 00:31:28,800 Speaker 1: octopus instead of well boiled. Yeah, those just splatz, which 611 00:31:28,840 --> 00:31:32,000 Speaker 1: seems equally amusing. But the article goes into these mistakes 612 00:31:32,000 --> 00:31:34,280 Speaker 1: that rookies tend to make. So you have to grab 613 00:31:34,320 --> 00:31:36,560 Speaker 1: the octopus arms in the middle, and you've got to 614 00:31:36,640 --> 00:31:38,640 Speaker 1: keep the head back and toss it from the knees 615 00:31:38,680 --> 00:31:42,719 Speaker 1: and what they describe as this over exaggerated grenade toss. 616 00:31:43,640 --> 00:31:45,200 Speaker 1: According to the piece, if you try to throw it 617 00:31:45,240 --> 00:31:47,600 Speaker 1: like a baseball or by the tips of the tentacles, 618 00:31:47,640 --> 00:31:49,680 Speaker 1: octopus parts are going to end up on your neighbor. 619 00:31:50,640 --> 00:31:52,720 Speaker 1: But the absolutely best part of the article was how 620 00:31:52,720 --> 00:31:56,400 Speaker 1: people sneak the octopus in Because while it's this beloved tradition, 621 00:31:56,720 --> 00:31:59,800 Speaker 1: management doesn't love dealing with the octopus. So people have 622 00:32:00,000 --> 00:32:03,320 Speaker 1: all these smuggling tricks, like one guy he'll wrap it 623 00:32:03,360 --> 00:32:06,080 Speaker 1: in a zip lock and wear them like a pot belly, 624 00:32:06,760 --> 00:32:09,200 Speaker 1: and others try to sneak them under really tall hats, 625 00:32:09,600 --> 00:32:12,120 Speaker 1: which just feels kind of crazy because, according to the Times, 626 00:32:12,160 --> 00:32:15,360 Speaker 1: the biggest octopus to land on the rink was thirty pounds. Wow, 627 00:32:15,360 --> 00:32:18,600 Speaker 1: it's an impressive pop. And you know, while it isn't 628 00:32:18,600 --> 00:32:20,800 Speaker 1: good for the octopus, I guess it is good for 629 00:32:20,840 --> 00:32:24,080 Speaker 1: octopus sales. I read somewhere that they actually double in 630 00:32:24,120 --> 00:32:27,880 Speaker 1: Detroit during the hockey playoffs. Yeah, that's right. I didn't 631 00:32:27,880 --> 00:32:29,920 Speaker 1: sneak a full grown octopus in here, but I did 632 00:32:29,960 --> 00:32:32,200 Speaker 1: sneak in a few extra facts. You ready for the 633 00:32:32,200 --> 00:32:43,520 Speaker 1: fact off? You know? I am all right? Well, squid 634 00:32:43,520 --> 00:32:46,280 Speaker 1: are easy to digest from many ocean creatures. The one 635 00:32:46,360 --> 00:32:50,240 Speaker 1: part that isn't is their beak. Apparently, beaks often collect 636 00:32:50,320 --> 00:32:54,560 Speaker 1: inside other sea creatures. Have you heard of Kimberrella? I 637 00:32:54,600 --> 00:32:57,440 Speaker 1: can't say that. I've heard of tiny mollis that lived 638 00:32:57,440 --> 00:33:01,040 Speaker 1: over five million years ago and is the earliest known 639 00:33:01,080 --> 00:33:04,040 Speaker 1: ancestor of the squid. Also, doesn't it sound like she 640 00:33:04,120 --> 00:33:10,080 Speaker 1: left seven slippers behind at Prince Charming's palace? She sounds beautiful, Kimbarella? 641 00:33:10,160 --> 00:33:12,040 Speaker 1: All right? So did you know that human trash can 642 00:33:12,080 --> 00:33:15,560 Speaker 1: occasionally be good for octopus that have no shelter? On 643 00:33:15,600 --> 00:33:18,360 Speaker 1: a dive off of the Puget Sound, one scientist observed 644 00:33:18,440 --> 00:33:21,880 Speaker 1: eight beer bottles, all with tiny red octopus in them. 645 00:33:21,920 --> 00:33:25,200 Speaker 1: I mean these beer bottles had occupancy, right, that's a 646 00:33:25,240 --> 00:33:29,480 Speaker 1: good right. Have you heard of the octopo tooth, this deletron? 647 00:33:29,640 --> 00:33:32,480 Speaker 1: I have not. It's a squid that doesn't have sex organs. 648 00:33:32,480 --> 00:33:35,040 Speaker 1: So the males have to put these sperm packets on 649 00:33:35,080 --> 00:33:38,520 Speaker 1: the side of their potential mates for later fertilization. But 650 00:33:38,600 --> 00:33:40,959 Speaker 1: because their eyesight isn't great in the cloudy waters, they 651 00:33:41,000 --> 00:33:43,200 Speaker 1: just tag these onto any squid they can hope with 652 00:33:43,280 --> 00:33:46,719 Speaker 1: a few of them might be females. So alright, well, 653 00:33:46,760 --> 00:33:50,200 Speaker 1: my favorite squid discovery might be the Grimaldi scaled squid. 654 00:33:50,640 --> 00:33:53,080 Speaker 1: I guess Prince Albert, the first of Monaco was an 655 00:33:53,080 --> 00:33:56,360 Speaker 1: amateur squid enthusiast, and I didn't remember this story from 656 00:33:56,360 --> 00:33:58,760 Speaker 1: mental flaws, but apparently he'd sit through what he called 657 00:33:58,760 --> 00:34:03,200 Speaker 1: the precious regurgit patians of sperm wells for specif and 658 00:34:03,240 --> 00:34:06,120 Speaker 1: because the scales of the squid were so flashy and luxurious, 659 00:34:06,360 --> 00:34:08,960 Speaker 1: he named the squid after the house he belonged to, 660 00:34:09,080 --> 00:34:12,560 Speaker 1: the House of Grimaldi luxury squid. I like that, Why 661 00:34:12,600 --> 00:34:14,680 Speaker 1: don't you take the Crown today, I can do that. 662 00:34:14,760 --> 00:34:16,640 Speaker 1: Thank you all right.
