1
00:00:00,160 --> 00:00:03,800
Speaker 1: This episode is brought to Welcome to Stuff You Should

2
00:00:03,880 --> 00:00:12,640
Speaker 1: Know from House Stuff Works dot com. Hey, and welcome

3
00:00:12,680 --> 00:00:16,720
Speaker 1: to the podcast. I'm Josh Clark. Yeah, there's Charles W.

4
00:00:16,840 --> 00:00:20,160
Speaker 1: Chuck Bryant. Jerry's over there. Uh and this is Stuff

5
00:00:20,160 --> 00:00:23,000
Speaker 1: you Should Know the podcast. That's right. How are you doing?

6
00:00:23,400 --> 00:00:26,960
Speaker 1: I'm doing great? Man? Good? How are you doing? Jerry? Jerry?

7
00:00:29,480 --> 00:00:33,000
Speaker 1: Oh goodness me. Good to be back in one A. Yeah,

8
00:00:33,600 --> 00:00:37,600
Speaker 1: it's been fighters and stuff twenty four hours. Yes, last

9
00:00:38,320 --> 00:00:41,000
Speaker 1: I saw one thing, um when I was watching a

10
00:00:41,040 --> 00:00:44,080
Speaker 1: documentary on spiders that they said, there's never You're never

11
00:00:44,120 --> 00:00:47,000
Speaker 1: more than an arm linked away from lots of spiders.

12
00:00:48,159 --> 00:00:49,960
Speaker 1: And I wondered, because I've done you. I finally did

13
00:00:49,960 --> 00:00:52,640
Speaker 1: your little trick with the flashlight. Did it work? Oh yeah, dude,

14
00:00:52,680 --> 00:00:56,680
Speaker 1: it's horrifying. They are everywhere. But I wonder about like

15
00:00:56,720 --> 00:00:59,520
Speaker 1: in this room and this it feels like hermetically sealed

16
00:00:59,520 --> 00:01:03,320
Speaker 1: concrete vault. Are there spiders in here? There's one dangling

17
00:01:03,360 --> 00:01:07,039
Speaker 1: above your head right now? I see No, they are pretty,

18
00:01:07,360 --> 00:01:10,240
Speaker 1: they're good at hiding, they're small. So you're saying they're

19
00:01:10,240 --> 00:01:12,080
Speaker 1: in here, I would guess, So, I mean, like, why

20
00:01:12,120 --> 00:01:13,960
Speaker 1: why would they not be in here, like the one

21
00:01:13,959 --> 00:01:16,800
Speaker 1: place in the world and they've been around for what

22
00:01:16,959 --> 00:01:22,080
Speaker 1: four million years? Yeah, they're pretty durable. They've spread everywhere everywhere,

23
00:01:22,640 --> 00:01:25,680
Speaker 1: and um, one of the ways that they have adapted

24
00:01:26,360 --> 00:01:31,679
Speaker 1: is by generating new species. Yeah, like to the tune

25
00:01:31,680 --> 00:01:35,520
Speaker 1: of forty thousand that we know about, and they're like,

26
00:01:35,800 --> 00:01:40,080
Speaker 1: there may be thousands of more species, not just spiders

27
00:01:40,080 --> 00:01:43,240
Speaker 1: species exactly. Um. They have a tendency to kind of

28
00:01:43,280 --> 00:01:46,319
Speaker 1: take over an area because they're actually in their realm

29
00:01:46,400 --> 00:01:52,040
Speaker 1: of existence, they're frequently apex predators. Yeah, I mean they're

30
00:01:52,080 --> 00:01:55,120
Speaker 1: they're the uh, they're they've been lined the sharks and

31
00:01:55,160 --> 00:01:58,200
Speaker 1: that they are robots that kill and eat and make

32
00:01:58,240 --> 00:02:01,360
Speaker 1: baby spiders and sort of what they do in life. Yes,

33
00:02:01,480 --> 00:02:06,640
Speaker 1: but they also do some pretty neat geometric designs. Their

34
00:02:06,680 --> 00:02:12,040
Speaker 1: spiders are pretty fascinating, super creepy things. Yeah. That thing

35
00:02:12,120 --> 00:02:14,680
Speaker 1: you sent the how they take over that? Um like

36
00:02:14,720 --> 00:02:19,680
Speaker 1: that building? Yeah, the it was Baltimore's wastewater treatment plant.

37
00:02:20,000 --> 00:02:22,440
Speaker 1: They took over four acres of it. It was abandoned, right,

38
00:02:22,600 --> 00:02:26,000
Speaker 1: No oh really, Yeah, they just got a foothold in there.

39
00:02:26,320 --> 00:02:29,520
Speaker 1: That happened while dudes were working in the building. Yeah,

40
00:02:29,560 --> 00:02:32,800
Speaker 1: they said no, they noticed, but like they what are

41
00:02:32,800 --> 00:02:35,760
Speaker 1: these guys gonna do? They're like wastewater treatment guys, not exterminators,

42
00:02:35,760 --> 00:02:38,519
Speaker 1: So they didn't know what to doator, but they well

43
00:02:38,560 --> 00:02:43,040
Speaker 1: they did. The Baltimore UM City was like, can anybody

44
00:02:43,040 --> 00:02:45,320
Speaker 1: help with this week have something of a spider problem,

45
00:02:45,600 --> 00:02:49,560
Speaker 1: and actually brought in some academics who determined that something

46
00:02:49,639 --> 00:02:54,200
Speaker 1: like there were thirty five thousand spiders per cubic meter

47
00:02:54,600 --> 00:02:57,640
Speaker 1: in that building. That is a ton of spiders, they

48
00:02:57,639 --> 00:02:59,640
Speaker 1: were saying, and in this article, I think it was

49
00:02:59,680 --> 00:03:04,840
Speaker 1: on why points out that these are mid career entomologists

50
00:03:05,400 --> 00:03:12,280
Speaker 1: who um like have seen stuff before? Did they say? Etomologists? Entomologists? Right, yeah,

51
00:03:12,360 --> 00:03:15,520
Speaker 1: yeah yeah, um. And they were like, I've never seen

52
00:03:15,600 --> 00:03:18,000
Speaker 1: anything like this before my life. So they brought in

53
00:03:18,040 --> 00:03:21,720
Speaker 1: the spider version of Quint from Jaws. Probably seems like

54
00:03:21,880 --> 00:03:25,400
Speaker 1: you're gonna have to move, you have to kill the queen. Yeah,

55
00:03:25,639 --> 00:03:27,800
Speaker 1: now I speak even he was like, where you guys

56
00:03:27,800 --> 00:03:29,960
Speaker 1: gotta go? No, there's not a queen. Because I didn't

57
00:03:30,000 --> 00:03:31,840
Speaker 1: realize this, but it makes sense when I hear it.

58
00:03:32,080 --> 00:03:35,680
Speaker 1: Spiders lead solitary lives. They bow down to no one.

59
00:03:35,960 --> 00:03:38,000
Speaker 1: They just do what they want to do yes, and

60
00:03:38,040 --> 00:03:43,960
Speaker 1: spiders are not insects. They are arachnids in the class Arachneita,

61
00:03:44,880 --> 00:03:50,440
Speaker 1: the order um arena. Even got told how to pronounce those.

62
00:03:50,480 --> 00:03:55,160
Speaker 1: I think I think it's just a didn't that what

63
00:03:55,200 --> 00:03:58,440
Speaker 1: the lady said. I think she said, like it it's

64
00:03:58,600 --> 00:04:02,839
Speaker 1: pronounced like it looks okay, so it would be aaron a. Well,

65
00:04:02,880 --> 00:04:06,040
Speaker 1: it's the same order as ticks that we've talked about

66
00:04:06,080 --> 00:04:08,960
Speaker 1: in scorpions, which I would like to cover at some point.

67
00:04:09,080 --> 00:04:15,080
Speaker 1: Scorpions and my what was that my scorpion? I thought

68
00:04:15,080 --> 00:04:18,920
Speaker 1: you were gonna sing rocky like a hurricane. I've probably

69
00:04:18,920 --> 00:04:26,200
Speaker 1: seen winds of change instead. Really, yeah, it's a good

70
00:04:26,200 --> 00:04:30,839
Speaker 1: song man. I like a little harder. I like it

71
00:04:30,880 --> 00:04:37,360
Speaker 1: all all scorpions, all the time. Alright. So spiders, because

72
00:04:37,400 --> 00:04:41,280
Speaker 1: there are forty thousand species um, they obviously differ from

73
00:04:41,640 --> 00:04:44,920
Speaker 1: the tiniest little thing to the the goliath bird eater

74
00:04:45,600 --> 00:04:48,120
Speaker 1: of Australia, which is can be as big as a

75
00:04:48,160 --> 00:04:51,200
Speaker 1: dinner plate. I think that's actually from South America. Oh

76
00:04:51,320 --> 00:04:55,120
Speaker 1: is it? Uh huh? I thought those were Australian. Australia

77
00:04:55,160 --> 00:04:58,200
Speaker 1: has plenty of spiders scary ones too, but the goliath

78
00:04:58,240 --> 00:05:01,599
Speaker 1: bird eaters. Yeah, and it's called a bird eater because

79
00:05:01,640 --> 00:05:05,000
Speaker 1: it can actually eat small birds. It does. It frequently

80
00:05:05,000 --> 00:05:08,880
Speaker 1: eats some little baby birds, but those are still birds.

81
00:05:09,400 --> 00:05:12,080
Speaker 1: And it's a spider eating a bird. There's a there's

82
00:05:12,120 --> 00:05:15,000
Speaker 1: a video that we have on the podcast page um

83
00:05:15,040 --> 00:05:20,000
Speaker 1: for this episode of a goliath spider eating a mouse

84
00:05:21,200 --> 00:05:24,560
Speaker 1: and it it's it's remarkable. Yeah, dude, I saw one

85
00:05:24,720 --> 00:05:28,680
Speaker 1: of a spider eating a viper snake what like the

86
00:05:28,720 --> 00:05:32,000
Speaker 1: snake went into the hole and the tarantula one what

87
00:05:32,320 --> 00:05:36,400
Speaker 1: And I mean they'll eat fish, they eat frogs and lizards.

88
00:05:37,360 --> 00:05:42,839
Speaker 1: Insects obviously, Yeah, but they'll eat whatever. Yeah. Yeah, they

89
00:05:42,880 --> 00:05:45,159
Speaker 1: do make it into a soup down it goes. Okay,

90
00:05:45,240 --> 00:05:47,120
Speaker 1: So I think we've kind of laid the ground where

91
00:05:47,200 --> 00:05:53,440
Speaker 1: care spiders are extraordinarily fascinating. You said they are arachnids um,

92
00:05:53,680 --> 00:05:56,520
Speaker 1: which means that they're not actually insects. And the thing

93
00:05:56,560 --> 00:05:59,880
Speaker 1: that differentiates them from insects is pretty simple. They don't

94
00:06:00,080 --> 00:06:03,680
Speaker 1: have and a true thorax. They have a cephalothorax, right,

95
00:06:04,000 --> 00:06:06,760
Speaker 1: which is the head and the thorax fused together, and

96
00:06:06,760 --> 00:06:10,680
Speaker 1: then they have the abdomen. So spiders have two segments. Yeah,

97
00:06:10,920 --> 00:06:14,719
Speaker 1: that's that's what makes them different. Yeah. And the the

98
00:06:14,760 --> 00:06:18,520
Speaker 1: segments to me seemed what they housed seemed a little backward,

99
00:06:19,320 --> 00:06:22,520
Speaker 1: like that rear segment the abdomen. I would have thought like, oh,

100
00:06:22,720 --> 00:06:25,600
Speaker 1: that's where the stomach is and all that stuff. The stomach,

101
00:06:25,720 --> 00:06:27,640
Speaker 1: the brain, the eyes, and the mouth are actually in

102
00:06:27,680 --> 00:06:31,200
Speaker 1: the front cephalothorax, and the abdomen is where the heart

103
00:06:31,839 --> 00:06:36,360
Speaker 1: and lungs, reproductive organs and digestive tract are. It seems

104
00:06:36,360 --> 00:06:38,080
Speaker 1: so a little flip floppy to me. It's like a

105
00:06:38,120 --> 00:06:40,599
Speaker 1: Ferrari where like the trunk is in the front and

106
00:06:40,640 --> 00:06:43,919
Speaker 1: the engines in the back. Yeah, or a Volkswagen the

107
00:06:43,920 --> 00:06:46,640
Speaker 1: same thing. Yeah. Yeah, well not all Volkswagons, but my

108
00:06:46,680 --> 00:06:49,479
Speaker 1: old Beadle had the rear engine. It makes them go

109
00:06:49,480 --> 00:06:53,000
Speaker 1: go go, yeah. Or it's air cold, so if it's

110
00:06:53,000 --> 00:06:57,359
Speaker 1: super hot, it makes it stop stop stop. Yeah. Another

111
00:06:57,480 --> 00:07:00,120
Speaker 1: thing that spiders have in common is they all have

112
00:07:00,200 --> 00:07:03,160
Speaker 1: eight legs, although some of them it looks like they

113
00:07:03,160 --> 00:07:08,719
Speaker 1: have ten pairs of legs. Oh no, I'm sorry, ten legs,

114
00:07:08,760 --> 00:07:11,720
Speaker 1: five pair of legs, And what that is is actually

115
00:07:11,720 --> 00:07:14,480
Speaker 1: they have something called petty palps. Oh yeah. Some of

116
00:07:14,480 --> 00:07:16,840
Speaker 1: them are longer and look leggy. Right, So it looks

117
00:07:16,880 --> 00:07:18,920
Speaker 1: like they have five pair of legs, but really it's

118
00:07:19,000 --> 00:07:21,280
Speaker 1: four pair of legs and a pair of petty palps.

119
00:07:21,280 --> 00:07:24,360
Speaker 1: And these things are basically it's like um, their four arms,

120
00:07:24,360 --> 00:07:28,000
Speaker 1: their arms, it's like a squirrel. Imagine a squirrel, spidery

121
00:07:28,280 --> 00:07:31,400
Speaker 1: little tiny little front arms. Yeah, eating a nut or

122
00:07:31,640 --> 00:07:36,480
Speaker 1: a mouse or a viper um what else? All spiders

123
00:07:36,520 --> 00:07:39,679
Speaker 1: spin silk, right yeah, but not all of them spin webs,

124
00:07:40,080 --> 00:07:42,000
Speaker 1: right yeah, but they all of them are capable of

125
00:07:42,040 --> 00:07:44,920
Speaker 1: creating silk, which we'll talk about. To me, that's the

126
00:07:44,960 --> 00:07:48,720
Speaker 1: gold that's just amazing, and other there are other insects

127
00:07:48,720 --> 00:07:53,680
Speaker 1: that can spin silk like silkworms. Nothing in nature is

128
00:07:53,800 --> 00:08:00,160
Speaker 1: like spider silk, though it's strong, it's elastic. Um. For example, well,

129
00:08:00,200 --> 00:08:02,400
Speaker 1: if you are a spider and you build a web,

130
00:08:02,760 --> 00:08:06,320
Speaker 1: you can trap a bumblebee, a big old bumblebee at

131
00:08:06,360 --> 00:08:10,600
Speaker 1: full speed, and your your um web will be able

132
00:08:10,640 --> 00:08:14,120
Speaker 1: to withstand the impact. It's it's a huge, huge, massive

133
00:08:14,160 --> 00:08:17,960
Speaker 1: impact and you're the tensile strength of your web is

134
00:08:18,000 --> 00:08:20,720
Speaker 1: going to take it like nothing. Yeah. I think I

135
00:08:20,720 --> 00:08:23,160
Speaker 1: saw one thing that said it was a hundred times

136
00:08:23,200 --> 00:08:27,360
Speaker 1: stronger than a human ligament. That's strong. Yeah, stronger than

137
00:08:27,440 --> 00:08:32,400
Speaker 1: steel even that's strong. But again that's a tease. We're

138
00:08:32,400 --> 00:08:35,560
Speaker 1: gonna cover silk here in full. Um. But back to

139
00:08:35,640 --> 00:08:39,160
Speaker 1: the body, my friend. Uh, Spiders breathe in a very

140
00:08:39,200 --> 00:08:42,880
Speaker 1: basic way but fascinating. They have a trachea and what

141
00:08:42,920 --> 00:08:46,560
Speaker 1: are called booklongs. Uh. Most of the species have both,

142
00:08:46,600 --> 00:08:50,760
Speaker 1: some just have one. Um, but it's really a different thing.

143
00:08:50,880 --> 00:08:53,960
Speaker 1: What what they do is air flows in uh through

144
00:08:54,040 --> 00:08:57,720
Speaker 1: these basically slits and the exoskeleton, which is the trachea,

145
00:08:58,200 --> 00:09:01,360
Speaker 1: and then there's just a lot of osmosis but diffusion

146
00:09:01,400 --> 00:09:04,760
Speaker 1: bass exchange. Yeah, but it's not like I'm breathing in air.

147
00:09:04,880 --> 00:09:07,640
Speaker 1: It's just air is being diffused in and CEO two

148
00:09:07,760 --> 00:09:10,319
Speaker 1: is diffused out right, and the movement of the spider

149
00:09:10,360 --> 00:09:13,160
Speaker 1: actually pushes air through these trichia. Yeah, it's not like

150
00:09:13,160 --> 00:09:15,640
Speaker 1: a lung that breathes quote unquote. And then they do

151
00:09:15,760 --> 00:09:20,719
Speaker 1: have most species have both trichia and booklongs. Um. But

152
00:09:21,440 --> 00:09:24,600
Speaker 1: the booklung kind of is like an extra well, it's

153
00:09:24,600 --> 00:09:27,120
Speaker 1: an extra lung. It's an extra place where gas exchange

154
00:09:27,160 --> 00:09:30,920
Speaker 1: takes place. And um, they're called book lungs because it

155
00:09:30,960 --> 00:09:34,600
Speaker 1: looks like an open book that's being flopped open, So

156
00:09:34,679 --> 00:09:39,439
Speaker 1: there's different leads and um. Those leaves are filled with blood,

157
00:09:39,960 --> 00:09:42,800
Speaker 1: but the exterior of them become in contact with air,

158
00:09:43,200 --> 00:09:45,920
Speaker 1: so that's where the gas exchange takes place. Yeah. And

159
00:09:46,040 --> 00:09:50,600
Speaker 1: speaking of the blood, it's called hemo lymph and it

160
00:09:50,720 --> 00:09:54,120
Speaker 1: circulates O two and nutrients and hormones at all. But

161
00:09:54,320 --> 00:09:58,520
Speaker 1: um again and sort of a fascinating way. It has

162
00:09:58,559 --> 00:10:02,080
Speaker 1: a simple heart that's just like uh, pump in, pump out,

163
00:10:02,559 --> 00:10:05,320
Speaker 1: and it basically just saturates all the organs and blood

164
00:10:05,559 --> 00:10:08,000
Speaker 1: and that's where they get their oxygen. Yeah. It's not

165
00:10:08,040 --> 00:10:13,199
Speaker 1: a closed system where like your your your arm is

166
00:10:13,240 --> 00:10:17,800
Speaker 1: getting blood because blood vessels are are carrying or carrying

167
00:10:17,800 --> 00:10:21,240
Speaker 1: blood to it. It's like your entire arm, everything beneath

168
00:10:21,280 --> 00:10:23,320
Speaker 1: your skin would be full of blood. Yeah, and so

169
00:10:23,400 --> 00:10:26,360
Speaker 1: everything in there that needs oxygen or hormones or whatever

170
00:10:26,360 --> 00:10:28,760
Speaker 1: it is getting them just from being bathed in this stuff. Yeah,

171
00:10:28,840 --> 00:10:34,240
Speaker 1: it's pretty remarkable. It is brains, they've got them. Yeah,

172
00:10:34,320 --> 00:10:38,800
Speaker 1: they are tiny little brains, and some spiders are smarter

173
00:10:39,480 --> 00:10:43,840
Speaker 1: than others, but in general, spiders, the way I read

174
00:10:43,840 --> 00:10:47,960
Speaker 1: it was, are sort of like little chemically signaled robots

175
00:10:48,520 --> 00:10:50,719
Speaker 1: it's just chemical signals flying all over the place that

176
00:10:50,800 --> 00:10:54,520
Speaker 1: operate everything. I think the jumping spiders are the smartest one.

177
00:10:54,840 --> 00:10:58,680
Speaker 1: Well yeah, and it's kind of making it's puzzling science.

178
00:10:58,760 --> 00:11:03,360
Speaker 1: So there's they have ganglia. They don't even have true

179
00:11:03,360 --> 00:11:07,280
Speaker 1: brains spiders exactly, and they're like little nerve bundles and

180
00:11:07,280 --> 00:11:11,360
Speaker 1: that's where all their impulses are originate, and that transfers

181
00:11:11,360 --> 00:11:14,960
Speaker 1: the signals to the rest of their body. Um. And

182
00:11:15,200 --> 00:11:20,040
Speaker 1: in a jumping spider, the ganglia amounts to about a

183
00:11:20,120 --> 00:11:25,600
Speaker 1: hundred thousand neurons, just tiny, tiny, tiny amount of brain power,

184
00:11:26,240 --> 00:11:29,360
Speaker 1: and yet their vision is about on par with human vision.

185
00:11:31,200 --> 00:11:35,320
Speaker 1: The jumping spider jumper, yes, the great They have eight

186
00:11:35,320 --> 00:11:40,040
Speaker 1: eyes with almost three hundred and sixty degree vision um

187
00:11:40,120 --> 00:11:44,760
Speaker 1: and they can see very clearly their surroundings. But again

188
00:11:44,840 --> 00:11:47,720
Speaker 1: they're doing this with a hundred thousand neurons. So roboticists

189
00:11:47,760 --> 00:11:49,880
Speaker 1: and a lot of other smart people are looking into

190
00:11:49,920 --> 00:11:52,520
Speaker 1: this to see like where this sufficiency is taking place,

191
00:11:52,600 --> 00:11:56,080
Speaker 1: Like how you can generate that level of clarity and

192
00:11:56,120 --> 00:12:00,000
Speaker 1: information from just a hundred thousand neurons. Yeah, they think, um,

193
00:12:00,200 --> 00:12:02,840
Speaker 1: they don't think. They know that. They like to drink

194
00:12:02,920 --> 00:12:09,199
Speaker 1: human blood jumping spiders, but from mosquitoes, and supposedly by

195
00:12:09,280 --> 00:12:12,240
Speaker 1: looking at a mosquito they can tell if it has

196
00:12:12,280 --> 00:12:16,719
Speaker 1: blood in it or not, just from vision. Um and

197
00:12:16,720 --> 00:12:18,600
Speaker 1: I don't think they figured that out either, but they've

198
00:12:18,600 --> 00:12:21,840
Speaker 1: seen clearly that every experiment they go to the mosquito

199
00:12:21,880 --> 00:12:25,959
Speaker 1: with the blood, which is remarkable, jumping like fifty times

200
00:12:26,000 --> 00:12:30,000
Speaker 1: their body length to to pounce on whatever it is. Yeah,

201
00:12:30,120 --> 00:12:33,040
Speaker 1: So imagine being a human and jumping even one time

202
00:12:33,120 --> 00:12:36,120
Speaker 1: your own body length, your height, you know, like a

203
00:12:36,200 --> 00:12:41,320
Speaker 1: standing broad jump. Yeah, but right, that's not gonna happen.

204
00:12:41,360 --> 00:12:44,000
Speaker 1: These guys can do fifty times, and they do it

205
00:12:44,120 --> 00:12:49,920
Speaker 1: quick to super fast. Spiders are amazing. Hey, maybe that's

206
00:12:49,920 --> 00:12:52,880
Speaker 1: why they called the comic the Amazing Spider Man. Oh maybe.

207
00:12:53,040 --> 00:12:54,959
Speaker 1: And it's funny. When I was reading all this stuff,

208
00:12:55,160 --> 00:12:57,760
Speaker 1: every like ten seconds, I was like, oh, just like

209
00:12:57,840 --> 00:13:01,160
Speaker 1: Spider Man, so clearly stand like to this research. Well,

210
00:13:01,200 --> 00:13:05,360
Speaker 1: what's funny is like this this article by old Tom Harris.

211
00:13:06,000 --> 00:13:09,200
Speaker 1: Um old Man Harris tries to like it compares like

212
00:13:09,320 --> 00:13:12,480
Speaker 1: spiders to humans throughout the whole thing. Yeah, just like

213
00:13:12,559 --> 00:13:17,720
Speaker 1: human spiders have a brain, but not really Yeah. Um And,

214
00:13:17,800 --> 00:13:20,600
Speaker 1: speaking of Spider Man, I guess spidy sense is sort

215
00:13:20,600 --> 00:13:23,480
Speaker 1: of what's uh really going on. They do have those

216
00:13:23,520 --> 00:13:26,959
Speaker 1: eyes and while this jumping spider can see really well,

217
00:13:27,280 --> 00:13:31,080
Speaker 1: most spiders it's a secondary sense and they use that

218
00:13:31,120 --> 00:13:35,000
Speaker 1: spidy sense that can feel vibrations like remarkably well feel it,

219
00:13:35,120 --> 00:13:40,880
Speaker 1: feel it is that good vibrations. Um. So they can

220
00:13:40,920 --> 00:13:45,040
Speaker 1: sense anything from like a long way away and sort

221
00:13:45,080 --> 00:13:47,520
Speaker 1: of know what it is, even especially if something's in

222
00:13:47,520 --> 00:13:51,040
Speaker 1: the web. So they've got hairs all over their body right, Um.

223
00:13:51,080 --> 00:13:55,920
Speaker 1: They also have additional hairs called trick of both for you. Yeah,

224
00:13:56,120 --> 00:13:59,960
Speaker 1: and those the the hairs um the rest of their

225
00:14:00,040 --> 00:14:03,360
Speaker 1: body or basically like, um, it's touching the ground, so

226
00:14:03,360 --> 00:14:05,920
Speaker 1: we can sense like movement on the ground or vibration

227
00:14:05,960 --> 00:14:08,280
Speaker 1: of the ground or in their web or something like that.

228
00:14:08,640 --> 00:14:13,240
Speaker 1: But the trick of both the hair can sense movement

229
00:14:13,320 --> 00:14:15,920
Speaker 1: in the air. Like. That's how sensitive this is. And

230
00:14:15,920 --> 00:14:20,240
Speaker 1: this is how spiders really sense their environment. Yeah. And

231
00:14:20,360 --> 00:14:23,960
Speaker 1: they can also taste, unlike snakes um the one that

232
00:14:24,000 --> 00:14:28,040
Speaker 1: we just released, um and smell. Yeah, so they pretty

233
00:14:28,040 --> 00:14:31,800
Speaker 1: well defined senses and they they really enjoy the taste

234
00:14:31,800 --> 00:14:35,400
Speaker 1: of mouse brains, like they really save for it mouse

235
00:14:35,480 --> 00:14:40,080
Speaker 1: brain soup. Uh, speaking of feet and legs, I had

236
00:14:40,120 --> 00:14:43,680
Speaker 1: no idea this was the case. Um, they have this adaptation.

237
00:14:44,080 --> 00:14:46,760
Speaker 1: Like we said, there are lots of thick hairs on

238
00:14:46,800 --> 00:14:50,560
Speaker 1: the legs and um, at the bottom of each hair

239
00:14:51,600 --> 00:14:54,800
Speaker 1: on the feet, well our feet. Yeah, so at the

240
00:14:54,920 --> 00:14:57,440
Speaker 1: end of tons of hair at the end of each

241
00:14:57,520 --> 00:15:00,160
Speaker 1: leg and they have eight legs, but on the end

242
00:15:00,160 --> 00:15:02,400
Speaker 1: of each hair or a bunch of feet like you say, yeah,

243
00:15:02,400 --> 00:15:05,080
Speaker 1: a little feet and then they can drip onto like anything, Yeah,

244
00:15:05,120 --> 00:15:08,120
Speaker 1: except the bathtub. Was that a joke or something? Or

245
00:15:08,160 --> 00:15:10,120
Speaker 1: is that like a well known thing about spiders that

246
00:15:10,160 --> 00:15:12,800
Speaker 1: they can't walk on bathtubs, because I don't know what

247
00:15:12,840 --> 00:15:16,440
Speaker 1: that means. I think bathtubs are a place where you

248
00:15:16,480 --> 00:15:19,160
Speaker 1: find spiders a lot of times because they can't get out.

249
00:15:20,800 --> 00:15:22,680
Speaker 1: So you'll be like, oh, there's a spider in the bathtub,

250
00:15:22,720 --> 00:15:25,440
Speaker 1: and you see it just going near and sliding back down.

251
00:15:26,080 --> 00:15:27,280
Speaker 1: So I think that was a bit of a joke,

252
00:15:28,600 --> 00:15:30,200
Speaker 1: and that's my guess. Have you ever had one come

253
00:15:30,200 --> 00:15:33,720
Speaker 1: out of the faucet the bathtub faucet? No, huh, that's

254
00:15:33,720 --> 00:15:37,360
Speaker 1: always fun. I was terrified for a brief time as

255
00:15:37,360 --> 00:15:39,640
Speaker 1: a kid because I went to turn on my bath

256
00:15:39,680 --> 00:15:41,480
Speaker 1: water and like put my hand down and like a

257
00:15:41,520 --> 00:15:45,360
Speaker 1: spider came out. And so for several years afterward, I

258
00:15:45,480 --> 00:15:49,200
Speaker 1: was petrified. Yeah, I was just a stinky little boy.

259
00:15:51,000 --> 00:15:54,200
Speaker 1: And that was last year. All right, So let's take

260
00:15:54,240 --> 00:15:57,160
Speaker 1: a break and then after that we will talk about

261
00:15:58,200 --> 00:16:07,359
Speaker 1: the malting process and a little it about spider silk.

262
00:16:17,680 --> 00:16:19,480
Speaker 1: All right, are we at the skeleton? I think we

263
00:16:19,560 --> 00:16:23,560
Speaker 1: are man exoskeleton. Yes, spiders have skeleton just like humans,

264
00:16:24,120 --> 00:16:27,320
Speaker 1: except it's on the outside exactly. Um, and they move

265
00:16:28,120 --> 00:16:34,120
Speaker 1: using muscles, right, but strangely they only half moved using muscles. Yeah,

266
00:16:34,160 --> 00:16:36,160
Speaker 1: this was just so interesting to me. It seems like

267
00:16:36,160 --> 00:16:39,920
Speaker 1: a mal adaptation. Oh yeah, yeah, like something they should

268
00:16:39,920 --> 00:16:44,280
Speaker 1: be able to do. Yeah. Um, spiders are able to

269
00:16:44,320 --> 00:16:49,520
Speaker 1: contract their muscles right, so they can move their legs inward,

270
00:16:50,480 --> 00:16:54,120
Speaker 1: and that's how they take a step and then to

271
00:16:54,200 --> 00:16:58,160
Speaker 1: complete the step. Rather than having muscles expand to move

272
00:16:58,200 --> 00:17:01,320
Speaker 1: the legs outward, again, they don't. They all have those

273
00:17:01,400 --> 00:17:06,200
Speaker 1: muscles for some reason. Instead, they pump hemo lymph into

274
00:17:06,240 --> 00:17:10,200
Speaker 1: their legs using hydraulic pressure to force them back out.

275
00:17:10,480 --> 00:17:15,200
Speaker 1: So muscles hydraulic pressure, muscles hydraulic pressure. It's so strange

276
00:17:15,359 --> 00:17:19,040
Speaker 1: it is really strange, but it clearly works well. It works.

277
00:17:19,119 --> 00:17:24,680
Speaker 1: Sometimes there's a spider can suffer from dehydration basically to

278
00:17:24,800 --> 00:17:29,160
Speaker 1: where it doesn't have enough hemo lymph to um which

279
00:17:29,200 --> 00:17:32,840
Speaker 1: is blood again to pump in to create the hydraulic

280
00:17:32,880 --> 00:17:35,840
Speaker 1: pressure necessary to make its legs move out. So if

281
00:17:35,880 --> 00:17:37,359
Speaker 1: you ever see a spider on its back with its

282
00:17:37,440 --> 00:17:41,160
Speaker 1: legs all curved inward, that's a dehydrated spider right there,

283
00:17:41,480 --> 00:17:44,760
Speaker 1: may handsome caterade. It may not be dead yet, basically

284
00:17:45,440 --> 00:17:48,680
Speaker 1: right right, and he'll tell you too, not dead yet,

285
00:17:48,760 --> 00:17:51,439
Speaker 1: Just poke it and then give him a drink and

286
00:17:51,480 --> 00:17:56,800
Speaker 1: send him along his way. The exoskeleton itself is um

287
00:17:56,880 --> 00:18:02,239
Speaker 1: made of cuticle, and it's basically proteins like kitan and

288
00:18:02,359 --> 00:18:07,040
Speaker 1: sugars like polysaccharides, and they're just stretched out and layered

289
00:18:07,119 --> 00:18:10,000
Speaker 1: upon each other to make it super strong. It's like

290
00:18:10,040 --> 00:18:13,399
Speaker 1: a really strong shell. It is for protection, obviously, but

291
00:18:13,440 --> 00:18:17,840
Speaker 1: the problem is that shell, once it's hardened, it doesn't

292
00:18:17,920 --> 00:18:22,920
Speaker 1: keep growing, although the spider does so. Much like snakes

293
00:18:22,960 --> 00:18:27,440
Speaker 1: and lots of other animals, spiders have adapted revolved to

294
00:18:28,119 --> 00:18:32,200
Speaker 1: mold to get rid of their old exoskeleton and um

295
00:18:32,240 --> 00:18:35,159
Speaker 1: a bunch of hormones trigger this. When it's time to

296
00:18:35,200 --> 00:18:39,879
Speaker 1: start growing. Uh, the spider will, I think, just like

297
00:18:39,920 --> 00:18:44,399
Speaker 1: a snake, start to absorb some of the inner layer

298
00:18:44,440 --> 00:18:47,719
Speaker 1: of the exoskeleton, right, and it becomes a little liquefied,

299
00:18:47,920 --> 00:18:53,320
Speaker 1: and they create this um, this fluid barrier between the

300
00:18:53,320 --> 00:18:57,720
Speaker 1: old exoskeleton and the new exo skeleton that they're growing. Yeah,

301
00:18:57,840 --> 00:19:02,320
Speaker 1: just like a little gap, basically a liquid gap, right exactly.

302
00:19:02,680 --> 00:19:07,440
Speaker 1: And the as the new exoskeleton starts to get grow

303
00:19:07,480 --> 00:19:10,240
Speaker 1: a little more and a little more, eventually absorbs that

304
00:19:10,440 --> 00:19:14,159
Speaker 1: fluid and then now there's like a a gap, a

305
00:19:14,200 --> 00:19:16,960
Speaker 1: real gap in between the all exo skeleton and the

306
00:19:16,960 --> 00:19:20,119
Speaker 1: new one. Yeah, and then it's um it's basically trapped

307
00:19:20,160 --> 00:19:24,040
Speaker 1: inside this old skeleton and does a little incredible hulk

308
00:19:24,160 --> 00:19:28,359
Speaker 1: move where it pumps that the blood again the hemo

309
00:19:28,440 --> 00:19:32,520
Speaker 1: lymph and expands the cephalothorax and it just like bust

310
00:19:32,560 --> 00:19:35,639
Speaker 1: out of it and then just keeps wriggling around until

311
00:19:35,640 --> 00:19:38,960
Speaker 1: it's completely out of it. But it's pants never fully

312
00:19:39,040 --> 00:19:45,040
Speaker 1: rip off. That always bugged me. It's just so unlikely

313
00:19:45,080 --> 00:19:48,320
Speaker 1: that a guy in like a thirty two ways can

314
00:19:48,400 --> 00:19:51,560
Speaker 1: become this like tin foot giant, right, it just is

315
00:19:51,640 --> 00:19:54,240
Speaker 1: like the lower calves and ankles were big enough to

316
00:19:54,359 --> 00:19:57,280
Speaker 1: rip his pants into tatters down there? What about the

317
00:19:57,280 --> 00:20:03,080
Speaker 1: waist and the thighs. No pulks would be naked, you know, technically, yes,

318
00:20:04,520 --> 00:20:07,600
Speaker 1: And again Stanley really studied spiders, so you'd think he

319
00:20:07,640 --> 00:20:10,399
Speaker 1: would know that about the hulks pants. But all right,

320
00:20:10,480 --> 00:20:12,959
Speaker 1: so after they have molted um, this is when they

321
00:20:13,000 --> 00:20:16,920
Speaker 1: do most of their growing because their new exoskeleton is um.

322
00:20:16,960 --> 00:20:19,560
Speaker 1: It's not quite fully hard yet. It can expand a

323
00:20:19,560 --> 00:20:23,119
Speaker 1: little bit at this point, but they're super vulnerable because

324
00:20:23,160 --> 00:20:24,960
Speaker 1: it's not as hard at that point as well. Right,

325
00:20:24,960 --> 00:20:26,560
Speaker 1: so they'll just kind of go off and be like,

326
00:20:26,640 --> 00:20:28,760
Speaker 1: let me alone, let me alone, let me alone. I

327
00:20:28,840 --> 00:20:31,280
Speaker 1: know him, the apex predator, but I've made a lot

328
00:20:31,320 --> 00:20:34,240
Speaker 1: of enemies along the way. They are looking for me

329
00:20:34,359 --> 00:20:36,560
Speaker 1: right now. So Chuck, we can't really put it off

330
00:20:36,560 --> 00:20:39,080
Speaker 1: any longer. And I don't know why we would. Time

331
00:20:39,080 --> 00:20:42,960
Speaker 1: to get silky. Yeah, we're gonna talk about spider silk. Uh.

332
00:20:43,000 --> 00:20:45,200
Speaker 1: It's amazing. We talked already a little bit about its

333
00:20:45,400 --> 00:20:50,200
Speaker 1: tensil strength, stronger than steel or kevlar um. And here's

334
00:20:50,240 --> 00:20:54,080
Speaker 1: the neat thing is that it's actually a liquid when

335
00:20:54,080 --> 00:20:56,600
Speaker 1: it comes out until you start stretching it and then

336
00:20:56,680 --> 00:21:00,359
Speaker 1: it becomes a solid. Right, it's extruded from spiggott and

337
00:21:00,440 --> 00:21:05,199
Speaker 1: the spiders um spinnerets. Right, So the spinnerets are um

338
00:21:05,920 --> 00:21:09,639
Speaker 1: these little pairs of almost like arms or whatever that

339
00:21:09,720 --> 00:21:14,919
Speaker 1: the spiders like this kind of yeah, As the silk

340
00:21:15,160 --> 00:21:19,120
Speaker 1: is the silk which is made up of amino acids

341
00:21:19,160 --> 00:21:22,480
Speaker 1: in like a water solution, like you said, when it's extruded,

342
00:21:22,880 --> 00:21:25,359
Speaker 1: the spider can do all sorts of different things with this.

343
00:21:25,440 --> 00:21:30,080
Speaker 1: And depending on how much um like pressure it applies

344
00:21:30,119 --> 00:21:31,879
Speaker 1: that the spigot or whatever, it could be a really

345
00:21:31,920 --> 00:21:34,800
Speaker 1: thin strand, it can be a thicker strand, it can

346
00:21:34,840 --> 00:21:37,680
Speaker 1: be short long, it could be a thin strand encased

347
00:21:37,720 --> 00:21:40,240
Speaker 1: in the thicker strand. They can do all sorts of

348
00:21:40,280 --> 00:21:43,880
Speaker 1: really neat stuff with their um their silk, so much

349
00:21:43,920 --> 00:21:47,000
Speaker 1: so that that researchers still aren't a hundred percent sure

350
00:21:47,480 --> 00:21:49,800
Speaker 1: what the heck is going on here, but they just

351
00:21:49,920 --> 00:21:52,399
Speaker 1: know that the spiders can do tons of different stuff

352
00:21:52,560 --> 00:21:56,040
Speaker 1: with just the silk proteins alone and the extrusion. Once

353
00:21:56,119 --> 00:21:59,160
Speaker 1: they come out, the spider can weed these things together

354
00:21:59,480 --> 00:22:03,000
Speaker 1: to create even stronger thread and again, this is stuff

355
00:22:03,040 --> 00:22:09,119
Speaker 1: that apparently it's uh several times stronger wait for weight

356
00:22:09,160 --> 00:22:13,920
Speaker 1: than steel. Yeah, and kevlar. So it's five times as

357
00:22:13,920 --> 00:22:16,520
Speaker 1: strong as an equal massive steel and twice as strong

358
00:22:16,520 --> 00:22:20,639
Speaker 1: as an equal massive kevlar. And remember with them the

359
00:22:20,680 --> 00:22:25,520
Speaker 1: bulletproof vest episode, we talked about using goat's milk to

360
00:22:25,560 --> 00:22:28,480
Speaker 1: produce spider silk. Yeah, they're doing it. Yeah, they definitely are.

361
00:22:28,640 --> 00:22:32,000
Speaker 1: They're not using it for uh, they haven't applied it yet,

362
00:22:32,520 --> 00:22:37,080
Speaker 1: but they do have um goat farms. They basically found, uh,

363
00:22:37,160 --> 00:22:41,480
Speaker 1: the genetic code specifically that creates the drag line. And

364
00:22:41,520 --> 00:22:44,320
Speaker 1: the drag line is the um that's sort of the

365
00:22:44,359 --> 00:22:47,399
Speaker 1: most common silk that it will spin. It's like a line.

366
00:22:48,040 --> 00:22:50,240
Speaker 1: It's like a mountain climber's rope they'll leave behind them

367
00:22:50,680 --> 00:22:52,760
Speaker 1: and in case it needs to like retreat quickly, it'll

368
00:22:52,760 --> 00:22:55,080
Speaker 1: have a little rope to pull itself along. So that's

369
00:22:55,119 --> 00:22:59,520
Speaker 1: the drag line. So they isolated the genetic code for

370
00:22:59,560 --> 00:23:02,800
Speaker 1: this drag line, put that in the goat embryo implanet

371
00:23:02,840 --> 00:23:05,760
Speaker 1: and a mama goat and the goat came out like

372
00:23:05,960 --> 00:23:09,080
Speaker 1: why they don't even know? That's the beauty of it.

373
00:23:09,440 --> 00:23:11,520
Speaker 1: They milk the goat and then from that point it's

374
00:23:11,520 --> 00:23:14,120
Speaker 1: a little bit like making cheese um from what I saw,

375
00:23:14,720 --> 00:23:16,960
Speaker 1: like they separate the they skim the fat off, and

376
00:23:16,960 --> 00:23:21,280
Speaker 1: it's like separating curds from way and then potentially we

377
00:23:21,320 --> 00:23:25,920
Speaker 1: could have like ligament replacement with spider or heart. Yeah,

378
00:23:26,000 --> 00:23:29,600
Speaker 1: they're looking to regrow human hearts with this stuff. Can

379
00:23:29,600 --> 00:23:33,840
Speaker 1: you imagine having a new heart grown from spider silk

380
00:23:34,040 --> 00:23:39,040
Speaker 1: made from goat's milk pumping in your chest. It's pretty neat. Yeah,

381
00:23:39,359 --> 00:23:42,040
Speaker 1: I think i'd tell people about that, be like, let

382
00:23:42,040 --> 00:23:45,200
Speaker 1: me tell you about my new heart exactly. That's ado

383
00:23:45,320 --> 00:23:50,800
Speaker 1: with spiders, goats and my poor diet a lot of

384
00:23:50,840 --> 00:23:53,840
Speaker 1: steak um, which is not true. What do you mean

385
00:23:53,920 --> 00:23:56,639
Speaker 1: misteak is not bad for you? Oh right right? Too

386
00:23:56,920 --> 00:24:00,639
Speaker 1: much medic myth? Is that the deal? Yeah, fats and

387
00:24:00,680 --> 00:24:04,760
Speaker 1: stuff like that. Uh. They think that the silk glands

388
00:24:04,760 --> 00:24:08,520
Speaker 1: originally started out as just ways to mark territory, like

389
00:24:08,560 --> 00:24:11,840
Speaker 1: a scent gland, and then they realize, I'm actually can

390
00:24:11,920 --> 00:24:15,600
Speaker 1: leave a substance behind that's super strong. As it turns

391
00:24:15,600 --> 00:24:18,320
Speaker 1: out super strong, and again also pound for pound, it's

392
00:24:18,359 --> 00:24:23,240
Speaker 1: as flexible as um rubber, natural rubber. Yeah. So it's

393
00:24:23,240 --> 00:24:26,520
Speaker 1: pretty amazing stuff. And again, the spider can do all

394
00:24:26,520 --> 00:24:28,080
Speaker 1: sorts of different things with it. And one of the

395
00:24:28,080 --> 00:24:30,080
Speaker 1: things you said is create the drag line, which is

396
00:24:30,119 --> 00:24:32,680
Speaker 1: like a trail of bread crumbs for an emergency. Yeah,

397
00:24:33,040 --> 00:24:36,160
Speaker 1: most spiders, that's the most common use of spider silk,

398
00:24:36,200 --> 00:24:38,800
Speaker 1: I believe, across species. Right, just like I'm gonna go

399
00:24:39,080 --> 00:24:41,640
Speaker 1: fifteen feet that way, and I'm gonna leave my little

400
00:24:41,680 --> 00:24:43,960
Speaker 1: drag line behind in case I need to hide. Tell

401
00:24:43,960 --> 00:24:46,480
Speaker 1: it out of there. Yep. They also have other glands

402
00:24:46,520 --> 00:24:51,600
Speaker 1: that can produce substances to put onto the spider silk,

403
00:24:51,920 --> 00:24:55,680
Speaker 1: like sticky stuff, which is very useful in creating webs

404
00:24:55,800 --> 00:25:00,280
Speaker 1: or water resistant materials. Yep. Um, basically like spray net

405
00:25:00,320 --> 00:25:06,680
Speaker 1: with what's this stuff? Just blank? When like for gortex

406
00:25:06,720 --> 00:25:11,840
Speaker 1: he spray uh Scotch card, Scotch card. Yeah, yeah, exactly. Um.

407
00:25:12,080 --> 00:25:16,040
Speaker 1: Female spiders will use uh, they'll make protective cocoons. Sometimes.

408
00:25:16,119 --> 00:25:18,480
Speaker 1: If you're in your basement and you see a big

409
00:25:18,920 --> 00:25:22,159
Speaker 1: looks like a cotton ball full of eggs, that's a

410
00:25:22,200 --> 00:25:24,920
Speaker 1: spider's sack. Yeah, it's a cocoon they've they've woven to

411
00:25:25,000 --> 00:25:27,879
Speaker 1: help out their little little guys and gals survive. And

412
00:25:27,920 --> 00:25:31,080
Speaker 1: then did you see the net cast? No, I'm I

413
00:25:31,200 --> 00:25:33,520
Speaker 1: ran across in this article, but I haven't seen one. Yeah,

414
00:25:33,560 --> 00:25:36,640
Speaker 1: you can just google on YouTube or whatever net casting

415
00:25:36,640 --> 00:25:40,640
Speaker 1: spider And it's basically like a little uh fishing net

416
00:25:40,920 --> 00:25:43,280
Speaker 1: that they'll weave between and hold it between their legs

417
00:25:43,280 --> 00:25:45,359
Speaker 1: like a sheet, and then something walks by and they

418
00:25:45,400 --> 00:25:47,800
Speaker 1: just throw it over their head real quick and like

419
00:25:47,880 --> 00:25:49,399
Speaker 1: wrap them up in it. You can throw it in

420
00:25:49,400 --> 00:25:55,399
Speaker 1: the van and drive off. Basically, So the probably the

421
00:25:55,400 --> 00:25:58,520
Speaker 1: most famous and I can't believe I even just said probably,

422
00:25:58,560 --> 00:26:03,000
Speaker 1: but the most famous you of spider silk in nature

423
00:26:03,240 --> 00:26:06,760
Speaker 1: is to spider webs. Yeah, the most amazing thing you

424
00:26:06,800 --> 00:26:10,119
Speaker 1: will see is an orb weaved web. And there's a

425
00:26:10,160 --> 00:26:12,280
Speaker 1: lot of the orb weaved. Is the good one that's

426
00:26:12,320 --> 00:26:16,160
Speaker 1: the geometric looking. They clearly care about it. There are

427
00:26:16,160 --> 00:26:18,720
Speaker 1: plenty of other spiders that really don't care what their

428
00:26:18,760 --> 00:26:22,960
Speaker 1: webs look like the right. Yeah, they drink out of

429
00:26:23,040 --> 00:26:26,440
Speaker 1: mugs that they're like, I hate mondays and stuff. They

430
00:26:26,520 --> 00:26:29,159
Speaker 1: just don't care about their web. Like black widows actually

431
00:26:29,160 --> 00:26:32,280
Speaker 1: make terrible stupid webs. Yeah, and you would think like

432
00:26:32,359 --> 00:26:37,560
Speaker 1: they're sleek, they're they're vicious symbol. Yeah, but they don't

433
00:26:37,560 --> 00:26:39,600
Speaker 1: care what their web looks like. And what are you

434
00:26:39,640 --> 00:26:42,480
Speaker 1: gonna do. I'll bite you, yeah that's what they say.

435
00:26:42,600 --> 00:26:44,800
Speaker 1: Or I'll mate with you and kill you. Right. Either way,

436
00:26:44,800 --> 00:26:46,960
Speaker 1: you're getting bit. Have you ever seen you see a

437
00:26:47,000 --> 00:26:49,280
Speaker 1: lot of them in your apartment or a house or

438
00:26:50,400 --> 00:26:54,040
Speaker 1: what do you implying? No? Well, I mean well you

439
00:26:54,040 --> 00:26:57,200
Speaker 1: don't have a basement. No, see, I go on my basement, dude.

440
00:26:57,240 --> 00:27:01,560
Speaker 1: They're everywhere. Man, it's creepy. It is creepy because you know,

441
00:27:01,880 --> 00:27:06,080
Speaker 1: they am brown reclusives, which we'll talk about too. They're

442
00:27:06,240 --> 00:27:09,480
Speaker 1: very reclusive, hence the name for the brown recluse. But

443
00:27:09,520 --> 00:27:11,240
Speaker 1: black waidows are the same. They don't want to have

444
00:27:11,280 --> 00:27:13,439
Speaker 1: anything to do with you, and when you come near them,

445
00:27:13,440 --> 00:27:16,320
Speaker 1: they want to get away from you. So having them

446
00:27:16,320 --> 00:27:18,480
Speaker 1: in your house is not really much of an issue

447
00:27:18,520 --> 00:27:21,639
Speaker 1: for you. It is for the insects in your house,

448
00:27:22,320 --> 00:27:24,879
Speaker 1: but for you it doesn't really matter. But just seeing

449
00:27:24,920 --> 00:27:27,400
Speaker 1: them and just knowing that it just makes you kind

450
00:27:27,400 --> 00:27:30,879
Speaker 1: of shudder, right. Well, that that shiny red hourglass is

451
00:27:30,920 --> 00:27:33,639
Speaker 1: just like creepy. Look they look really deadly. Yeah, and

452
00:27:33,680 --> 00:27:36,480
Speaker 1: I have an unfinished basement, so there are spiders everywhere

453
00:27:36,480 --> 00:27:39,800
Speaker 1: in my basement, dude, everywhere? Is it like the Baltimore

454
00:27:39,880 --> 00:27:44,520
Speaker 1: Wastewater treatment plant down there? It almost is like I won't, um,

455
00:27:44,560 --> 00:27:47,840
Speaker 1: I won't reach into any uh darkened area of my

456
00:27:47,880 --> 00:27:50,520
Speaker 1: basement to get a tool or something. That's probably smart

457
00:27:50,560 --> 00:27:53,120
Speaker 1: because they would want to get away from your arm.

458
00:27:53,160 --> 00:27:54,919
Speaker 1: But if you really scare them or something that they

459
00:27:54,920 --> 00:27:57,439
Speaker 1: feel threatened, they'll come at you. Like It's not like

460
00:27:57,480 --> 00:28:00,000
Speaker 1: they won't bite you, So I think that's that's very

461
00:28:00,000 --> 00:28:03,480
Speaker 1: a good chuck. I'm going to get you shoulder length

462
00:28:04,000 --> 00:28:08,120
Speaker 1: um leather gloves for Christmas. I've got some, do you yet?

463
00:28:08,200 --> 00:28:11,200
Speaker 1: Not for that, but sure you should wear them when

464
00:28:11,240 --> 00:28:13,760
Speaker 1: you go to reach of the well. I worry about

465
00:28:13,760 --> 00:28:16,720
Speaker 1: my animals sometimes, but I read that um spider venom

466
00:28:16,840 --> 00:28:18,560
Speaker 1: and we're jumping ahead a little bit, but it's not

467
00:28:19,480 --> 00:28:22,720
Speaker 1: harmful to animals. Like the most deadly spider in the

468
00:28:22,720 --> 00:28:28,439
Speaker 1: world is the funnel uh Sydney funnel weaver fun funnel

469
00:28:28,480 --> 00:28:33,840
Speaker 1: web in Australia, of course Sydney and um they I

470
00:28:33,880 --> 00:28:35,960
Speaker 1: saw a video of a cat like playing with one

471
00:28:36,560 --> 00:28:38,800
Speaker 1: and it said for some reason, it like doesn't affect

472
00:28:38,800 --> 00:28:43,000
Speaker 1: any animal, any mammal but humans. That's really weird, and

473
00:28:43,000 --> 00:28:45,240
Speaker 1: they have no idea why because humans came along way

474
00:28:45,280 --> 00:28:48,680
Speaker 1: after spiders did so then no one can figure that

475
00:28:48,720 --> 00:28:51,400
Speaker 1: part out. It's really odd. Yeah, I don't think you

476
00:28:51,400 --> 00:28:54,200
Speaker 1: have to worry about your pets with spider bites. That's

477
00:28:54,240 --> 00:28:57,160
Speaker 1: a good ps right thing. All right, So we're back

478
00:28:57,200 --> 00:29:00,720
Speaker 1: at the web. I would advise everyone at some point,

479
00:29:01,440 --> 00:29:03,120
Speaker 1: I'd like you to follow along if you're at home,

480
00:29:03,120 --> 00:29:06,920
Speaker 1: but go to the House Supports article on spiders. That

481
00:29:06,960 --> 00:29:10,680
Speaker 1: little graphic. It's so helpful. The flash animation. Yeah, yeah,

482
00:29:10,720 --> 00:29:15,200
Speaker 1: and it works not on Android devices, but it just

483
00:29:15,360 --> 00:29:17,720
Speaker 1: you just go to your desktop. Desktop version of the

484
00:29:17,760 --> 00:29:21,280
Speaker 1: site has this the little flash where you just click

485
00:29:21,360 --> 00:29:23,840
Speaker 1: next and it shows you exactly what it takes to

486
00:29:23,840 --> 00:29:25,880
Speaker 1: build a spider web. Yeah, but we'll we'll talk you

487
00:29:25,920 --> 00:29:28,440
Speaker 1: through it here. Um. The first thing that happens is

488
00:29:29,320 --> 00:29:32,120
Speaker 1: the spider gets up on someplace high up, like a

489
00:29:32,160 --> 00:29:35,680
Speaker 1: tree branch, and fires that one it's called a bridge,

490
00:29:36,240 --> 00:29:39,000
Speaker 1: that one starting point down and just hope the wind

491
00:29:39,440 --> 00:29:43,200
Speaker 1: attaches it to something else below it, and if it attaches,

492
00:29:43,600 --> 00:29:46,040
Speaker 1: then it cinches it up really tight. And he's like,

493
00:29:46,080 --> 00:29:49,200
Speaker 1: I've got this sort of like the foundation that's the baseline.

494
00:29:49,480 --> 00:29:52,920
Speaker 1: The baseline, Yeah, very nice. And uh, the spider crawls

495
00:29:52,960 --> 00:29:56,000
Speaker 1: across that baseline, which I think it's a bridge is

496
00:29:56,040 --> 00:29:59,640
Speaker 1: what it's called. Like baseline, all right. It crawls across

497
00:29:59,640 --> 00:30:02,440
Speaker 1: the base and as it does, it releases another line

498
00:30:02,440 --> 00:30:06,160
Speaker 1: of silk that's um much looser, sort of dangles below it,

499
00:30:06,240 --> 00:30:09,400
Speaker 1: and it attaches it at each end where the baseline

500
00:30:09,440 --> 00:30:12,040
Speaker 1: is attached to those two branches to right, and like

501
00:30:12,080 --> 00:30:14,040
Speaker 1: you said, it dangles below it, forming is kind of

502
00:30:14,040 --> 00:30:17,040
Speaker 1: a lazy V. And the spider crawls down to the

503
00:30:17,080 --> 00:30:19,680
Speaker 1: lowest point of that V and then drops another line

504
00:30:19,720 --> 00:30:22,040
Speaker 1: from that point down to say another anchor point, so

505
00:30:22,120 --> 00:30:25,200
Speaker 1: that forms like a tighter y. Yeah, it sort of

506
00:30:25,200 --> 00:30:28,280
Speaker 1: looks like an upside down coat hanger. If the if

507
00:30:28,320 --> 00:30:31,640
Speaker 1: the if the hook was straightened out exactly or why

508
00:30:32,120 --> 00:30:34,960
Speaker 1: you know, a why with a line crossing the two

509
00:30:35,000 --> 00:30:40,520
Speaker 1: points at top exactly. So now it's got this and again, um,

510
00:30:40,560 --> 00:30:43,600
Speaker 1: it tightens everything up along the way if everything is

511
00:30:43,600 --> 00:30:49,040
Speaker 1: going as planned, and then you have it has to

512
00:30:49,080 --> 00:30:52,400
Speaker 1: lay out frame threads and this is when it starts

513
00:30:52,680 --> 00:30:56,160
Speaker 1: going in Uh not I guess a circle, but a

514
00:30:56,160 --> 00:31:00,600
Speaker 1: circle made up of straight lines. Uh, yeah, that kind

515
00:31:00,600 --> 00:31:02,400
Speaker 1: of Yeah. I want to say octagon. But it's more

516
00:31:02,440 --> 00:31:06,720
Speaker 1: than eight sides. It's a polygon, is it. Yeah, there's

517
00:31:06,800 --> 00:31:09,680
Speaker 1: more more than one gone, so it's a polygon. I

518
00:31:09,720 --> 00:31:12,680
Speaker 1: thought poly meant five. No, No, I think that's a

519
00:31:13,320 --> 00:31:19,960
Speaker 1: I don't think so hectagon pentagon? I think so, man, no, man,

520
00:31:20,080 --> 00:31:24,320
Speaker 1: we get killed. But it's it's a it's several rhombus

521
00:31:24,360 --> 00:31:27,880
Speaker 1: is put together, all right? With that? So there's a structure.

522
00:31:27,920 --> 00:31:30,560
Speaker 1: Now there's like the outer structure, there's an inner structure.

523
00:31:30,560 --> 00:31:33,160
Speaker 1: And the thing is getting stronger and stronger, and the

524
00:31:33,240 --> 00:31:35,920
Speaker 1: spider will create um. It will start at the middle

525
00:31:35,920 --> 00:31:39,560
Speaker 1: and basically create like a circular like a Nautilus motion,

526
00:31:40,360 --> 00:31:44,120
Speaker 1: laying silk all around. Most people think of spiderwebs is

527
00:31:44,120 --> 00:31:46,640
Speaker 1: fairly sticky. It is not sticky at this point, and

528
00:31:46,720 --> 00:31:49,640
Speaker 1: for one very good reason. The spider has to move

529
00:31:49,640 --> 00:31:53,240
Speaker 1: along it, so it hasn't laid down any sticky silk yet.

530
00:31:54,440 --> 00:31:59,000
Speaker 1: But once it creates this um, this circular pattern, and

531
00:31:59,080 --> 00:32:02,280
Speaker 1: knows where it's gonna go, it goes back around it

532
00:32:02,360 --> 00:32:05,920
Speaker 1: and eats the old stuff while it lays down a silky,

533
00:32:06,320 --> 00:32:09,720
Speaker 1: sticky silk in its place. Yeah, it's it's a spiral.

534
00:32:09,760 --> 00:32:11,680
Speaker 1: We keep saying circle. I think spiral makes a little

535
00:32:11,680 --> 00:32:15,240
Speaker 1: more sense. It's the word. So yeah, like you said,

536
00:32:15,280 --> 00:32:18,880
Speaker 1: it'll it'll eat the previous one, laid down the sticky one,

537
00:32:19,120 --> 00:32:21,880
Speaker 1: but it also still has an auxiliary spiral to get

538
00:32:21,880 --> 00:32:25,280
Speaker 1: around on. It just knows where to walk basically, Yeah,

539
00:32:25,360 --> 00:32:26,840
Speaker 1: like I'm not gonna walk on the sticky one. I'm

540
00:32:26,840 --> 00:32:28,600
Speaker 1: gonna walk on the other one. Right. It was pretty

541
00:32:28,600 --> 00:32:31,480
Speaker 1: amazing in itself. Yeah, and then it's web is is

542
00:32:31,600 --> 00:32:34,720
Speaker 1: created and that's again it's called an orb web. A

543
00:32:34,760 --> 00:32:38,040
Speaker 1: lot of spiders and it's mostly from garden spiders that

544
00:32:38,120 --> 00:32:43,480
Speaker 1: create orb webs in an elevated area. Beautiful. Um, Charlotte

545
00:32:44,400 --> 00:32:46,600
Speaker 1: must have been a garden spider and it's clearly an

546
00:32:46,680 --> 00:32:49,080
Speaker 1: orb web. The thing definitely have more than a hundred

547
00:32:49,080 --> 00:32:52,160
Speaker 1: thousand neurons because it could spell Yeah. We had a

548
00:32:52,200 --> 00:32:56,360
Speaker 1: big garden spider um we've won last year on our

549
00:32:56,400 --> 00:33:00,280
Speaker 1: side deck attaching to our house and was in a

550
00:33:00,320 --> 00:33:02,280
Speaker 1: great place that the dogs wouldn't hit it and we

551
00:33:02,280 --> 00:33:04,160
Speaker 1: wouldn't hit it, and we would just go out every

552
00:33:04,240 --> 00:33:05,680
Speaker 1: day and be like, you know, check it out and

553
00:33:05,680 --> 00:33:07,760
Speaker 1: see how it was doing. How was it doing. It

554
00:33:07,880 --> 00:33:10,280
Speaker 1: was doing great lots of lots of flies and stuff,

555
00:33:10,280 --> 00:33:14,040
Speaker 1: and it was fattening up while they're not there for long. Yeah. Um,

556
00:33:14,240 --> 00:33:16,240
Speaker 1: So generally they'll hang out in the middle of that

557
00:33:16,320 --> 00:33:19,880
Speaker 1: web wait for the vibrations. And like we said, they

558
00:33:19,880 --> 00:33:23,680
Speaker 1: can even tell the difference between like a wasp getting caught,

559
00:33:24,000 --> 00:33:28,880
Speaker 1: which is not so great sometimes, or uh, butterfly, let's say,

560
00:33:29,760 --> 00:33:32,200
Speaker 1: and which they want to eat. So they love butterfly

561
00:33:32,600 --> 00:33:37,040
Speaker 1: delicious flight tastes like frog legs to them. Uh. Some

562
00:33:37,160 --> 00:33:39,320
Speaker 1: other spiders will be like, I'm not waiting in the

563
00:33:39,320 --> 00:33:42,440
Speaker 1: middle of this web. It's raining out. I'm gonna go

564
00:33:42,480 --> 00:33:45,040
Speaker 1: hang out in my nest. And they'll they'll leave like

565
00:33:45,120 --> 00:33:48,240
Speaker 1: a drag line that in this case is considered a

566
00:33:48,320 --> 00:33:51,160
Speaker 1: signal line, and it's just attached to the web. So

567
00:33:51,200 --> 00:33:55,520
Speaker 1: they're looking for signals like vibrations from the web. Yeah.

568
00:33:55,560 --> 00:33:59,640
Speaker 1: It's like, uh, it's like being the laziest fisherman, the

569
00:33:59,640 --> 00:34:01,920
Speaker 1: one that just throws out the thing with the bomber

570
00:34:02,880 --> 00:34:05,520
Speaker 1: and then just start drinking beer and reading their outdoor

571
00:34:05,800 --> 00:34:09,880
Speaker 1: readers readers digests, and then when they feel something, they're like,

572
00:34:09,880 --> 00:34:14,400
Speaker 1: oh man, i'm fishing exactly. Yeah, it's that kind of spider.

573
00:34:15,239 --> 00:34:17,360
Speaker 1: Uh here's the other neat thing. When a web is

574
00:34:17,400 --> 00:34:21,520
Speaker 1: no longer useful, many times the spider will eat it

575
00:34:21,680 --> 00:34:26,240
Speaker 1: and recycle that silk. Yeah, which is amazing. It breaks

576
00:34:26,280 --> 00:34:28,719
Speaker 1: down the proteins and it uses it again later. Yeah,

577
00:34:28,760 --> 00:34:32,239
Speaker 1: a little recyclers. Pretty smart things. All right, Well, let's

578
00:34:32,280 --> 00:34:34,399
Speaker 1: take our final break here and then we will talk

579
00:34:34,440 --> 00:34:38,440
Speaker 1: about some other hunting methods that spiders use right after this.

580
00:34:55,480 --> 00:34:58,040
Speaker 1: All right, so we're back and we're talking about other

581
00:34:58,400 --> 00:35:02,319
Speaker 1: hunting methods. Um As, I said, this great documentary I

582
00:35:02,360 --> 00:35:05,680
Speaker 1: watched said that spiders or some of the maybe the

583
00:35:05,719 --> 00:35:10,560
Speaker 1: best most efficient, fully realized predator on the planet. Dude,

584
00:35:10,960 --> 00:35:13,920
Speaker 1: like as well as a shark. Yeah, as good as

585
00:35:13,960 --> 00:35:16,520
Speaker 1: a shark. Spider would kill a shark in a second,

586
00:35:16,840 --> 00:35:19,120
Speaker 1: that he was the size of a shark. You might, definitely.

587
00:35:22,000 --> 00:35:23,400
Speaker 1: And by the way we did our little p s

588
00:35:23,440 --> 00:35:26,319
Speaker 1: a with snakes, you shouldn't kill spiders either, or no,

589
00:35:26,440 --> 00:35:28,560
Speaker 1: I mean, like you want to leave them around because

590
00:35:28,600 --> 00:35:30,480
Speaker 1: they're like taking care of a lot of pests that

591
00:35:30,560 --> 00:35:33,840
Speaker 1: you don't want. I talked about mosquitoes. I hate mosquitoes.

592
00:35:34,160 --> 00:35:37,680
Speaker 1: Who doesn't. I'll kill a mosquito. So a spider will

593
00:35:37,719 --> 00:35:40,400
Speaker 1: eat a mosquito in a second. It's like frog legs

594
00:35:40,400 --> 00:35:46,520
Speaker 1: to them. Again, nothing but rock legs. Uh. So let's

595
00:35:46,520 --> 00:35:50,000
Speaker 1: talk about some of the other ways that spiders can hunt. Um,

596
00:35:50,080 --> 00:35:53,399
Speaker 1: some have venom, Like they're waiting a little trap door

597
00:35:54,000 --> 00:35:55,600
Speaker 1: that they've made a little hole in the ground. They

598
00:35:55,600 --> 00:35:58,000
Speaker 1: build a little web web door on a hinge like

599
00:35:58,040 --> 00:36:00,799
Speaker 1: a tiger pit, and they'll jump out and you can

600
00:36:00,840 --> 00:36:03,000
Speaker 1: see video of this online too, or they'll let you

601
00:36:03,040 --> 00:36:05,400
Speaker 1: fall into the hole and then they're on you. Like

602
00:36:05,440 --> 00:36:10,400
Speaker 1: that snake. Yeah, this tarantula ate a viper man. That's crazy.

603
00:36:10,560 --> 00:36:12,120
Speaker 1: And when I say ate, it like it's not like

604
00:36:12,160 --> 00:36:15,560
Speaker 1: a snake eat something and it's just not there anymore. Like, uh,

605
00:36:15,719 --> 00:36:18,080
Speaker 1: you know, it sucked out whatever it could eat from

606
00:36:18,120 --> 00:36:22,440
Speaker 1: the snake after paralyzing it with its venom, which is

607
00:36:22,480 --> 00:36:26,560
Speaker 1: where we are. Um. Wolf spiders, Yeah, they're land spider.

608
00:36:26,680 --> 00:36:28,920
Speaker 1: They don't hunt with the web. They stalk their prey.

609
00:36:29,360 --> 00:36:33,560
Speaker 1: Uh huh yeah, which is terrifying. Yeah, jumping spiders do

610
00:36:33,640 --> 00:36:37,480
Speaker 1: that too. Yeah. The difference, So jumping spiders stalk their

611
00:36:37,520 --> 00:36:39,879
Speaker 1: prey kind of like a cat. But when a cat

612
00:36:40,280 --> 00:36:43,799
Speaker 1: is ready to pounce, it will pounce and run. A

613
00:36:43,920 --> 00:36:47,520
Speaker 1: jumping spider just pounces and it lands to work. Yeah,

614
00:36:47,560 --> 00:36:52,080
Speaker 1: and your toast. You ever seen the wolf spider when

615
00:36:52,320 --> 00:36:56,160
Speaker 1: it has all the babies on its back, No jump

616
00:36:56,200 --> 00:36:58,840
Speaker 1: off and run around. That's something that I think is

617
00:36:59,160 --> 00:37:02,160
Speaker 1: is worth meant in here. Yeah, it's terrifying. So you said,

618
00:37:02,160 --> 00:37:05,520
Speaker 1: a lot of a lot of spiders. Um, a lot

619
00:37:05,600 --> 00:37:09,760
Speaker 1: of spiders will create like a cocoon for their spider

620
00:37:09,840 --> 00:37:13,879
Speaker 1: lyings with silk, and a lot of spider species will

621
00:37:13,920 --> 00:37:16,919
Speaker 1: just like there you go, kids, you're have a good life,

622
00:37:17,200 --> 00:37:20,000
Speaker 1: and the spider mom goes off. Wolf spiders carry their

623
00:37:20,040 --> 00:37:23,120
Speaker 1: cocoons around with them and then, like you're saying, even

624
00:37:23,200 --> 00:37:27,279
Speaker 1: after the spiderlings hatch, the spiderlings just hit your ride

625
00:37:27,320 --> 00:37:29,920
Speaker 1: on the back of their mom for a while until

626
00:37:29,960 --> 00:37:32,360
Speaker 1: they're old enough to start taking care of themselves, and

627
00:37:32,360 --> 00:37:35,640
Speaker 1: then they spread out, which is really unusual for spiders

628
00:37:35,680 --> 00:37:38,680
Speaker 1: as far as reproduction goes. It's crazy looking. I've seen

629
00:37:38,680 --> 00:37:41,160
Speaker 1: wolf spiders that, um maybe it was a noise that

630
00:37:41,239 --> 00:37:43,279
Speaker 1: frightened them or something, but all of a sudden they're

631
00:37:43,360 --> 00:37:48,799
Speaker 1: you know, did you see uh that vine that that

632
00:37:48,920 --> 00:37:51,600
Speaker 1: dude posted from Mexico and the beginning of two thousand

633
00:37:51,640 --> 00:37:53,600
Speaker 1: and fourteen that became really famous. It looks like a

634
00:37:54,000 --> 00:37:57,040
Speaker 1: little to pay on like a blue plastic bin. I

635
00:37:57,040 --> 00:37:59,000
Speaker 1: don't like where this is going. And he goes up

636
00:37:59,040 --> 00:38:01,399
Speaker 1: in like poke, and all of a sudden, the two

637
00:38:01,400 --> 00:38:05,200
Speaker 1: pages turns into about ten thousand spiders. But it's not

638
00:38:05,200 --> 00:38:09,480
Speaker 1: actually spiders. They're harvestment like Daddy long legs. Daddy long

639
00:38:09,560 --> 00:38:14,160
Speaker 1: legs aren't actually spiders there arachnids. Oh, is that the deal? Um?

640
00:38:14,200 --> 00:38:16,719
Speaker 1: And one of the things that differentiates them is this

641
00:38:16,960 --> 00:38:22,120
Speaker 1: packing clumping um instinct that they'll four. It looks like

642
00:38:22,160 --> 00:38:24,440
Speaker 1: just this bad tube page just sitting there, but it's

643
00:38:24,480 --> 00:38:27,239
Speaker 1: really a bunch of spiders or a bunch of harvestment

644
00:38:28,160 --> 00:38:31,600
Speaker 1: and what no terrible toothpage. And what they're doing is, um,

645
00:38:31,640 --> 00:38:34,920
Speaker 1: they're maintaining moisture in like a hot, dry environment by

646
00:38:34,920 --> 00:38:38,120
Speaker 1: by clumping together and kind of pooling their moisture. And

647
00:38:38,239 --> 00:38:40,960
Speaker 1: then as the sun goes down, they'll like spread out again.

648
00:38:41,239 --> 00:38:42,719
Speaker 1: But if you go up and touch them like this

649
00:38:42,760 --> 00:38:44,919
Speaker 1: guy did on vine so it's just like this ninth

650
00:38:44,920 --> 00:38:49,200
Speaker 1: second loop over and over again. Um, they just separate

651
00:38:49,239 --> 00:38:52,120
Speaker 1: and scatter everywhere. It's pretty neat. Have you done it?

652
00:38:52,200 --> 00:38:55,080
Speaker 1: Don't be dumb on the Granddaddy long Legs supposedly being

653
00:38:55,080 --> 00:38:58,319
Speaker 1: the most poisonous. I looked into it. No, I kind

654
00:38:58,320 --> 00:39:02,839
Speaker 1: of ran into a wall because it's like, so this

655
00:39:02,880 --> 00:39:07,759
Speaker 1: is what I found. Yes, that they they the old

656
00:39:07,760 --> 00:39:10,200
Speaker 1: wives tale is that they are the most poisonous around,

657
00:39:10,280 --> 00:39:13,200
Speaker 1: but their mouths are too small to puncture human skin.

658
00:39:13,760 --> 00:39:15,680
Speaker 1: But if they could, they could kill you. I don't

659
00:39:15,719 --> 00:39:18,680
Speaker 1: believe that. So if it's a harvestman, that's and apparently

660
00:39:18,680 --> 00:39:22,160
Speaker 1: there's a bunch of different arachnids that are called Granddaddy

661
00:39:22,200 --> 00:39:25,400
Speaker 1: long legs. But if it's the harvestman, then it's completely

662
00:39:25,440 --> 00:39:27,719
Speaker 1: false because not only do they not have venom, they

663
00:39:27,719 --> 00:39:30,880
Speaker 1: don't even have fangs because they couldn't bite you. But

664
00:39:30,960 --> 00:39:33,480
Speaker 1: another caveat to that is is that although they can

665
00:39:33,520 --> 00:39:36,120
Speaker 1: survive if like they lose a leg, and this is

666
00:39:36,120 --> 00:39:38,640
Speaker 1: an adaptation to where like, if a predator has their leg,

667
00:39:39,000 --> 00:39:41,480
Speaker 1: they'll just pull it off themselves and run off. And

668
00:39:41,520 --> 00:39:44,800
Speaker 1: the guy's like, oh man, they can't regrow their legs.

669
00:39:45,360 --> 00:39:48,279
Speaker 1: They can survive without them, they can't regrow them, so

670
00:39:48,320 --> 00:39:51,080
Speaker 1: they'll have like just whatever seven legs. Yes, so you

671
00:39:51,080 --> 00:39:53,200
Speaker 1: don't want to pull the legs off a granddaddy long

672
00:39:53,280 --> 00:39:55,719
Speaker 1: legs because it's not growing back. Kids. Yeah, it's not

673
00:39:55,840 --> 00:39:59,360
Speaker 1: cool to do. Yeah, the torture insects. Don't listen to Ricky,

674
00:39:59,440 --> 00:40:01,880
Speaker 1: your Billy, you're Tommy or whoever is telling you that

675
00:40:01,920 --> 00:40:07,960
Speaker 1: their legs are going to grow back. Now, they're going nowhere, nowhere. Um,

676
00:40:07,960 --> 00:40:11,839
Speaker 1: all right, So we were talking about venom. Um. Most

677
00:40:11,880 --> 00:40:15,760
Speaker 1: spiders have pretty much the same procedure when killing prey.

678
00:40:16,600 --> 00:40:21,480
Speaker 1: They have um. The weapon is these a pair of

679
00:40:21,560 --> 00:40:26,640
Speaker 1: jointed jaws called calorisari. I think, are you're gonna go

680
00:40:26,680 --> 00:40:33,919
Speaker 1: with that? I'm going with cellisari? All right? Um? Cellisari, calorisari,

681
00:40:34,680 --> 00:40:39,520
Speaker 1: cellis celli Sara Man. Some people like this stuff. Some

682
00:40:39,560 --> 00:40:42,000
Speaker 1: people think it's some people are like, I'm done with

683
00:40:42,040 --> 00:40:45,040
Speaker 1: these guys forever. But each part of this jaw has

684
00:40:45,080 --> 00:40:47,359
Speaker 1: two parts of the basil segment, which is the bulk

685
00:40:47,400 --> 00:40:51,040
Speaker 1: of it, and then these fangs, and just like snakes,

686
00:40:51,719 --> 00:40:56,000
Speaker 1: these fangs act as little needles, and they have a

687
00:40:56,080 --> 00:40:59,120
Speaker 1: venom duct that they'll squeeze the venom through the fang,

688
00:40:59,680 --> 00:41:02,400
Speaker 1: just a snake. Yeah, it's pretty remarkable, and the venom

689
00:41:02,640 --> 00:41:06,960
Speaker 1: is very frequently a neurotoxin. Paralyzes the prey like a snake,

690
00:41:08,080 --> 00:41:11,640
Speaker 1: and then um, I think you're really funky with the

691
00:41:11,880 --> 00:41:15,400
Speaker 1: spider after that point. So it's it's taken down a mouse,

692
00:41:15,680 --> 00:41:18,919
Speaker 1: it's paralyzed it. The mouse is like, oh god, I'm

693
00:41:18,960 --> 00:41:22,520
Speaker 1: locked in. I can experience everything, but I can't move.

694
00:41:23,040 --> 00:41:25,600
Speaker 1: And this is horrible because now I'm being killed by

695
00:41:25,600 --> 00:41:30,279
Speaker 1: a spider. It's like the anesthesia awareness exactly, you know,

696
00:41:30,440 --> 00:41:33,000
Speaker 1: but even worse than that. But there's not a doctor.

697
00:41:33,040 --> 00:41:36,520
Speaker 1: It's a spider. You're being operated on by a spider,

698
00:41:38,440 --> 00:41:41,319
Speaker 1: and um, the spider is now injecting you know that

699
00:41:41,320 --> 00:41:45,560
Speaker 1: you're paralyzed. Now it's injecting you with digestive enzymes, and

700
00:41:45,680 --> 00:41:48,719
Speaker 1: you will be liquefied from the inside out because, like

701
00:41:48,760 --> 00:41:52,680
Speaker 1: we said, spiders eat nothing but soup essentially, yeah, their

702
00:41:52,800 --> 00:41:56,160
Speaker 1: entire life. But the soup that they eat doesn't start

703
00:41:56,160 --> 00:41:59,959
Speaker 1: out as a soup. Instead, it starts out as must

704
00:42:00,000 --> 00:42:02,640
Speaker 1: will in tissue and all that kind of stuff inside

705
00:42:02,680 --> 00:42:05,480
Speaker 1: a mouse, and then once it liquefies, the spider will

706
00:42:05,480 --> 00:42:07,759
Speaker 1: suck all that stuff out and then that's its food

707
00:42:07,760 --> 00:42:12,000
Speaker 1: and it takes like frog legs to it. The actual

708
00:42:12,160 --> 00:42:14,759
Speaker 1: fangs themselves, Um can work a couple of different ways.

709
00:42:14,800 --> 00:42:18,000
Speaker 1: In the case of a tarantulas, um, it works like

710
00:42:18,040 --> 00:42:23,360
Speaker 1: an axe the fangs swing down, and uh Irannium morphs,

711
00:42:23,400 --> 00:42:26,360
Speaker 1: which are the most dominant suborder, they act as little pinchers,

712
00:42:26,960 --> 00:42:30,759
Speaker 1: which is better, Yeah, because I think the tarantules need

713
00:42:30,760 --> 00:42:33,680
Speaker 1: to actually pin something against something to swing those little

714
00:42:33,760 --> 00:42:37,200
Speaker 1: fang axes down. Yeah, Whereas if you're an rannium morph like,

715
00:42:37,280 --> 00:42:40,920
Speaker 1: your pinchers are just using the pressure created by the

716
00:42:40,960 --> 00:42:45,960
Speaker 1: other pincher to puncture right your prey. So what does

717
00:42:45,960 --> 00:42:48,920
Speaker 1: this mean for us? Dude, you get bit by a

718
00:42:48,960 --> 00:42:54,719
Speaker 1: spider venomous spider, are you going to die? Uh? No,

719
00:42:55,200 --> 00:42:59,160
Speaker 1: the chances are pretty high that you're not going to

720
00:42:59,200 --> 00:43:01,959
Speaker 1: die as in a healthy adult human. Yeah. I think

721
00:43:02,040 --> 00:43:06,359
Speaker 1: that the across the entire world, the morbidity rate of

722
00:43:06,560 --> 00:43:10,279
Speaker 1: a spider bite is like ten. But even for ones

723
00:43:10,320 --> 00:43:13,720
Speaker 1: that we think are so deadly, like um, the brown

724
00:43:13,760 --> 00:43:18,319
Speaker 1: recluse spider, morbidity rates were at five percent before we

725
00:43:18,440 --> 00:43:22,400
Speaker 1: discovered an evenin so I'm gonna feel good. No, And

726
00:43:22,440 --> 00:43:26,719
Speaker 1: there's actually some nasty, nasty videos on YouTube. There's a

727
00:43:26,760 --> 00:43:30,160
Speaker 1: guy the video the worst one. He basically created a

728
00:43:30,239 --> 00:43:34,160
Speaker 1: video diary of like him just filming his foot with

729
00:43:34,320 --> 00:43:38,200
Speaker 1: the brown recluse bite and just talking about like how

730
00:43:38,320 --> 00:43:41,440
Speaker 1: nasty it is, and he stopped because he thought no

731
00:43:41,480 --> 00:43:44,160
Speaker 1: one wanted to see it. And everybody's like, where's more videos?

732
00:43:44,239 --> 00:43:46,520
Speaker 1: What's going on now? So we started like posting him

733
00:43:46,520 --> 00:43:50,480
Speaker 1: all the time. But I think it says um brown

734
00:43:50,520 --> 00:43:57,600
Speaker 1: recluse spider bite disturbing video. After three months, put those

735
00:43:57,640 --> 00:43:59,840
Speaker 1: words into YouTube and it will bring up this dude's

736
00:44:00,520 --> 00:44:03,680
Speaker 1: foot and it looks like a giant cabbage patch kid

737
00:44:04,640 --> 00:44:07,200
Speaker 1: and there's a it looks like have you ever seen

738
00:44:07,320 --> 00:44:10,239
Speaker 1: um Requiem for a Dream? Remember the end where he's

739
00:44:10,239 --> 00:44:13,640
Speaker 1: got that mess that on the top of a cabbage

740
00:44:13,640 --> 00:44:18,200
Speaker 1: patch kid's foot And people wanted more, more, more, Yeah,

741
00:44:18,239 --> 00:44:21,000
Speaker 1: which proves my theory that the internet is thunder dumb.

742
00:44:21,120 --> 00:44:24,000
Speaker 1: But this guy is like it's so gross, like you

743
00:44:24,040 --> 00:44:28,080
Speaker 1: could easily fit two fingers into this spider bite. And

744
00:44:28,120 --> 00:44:31,480
Speaker 1: the reason why is because this guy's suffered necrosis, which

745
00:44:31,520 --> 00:44:35,520
Speaker 1: is a a side effect of the brown recluses toxins

746
00:44:36,480 --> 00:44:40,239
Speaker 1: uh and if untreated, you're probably again you're not gonna die,

747
00:44:40,400 --> 00:44:42,680
Speaker 1: it's gonna hurt like crazy. He was going to a

748
00:44:42,680 --> 00:44:44,600
Speaker 1: doctor through all this though, right, Yeah, he had to.

749
00:44:45,200 --> 00:44:48,040
Speaker 1: You'd have to be just totally psychotic to have your

750
00:44:48,040 --> 00:44:50,799
Speaker 1: foot look like this and not go seek medical. It's

751
00:44:50,800 --> 00:44:55,279
Speaker 1: looking better today Thursday. Yeah. Um, but the the the

752
00:44:55,520 --> 00:44:59,480
Speaker 1: you can suffer severe like scarring and tissue damage, but

753
00:44:59,560 --> 00:45:02,960
Speaker 1: you're probably dobably not gonna die. But it hurts because

754
00:45:03,040 --> 00:45:07,840
Speaker 1: they affect our ion channels, right yeah. Um. Kristen Conger,

755
00:45:07,960 --> 00:45:10,319
Speaker 1: I think had wrote a great side article about how

756
00:45:10,600 --> 00:45:14,480
Speaker 1: um deadly spiders work, on how stuff works, and for

757
00:45:14,520 --> 00:45:17,480
Speaker 1: instance that the Sydney funnel web venom it's a delta

758
00:45:18,080 --> 00:45:22,920
Speaker 1: um atrocotoxin and it is an amino acid chain that

759
00:45:23,239 --> 00:45:28,080
Speaker 1: uh causes damage to nerve cells. Yeah, it makes our

760
00:45:28,160 --> 00:45:33,719
Speaker 1: nerves cells like fire, uh excitedly, like constantly. I think

761
00:45:33,719 --> 00:45:37,480
Speaker 1: it's I think some toxins, when they affect our nerve cells,

762
00:45:37,719 --> 00:45:39,840
Speaker 1: it just makes them fire over and over and over again,

763
00:45:40,280 --> 00:45:44,800
Speaker 1: which affects their performance. It's not what you want. And uh,

764
00:45:44,880 --> 00:45:50,080
Speaker 1: as far as no susceptor cells, you are just experiencing

765
00:45:50,120 --> 00:45:54,160
Speaker 1: tremendous amounts of pain. Right or before nineteen eighty when

766
00:45:54,160 --> 00:45:57,440
Speaker 1: they discovered the funnel web anti vennon, you could die

767
00:45:57,520 --> 00:45:59,920
Speaker 1: from it. But since then they say no one has

768
00:46:00,040 --> 00:46:03,680
Speaker 1: died from it. No, and the the funnel web. This

769
00:46:03,760 --> 00:46:06,520
Speaker 1: is the one that's routinely pointed out as the world's

770
00:46:06,640 --> 00:46:11,080
Speaker 1: deadliest spider, although Kristen points out there's no real scientific

771
00:46:11,120 --> 00:46:15,319
Speaker 1: consensus on that because there's not that many spiders that

772
00:46:15,400 --> 00:46:19,680
Speaker 1: really even have a chance to be considered deadly to humans. Um.

773
00:46:19,719 --> 00:46:22,279
Speaker 1: But the funnel the Sydney funnel web, which lives in

774
00:46:22,280 --> 00:46:26,399
Speaker 1: the mile radius around Sydney, Australia, right in the city right,

775
00:46:26,719 --> 00:46:31,800
Speaker 1: Um is is I guess if you really pressed uh science, science,

776
00:46:32,120 --> 00:46:37,759
Speaker 1: almost said scientologists, he pressed a spider researcher, Um, they

777
00:46:37,760 --> 00:46:39,719
Speaker 1: would probably say the Sydney funnel Web. And one of

778
00:46:39,760 --> 00:46:43,480
Speaker 1: the reasons why is because it's fangs, it's pincers can

779
00:46:43,680 --> 00:46:49,160
Speaker 1: pierce human toenail. Yeah, and they're aggressive, like if you

780
00:46:49,200 --> 00:46:51,000
Speaker 1: want to get out of here, they may not get

781
00:46:51,040 --> 00:46:53,760
Speaker 1: out of there. They may say, oh, yeah, I'm coming. Yeah,

782
00:46:53,920 --> 00:46:56,960
Speaker 1: they like eat a can of spinach and come at you. Scary.

783
00:46:57,640 --> 00:47:00,000
Speaker 1: I think there's one in Brazil too, called the wandering

784
00:47:00,120 --> 00:47:04,120
Speaker 1: spider Brazilian wandering and it is um has been cited

785
00:47:04,160 --> 00:47:07,440
Speaker 1: as the deadliest as well because it can inject up

786
00:47:07,480 --> 00:47:09,880
Speaker 1: to two milligrams of venom, which is just that's a

787
00:47:09,920 --> 00:47:13,640
Speaker 1: lot of venom for a spider. So it is a

788
00:47:13,680 --> 00:47:16,120
Speaker 1: hunting spider as well, and it is also aggressive. So

789
00:47:16,160 --> 00:47:20,319
Speaker 1: I'm glad that most venomous are the most aggressive. Yeah,

790
00:47:20,360 --> 00:47:23,360
Speaker 1: it's fine how that works out. Uh, so how do

791
00:47:23,440 --> 00:47:27,000
Speaker 1: we get spiders, chuck, Where do they come from? Well?

792
00:47:27,200 --> 00:47:30,840
Speaker 1: They they have sex, Yes, they do. Spider sex is

793
00:47:30,880 --> 00:47:36,160
Speaker 1: pretty fascinating. Not as interesting as snake sex. Maybe maybe

794
00:47:36,160 --> 00:47:40,000
Speaker 1: it is. I no, no, I don't think so let's

795
00:47:40,000 --> 00:47:43,480
Speaker 1: talk about it. Okay, So what we said that spiders

796
00:47:43,800 --> 00:47:47,719
Speaker 1: are almost exclusively solitary hunters. Yeah, they don't hang out

797
00:47:47,719 --> 00:47:50,120
Speaker 1: with their families. So if you're a male and you're like,

798
00:47:50,160 --> 00:47:54,239
Speaker 1: I gotta reproduce, I gotta pass these jeans along. Um,

799
00:47:54,360 --> 00:47:57,439
Speaker 1: you're going to seek out a female spider. But it's

800
00:47:57,480 --> 00:47:59,920
Speaker 1: not the easiest thing in the world to do. Now,

801
00:48:00,080 --> 00:48:01,640
Speaker 1: only do you have to find a female spider, you

802
00:48:01,640 --> 00:48:06,160
Speaker 1: have to find one of reproductive age and ready to reproduce. Yeah,

803
00:48:06,160 --> 00:48:08,480
Speaker 1: and not eat you. But that's a big that's a

804
00:48:08,480 --> 00:48:10,600
Speaker 1: big point. But in the case of the black widow,

805
00:48:10,640 --> 00:48:15,320
Speaker 1: you're gonna get eaten anyway. But um, females are way

806
00:48:15,400 --> 00:48:18,400
Speaker 1: bigger than the males, which is one way that males

807
00:48:18,440 --> 00:48:20,399
Speaker 1: get eaten. Yeah. I saw a video of a black

808
00:48:20,440 --> 00:48:24,080
Speaker 1: widows mating and it looked like a little baby spider

809
00:48:24,560 --> 00:48:27,120
Speaker 1: trying to mate with a big, big spider. But it's

810
00:48:27,160 --> 00:48:30,320
Speaker 1: just a male and a female, so they the female

811
00:48:30,360 --> 00:48:33,440
Speaker 1: when it decides. All right, I guess I have to

812
00:48:33,480 --> 00:48:36,120
Speaker 1: do this. I have to be defiled. I'm gonna lay

813
00:48:36,160 --> 00:48:38,200
Speaker 1: down a drag line sort of like a snake does,

814
00:48:38,320 --> 00:48:41,719
Speaker 1: covered in pheromones wherever I go. I'm just gonna leave

815
00:48:41,760 --> 00:48:44,200
Speaker 1: this scented trail behind me on this drag line. Or

816
00:48:44,239 --> 00:48:47,680
Speaker 1: if it's a web based spider, they may lay pheromones

817
00:48:47,719 --> 00:48:50,560
Speaker 1: over the web right and just let the wind do

818
00:48:50,600 --> 00:48:53,120
Speaker 1: its work. Yeah. Either way, these spiders are going to

819
00:48:53,200 --> 00:48:57,080
Speaker 1: pick up on us and be like, Okay, I'm heading

820
00:48:57,120 --> 00:48:59,600
Speaker 1: that direction. Yeah, I'm gonna follow this drag line. Who's

821
00:48:59,719 --> 00:49:02,480
Speaker 1: pull a little self down this drag line and finally

822
00:49:03,160 --> 00:49:06,879
Speaker 1: I get to the female. Uh. Although we should point

823
00:49:06,880 --> 00:49:10,560
Speaker 1: out another creepy thing that spiders will do is they're

824
00:49:10,600 --> 00:49:13,840
Speaker 1: so desperate to mate that they'll hang around females that

825
00:49:13,880 --> 00:49:17,240
Speaker 1: are too young until they get to the right age,

826
00:49:17,280 --> 00:49:20,120
Speaker 1: Like they'll hang around the playground and it's so creepy

827
00:49:20,120 --> 00:49:23,839
Speaker 1: and predatory. They'll be like, oh, she's she's close. Let

828
00:49:23,920 --> 00:49:26,719
Speaker 1: me wait a few weeks. So yeah, they're like, I

829
00:49:26,719 --> 00:49:32,200
Speaker 1: don't feel like searching. I'm just gonna wait. So, um,

830
00:49:32,280 --> 00:49:35,680
Speaker 1: when when they find the female, that's just step one.

831
00:49:36,000 --> 00:49:38,200
Speaker 1: Step two is convincing her that you're not in dinner

832
00:49:39,120 --> 00:49:42,080
Speaker 1: and that you're not trying to encroach on your territory. Right,

833
00:49:42,160 --> 00:49:44,960
Speaker 1: You're like, I just wanted mate. Uh. And there's some

834
00:49:45,040 --> 00:49:46,920
Speaker 1: different ways that spiders do this. So, like with a

835
00:49:47,000 --> 00:49:50,759
Speaker 1: jumping spider and species that have like good vision, they

836
00:49:50,800 --> 00:49:54,359
Speaker 1: may do a little dance, Yeah, a little look at me,

837
00:49:55,040 --> 00:49:58,480
Speaker 1: look at me over here. Yeah, well spiders will do that. Uh.

838
00:49:58,520 --> 00:50:01,279
Speaker 1: And then spiders again that are web based, the male

839
00:50:01,360 --> 00:50:03,800
Speaker 1: may come up and like play a little a little

840
00:50:03,880 --> 00:50:07,359
Speaker 1: tune on the web. Yeah, like plucking a guitar string,

841
00:50:07,440 --> 00:50:11,000
Speaker 1: exactly for the female to be like, oh, I see

842
00:50:11,040 --> 00:50:14,879
Speaker 1: what you're after. She's like, is that Jose Feliciano. I'm

843
00:50:14,920 --> 00:50:18,600
Speaker 1: such a sucker for Jose Feliciano. So once they have

844
00:50:18,800 --> 00:50:23,120
Speaker 1: convinced the female spider that they are there to have

845
00:50:23,200 --> 00:50:26,680
Speaker 1: some fun, they're not food, they're not a threat. They

846
00:50:26,719 --> 00:50:29,720
Speaker 1: like the tune of my guitar or the way I dance.

847
00:50:30,520 --> 00:50:32,560
Speaker 1: There's a lot of work that goes into it. The

848
00:50:32,600 --> 00:50:35,680
Speaker 1: female finally is like, all right, well, let me just

849
00:50:36,520 --> 00:50:39,480
Speaker 1: get into position here and send you the right signal

850
00:50:39,680 --> 00:50:43,120
Speaker 1: that I'm ready to go. And I might shake my

851
00:50:43,200 --> 00:50:45,800
Speaker 1: web or something um if I don't like you, or

852
00:50:45,800 --> 00:50:49,480
Speaker 1: I might just crawl away, but otherwise here I am. Um,

853
00:50:49,600 --> 00:50:52,440
Speaker 1: let's do this right. And so, like any other animal

854
00:50:52,719 --> 00:50:57,400
Speaker 1: on the planet, they copulate by putting their reproductive organs together.

855
00:50:57,960 --> 00:51:02,279
Speaker 1: They don't couple. What you're being awaite, they don't couple

856
00:51:02,360 --> 00:51:06,320
Speaker 1: like snakes even do. Um. The male deposits sperm onto

857
00:51:06,360 --> 00:51:10,080
Speaker 1: a little web and then picks it up. It's basically

858
00:51:10,160 --> 00:51:15,200
Speaker 1: like ivf yes, but with um petted palps the little

859
00:51:15,200 --> 00:51:19,120
Speaker 1: forearms that the spider has. Yeah, he deposits that sperm

860
00:51:19,239 --> 00:51:22,680
Speaker 1: onto the general opening of the female, and I guess

861
00:51:22,760 --> 00:51:25,880
Speaker 1: the female stores it there near the ovaries. Yeah. She's like,

862
00:51:25,960 --> 00:51:29,120
Speaker 1: smell you later. Yeah, if he's lucky. If he's not lucky,

863
00:51:29,160 --> 00:51:32,319
Speaker 1: she turns around and eats him afterwards, right, which the

864
00:51:32,320 --> 00:51:33,960
Speaker 1: male spider is fine with because all it wants to

865
00:51:34,000 --> 00:51:36,960
Speaker 1: do is reproduce. But then at some point later on,

866
00:51:37,040 --> 00:51:39,279
Speaker 1: the female will be like, oh, yeah, that's right, I've

867
00:51:39,280 --> 00:51:42,880
Speaker 1: got that sperm stored away. I'll fertilize these eggs and

868
00:51:42,960 --> 00:51:45,680
Speaker 1: there you have it. Yeah. And then they lay like

869
00:51:45,719 --> 00:51:49,360
Speaker 1: we said, either um, hundreds or thousands of eggs in

870
00:51:49,480 --> 00:51:52,440
Speaker 1: one go. And they may encase them like we said.

871
00:51:52,480 --> 00:51:55,920
Speaker 1: They may carry him around, they may abandon the eggs

872
00:51:56,040 --> 00:51:59,920
Speaker 1: entirely and just say good luck. What's crazy to me? Spiders?

873
00:52:00,120 --> 00:52:05,800
Speaker 1: So they live, um, months, up to years. Apparently tarantulas

874
00:52:05,840 --> 00:52:08,320
Speaker 1: can live up to twenty years, like a pet tarantula.

875
00:52:08,560 --> 00:52:10,480
Speaker 1: But one thing I found was that a lot of

876
00:52:10,560 --> 00:52:15,400
Speaker 1: spiders can go up to a year between feeding. Yeah,

877
00:52:15,480 --> 00:52:21,800
Speaker 1: between feeding, Yes, and that's surprising. Yeah, spiders fascinating. Yeah.

878
00:52:21,840 --> 00:52:23,920
Speaker 1: And Um, as I said in the Snakes one, I

879
00:52:24,560 --> 00:52:28,239
Speaker 1: don't kill spiders. But nothing would terrify me more than

880
00:52:28,280 --> 00:52:31,680
Speaker 1: a tarantula crawling up my arm. And that's funny too,

881
00:52:31,719 --> 00:52:36,200
Speaker 1: because tarantulas are not poisonous to humans. You can have

882
00:52:36,320 --> 00:52:39,840
Speaker 1: an allergic reaction to a tarantula, but in most people

883
00:52:39,880 --> 00:52:43,279
Speaker 1: who are allergic to tarantulas, you're allergic to their hair.

884
00:52:44,200 --> 00:52:46,400
Speaker 1: So crawling on you would would create maybe like a

885
00:52:46,400 --> 00:52:49,560
Speaker 1: skin rash or something. The venom is probably not going

886
00:52:49,640 --> 00:52:53,000
Speaker 1: to do much more than you might not even have

887
00:52:53,040 --> 00:52:56,880
Speaker 1: a reaction to it. You could feel pain from their

888
00:52:56,960 --> 00:53:00,879
Speaker 1: their fangs puncturing your skin, just like if I took

889
00:53:00,920 --> 00:53:03,000
Speaker 1: like a sewing needle and puncture just gonna be that

890
00:53:03,040 --> 00:53:05,880
Speaker 1: same kind of sensation. Um, I think it'd more just

891
00:53:05,960 --> 00:53:09,400
Speaker 1: be being freaked out that a tarantula is attacking you

892
00:53:09,440 --> 00:53:12,719
Speaker 1: would be the biggest setback from being attacked by a tarantula. Yeah,

893
00:53:12,760 --> 00:53:14,600
Speaker 1: I wouldn't even need to be attacked just you know,

894
00:53:14,640 --> 00:53:16,360
Speaker 1: you see movies where actors have to do that or

895
00:53:16,440 --> 00:53:18,799
Speaker 1: let one call over their face or something. There's no way,

896
00:53:19,280 --> 00:53:22,560
Speaker 1: no way, I could never ever ever do it. There's

897
00:53:22,840 --> 00:53:25,080
Speaker 1: I have a great Umi story when she was a kid.

898
00:53:25,360 --> 00:53:28,000
Speaker 1: She was at um one of the Smithsonians or whatever,

899
00:53:28,480 --> 00:53:31,480
Speaker 1: and they brought in like a thing full of tarantulas

900
00:53:31,880 --> 00:53:34,359
Speaker 1: and set them down. I think they actually dumped them

901
00:53:34,360 --> 00:53:37,080
Speaker 1: in the center of the kids or whatever. You just

902
00:53:37,200 --> 00:53:40,359
Speaker 1: got up and started really ran out of the room,

903
00:53:41,040 --> 00:53:43,399
Speaker 1: and her teacher had to run after her to catch

904
00:53:43,400 --> 00:53:46,400
Speaker 1: her again. She's like, you guys are idiots for sitting

905
00:53:46,480 --> 00:53:49,759
Speaker 1: here and thinking. I mean, I'm definitely in a rachnophobe

906
00:53:50,000 --> 00:53:52,360
Speaker 1: um oh, are you like died in the woold really

907
00:53:52,440 --> 00:53:56,760
Speaker 1: genuine to a certain degree, Like when I see a spider,

908
00:53:56,800 --> 00:53:59,600
Speaker 1: I'm not I'm I don't run away screaming, but if

909
00:53:59,760 --> 00:54:03,239
Speaker 1: it's proximity, if like one was on me, I would

910
00:54:03,239 --> 00:54:08,200
Speaker 1: not enjoy that experience of any size. And uh yeah,

911
00:54:08,320 --> 00:54:11,239
Speaker 1: so I'm I'm a bit of an anaphobe. What about

912
00:54:11,280 --> 00:54:14,520
Speaker 1: you? You You don't care? I mean, yeah, it's more like

913
00:54:14,560 --> 00:54:18,279
Speaker 1: when I can see they're the features and everything that

914
00:54:18,360 --> 00:54:22,400
Speaker 1: I'm really like because they're freaky creatures. Yeah, but I

915
00:54:22,440 --> 00:54:25,719
Speaker 1: loved my garden or weaver. I wasn't like that's you know,

916
00:54:26,040 --> 00:54:28,040
Speaker 1: it's someone are just beautiful, like the ones that are

917
00:54:28,040 --> 00:54:31,279
Speaker 1: like bright yellow and black, and like there's a lot

918
00:54:31,320 --> 00:54:34,680
Speaker 1: of really fascinating spiders. But no, I don't. I don't

919
00:54:34,719 --> 00:54:36,919
Speaker 1: want to be the focus of one's attention. I guess

920
00:54:37,000 --> 00:54:38,600
Speaker 1: is what it comes down to. Yeah, like when I'm

921
00:54:38,680 --> 00:54:41,240
Speaker 1: hiking through the woods and you walk your face walks

922
00:54:41,239 --> 00:54:45,759
Speaker 1: through a spider web, that is like, yeah, I did

923
00:54:45,880 --> 00:54:48,400
Speaker 1: not react. Well, yeah, like a little little girl. What

924
00:54:48,480 --> 00:54:51,759
Speaker 1: about the movie Rechnaphobia like that one? Yeah it was

925
00:54:51,800 --> 00:54:54,040
Speaker 1: good first time. I think I think so too. Yeah,

926
00:54:54,560 --> 00:54:58,560
Speaker 1: I'll sign off on that one. Was it Bill Pullman? Uh?

927
00:54:58,960 --> 00:55:01,520
Speaker 1: Was he in that or just annuals? Which one? Jeff,

928
00:55:01,840 --> 00:55:06,520
Speaker 1: Jeff Daniels and John Goodman. No, he was seeing that.

00:55:06,600 --> 00:55:09,560
Speaker 1: Yeah he was the external. Oh yeah, yeah, that's right. Yeah,

930
00:55:09,600 --> 00:55:13,200
Speaker 1: good flick. So that spiders everybody, Uh, if you want

931
00:55:13,239 --> 00:55:15,399
Speaker 1: to know more about them, Oh, chuck, we didn't talk

932
00:55:15,400 --> 00:55:18,200
Speaker 1: about the diving spider, one of the most fascinating spiders

933
00:55:18,200 --> 00:55:21,000
Speaker 1: of all. Yeah, we gotta, we gotta put that in. Yeah,

934
00:55:21,000 --> 00:55:24,600
Speaker 1: it's segues with our diving bell episode because they basically,

935
00:55:25,719 --> 00:55:29,760
Speaker 1: we've a little ceiling of spider web at the surface

936
00:55:29,760 --> 00:55:32,239
Speaker 1: of the water. No, underneath the water. Oh is it

937
00:55:32,320 --> 00:55:34,719
Speaker 1: underneath a little bit? Totally? Okay, So they'll we've a

938
00:55:34,719 --> 00:55:38,000
Speaker 1: little like ceiling, like a little parachute, and then they'll

939
00:55:38,000 --> 00:55:40,240
Speaker 1: take air bubbles under the air, one by one until

940
00:55:40,320 --> 00:55:43,440
Speaker 1: it's a little diving bell, right, And these spiders breathe

941
00:55:43,480 --> 00:55:46,640
Speaker 1: like any other spider above land, but they live underwater

942
00:55:47,280 --> 00:55:50,000
Speaker 1: almost all of their life, in this little pocket of

943
00:55:50,040 --> 00:55:51,960
Speaker 1: air that it builds for itself. And those are the

944
00:55:51,960 --> 00:55:55,279
Speaker 1: ones that will eat fish man. That's crazy awesome. Yeah,

945
00:55:55,680 --> 00:55:58,520
Speaker 1: there's all kinds of great documentaries online about spiders. They all,

946
00:55:58,880 --> 00:56:02,640
Speaker 1: unfortunately are sort of salacious, you know, with the music

947
00:56:02,719 --> 00:56:07,000
Speaker 1: and all this stuff. Um, it's fascinating, I think. Uh,

956
00:56:30,800 --> 00:56:34,360
Speaker 1: blood Types episode, I was surprised to know that animals

957
00:56:34,400 --> 00:56:37,000
Speaker 1: could donate blood as well, even though it makes perfect sense.

958
00:56:37,760 --> 00:56:40,719
Speaker 1: This is from Kara um or Carra. Hey, guys, I've

959
00:56:40,719 --> 00:56:42,359
Speaker 1: been listening for about four years and you guys keep

960
00:56:42,360 --> 00:56:44,360
Speaker 1: me company on my long commute and when I have

961
00:56:44,440 --> 00:56:47,840
Speaker 1: to drive the tractor. Uh. One year ago, we got

962
00:56:47,920 --> 00:56:49,920
Speaker 1: a call from some acquaintances of ours asking how much

963
00:56:49,920 --> 00:56:52,279
Speaker 1: our dog weighed. We didn't know them super well, but

964
00:56:52,320 --> 00:56:55,600
Speaker 1: being open minded, we said fifty six pounds and asked, uh.

965
00:56:55,840 --> 00:56:57,600
Speaker 1: They asked if we would be willing to let our

966
00:56:57,640 --> 00:57:00,120
Speaker 1: dog be a blood donor for their dog because as

967
00:57:00,120 --> 00:57:02,960
Speaker 1: their area was out of dog blood. Their dog had

968
00:57:03,000 --> 00:57:06,759
Speaker 1: been battling in a cute autoimmune issue for several days

969
00:57:06,760 --> 00:57:08,600
Speaker 1: and needed a dog over fifty pounds to be a

970
00:57:08,640 --> 00:57:12,240
Speaker 1: donor to get just through the night. Being animal lovers

971
00:57:12,239 --> 00:57:14,719
Speaker 1: and knowing my dog was healthy and fit, I didn't hesitate.

972
00:57:14,840 --> 00:57:17,640
Speaker 1: So we brought Hatchet in and they did a quick

973
00:57:17,640 --> 00:57:20,280
Speaker 1: test to see if the bloods were compatible, which was

974
00:57:20,320 --> 00:57:23,000
Speaker 1: basically swirling them together. They were a match, and we

975
00:57:23,080 --> 00:57:26,880
Speaker 1: proceeded with the transfusion. We didn't get to watch the process,

976
00:57:26,960 --> 00:57:30,200
Speaker 1: but Hatch came out about an hour later, a little drowsy,

977
00:57:30,280 --> 00:57:35,040
Speaker 1: but still his regular self to me exactly. He was

978
00:57:35,040 --> 00:57:36,640
Speaker 1: a little lazy the next day or two, but made

979
00:57:36,640 --> 00:57:38,520
Speaker 1: a fine recovery, and the other dog ended up making

980
00:57:38,520 --> 00:57:44,400
Speaker 1: a full recovery despite a bleak diagnosis. UM, if you

981
00:57:44,440 --> 00:57:46,560
Speaker 1: have a dog, I suggest finding friends with dogs fifty

982
00:57:46,560 --> 00:57:49,120
Speaker 1: pounds or more would be willing to be blood donors

983
00:57:49,160 --> 00:57:52,320
Speaker 1: in case of an emergency. Dog blood is often scarce.

984
00:57:53,120 --> 00:57:55,120
Speaker 1: So thanks guys, you've made me a champ at the

985
00:57:55,120 --> 00:57:59,760

987
00:58:02,040 --> 00:58:04,760
