1 00:00:02,200 --> 00:00:08,159 Speaker 1: Hello, everyone, It's October sixt What No, but this is 2 00:00:08,240 --> 00:00:11,239 Speaker 1: Chuck from the future past telling you to listen to 3 00:00:11,280 --> 00:00:15,320 Speaker 1: the selects pick for the week Jellyfish colon even cooler 4 00:00:15,360 --> 00:00:22,159 Speaker 1: than the OCTOPI you decide. Welcome to Stuff You should Know, 5 00:00:22,360 --> 00:00:30,840 Speaker 1: a production of I Heart Radios How Stuff Works. Hey, 6 00:00:30,880 --> 00:00:34,279 Speaker 1: and welcome to the podcast. I'm Josh Clark with Charles W. 7 00:00:34,440 --> 00:00:39,600 Speaker 1: Chuck Bryant with Jerry st You should know. Oh man, 8 00:00:39,720 --> 00:00:46,440 Speaker 1: let's start over all right, Well, that's okay. How you doing. 9 00:00:46,760 --> 00:00:51,080 Speaker 1: I'm good. I'm jet black still, I'm coming out of 10 00:00:51,120 --> 00:00:53,800 Speaker 1: it for sure, but yeah, I'm a little jetlike. I 11 00:00:53,960 --> 00:00:56,960 Speaker 1: just was explaining off Mike that my body is at 12 00:00:57,840 --> 00:01:00,960 Speaker 1: four thirty or five every morning. Does get up, dummy? 13 00:01:01,120 --> 00:01:05,920 Speaker 1: It's ten fifteen eleven, And I go, no, it's not. 14 00:01:06,000 --> 00:01:11,559 Speaker 1: It's dark. No internal struggle. And it's a British voice too. 15 00:01:12,319 --> 00:01:15,120 Speaker 1: It's like, get up, you need your beans and blood, 16 00:01:15,160 --> 00:01:20,360 Speaker 1: sausage and import pies. How was that? Oh man, I 17 00:01:20,440 --> 00:01:25,480 Speaker 1: want another one so bad, you know? Save that? Okay? Uh? 18 00:01:25,600 --> 00:01:28,720 Speaker 1: My jet leg is not so much pronounced in the morning, 19 00:01:29,160 --> 00:01:31,880 Speaker 1: it's just at nine thirty at night. I fall over 20 00:01:31,959 --> 00:01:34,760 Speaker 1: wherever I'm standing or said, you're just like cooking in 21 00:01:34,760 --> 00:01:37,440 Speaker 1: a walk and you just fall face for it. First 22 00:01:37,840 --> 00:01:40,760 Speaker 1: you noticed the burned face. Yeah, that's dangerous. Well it 23 00:01:40,880 --> 00:01:44,199 Speaker 1: hurt pretty bad because that walk grease gets pretty hot, 24 00:01:44,360 --> 00:01:51,680 Speaker 1: it does walk. What is this? What walks? Who walks? Still? Dude? 25 00:01:51,680 --> 00:01:55,560 Speaker 1: You kidney? No dark continents of people watch? Oh well sure, 26 00:01:56,440 --> 00:01:59,200 Speaker 1: but I just I guess I just imagined like wearing 27 00:01:59,240 --> 00:02:02,240 Speaker 1: a tennis or tied around my back. And I didn't 28 00:02:02,240 --> 00:02:09,400 Speaker 1: say fond should you're having a fond part of boiling cheese. 29 00:02:09,520 --> 00:02:13,960 Speaker 1: That's pretty seventies. You know what, if you ever want 30 00:02:13,960 --> 00:02:16,720 Speaker 1: a fond dupot and like because you think it'd be 31 00:02:16,720 --> 00:02:19,359 Speaker 1: fun to have a fond party, don't buy one new. 32 00:02:19,600 --> 00:02:23,320 Speaker 1: Just go to a goodwill. I went for like three dollars. Yeah, 33 00:02:23,480 --> 00:02:26,760 Speaker 1: you mean I have an unused one? Is it pea green? 34 00:02:29,200 --> 00:02:30,960 Speaker 1: I don't know if I would cook out of a 35 00:02:31,040 --> 00:02:35,760 Speaker 1: pea green anything? No? Yeah, all right, no, I wouldn't 36 00:02:36,080 --> 00:02:40,000 Speaker 1: pe green refrigerator. I wouldn't need out of it p 37 00:02:40,160 --> 00:02:42,240 Speaker 1: green car. I just throw up any time I want 38 00:02:42,280 --> 00:02:47,799 Speaker 1: to go drop uh, I'll tell you what I am 39 00:02:47,800 --> 00:02:52,080 Speaker 1: excited about though. Yeah, this is now officially my second 40 00:02:52,120 --> 00:02:59,640 Speaker 1: favorite seafaring creature after octopus, Yeah for sure. Yeah, and 41 00:02:59,680 --> 00:03:02,720 Speaker 1: this was close to like the jellyfish was really tugging 42 00:03:02,720 --> 00:03:06,400 Speaker 1: at my heartstrings. Yeah, and the and the octopus just 43 00:03:06,520 --> 00:03:10,440 Speaker 1: kept saying, you know what, remember me, remember the gramatophores. 44 00:03:10,480 --> 00:03:13,920 Speaker 1: Watch this bam. It looks at like something completely different. 45 00:03:14,360 --> 00:03:16,040 Speaker 1: And then I remember it. I was like, all right, octopus, 46 00:03:16,120 --> 00:03:20,360 Speaker 1: you're right, jellyfish can't do that. I'm Rocky the squirrel. Now, 47 00:03:20,360 --> 00:03:24,280 Speaker 1: I'm a romance soldier, I'm a cornucopia of vegetables in 48 00:03:24,280 --> 00:03:29,000 Speaker 1: an oil painting. Uh. They are pretty cool. Yeah, but 49 00:03:29,080 --> 00:03:33,120 Speaker 1: the jellyfish is really amazing. Yeah. The octopus is though 50 00:03:33,200 --> 00:03:36,680 Speaker 1: they're like they're doing it on purpose. The jellyfish just 51 00:03:36,800 --> 00:03:41,080 Speaker 1: accidentally kind of stumbles backwards into awesomeness. You know, well 52 00:03:41,120 --> 00:03:45,800 Speaker 1: after five million years of practice, maybe seven, Yeah, we'll see. 53 00:03:46,160 --> 00:03:49,560 Speaker 1: It's amazing. So when you're talking about jellyfish, a lot 54 00:03:49,560 --> 00:03:52,000 Speaker 1: of people say, well, there's a jellyfish, that's a jellyfish, 55 00:03:52,040 --> 00:03:54,240 Speaker 1: that's a jellyfish. That lady walking down the street with 56 00:03:54,280 --> 00:03:56,520 Speaker 1: the leash got a jellyfish on the end of right, 57 00:03:56,600 --> 00:04:01,920 Speaker 1: and and you would say jellyfish, jellyfish, comb, jelly dog, 58 00:04:03,320 --> 00:04:07,200 Speaker 1: or weird cat lady who walks her cat. Yeah, that's unwholesome. 59 00:04:07,640 --> 00:04:10,240 Speaker 1: That's as unwholesome as walking a jellyfish down this street 60 00:04:10,720 --> 00:04:15,680 Speaker 1: on a leash. So there are such things as comb jellies, 61 00:04:16,279 --> 00:04:19,880 Speaker 1: and there's jellyfish, and you out there who's lived maybe 62 00:04:19,880 --> 00:04:22,919 Speaker 1: ten twenty years on this planet or more, we've probably 63 00:04:22,920 --> 00:04:25,719 Speaker 1: seen them both. But it turns out that they look 64 00:04:25,839 --> 00:04:28,400 Speaker 1: very similar. But as we're finding out, as we get 65 00:04:28,440 --> 00:04:32,040 Speaker 1: deeper and deeper into using genetics to do taxonomy rather 66 00:04:32,080 --> 00:04:36,159 Speaker 1: than our peepers, that doesn't necessarily mean they're related. And 67 00:04:36,200 --> 00:04:40,120 Speaker 1: actually there's there's some tremendous debate between just how closely 68 00:04:40,160 --> 00:04:44,159 Speaker 1: related jellyfish and comb jellies are. Tremendous debate. Yes, we're 69 00:04:44,240 --> 00:04:47,520 Speaker 1: very subdued. It depends on where you are among like 70 00:04:47,680 --> 00:04:50,800 Speaker 1: fifty people. If you're in the jellyfish department of some 71 00:04:51,120 --> 00:04:55,080 Speaker 1: like the Monterey Bay Aquarium, I'll bet it gets nuts 72 00:04:55,120 --> 00:04:58,960 Speaker 1: a little vigorous. Yeah, they down some some old English 73 00:04:59,120 --> 00:05:03,440 Speaker 1: forty uh right, malt liquor and argue and to get 74 00:05:03,440 --> 00:05:06,719 Speaker 1: out the brass knuckles about taxonomy. Uh so that the 75 00:05:06,800 --> 00:05:10,760 Speaker 1: two phila they are different. Uh, we're talking respectively for 76 00:05:10,839 --> 00:05:17,120 Speaker 1: jellyfish and comb jellies. Uh, nadaria and ton afera. Yeah, nice, 77 00:05:17,200 --> 00:05:19,839 Speaker 1: and there's seas before. Both of them are both silent, 78 00:05:20,520 --> 00:05:30,840 Speaker 1: so it looks like centa bites and sephora. Yeah. Cento bytes. Yeah, 79 00:05:31,200 --> 00:05:33,680 Speaker 1: what is that a centerbon? That's no center bites. They 80 00:05:33,680 --> 00:05:37,000 Speaker 1: were the monsters in hell Raiser. Oh I thought it 81 00:05:37,000 --> 00:05:39,400 Speaker 1: was like a centabon that was in handy bite sized pieces. 82 00:05:39,440 --> 00:05:43,120 Speaker 1: That's a cinabyte. These are cento bites. Gotcha? Where where 83 00:05:43,120 --> 00:05:44,719 Speaker 1: did this research come from? By the way, a big 84 00:05:44,760 --> 00:05:48,279 Speaker 1: shout out Smithsonian. They have a site called the Ocean 85 00:05:48,320 --> 00:05:51,640 Speaker 1: Portal amazing that has all sorts of great stuff on it. Yeah, 86 00:05:51,640 --> 00:05:54,599 Speaker 1: you can't go wrong with Smithsonian. That's their their logo. 87 00:05:56,080 --> 00:05:59,800 Speaker 1: There's there's this that forms the basis of this one. 88 00:05:59,839 --> 00:06:01,760 Speaker 1: But I also want to give a huge shout out 89 00:06:01,839 --> 00:06:04,159 Speaker 1: to another article I read a while back that I 90 00:06:04,200 --> 00:06:06,599 Speaker 1: went back and reread. Actually it's called They're taking Over 91 00:06:07,040 --> 00:06:10,720 Speaker 1: and it was a New York View Books article on it. Yeah. Uh, 92 00:06:10,760 --> 00:06:15,560 Speaker 1: well reviewed a book on jellyfish, Yes, specifically jellyfish blooms 93 00:06:15,839 --> 00:06:19,480 Speaker 1: or when you'll see on the news like, oh my gosh, 94 00:06:19,520 --> 00:06:23,320 Speaker 1: there's five thousand jellyfish right here, right now, or thirty 95 00:06:23,400 --> 00:06:27,760 Speaker 1: three thousand square miles of jellyfish. But we'll get to that. Yeah, yeah, yeah, 96 00:06:27,760 --> 00:06:30,320 Speaker 1: were getting ahead of ourselves. So there's jellyfish and comb 97 00:06:30,400 --> 00:06:32,560 Speaker 1: jellies and there we don't know if they're related. They 98 00:06:32,560 --> 00:06:36,240 Speaker 1: look a lot like they're very much. Um, they seem related, 99 00:06:36,320 --> 00:06:39,800 Speaker 1: So we're gonna talk about both. Yes, right, so let's 100 00:06:39,800 --> 00:06:42,040 Speaker 1: talk about him, Chuck. All right, Well we'll start off 101 00:06:42,080 --> 00:06:46,799 Speaker 1: with the body, uh, because well they're kind of all body. Uh. 102 00:06:46,839 --> 00:06:49,880 Speaker 1: They both jellyfish income jellies have they have a lot 103 00:06:49,920 --> 00:06:52,920 Speaker 1: of differences, but you know, when you look under the hood, 104 00:06:52,960 --> 00:06:55,159 Speaker 1: they have a lot of similarities, which is why you 105 00:06:55,160 --> 00:06:58,680 Speaker 1: would expect when people use their peepers they would just think, well, yeah, 106 00:06:58,720 --> 00:07:00,240 Speaker 1: of course you have the same look at them. Yeah, 107 00:07:01,320 --> 00:07:05,240 Speaker 1: don't don't think too don't overthink it. That was early science. 108 00:07:05,480 --> 00:07:08,320 Speaker 1: Don't overthink it. So both of them have a couple 109 00:07:08,360 --> 00:07:11,640 Speaker 1: of major cell layers, the external epidermis and then the 110 00:07:11,760 --> 00:07:17,000 Speaker 1: internal one called the gastrodermist. And in between those is 111 00:07:17,480 --> 00:07:23,240 Speaker 1: what you think of as jellyfish. Yeah, that's the mesoglia, yeah, 112 00:07:23,240 --> 00:07:27,440 Speaker 1: which is a great name for that, and it's the filling. Yeah, 113 00:07:27,600 --> 00:07:30,560 Speaker 1: it's it's nine. And in fact, jellyfish and come jellies 114 00:07:30,560 --> 00:07:35,840 Speaker 1: are about water. Yeah, seawater actually salt and water. They're 115 00:07:35,880 --> 00:07:39,160 Speaker 1: basically made up of the sea. I saw it put somewhere. Yeah, 116 00:07:39,200 --> 00:07:44,120 Speaker 1: you know, it's amazing. Um. So they have basically one 117 00:07:44,520 --> 00:07:50,320 Speaker 1: mouth where um stuff goes in and comes out. It's 118 00:07:50,360 --> 00:07:55,720 Speaker 1: like a U mouth and oral anis basically I don't 119 00:07:55,760 --> 00:07:57,440 Speaker 1: even know if they refer to it as a mouth. 120 00:07:57,480 --> 00:07:59,960 Speaker 1: Do they like somewhere in this thing? Didn't they called 121 00:08:00,000 --> 00:08:03,280 Speaker 1: it literally like a body hole or something. Yeah, it's 122 00:08:03,360 --> 00:08:06,880 Speaker 1: it's a pretty basic, basic organism, but it does a 123 00:08:06,880 --> 00:08:09,320 Speaker 1: lot of things. Yeah, so it's not Yeah, when you 124 00:08:09,320 --> 00:08:11,800 Speaker 1: think of mouth, you just think eating. Not necessarily, Hey, 125 00:08:11,880 --> 00:08:15,240 Speaker 1: let's put some sperm and egg in there too. It's 126 00:08:15,280 --> 00:08:18,480 Speaker 1: like all purpose. Yeah, but they don't necessarily need in 127 00:08:18,480 --> 00:08:22,280 Speaker 1: a mouth for eating because apparently they can absorb nutrients 128 00:08:22,360 --> 00:08:25,160 Speaker 1: like just through their skin. Yeah, so they have they 129 00:08:25,200 --> 00:08:27,680 Speaker 1: don't have a stomach, they don't have intestines, they don't 130 00:08:27,680 --> 00:08:30,160 Speaker 1: have lungs. They're just like, get in my get in 131 00:08:30,240 --> 00:08:34,160 Speaker 1: my skin nutrients yeah, and oxygen, And if you think 132 00:08:34,200 --> 00:08:37,360 Speaker 1: about it, then they don't need lungs. They don't need 133 00:08:37,880 --> 00:08:41,400 Speaker 1: like a they don't need a mouth, so they don't 134 00:08:41,440 --> 00:08:44,840 Speaker 1: need to chew. All this stuff requires a lot of energy. 135 00:08:45,440 --> 00:08:50,440 Speaker 1: They actually are extraordinarily efficient organisms, so they get a 136 00:08:50,559 --> 00:08:53,120 Speaker 1: lot more energy out of the stuff that they take 137 00:08:53,160 --> 00:08:56,520 Speaker 1: in than other things, which actually gives them a huge 138 00:08:56,559 --> 00:08:59,840 Speaker 1: advantages we'll see later. Uh. So the outer cells, they 139 00:08:59,840 --> 00:09:03,040 Speaker 1: have this epidermis, like we said, and it has what's 140 00:09:03,080 --> 00:09:07,000 Speaker 1: called a nerve net, and it's just this net of 141 00:09:07,080 --> 00:09:11,640 Speaker 1: nerves literally, um, and that it's it's it's their nervous 142 00:09:11,640 --> 00:09:15,920 Speaker 1: system basically, and it's the it's the most basic, Um, 143 00:09:15,960 --> 00:09:19,640 Speaker 1: I guess, brain like structure of any organism on the planet, 144 00:09:20,080 --> 00:09:23,719 Speaker 1: of any multicellular organism. I guess that's right. And so 145 00:09:23,760 --> 00:09:25,880 Speaker 1: in the nerve net, not only does it have nerves, 146 00:09:25,920 --> 00:09:28,920 Speaker 1: it also has some sort of specialized cells, like some 147 00:09:29,040 --> 00:09:31,960 Speaker 1: that detect light so they can know that they need 148 00:09:32,000 --> 00:09:37,199 Speaker 1: to move away from that boat spotlight. Uh, and then 149 00:09:37,280 --> 00:09:39,520 Speaker 1: some that tell them whether they're moving up or down 150 00:09:39,640 --> 00:09:43,599 Speaker 1: or whether they're upside down. Yeah, big dummies, that's a 151 00:09:43,720 --> 00:09:45,880 Speaker 1: that's a big one. You think about it. But I mean, 152 00:09:46,000 --> 00:09:49,520 Speaker 1: like that's if you don't have eyeballs. No, But this 153 00:09:49,559 --> 00:09:51,880 Speaker 1: is the weird part. Man, this is so disturbing to me. 154 00:09:51,960 --> 00:09:56,440 Speaker 1: This is almost as disturbing as squid having beaks. Some 155 00:09:57,400 --> 00:10:02,719 Speaker 1: types of jellies, box jellies, in particular um box jellyfish 156 00:10:03,000 --> 00:10:08,480 Speaker 1: have eyes. They have retinas lenses, but they don't have 157 00:10:08,480 --> 00:10:12,240 Speaker 1: a brain. So scientists are like, how what how are 158 00:10:12,280 --> 00:10:15,920 Speaker 1: you processing these images that you're clearly taking in and 159 00:10:15,960 --> 00:10:19,920 Speaker 1: responding to, Like, we've shown you pictures of like um 160 00:10:20,880 --> 00:10:24,520 Speaker 1: Sheryl lad and you like gave a thumbs up. So 161 00:10:24,679 --> 00:10:28,480 Speaker 1: obviously you can use these eyes, but how are you 162 00:10:28,600 --> 00:10:31,760 Speaker 1: sorting these images? You know? Yeah, they think it's that 163 00:10:31,960 --> 00:10:35,320 Speaker 1: that nerve ring, but they're not sure, right, and that's 164 00:10:35,320 --> 00:10:40,440 Speaker 1: a ring around Uh, it's concentration of nerves basically that 165 00:10:40,520 --> 00:10:43,040 Speaker 1: they haven't figured out yet. But they think that's there 166 00:10:43,040 --> 00:10:48,400 Speaker 1: in is the secret. It would be like, um, it 167 00:10:48,640 --> 00:10:52,880 Speaker 1: would be like now, I can't come with a good analogy. 168 00:10:53,240 --> 00:10:55,080 Speaker 1: There's a million of them out there, but I'm not 169 00:10:55,520 --> 00:10:58,679 Speaker 1: still jet Like I guess I just want to apologize 170 00:10:58,679 --> 00:11:00,880 Speaker 1: to everybody because that could have been I was on 171 00:11:00,920 --> 00:11:04,080 Speaker 1: the edge of my seat. Uh. Uh. So comb jellies 172 00:11:04,120 --> 00:11:07,120 Speaker 1: they have a few things that the regular jelly does 173 00:11:07,160 --> 00:11:11,200 Speaker 1: not have. Uh. Most notably the comb their name for 174 00:11:11,280 --> 00:11:16,280 Speaker 1: these uh silia, these giant fuse cilia. There's eight rows 175 00:11:17,040 --> 00:11:20,080 Speaker 1: up and down their bodies and they basically are their 176 00:11:20,280 --> 00:11:23,240 Speaker 1: ways of locomotive neck like little bitty oars paddling around 177 00:11:23,280 --> 00:11:26,760 Speaker 1: in the water. And there are other animals that do this, 178 00:11:26,840 --> 00:11:28,880 Speaker 1: but the comb jelly is the largest one to do 179 00:11:28,960 --> 00:11:32,200 Speaker 1: this and to use this kind of locomotion. And it 180 00:11:32,240 --> 00:11:34,600 Speaker 1: looks like a rainbow if you look one up, but 181 00:11:34,679 --> 00:11:37,240 Speaker 1: you think it might be bioluminescent, but it's not. It's 182 00:11:37,280 --> 00:11:41,520 Speaker 1: just light catching the cilia and scattering it. It's beautiful, 183 00:11:43,440 --> 00:11:45,720 Speaker 1: It is quite beautiful. But that's the thing that that 184 00:11:45,800 --> 00:11:50,680 Speaker 1: separates comb jellies from jelly jellyfish most um pronounced lee right, Yeah, 185 00:11:50,880 --> 00:11:55,960 Speaker 1: because a lot of their activities and just the stuff 186 00:11:56,000 --> 00:11:59,520 Speaker 1: that they do, it's fairly similar the TV they watch, 187 00:12:00,360 --> 00:12:03,280 Speaker 1: but their means of locomotion are are really the big, 188 00:12:03,640 --> 00:12:07,040 Speaker 1: huge distinction. Yeah. The A lot of the comb jellies 189 00:12:07,080 --> 00:12:09,520 Speaker 1: have a single pair just two tentacles, but it looks 190 00:12:09,559 --> 00:12:12,240 Speaker 1: like more because they branch out um and they use 191 00:12:12,280 --> 00:12:15,480 Speaker 1: those like little fishing lines because they have sticky cells 192 00:12:15,679 --> 00:12:18,760 Speaker 1: uh color blast at the end. And this is different 193 00:12:18,960 --> 00:12:22,520 Speaker 1: uh big time than jellyfish. They don't sting. No, they 194 00:12:22,640 --> 00:12:26,120 Speaker 1: use um gluey, which is pretty neat, so you won't 195 00:12:26,120 --> 00:12:29,120 Speaker 1: be stung by a comb jelly. So just swim up 196 00:12:29,120 --> 00:12:34,160 Speaker 1: and hug one. They love it when you do that. So. Um, 197 00:12:34,200 --> 00:12:36,440 Speaker 1: when you think of a jellyfish, like a true jelly 198 00:12:36,520 --> 00:12:40,120 Speaker 1: is what what they're called. Um there you think of 199 00:12:40,160 --> 00:12:44,840 Speaker 1: like kind of this bell shaped umbrella shaped thing with 200 00:12:44,880 --> 00:12:48,400 Speaker 1: the tentacles hanging down. Beautiful. And if it's a jellyfish, 201 00:12:48,679 --> 00:12:51,120 Speaker 1: that's actually one of two forms that it will take 202 00:12:51,160 --> 00:12:55,480 Speaker 1: in its lifetime. Right, Um, it's that's the medusa form, 203 00:12:55,800 --> 00:12:59,439 Speaker 1: and it's it's the adult form. There's a juvenile form 204 00:12:59,480 --> 00:13:03,200 Speaker 1: called the all up and um. Depending on when it 205 00:13:03,320 --> 00:13:05,560 Speaker 1: is in its life cycle, it will either be in 206 00:13:05,559 --> 00:13:08,400 Speaker 1: a medusa form a polyp form. Yeah, and we'll get 207 00:13:08,440 --> 00:13:10,200 Speaker 1: into the little more of the life cycle. But a 208 00:13:10,200 --> 00:13:14,400 Speaker 1: polyp can end up becoming a medusa or just might 209 00:13:14,480 --> 00:13:16,559 Speaker 1: be happy as little polyp and to stay as a 210 00:13:16,600 --> 00:13:19,640 Speaker 1: poly up and create more meducea. Yeah, and the polyp 211 00:13:19,679 --> 00:13:23,480 Speaker 1: looks like um, it almost looks like a plant. It 212 00:13:23,520 --> 00:13:27,000 Speaker 1: looks like a little stalk attached to something, usually the 213 00:13:27,040 --> 00:13:30,800 Speaker 1: sand or as we'll see, maybe a oil rig out 214 00:13:30,800 --> 00:13:32,360 Speaker 1: in the middle of the ocean or something, or share 215 00:13:32,360 --> 00:13:36,200 Speaker 1: a lad. That's right, because she's she's a deep water 216 00:13:36,280 --> 00:13:41,600 Speaker 1: dweller at this point. Um. So it looks like a 217 00:13:41,600 --> 00:13:43,440 Speaker 1: little plant. It's got it looks like a little stalk, 218 00:13:43,559 --> 00:13:47,320 Speaker 1: and then the uh, tentacles are blooming out of it, 219 00:13:47,360 --> 00:13:51,040 Speaker 1: almost like a flower. Yeah, like anemone or something like that. Yeah. 220 00:13:51,080 --> 00:13:53,680 Speaker 1: And sometimes you see him many many of them together 221 00:13:53,720 --> 00:13:56,480 Speaker 1: in a colony. You think that's an amazing plant. It's 222 00:13:56,520 --> 00:13:59,320 Speaker 1: actually a jelly. Yeah, pretty cool if you would be 223 00:13:59,360 --> 00:14:01,400 Speaker 1: able to tell if you poked it with your finger. 224 00:14:02,040 --> 00:14:06,040 Speaker 1: That's right. So the size among jellies ants and um 225 00:14:06,200 --> 00:14:10,640 Speaker 1: comb jellies are I mean, some of are just microscopic, 226 00:14:11,280 --> 00:14:14,160 Speaker 1: others get pretty big. If there's one called the lion's 227 00:14:14,200 --> 00:14:18,000 Speaker 1: main jellyfish, which on the whole across like the whole species, 228 00:14:18,400 --> 00:14:21,720 Speaker 1: they are the largest jellyfish known to humankind. Did you 229 00:14:21,760 --> 00:14:25,400 Speaker 1: see this thing? Yeah, it looks like photoshop when you 230 00:14:25,440 --> 00:14:29,120 Speaker 1: see a scuba diver up next to one. It definitely does. 231 00:14:29,520 --> 00:14:34,760 Speaker 1: Like the bell actually gets to be six ft wide. Yeah, 232 00:14:34,800 --> 00:14:39,040 Speaker 1: And the tentacles are like, um long, fifty ft long, 233 00:14:39,640 --> 00:14:42,600 Speaker 1: and some some get bigger than that. But that's you know, 234 00:14:42,680 --> 00:14:47,280 Speaker 1: the average size of one of those. This is pretty neat. Yeah, 235 00:14:47,320 --> 00:14:51,400 Speaker 1: I mean they're not to be feared. But swimming up 236 00:14:51,400 --> 00:14:54,400 Speaker 1: to something that large and that kind of creepy looking 237 00:14:54,720 --> 00:14:57,760 Speaker 1: is not for me, that's all. I'll say. That eats anything, 238 00:14:58,080 --> 00:15:02,000 Speaker 1: it'll eat anything like people. Yeah, No, I won't need 239 00:15:02,080 --> 00:15:07,360 Speaker 1: a person. Yeah, I don't know. If they were big enough, 240 00:15:07,400 --> 00:15:10,240 Speaker 1: it might. All right, So let's talk a little bit 241 00:15:10,240 --> 00:15:14,760 Speaker 1: about the various types. Um. We'll start with Nadaria, which 242 00:15:14,840 --> 00:15:19,440 Speaker 1: is the the jellyfish itself, not the comb. There are 243 00:15:19,480 --> 00:15:22,880 Speaker 1: more than ten thousand species, uh, and about four thousand 244 00:15:22,960 --> 00:15:25,680 Speaker 1: or fewer actually are what we think of as the 245 00:15:25,680 --> 00:15:29,320 Speaker 1: true jelly the medusa that we know and love, uh. 246 00:15:29,360 --> 00:15:32,840 Speaker 1: And within that there are quite a few different types, 247 00:15:33,240 --> 00:15:37,240 Speaker 1: one of which is the skiff a zoa. And this 248 00:15:37,320 --> 00:15:41,520 Speaker 1: is the most common true jellyfish that you can imagine. 249 00:15:41,880 --> 00:15:45,040 Speaker 1: When you picture jelly fish in your mind, you're probably 250 00:15:45,080 --> 00:15:49,800 Speaker 1: thinking of the skiff a zoa um. The hydrozoa are 251 00:15:50,200 --> 00:15:55,280 Speaker 1: um impostors. Well, they're they're the ones who they spend 252 00:15:55,360 --> 00:15:58,000 Speaker 1: most of their time as polyps, right, So the skiff 253 00:15:58,000 --> 00:16:00,920 Speaker 1: a zoa spend most of their time in the medusas phase. 254 00:16:01,600 --> 00:16:04,840 Speaker 1: The hydrozoa are the ones that look like plants at 255 00:16:04,840 --> 00:16:08,880 Speaker 1: the bottom and are just reproducing like mad um, and 256 00:16:08,960 --> 00:16:12,680 Speaker 1: they actually can come together and create what are called 257 00:16:12,720 --> 00:16:17,000 Speaker 1: colonial siphon of force. And that's a you know, a 258 00:16:17,040 --> 00:16:20,880 Speaker 1: Portuguese man of war. Okay, So that is actually not 259 00:16:21,040 --> 00:16:24,840 Speaker 1: a true jellyfish. It's actually a collection. It's a it's 260 00:16:24,840 --> 00:16:29,720 Speaker 1: a colony that comes together to act like one large organism, right, 261 00:16:30,240 --> 00:16:33,040 Speaker 1: and it's made up of persons, so like there's the 262 00:16:33,240 --> 00:16:37,080 Speaker 1: person that is in charge of digestion, there's the person 263 00:16:37,160 --> 00:16:40,240 Speaker 1: that's in charge of catching prey. There's the person that's 264 00:16:40,240 --> 00:16:43,720 Speaker 1: in charge of locomotion. And rather than these things being 265 00:16:43,760 --> 00:16:47,840 Speaker 1: body parts, they're actually individual organisms that are genetically identical 266 00:16:47,880 --> 00:16:50,240 Speaker 1: to one another because they all come from the same egg. 267 00:16:50,640 --> 00:16:54,920 Speaker 1: But they're actually a colony. Does that make sense? Like, 268 00:16:55,000 --> 00:17:00,160 Speaker 1: imagine if your organs were various actual organisms that came 269 00:17:00,200 --> 00:17:03,120 Speaker 1: together to make you. It's like the polyphonic spree of 270 00:17:04,040 --> 00:17:07,000 Speaker 1: the ocean world. Exactly. It's amazing. That's exactly what I 271 00:17:07,040 --> 00:17:10,080 Speaker 1: was driving at. Uh. Next up we have the Cuba 272 00:17:10,160 --> 00:17:13,320 Speaker 1: zoa and that's you mentioned the box jellyfish. They look 273 00:17:13,400 --> 00:17:16,159 Speaker 1: like a box is more squared looking. Those are the 274 00:17:16,200 --> 00:17:19,200 Speaker 1: most dangerous ones. Yeah. They have the most potent venom 275 00:17:19,280 --> 00:17:23,160 Speaker 1: and it is stuff not just of jellyfish, of any 276 00:17:23,280 --> 00:17:26,000 Speaker 1: animal on the planet. Yeah, the sea wasp has the 277 00:17:26,040 --> 00:17:32,679 Speaker 1: most powerful venom for humans, I should say the sea wasp. 278 00:17:33,160 --> 00:17:36,240 Speaker 1: And that just awesome sounding. Yeah, it sounds like something 279 00:17:36,280 --> 00:17:39,360 Speaker 1: you want to avoid at all costs. Yeah. Uh so 280 00:17:39,440 --> 00:17:41,880 Speaker 1: these guys are the ones that have a more complex 281 00:17:41,920 --> 00:17:46,080 Speaker 1: nervous system, that have the the eyes right, Yeah, with 282 00:17:46,119 --> 00:17:48,480 Speaker 1: the corneas and things. So they're the most deadly and 283 00:17:48,480 --> 00:17:52,640 Speaker 1: they're looking at you. Yeah, they're saying, I'm coming for you. 284 00:17:53,520 --> 00:17:58,520 Speaker 1: The star o zoa stalk jellyfishes, and they don't float. 285 00:17:59,240 --> 00:18:01,720 Speaker 1: They are actually like to cling onto things and attached 286 00:18:01,720 --> 00:18:05,000 Speaker 1: to things, and they are mainly cold water. But all 287 00:18:05,200 --> 00:18:08,320 Speaker 1: you can find most all kinds are not all kinds. 288 00:18:08,400 --> 00:18:10,920 Speaker 1: You can find some kind of jellyfish and almost any 289 00:18:11,160 --> 00:18:14,560 Speaker 1: kind of water, any kind of ocean water in the world. Well, 290 00:18:14,640 --> 00:18:17,480 Speaker 1: not just that there's some thrive and freshwater. There's a 291 00:18:17,560 --> 00:18:20,720 Speaker 1: type of jellyfish that is um all over the Great Lakes. 292 00:18:21,880 --> 00:18:25,040 Speaker 1: It was originally it's native to China, and they think 293 00:18:25,040 --> 00:18:28,560 Speaker 1: that it was brought over originally from China to England 294 00:18:29,080 --> 00:18:33,000 Speaker 1: in like a water lily shipment, because it was first 295 00:18:33,000 --> 00:18:36,800 Speaker 1: discovered in the West in like garden ponds, and it 296 00:18:36,920 --> 00:18:39,600 Speaker 1: somehow made its way to the Great Lakes. And now 297 00:18:39,640 --> 00:18:42,680 Speaker 1: there's a freshwater jellyfish that's about I think the size 298 00:18:42,680 --> 00:18:46,119 Speaker 1: of your thumbnail, depending on what size your thumbnail is 299 00:18:46,560 --> 00:18:49,240 Speaker 1: in the Great Lakes. That's a jellyfish. And it's a 300 00:18:49,240 --> 00:18:53,520 Speaker 1: true jellyfish. And we should say also with um jellyfish locomotion, 301 00:18:53,560 --> 00:18:56,200 Speaker 1: they don't use the silly a like a comb jellyfish 302 00:18:56,240 --> 00:19:01,760 Speaker 1: does They in Medusa form x banned and contract the 303 00:19:01,760 --> 00:19:04,200 Speaker 1: bell right, so beautiful. And I was reading I think 304 00:19:04,200 --> 00:19:07,720 Speaker 1: it was a Scientific American or Popular Science, one of 305 00:19:07,720 --> 00:19:10,400 Speaker 1: those two all posted on the podcast Pitch, but it 306 00:19:10,480 --> 00:19:15,360 Speaker 1: was they some researchers examined how jellyfish move and they 307 00:19:15,400 --> 00:19:18,879 Speaker 1: found that not only are they like um able to 308 00:19:19,000 --> 00:19:23,480 Speaker 1: move when they when they expand and then contract in 309 00:19:23,560 --> 00:19:27,600 Speaker 1: the resting motion of their bell, of vortex actually forms 310 00:19:27,640 --> 00:19:30,959 Speaker 1: in the water above them and moves beneath them and 311 00:19:31,000 --> 00:19:33,760 Speaker 1: moves them up that way. So they're constantly moving, but 312 00:19:33,800 --> 00:19:37,280 Speaker 1: they're only exerting like half of the energy needed to 313 00:19:37,320 --> 00:19:41,360 Speaker 1: move forward. To propel forward or upward. Right, So that's 314 00:19:41,400 --> 00:19:45,840 Speaker 1: even one more way that they're incredibly efficient type of animal. Yeah, 315 00:19:45,960 --> 00:19:49,720 Speaker 1: without a brain, they're pretty smart, you know what I mean. Uh, 316 00:19:49,800 --> 00:19:51,760 Speaker 1: should we take a break? Yeah, all right, we'll take 317 00:19:51,760 --> 00:19:53,760 Speaker 1: a break, and we're gonna come back and dive into 318 00:19:53,840 --> 00:20:20,960 Speaker 1: the wonderful world of comb jellies. All right. So we 319 00:20:21,040 --> 00:20:25,399 Speaker 1: talked about just a few of the standard jellyfish. The 320 00:20:25,440 --> 00:20:30,640 Speaker 1: comb jellies are way way fewer species of the tina fours. Um, 321 00:20:30,680 --> 00:20:33,439 Speaker 1: we're talking I think ten thousand for the other this 322 00:20:33,520 --> 00:20:39,920 Speaker 1: is about a hundred fifty. Yeah, not even hundred fifty. Yeah, 323 00:20:39,960 --> 00:20:43,280 Speaker 1: But they're saying that it's possible that these are just 324 00:20:43,400 --> 00:20:47,200 Speaker 1: the ones we are aware of because um, we've encountered 325 00:20:47,200 --> 00:20:49,760 Speaker 1: them in coastal waters, that they may be way more 326 00:20:49,760 --> 00:20:52,720 Speaker 1: in deep sea. Yeah, they don't know much about those guys, right, right. 327 00:20:52,880 --> 00:20:54,520 Speaker 1: And the ones that are in deep see that we've 328 00:20:54,600 --> 00:20:58,520 Speaker 1: encountered tend to be so fragile that we can't collect them. Yeah, 329 00:20:58,560 --> 00:21:00,479 Speaker 1: because they're not tough, because they don't to put up 330 00:21:00,520 --> 00:21:03,200 Speaker 1: with the you know, their merrids and waves and yeah, 331 00:21:03,359 --> 00:21:05,399 Speaker 1: they just float out there and yeah, you look at 332 00:21:05,440 --> 00:21:09,000 Speaker 1: them too hard. And they crumble. Um. So one type 333 00:21:09,000 --> 00:21:13,480 Speaker 1: of a comb jelly is uh sodipid uh and they 334 00:21:13,480 --> 00:21:16,760 Speaker 1: are all around their spherical or oval. They have those 335 00:21:16,760 --> 00:21:20,000 Speaker 1: branch tentacles that we talked about. Those tentacles are a 336 00:21:20,000 --> 00:21:21,960 Speaker 1: little unique and that they can actually draw them back 337 00:21:22,000 --> 00:21:24,720 Speaker 1: into the body when it's cold, yeah, which is pretty cool. 338 00:21:25,080 --> 00:21:28,919 Speaker 1: Really okay, so I believe uh yeah. And they have 339 00:21:29,000 --> 00:21:31,440 Speaker 1: like sheets on the sides of their mouths that it 340 00:21:31,520 --> 00:21:35,080 Speaker 1: draws back into which is pretty cool amazing. Um. Then 341 00:21:35,119 --> 00:21:39,920 Speaker 1: there's low baits uh, which have lobes on the sides, 342 00:21:40,080 --> 00:21:45,000 Speaker 1: right yeah, um, and that's about it. They have the 343 00:21:45,040 --> 00:21:49,080 Speaker 1: lobes and that's what they're known for baroids. These are 344 00:21:49,119 --> 00:21:52,560 Speaker 1: kind of cool. These are the dudes that have no tentacles. 345 00:21:53,440 --> 00:21:55,679 Speaker 1: So the way they eat is they have a big, 346 00:21:55,720 --> 00:21:58,760 Speaker 1: big mouth that draws in a lot of stuff and 347 00:21:58,760 --> 00:22:02,560 Speaker 1: then a very tight, almost zipper like thing that shuts 348 00:22:03,080 --> 00:22:05,159 Speaker 1: and then they can shut that mouth really hard and 349 00:22:05,280 --> 00:22:08,200 Speaker 1: just mush all that stuff up. Well. They they have 350 00:22:08,280 --> 00:22:11,920 Speaker 1: silia inside their mouths that act like teeds that pull 351 00:22:12,000 --> 00:22:17,600 Speaker 1: their prey apart alive teeth tooth teeth. Yeah, oh man, 352 00:22:17,680 --> 00:22:22,119 Speaker 1: it's weird. Jet leg um. But the little the teeth 353 00:22:22,200 --> 00:22:25,080 Speaker 1: just pick it like their prey and just pull them apart. 354 00:22:25,160 --> 00:22:28,640 Speaker 1: It dissolves them, basically mechanically amazing. Have you ever seen 355 00:22:28,680 --> 00:22:33,520 Speaker 1: a video of um, the uh, the pelican who's just 356 00:22:33,560 --> 00:22:35,760 Speaker 1: standing there and there's a pigeon like on the ground 357 00:22:35,840 --> 00:22:37,320 Speaker 1: right in front of him, and all of a sudden 358 00:22:37,320 --> 00:22:39,959 Speaker 1: the pigeon the pelican just eats the pigeon, and the 359 00:22:40,000 --> 00:22:42,200 Speaker 1: pigeons like trying to get out of the pelicans like 360 00:22:42,320 --> 00:22:46,360 Speaker 1: huge mouth, and the pelicans just sitting there like nothing's happening. 361 00:22:46,640 --> 00:22:49,520 Speaker 1: And then finally like the pigeon stops moving. It is 362 00:22:50,000 --> 00:22:54,359 Speaker 1: really disturbing because you you you know, like pelicans don't 363 00:22:54,359 --> 00:22:57,240 Speaker 1: normally eat live pigeons, so there's like there's something wrong 364 00:22:57,280 --> 00:23:01,120 Speaker 1: with this pelican or it was just then steely reserve, 365 00:23:01,480 --> 00:23:06,159 Speaker 1: like no remorse whatsoever. Yeah, it's a it's a disconcerting video, 366 00:23:06,440 --> 00:23:09,840 Speaker 1: especially if you're a pigeon lover, which I'm not. I'm 367 00:23:09,880 --> 00:23:12,480 Speaker 1: it sound like I hate pigeons, but you don't want 368 00:23:12,480 --> 00:23:16,200 Speaker 1: to see him get you know, eaten eaten by a pelican. Yeah, 369 00:23:16,240 --> 00:23:19,560 Speaker 1: it's it's weird. It's totally strange. Where do you find 370 00:23:19,600 --> 00:23:23,639 Speaker 1: this stuff? It's around so weird. I think you may 371 00:23:23,720 --> 00:23:26,159 Speaker 1: showed me that one. Yeah. You guys always have a 372 00:23:26,160 --> 00:23:29,639 Speaker 1: lot of weird videos at your fingertips. You and you 373 00:23:29,760 --> 00:23:31,600 Speaker 1: we were just always talking about, like did you see 374 00:23:31,600 --> 00:23:35,159 Speaker 1: the one where you know, the pelican ate the pigeon. Yeah, 375 00:23:35,359 --> 00:23:40,520 Speaker 1: I guess so that's pretty neat. Um Comb jellies distribution wise, 376 00:23:40,520 --> 00:23:43,399 Speaker 1: they are also all over the oceans. Uh. They do 377 00:23:43,480 --> 00:23:45,880 Speaker 1: perform a little warmer water though, but you can't find 378 00:23:45,880 --> 00:23:49,240 Speaker 1: them anywhere, right. Um. So we're talking earlier about the 379 00:23:49,240 --> 00:23:52,320 Speaker 1: fact that they are from different phyla and that there's this, 380 00:23:52,560 --> 00:23:57,080 Speaker 1: you know, drunken argument going on among scientists at the 381 00:23:57,119 --> 00:24:02,000 Speaker 1: Monterey Bay aquari about how how closely related they are. Um. 382 00:24:02,080 --> 00:24:06,560 Speaker 1: They used to all be described as uh sellin slinarata, 383 00:24:06,840 --> 00:24:11,080 Speaker 1: which is hollow bellied. Oh yeah, makes sense, But they don't. 384 00:24:11,080 --> 00:24:14,480 Speaker 1: They don't say that anymore. And if you want to 385 00:24:14,480 --> 00:24:18,640 Speaker 1: be ridiculed by your peers, call them that. But some 386 00:24:18,680 --> 00:24:21,680 Speaker 1: people say, you know, their sister groups. Some people say, nope, 387 00:24:21,720 --> 00:24:25,240 Speaker 1: they're not even that closely related. Uh So the debate 388 00:24:25,320 --> 00:24:29,280 Speaker 1: rages on. I guess yep. So, Um, what what's interesting 389 00:24:29,320 --> 00:24:31,600 Speaker 1: is that we even know how long jellies have been 390 00:24:31,600 --> 00:24:36,560 Speaker 1: around because there they have no solid parts. Yeah, you'd 391 00:24:36,560 --> 00:24:39,199 Speaker 1: think it'd be hard to find a fossil. They have 392 00:24:39,240 --> 00:24:42,439 Speaker 1: gelatinous parts, they don't have any hardened parts. Yeah, that 393 00:24:42,440 --> 00:24:45,399 Speaker 1: would be fossilized easily. But there have been some discoveries, 394 00:24:45,400 --> 00:24:50,240 Speaker 1: some amazing discoveries of jellyfish and um comb jellies from 395 00:24:50,280 --> 00:24:53,679 Speaker 1: about five million years ago. It's the I believe, the 396 00:24:53,720 --> 00:24:57,320 Speaker 1: oldest known specimens found. And there's this one found in 397 00:24:57,800 --> 00:25:00,920 Speaker 1: Utah because apparently Utah used to be a shallow inland 398 00:25:00,960 --> 00:25:04,040 Speaker 1: sea and it had these jellyfish in it. And I 399 00:25:04,080 --> 00:25:07,560 Speaker 1: guess something happened to this jellyfish. It was crushed by 400 00:25:07,880 --> 00:25:11,960 Speaker 1: a rock, something a lot of pressure, I would think, 401 00:25:12,200 --> 00:25:14,399 Speaker 1: but all of a sudden it just captured it. Because 402 00:25:14,440 --> 00:25:17,439 Speaker 1: it's it's like a perfect it's like a drawing of 403 00:25:17,480 --> 00:25:21,760 Speaker 1: the jellyfish in a rock. Um And it's the oldest 404 00:25:21,800 --> 00:25:24,760 Speaker 1: fossil and it's five million years old. So it was 405 00:25:24,800 --> 00:25:28,000 Speaker 1: a pretty lucky find actually to find this, this jellyfish 406 00:25:28,080 --> 00:25:31,320 Speaker 1: that should not have been fossilized, that was fossilized. So 407 00:25:31,560 --> 00:25:35,200 Speaker 1: we do know that there um about two hundred or 408 00:25:35,240 --> 00:25:38,640 Speaker 1: a hundred and fifty million years older than fish fish 409 00:25:38,680 --> 00:25:41,760 Speaker 1: weren't even around by then. Um, and they think that 410 00:25:41,840 --> 00:25:45,520 Speaker 1: possibly sea comb or jelly comb or sorry, comb jellies 411 00:25:46,240 --> 00:25:50,679 Speaker 1: were Um, it's possible they were the earliest animals to 412 00:25:50,760 --> 00:25:55,400 Speaker 1: branch off, even more even earlier than sponges. Well, didn't 413 00:25:55,400 --> 00:25:59,600 Speaker 1: they find that the jellyfish was the first animal in 414 00:25:59,640 --> 00:26:02,879 Speaker 1: the sea that didn't just float along like a dummy, 415 00:26:03,119 --> 00:26:05,359 Speaker 1: that actually used muscles to swim places. Yeah, and it 416 00:26:05,400 --> 00:26:07,720 Speaker 1: was possible it was the comb jellies that did that. 417 00:26:07,960 --> 00:26:10,800 Speaker 1: So it's possible that comb jellies branched off from the 418 00:26:10,800 --> 00:26:13,800 Speaker 1: tree of life, so it's just one type of animal. 419 00:26:14,000 --> 00:26:16,160 Speaker 1: Then all of a sudden, there's a comb jelly. Right, 420 00:26:16,280 --> 00:26:19,199 Speaker 1: what is this black magic you speak of? Right? And 421 00:26:19,200 --> 00:26:22,680 Speaker 1: then maybe the jellyfish at some later point branched off 422 00:26:22,680 --> 00:26:25,639 Speaker 1: of the comb jelly right. Um, But either way, it 423 00:26:25,680 --> 00:26:28,000 Speaker 1: would have been the comb jelly and or the jellyfish 424 00:26:28,040 --> 00:26:31,160 Speaker 1: that were the first to say we're going this way. Yeah, 425 00:26:31,200 --> 00:26:32,720 Speaker 1: you guys are just floating around like a bunch of 426 00:26:32,920 --> 00:26:37,640 Speaker 1: morons waiting for food to hit You were embarrassed for you. Well, 427 00:26:37,640 --> 00:26:42,880 Speaker 1: speaking of food, they are all carnivorous and they eat, 428 00:26:43,400 --> 00:26:46,679 Speaker 1: like you said, they'll eat anything. They love plankton, but 429 00:26:46,760 --> 00:26:50,320 Speaker 1: they eat fish. They eat crustaceans. Some eat other jellyfish, 430 00:26:50,359 --> 00:26:56,119 Speaker 1: which is disgusting. Um, and those uh neumaticist and color blasts, 431 00:26:56,200 --> 00:27:00,880 Speaker 1: the stingers or the glue guns. Um, they are good 432 00:27:00,920 --> 00:27:03,520 Speaker 1: for defense. But uh, there are a hundred and fifty 433 00:27:03,520 --> 00:27:06,960 Speaker 1: animals that also eat the jellies. Fish and sea turtles. 434 00:27:07,720 --> 00:27:11,879 Speaker 1: There's the sunfish loves them. Weather back seat turtles love them. 435 00:27:12,040 --> 00:27:15,360 Speaker 1: They they journey to find them. Yeah, that's how much 436 00:27:15,400 --> 00:27:20,080 Speaker 1: they love them. The Chinese, Yeah, they eat human beings 437 00:27:20,080 --> 00:27:23,760 Speaker 1: eat jellyfish. Yeah. It's apparently a wedding delicacy in China 438 00:27:24,359 --> 00:27:27,640 Speaker 1: and has been for about fifteen sixteen hundred years. Yeah, 439 00:27:28,720 --> 00:27:35,920 Speaker 1: ours is catered salmon in uh chicken Marbella. Uh yeah, 440 00:27:35,960 --> 00:27:39,679 Speaker 1: fo thousand tons of jellyfish are caught each year in 441 00:27:39,760 --> 00:27:43,400 Speaker 1: fifteen countries, mainly in Southeast Asia's where they're eating these. Yeah, 442 00:27:43,480 --> 00:27:46,760 Speaker 1: but um, I read that Georgia, our state of Georgia, 443 00:27:47,600 --> 00:27:52,240 Speaker 1: um has a commercial jellyfish fishery. Really big Gem's jellies 444 00:27:55,000 --> 00:27:58,160 Speaker 1: preserved Moonshina. You totally eat jellyfish? Would sure I would 445 00:27:58,200 --> 00:28:02,480 Speaker 1: try it? Yeah, apparently it's also um it's served in Japan. Too, 446 00:28:02,480 --> 00:28:07,480 Speaker 1: it's salted, which would be good. I would try raw. 447 00:28:07,920 --> 00:28:10,600 Speaker 1: I would try raw jellyfish and sushi or something like that, 448 00:28:10,640 --> 00:28:13,840 Speaker 1: but I would guess that salted strips and jellyfish are 449 00:28:13,840 --> 00:28:18,280 Speaker 1: probably vastly preferable. I'm not nearly as adventurous as you 450 00:28:19,000 --> 00:28:23,720 Speaker 1: with my my mouth and my stomach, but I might 451 00:28:23,840 --> 00:28:27,840 Speaker 1: try jellyfish, even though I'm talking about how much I 452 00:28:27,920 --> 00:28:32,840 Speaker 1: love it. Right, you just cry while you ate? Yeah, exactly. 453 00:28:34,640 --> 00:28:38,720 Speaker 1: You were so beautiful once. Um. Well, I would eat 454 00:28:38,880 --> 00:28:44,760 Speaker 1: um wooly mammoth. Oh yeah, and you like them? Yeah? Uh, 455 00:28:45,160 --> 00:28:47,959 Speaker 1: you gotta bring floss? Would you eat woly mammoth? Supposedly 456 00:28:48,000 --> 00:28:50,920 Speaker 1: that does nothing? Have you heard about that? Oh? Yeah? 457 00:28:51,000 --> 00:28:53,600 Speaker 1: Then the new studies its flossing is no good. Well, 458 00:28:53,640 --> 00:28:55,920 Speaker 1: we talked about that. I think what they said. It 459 00:28:56,000 --> 00:28:58,160 Speaker 1: depends on who you talk to. Some people are saying like, no, 460 00:28:58,280 --> 00:29:00,560 Speaker 1: they just realize that no one's ever done a scientific 461 00:29:00,600 --> 00:29:03,720 Speaker 1: study to back up that flossing is good for you. 462 00:29:04,120 --> 00:29:05,800 Speaker 1: And other people are saying like, no, they did some 463 00:29:05,840 --> 00:29:09,479 Speaker 1: studies and found that it doesn't do anything, which I 464 00:29:09,520 --> 00:29:13,400 Speaker 1: cannot believe. We either just talked about this the last 465 00:29:13,400 --> 00:29:16,440 Speaker 1: recording session, or we talked about it on stage. We 466 00:29:16,520 --> 00:29:18,480 Speaker 1: probably talked about it on stage because it came out 467 00:29:18,520 --> 00:29:20,760 Speaker 1: while we were in the UK. Okay, yeah, all right, 468 00:29:21,000 --> 00:29:25,280 Speaker 1: but the idea that getting rotting food out from between 469 00:29:25,320 --> 00:29:28,840 Speaker 1: your teeth has no positive health benefits for you is 470 00:29:28,960 --> 00:29:32,600 Speaker 1: just it defies explanation. It was on stage because I 471 00:29:32,640 --> 00:29:35,520 Speaker 1: made a crack about missing my teeth. Oh yeah, I 472 00:29:35,520 --> 00:29:39,760 Speaker 1: remember now, uh. Feeding As far as them feeding on 473 00:29:39,800 --> 00:29:42,800 Speaker 1: other things, we talked about these tentacles that they have 474 00:29:42,920 --> 00:29:48,440 Speaker 1: to capture prey and these nematicists. It's amazing these basically 475 00:29:48,480 --> 00:29:53,239 Speaker 1: they're described in the article as venom bearing harpoons. So 476 00:29:53,280 --> 00:29:57,480 Speaker 1: what happens is there's a cue. Uh it's either something 477 00:29:57,520 --> 00:30:00,560 Speaker 1: has touched them or it's a chemical uh que that 478 00:30:00,640 --> 00:30:03,880 Speaker 1: something is around, and they shoot out this little harpoon 479 00:30:04,600 --> 00:30:08,800 Speaker 1: and within seven hundred nana seconds it's spears the prey 480 00:30:08,840 --> 00:30:14,160 Speaker 1: and releases a toxin. Yes, and it's it's frightening. Yeah. 481 00:30:14,320 --> 00:30:18,760 Speaker 1: If you um, if you're a fish, you're in trouble. 482 00:30:18,800 --> 00:30:22,320 Speaker 1: If you're another jellyfish, you're in trouble. Something smaller than 483 00:30:22,320 --> 00:30:25,960 Speaker 1: that you're just totally dead. And depending on the jellyfish, 484 00:30:26,040 --> 00:30:27,960 Speaker 1: if you're a human being, you can die as a 485 00:30:28,000 --> 00:30:30,920 Speaker 1: matter of fact too. Yes, we talk about that, dude. Yeah, 486 00:30:31,160 --> 00:30:34,320 Speaker 1: so the um there's the sea wasp obviously, which has 487 00:30:34,320 --> 00:30:37,360 Speaker 1: the most toxic venom on earth as far as humans 488 00:30:37,400 --> 00:30:40,240 Speaker 1: are concerned. But then there's also another type of um 489 00:30:40,320 --> 00:30:43,560 Speaker 1: box jellyfish that are much tinier. I think they're about 490 00:30:43,560 --> 00:30:46,440 Speaker 1: thumbsized or peanut sized. Yeah, you could. You don't even 491 00:30:46,480 --> 00:30:48,600 Speaker 1: see these things, or if you do see them and 492 00:30:48,640 --> 00:30:50,880 Speaker 1: they brush against you, you're probably not even gonna feel 493 00:30:50,880 --> 00:30:56,480 Speaker 1: the stings called ariicanji, Yeah, which is a an Aboriginal 494 00:30:56,560 --> 00:31:01,080 Speaker 1: word for for this type of jellyfish. Right, there's a 495 00:31:01,160 --> 00:31:05,479 Speaker 1: dude in the sixties, a Westerner who um was like, 496 00:31:05,560 --> 00:31:08,520 Speaker 1: what what is with this jellyfish? I I've heard weird 497 00:31:08,560 --> 00:31:10,400 Speaker 1: things about it. I don't know much about it. I'm 498 00:31:10,440 --> 00:31:12,720 Speaker 1: gonna go out and let myself get stung by one. 499 00:31:12,840 --> 00:31:15,280 Speaker 1: Where did he get killed very easily by something at 500 00:31:15,320 --> 00:31:18,320 Speaker 1: any given point Australia, Yeah, exactly, because they're the ones. 501 00:31:18,360 --> 00:31:20,840 Speaker 1: They've got the sea wasps too, and they have to 502 00:31:20,880 --> 00:31:23,160 Speaker 1: do with the sea wasps. Saying these little guys the 503 00:31:23,320 --> 00:31:26,240 Speaker 1: eru kanji. Is that how we agreed we're gonna say it. Yeah, 504 00:31:26,280 --> 00:31:29,600 Speaker 1: iri kanji Iri kanji. So this guy survived, but he 505 00:31:29,920 --> 00:31:34,240 Speaker 1: um not not well, but he had a hard time 506 00:31:34,320 --> 00:31:37,520 Speaker 1: getting to the point where they're like, you're going to survive. Yeah, 507 00:31:37,560 --> 00:31:40,360 Speaker 1: he was lucky to survive. So you get a sting 508 00:31:40,440 --> 00:31:43,320 Speaker 1: from one of these things, just a single tannicle, apparently 509 00:31:43,320 --> 00:31:47,080 Speaker 1: in about twenty to thirty minutes, what's called ira Kanji 510 00:31:47,120 --> 00:31:50,080 Speaker 1: syndrome starts to sit in and you feel it in 511 00:31:50,080 --> 00:31:52,600 Speaker 1: your lower back first, right, Yeah, and you don't know 512 00:31:52,640 --> 00:31:55,120 Speaker 1: you've been stunk. So you're just like, oh, man, like 513 00:31:55,200 --> 00:31:58,120 Speaker 1: I tweaked my back out there in the ocean, and 514 00:31:58,160 --> 00:32:02,800 Speaker 1: then things really start going south. Then you go and 515 00:32:02,880 --> 00:32:06,440 Speaker 1: throw up your right kidney. Yeah. And this article you 516 00:32:06,560 --> 00:32:09,760 Speaker 1: said said it feels like someone hits you with a 517 00:32:09,760 --> 00:32:12,560 Speaker 1: baseball bat and your kidneys and then comes to nausea 518 00:32:12,640 --> 00:32:15,840 Speaker 1: and vomiting, which continues every minute or so for around 519 00:32:15,840 --> 00:32:20,160 Speaker 1: twelve hours. Yeah. You get spasms in your arms and legs, 520 00:32:20,200 --> 00:32:23,760 Speaker 1: your blood pressure increases, your skin begins to creep. It 521 00:32:23,840 --> 00:32:26,840 Speaker 1: says as if worms are burrowing through it. Yeah. Saw 522 00:32:26,880 --> 00:32:28,880 Speaker 1: I saw a video of a guy who was stung 523 00:32:28,920 --> 00:32:31,400 Speaker 1: and he said it felt like someone was pouring acid 524 00:32:31,440 --> 00:32:34,560 Speaker 1: all over my body. Yea from just being brushed by 525 00:32:34,560 --> 00:32:38,600 Speaker 1: this thumb sized, tiny little jellyfish. And then there's this 526 00:32:38,680 --> 00:32:40,920 Speaker 1: is the creepiest thing to me, says. Victims are often 527 00:32:40,960 --> 00:32:44,280 Speaker 1: gripped with a sense of impending doom and begged their 528 00:32:44,320 --> 00:32:49,080 Speaker 1: doctors to kill them. Yeah, can you imagine. And they're 529 00:32:49,080 --> 00:32:51,640 Speaker 1: spreading their range. Actually they found him off the coast 530 00:32:51,640 --> 00:32:56,520 Speaker 1: of Florida. They found him off the coast of South Africa. Jeez. Yeah, 531 00:32:56,840 --> 00:32:59,600 Speaker 1: So yeah, they're not to be messed with, alright, So 532 00:32:59,680 --> 00:33:02,080 Speaker 1: down with your kanji? Right? Have you ever heard that 533 00:33:02,120 --> 00:33:05,840 Speaker 1: you should pee on somebody who's been stung by a jellyfish? 534 00:33:05,920 --> 00:33:09,000 Speaker 1: I've seen friends, so that's not true. And they've actually 535 00:33:09,040 --> 00:33:12,520 Speaker 1: found that could make it worse. Yeah, but there's actually 536 00:33:12,600 --> 00:33:15,120 Speaker 1: some science to it. Right, So if you get if 537 00:33:15,400 --> 00:33:17,920 Speaker 1: you get stung by a jellyfish, if it's technacle hits you, 538 00:33:18,000 --> 00:33:21,280 Speaker 1: and and you're stung by a nematicist, there may be 539 00:33:21,360 --> 00:33:27,120 Speaker 1: some leftover ones still attached to your arm, right, and 540 00:33:27,160 --> 00:33:29,000 Speaker 1: you want to get rid of those. But if you 541 00:33:29,000 --> 00:33:31,040 Speaker 1: get rid of them, if you pour they just fresh 542 00:33:31,120 --> 00:33:36,520 Speaker 1: water on them, you're gonna trigger You're gonna trigger the 543 00:33:36,520 --> 00:33:40,040 Speaker 1: little harpoons inside because they're held in place by a 544 00:33:40,160 --> 00:33:45,120 Speaker 1: specific concentration of salutes. Right, so if you change that 545 00:33:45,240 --> 00:33:48,000 Speaker 1: concentration by hitting it with freshwater, you're gonna set them off. 546 00:33:48,520 --> 00:33:53,080 Speaker 1: You seawater because they're held in check in seawater normally. 547 00:33:53,400 --> 00:33:55,040 Speaker 1: So you see water to wash it off, and then 548 00:33:55,080 --> 00:33:57,160 Speaker 1: you take a credit card and scrape the rest of 549 00:33:57,200 --> 00:34:01,000 Speaker 1: them off. But some kind of you know, what if 550 00:34:01,040 --> 00:34:02,760 Speaker 1: you if you don't have your credit card on you, 551 00:34:02,800 --> 00:34:05,320 Speaker 1: sure if you're not. But supposedly you're supposed to keep 552 00:34:05,320 --> 00:34:08,399 Speaker 1: sand out of it, which is tough to do. Sure, 553 00:34:08,520 --> 00:34:10,520 Speaker 1: I did the beach. I did it. Don't be dumb 554 00:34:10,560 --> 00:34:14,279 Speaker 1: on it. Years back on the what you do in 555 00:34:14,280 --> 00:34:19,359 Speaker 1: the chair, all sorts of weird stuff you remember, all right, Well, 556 00:34:19,360 --> 00:34:22,960 Speaker 1: getting back to the feeding. Uh, we covered the harpoon. 557 00:34:23,800 --> 00:34:27,040 Speaker 1: Themis of the jelly, but the comb jelly like we 558 00:34:27,080 --> 00:34:30,680 Speaker 1: talked about earlier that um, this is the neumaticis they 559 00:34:30,680 --> 00:34:33,880 Speaker 1: have the glue instead of the venom. So what they 560 00:34:33,920 --> 00:34:35,960 Speaker 1: do is they just send out that fishing line and 561 00:34:36,000 --> 00:34:39,960 Speaker 1: release that sticky glue and it reels whatever it catches 562 00:34:40,080 --> 00:34:43,799 Speaker 1: right on into the mouth. Pretty cool, like something being 563 00:34:43,840 --> 00:34:48,080 Speaker 1: sucked towards the death star. Yeah, exact a tractor beam. 564 00:34:48,080 --> 00:34:51,120 Speaker 1: You got caught in attractor beam. Basically, should we take 565 00:34:51,120 --> 00:34:53,920 Speaker 1: a break. Oh wait, there was one other thing, so 566 00:34:54,080 --> 00:34:57,080 Speaker 1: one type of comb jelly. This is so awesome. They 567 00:34:57,080 --> 00:35:02,160 Speaker 1: actually eat true jellies, and then they take their nomadicists 568 00:35:02,280 --> 00:35:06,440 Speaker 1: and use them for their own hunting. How like? How 569 00:35:06,520 --> 00:35:10,200 Speaker 1: so they think they absorbed them and shoot them out 570 00:35:10,200 --> 00:35:12,759 Speaker 1: in their teammates save them? Yeah, they took him in 571 00:35:12,800 --> 00:35:15,680 Speaker 1: their cheek for later. Can they get an unlimited supply 572 00:35:15,680 --> 00:35:19,399 Speaker 1: of these? I don't know. It's curious if you could 573 00:35:19,400 --> 00:35:22,439 Speaker 1: see one with like three hundred of them. Look, look 574 00:35:22,440 --> 00:35:25,360 Speaker 1: how many I've eaten. It's like, don't be a pig. 575 00:35:25,560 --> 00:35:29,120 Speaker 1: Sure you spit some of those out. Uh now, can 576 00:35:29,160 --> 00:35:31,319 Speaker 1: we take a break? Yes? All right. By the way, 577 00:35:31,360 --> 00:35:34,439 Speaker 1: we just satisfied that one listener because you rejected my break. 578 00:35:35,080 --> 00:35:37,359 Speaker 1: Oh yeah, that's true. How about that man a lie? 579 00:35:37,440 --> 00:35:39,040 Speaker 1: All right, we'll be back and talk a little bit 580 00:35:39,080 --> 00:36:09,160 Speaker 1: about defense. All right, So I promised talk of defense. Um, 581 00:36:09,280 --> 00:36:12,440 Speaker 1: these things you've probably seen, jellyfish and comb jellies that 582 00:36:12,520 --> 00:36:16,799 Speaker 1: produce light, this bioluminescence. Although when I said earlier, the 583 00:36:16,960 --> 00:36:20,080 Speaker 1: comb jelly when it looks colorful, that is not bioluminescence. 584 00:36:20,480 --> 00:36:24,239 Speaker 1: They are still bioluminescent, just not in that way right, 585 00:36:24,400 --> 00:36:27,480 Speaker 1: so confusing. They actually do produce light. Uh, they have 586 00:36:27,560 --> 00:36:30,960 Speaker 1: these proteins that have a chemical reaction to produce this 587 00:36:31,120 --> 00:36:34,879 Speaker 1: blue and green light when something might touch it. And yeah, 588 00:36:34,920 --> 00:36:37,719 Speaker 1: like moon jellies are well known for this. Yeah, and 589 00:36:37,719 --> 00:36:40,920 Speaker 1: they're not exactly sure why, but they think that this 590 00:36:40,960 --> 00:36:45,720 Speaker 1: could be a defensive mechanism to like either scare someone 591 00:36:45,800 --> 00:36:47,440 Speaker 1: trying to eat you by turning a light on their 592 00:36:47,480 --> 00:36:50,520 Speaker 1: face or turning a light on and attracting something larger 593 00:36:50,560 --> 00:36:53,720 Speaker 1: to eat that thing. Either way, they think it's defense. 594 00:36:53,840 --> 00:36:58,520 Speaker 1: And then alternately, some jellyfish have um camouflage actually not 595 00:36:58,680 --> 00:37:01,960 Speaker 1: as good as the US No, no, no, no, not 596 00:37:02,040 --> 00:37:04,680 Speaker 1: at all, but I mean obviously some are are most 597 00:37:04,760 --> 00:37:09,279 Speaker 1: are transparent. It's pretty good camouflage um. And then some 598 00:37:09,360 --> 00:37:12,200 Speaker 1: of the deep sea ones are actually red. They produce 599 00:37:12,239 --> 00:37:16,239 Speaker 1: a red pigment and the red apparently is very very 600 00:37:16,280 --> 00:37:19,279 Speaker 1: difficult to see in deep water, which is like two 601 00:37:20,120 --> 00:37:22,840 Speaker 1: or more where there's no light. Yeah, you think it 602 00:37:22,880 --> 00:37:25,520 Speaker 1: would be black, but they say that the red is 603 00:37:25,560 --> 00:37:28,799 Speaker 1: easier to produce and exactly, so black would work. It's 604 00:37:28,840 --> 00:37:33,840 Speaker 1: just you try making black pigment. You can't and reds 605 00:37:33,840 --> 00:37:36,359 Speaker 1: the same down there. Yeah, it's all black. It's all 606 00:37:36,360 --> 00:37:40,440 Speaker 1: the same. So um, some of them do that, and 607 00:37:40,440 --> 00:37:43,480 Speaker 1: then others have just red pigment in their gut that 608 00:37:43,560 --> 00:37:47,040 Speaker 1: if they eat a bioluminescent organism, it's not going to 609 00:37:47,120 --> 00:37:51,879 Speaker 1: accidentally attract a predator to come check them out. Interesting. See, 610 00:37:52,040 --> 00:37:55,319 Speaker 1: this is really the octopus is threatened in my heart 611 00:37:56,160 --> 00:37:58,879 Speaker 1: still a little bit now that I'm talking about this man, 612 00:37:59,080 --> 00:38:03,000 Speaker 1: it's unstable. We'll see. I'll give a final vote at 613 00:38:03,000 --> 00:38:06,279 Speaker 1: the end. So to me, this is now we get 614 00:38:06,320 --> 00:38:09,799 Speaker 1: to the most amazing part, well, one of the most 615 00:38:09,840 --> 00:38:14,080 Speaker 1: amazing parts about jelly's sexy. Yeah so, which is not 616 00:38:14,160 --> 00:38:18,160 Speaker 1: very sexy, no, although it's like every kind of sex 617 00:38:18,239 --> 00:38:21,600 Speaker 1: you can imagine jellyfish engage in, and not just different 618 00:38:21,640 --> 00:38:29,440 Speaker 1: species like individuals. Some are hermaphroditic, some are sexually divided, 619 00:38:30,400 --> 00:38:34,200 Speaker 1: some are a sexual yep, some yeah, some reproduce a 620 00:38:34,320 --> 00:38:37,799 Speaker 1: sexually sometimes in some species like the moon jelly, I 621 00:38:37,800 --> 00:38:41,680 Speaker 1: believe they'll all get together in one big mass and 622 00:38:41,760 --> 00:38:44,920 Speaker 1: just start swapping sperms and eggs. Yep, spit them out 623 00:38:44,920 --> 00:38:48,680 Speaker 1: of that mouth, hoole. There, get some boxed wine. The 624 00:38:48,760 --> 00:38:52,160 Speaker 1: parties on put on, Michael Bolton, though your house, your 625 00:38:52,360 --> 00:38:56,440 Speaker 1: house keys in a big wooden bowl right now, you 626 00:38:56,480 --> 00:39:01,040 Speaker 1: have it. That's the jellyfish way. Uh So the medusa 627 00:39:01,120 --> 00:39:03,239 Speaker 1: that that you know and love is the main true 628 00:39:03,320 --> 00:39:07,839 Speaker 1: jelly They spawn. So what they do is they release 629 00:39:07,880 --> 00:39:10,160 Speaker 1: a bunch of eggs and sperm into the open ocean 630 00:39:11,800 --> 00:39:16,160 Speaker 1: a lot of times altogether. And they do this from 631 00:39:16,160 --> 00:39:20,479 Speaker 1: their mouth hole and take it in in their mouth hole, 632 00:39:21,440 --> 00:39:24,799 Speaker 1: and uh, the sperm meets the egg and that's how 633 00:39:24,840 --> 00:39:30,200 Speaker 1: it happens. Yeah, ideally or um in some kinds, the uh, 634 00:39:30,680 --> 00:39:34,040 Speaker 1: the eggs stay in the mouth of the female and 635 00:39:34,120 --> 00:39:36,880 Speaker 1: the male just shoots sperm out into the water and 636 00:39:37,160 --> 00:39:40,680 Speaker 1: the sperm find their way into the mouth. It's a 637 00:39:40,680 --> 00:39:44,120 Speaker 1: way to go, yeah, Or they fertilize outside in the water, 638 00:39:44,239 --> 00:39:48,200 Speaker 1: like you were saying. Um. And then in others there 639 00:39:49,120 --> 00:39:53,279 Speaker 1: they don't even necessarily get together. Yeah, they'll just be 640 00:39:53,680 --> 00:39:56,479 Speaker 1: like a pollop will just be sitting there spewing out 641 00:39:57,080 --> 00:40:00,600 Speaker 1: sperm or eggs. Gam eats like a all day long 642 00:40:00,920 --> 00:40:05,520 Speaker 1: huh one one type spews out like forty through forty 643 00:40:05,560 --> 00:40:09,920 Speaker 1: six thousand a day, every day, all the time. Um, 644 00:40:10,160 --> 00:40:13,680 Speaker 1: And then the whole idea is that eventually maybe it'll 645 00:40:13,760 --> 00:40:16,759 Speaker 1: run into another gam eat and fertilize out. That's the 646 00:40:16,760 --> 00:40:19,920 Speaker 1: comb jelly actually, Oh is that a comb that does that? Okay. 647 00:40:20,360 --> 00:40:22,759 Speaker 1: The polyps are the ones that are a sexual and 648 00:40:22,800 --> 00:40:26,440 Speaker 1: they just bud and divide in half basically to produce 649 00:40:26,480 --> 00:40:30,600 Speaker 1: a little identical buddy. And then that can stay a polyp, 650 00:40:30,680 --> 00:40:33,399 Speaker 1: or it can eventually become a medusa. Yeah, because that's 651 00:40:33,440 --> 00:40:36,960 Speaker 1: the thing, like the polyp is a it's a stage 652 00:40:37,239 --> 00:40:40,960 Speaker 1: of a jellyfish, the jellyfish life cycle. It can be 653 00:40:41,120 --> 00:40:45,520 Speaker 1: which can be it? Yeah, you can you can just 654 00:40:45,560 --> 00:40:49,000 Speaker 1: stay a polyp, or you can eventually become a medusa. Yeah, 655 00:40:49,000 --> 00:40:51,920 Speaker 1: And we didn't say that the the Depending on the jellyfish, 656 00:40:51,960 --> 00:40:53,919 Speaker 1: it might live for a few weeks or a year. 657 00:40:54,400 --> 00:40:57,480 Speaker 1: Apparently they do better in captivity and tend to live 658 00:40:57,600 --> 00:41:00,640 Speaker 1: up to several years in captivity. I get the idea. 659 00:41:00,640 --> 00:41:03,880 Speaker 1: They're pretty fragile out there in the ocean. Yeah. Um, 660 00:41:03,920 --> 00:41:08,120 Speaker 1: but they can reproduce so frequently and so early on 661 00:41:08,239 --> 00:41:12,239 Speaker 1: in their life cycle, um that they can populate an 662 00:41:12,280 --> 00:41:16,960 Speaker 1: area very quickly to despite having a very short lifespan. Uh. 663 00:41:17,000 --> 00:41:20,640 Speaker 1: And then in the polyp stage, some species can stay 664 00:41:20,680 --> 00:41:24,239 Speaker 1: there for well, basically almost indefinitely, and just sit there 665 00:41:24,280 --> 00:41:27,480 Speaker 1: and reproduce. There's a type of reproduction in the polyp 666 00:41:27,520 --> 00:41:32,160 Speaker 1: stage where um, it's called strobe lation, and the little 667 00:41:32,160 --> 00:41:35,640 Speaker 1: polyp is sitting there just shooting off these little discs, 668 00:41:36,800 --> 00:41:39,000 Speaker 1: ten to fifteen at a time. And they found that 669 00:41:39,040 --> 00:41:42,680 Speaker 1: depending on the temperature of the water, um, and the 670 00:41:42,760 --> 00:41:46,560 Speaker 1: warmer the water, the more they strobo late um, they'll 671 00:41:46,600 --> 00:41:49,200 Speaker 1: there'll be more and more jellyfish that they just kind 672 00:41:49,200 --> 00:41:51,840 Speaker 1: of shoot off like this article put it like shooting 673 00:41:51,840 --> 00:41:55,279 Speaker 1: off clay pigeons, right, and then each one just transforms 674 00:41:55,280 --> 00:42:02,000 Speaker 1: into a medusa. Man, that's amazing. Octopus. Yeah, it's in trouble. Uh. 675 00:42:02,000 --> 00:42:08,000 Speaker 1: And then oh, this is super cool. The Tautopsis neutricula. 676 00:42:08,400 --> 00:42:12,719 Speaker 1: It is basically immortal. It is a hydrozoan and it 677 00:42:12,760 --> 00:42:16,880 Speaker 1: can actually revert back to the poly up stage after 678 00:42:16,920 --> 00:42:21,800 Speaker 1: the medusa stage through trans differentiation and live forever essentially 679 00:42:21,840 --> 00:42:25,120 Speaker 1: unless it gets killed obviously by something. Uh. And it 680 00:42:25,239 --> 00:42:27,839 Speaker 1: is the only animal that anyone knows of that can 681 00:42:27,880 --> 00:42:34,680 Speaker 1: do this. Yeah, amazing. There's another type of teratopsis to that. Um. 682 00:42:34,760 --> 00:42:39,720 Speaker 1: When it dies, it disintegrates, but it sells some cells 683 00:42:40,920 --> 00:42:46,480 Speaker 1: as it's as it's decaying, come back and form another individual. Yea. 684 00:42:46,600 --> 00:42:51,680 Speaker 1: So it basically fertilizes itself using its dying body and regenerates. 685 00:42:51,840 --> 00:42:56,400 Speaker 1: This is like, yeah, it's tapped into the force. All right. 686 00:42:56,480 --> 00:43:00,239 Speaker 1: So we talked earlier about these jellyfish blooms, um or 687 00:43:00,280 --> 00:43:08,120 Speaker 1: outbreaks or plagues, worms what else. That's okay, Um, it's 688 00:43:08,160 --> 00:43:12,960 Speaker 1: great that these things are proliferating like other species that aren't. 689 00:43:13,320 --> 00:43:15,880 Speaker 1: But it can get out of hand. It can interfere 690 00:43:16,320 --> 00:43:20,720 Speaker 1: with people. Uh, it can interfere with machinery at power 691 00:43:20,760 --> 00:43:25,319 Speaker 1: plants on the coast, cause power outage, outages fisheries. Yeah, 692 00:43:25,360 --> 00:43:26,919 Speaker 1: they can get in the way where people are trying 693 00:43:26,920 --> 00:43:29,520 Speaker 1: to fish for something else. Ah, they're getting their jellyfish. Yeah. 694 00:43:29,560 --> 00:43:33,280 Speaker 1: And there's been examples of all this stuff happening over time, 695 00:43:33,320 --> 00:43:36,759 Speaker 1: Like they shut down the USS Ronald Reagan once, which 696 00:43:36,760 --> 00:43:40,399 Speaker 1: is a nuclear powered warship, because it got a bunch 697 00:43:40,400 --> 00:43:43,919 Speaker 1: of jellyfish got sucked up into the cooling system. Um. 698 00:43:44,040 --> 00:43:48,920 Speaker 1: They've shut down power plants in India, in Japan, in 699 00:43:49,000 --> 00:43:54,080 Speaker 1: the Philippines. Um. And they think there's there's if there's 700 00:43:54,120 --> 00:43:58,360 Speaker 1: a debate over whether comb jellies and jellyfish are related. 701 00:43:58,800 --> 00:44:03,240 Speaker 1: There's a huge bait over whether or not we're seeing 702 00:44:03,239 --> 00:44:10,320 Speaker 1: a natural outcome of uh, just jellyfish life cycles blooms, 703 00:44:10,440 --> 00:44:12,920 Speaker 1: like this is just happening. Yeah, is this a normal 704 00:44:13,000 --> 00:44:16,399 Speaker 1: thing or are we humans contributing to it? And if 705 00:44:16,440 --> 00:44:19,680 Speaker 1: we humans are contributing to it, they basically say, there's 706 00:44:19,719 --> 00:44:22,759 Speaker 1: probably one of four ways that this is happening. Yeah. 707 00:44:22,760 --> 00:44:27,919 Speaker 1: One of them is overfishing basically just less competition for food. Uh. 708 00:44:27,960 --> 00:44:32,520 Speaker 1: They they're eating this zooplankton, and if other fish that 709 00:44:32,680 --> 00:44:35,600 Speaker 1: normally eat that aren't there, then the jellyfish like sweet 710 00:44:35,800 --> 00:44:39,480 Speaker 1: more for me, think buffet open. Apparently jellyfish students are 711 00:44:39,520 --> 00:44:44,120 Speaker 1: not known to go on diets. They just gorge themselves constantly. 712 00:44:44,160 --> 00:44:48,799 Speaker 1: Really Yeah, what else nutrients? Yeah, when we uh, when 713 00:44:48,840 --> 00:44:53,960 Speaker 1: we release fertilizers from crop land in two areas where 714 00:44:54,040 --> 00:44:57,839 Speaker 1: jellyfish live, we can cause algia blooms. It runs off 715 00:44:57,840 --> 00:45:00,480 Speaker 1: eventually into the sea. Yeah, and it I actually can 716 00:45:00,520 --> 00:45:04,480 Speaker 1: deplete oxygen. So there's two things. One, you've got a 717 00:45:04,640 --> 00:45:08,640 Speaker 1: bunch of zooplankton and phytoplankton, which, um, well, I guess 718 00:45:08,680 --> 00:45:12,839 Speaker 1: they're eating the zooplankton that jellyfish eat, right, and then 719 00:45:13,080 --> 00:45:16,759 Speaker 1: you have lower oxygen, which jellyfish can live in and 720 00:45:16,840 --> 00:45:20,440 Speaker 1: survive in a lot more easily because again they have 721 00:45:20,520 --> 00:45:24,560 Speaker 1: a much lower metabolism than most other organisms that they're 722 00:45:24,600 --> 00:45:28,959 Speaker 1: competing for food with. So their competition again is dying off. 723 00:45:29,640 --> 00:45:32,359 Speaker 1: While they're just like, this is great, I'll just keep 724 00:45:32,360 --> 00:45:35,080 Speaker 1: eating moral they thank you humans for putting all this 725 00:45:35,200 --> 00:45:37,880 Speaker 1: nitrogen and phosphorus in the water. You start to get 726 00:45:37,920 --> 00:45:39,719 Speaker 1: the idea why these things have been around for five 727 00:45:40,160 --> 00:45:43,920 Speaker 1: seven hundred million years. They can compete uh climate change 728 00:45:44,200 --> 00:45:47,600 Speaker 1: with the warming ocean. UM. Some of those jellies love it. UH. 729 00:45:47,640 --> 00:45:50,680 Speaker 1: Their embryos and larvae developed better and more quickly, so 730 00:45:50,760 --> 00:45:54,279 Speaker 1: the populations grow more quickly, and a lot of them 731 00:45:54,280 --> 00:45:58,239 Speaker 1: prefer that warmer water, so they say bring it on, yeah, 732 00:45:58,280 --> 00:46:01,799 Speaker 1: and they're actually like it's There was at least one 733 00:46:01,840 --> 00:46:06,480 Speaker 1: study that UM looked at how jellyfish reproduced in warmer 734 00:46:06,520 --> 00:46:11,359 Speaker 1: water and also water that's of higher acidity, which they're 735 00:46:11,360 --> 00:46:16,080 Speaker 1: predicting through ocean acidification UM, which is the result of 736 00:46:16,160 --> 00:46:20,040 Speaker 1: higher c O two increases, and both of those suggests 737 00:46:20,040 --> 00:46:22,360 Speaker 1: that jellyfish are going to do just fine under the 738 00:46:22,440 --> 00:46:25,680 Speaker 1: climate change that we're facing. So cockroaches and jellyfish are 739 00:46:25,719 --> 00:46:28,600 Speaker 1: the only things that are going to be around one day. Uh. 740 00:46:28,640 --> 00:46:33,480 Speaker 1: And then finally what they call ocean sprawl. Um, it's 741 00:46:33,520 --> 00:46:35,439 Speaker 1: you know what, we're building things out in the middle 742 00:46:35,440 --> 00:46:41,040 Speaker 1: of the ocean now, drilling platforms and docks and oil platforms. Uh, 743 00:46:41,600 --> 00:46:46,279 Speaker 1: hard structures and jellyfish. The polyps especially that we were 744 00:46:46,280 --> 00:46:50,240 Speaker 1: talking about that they attached to something sand or Cheryl 745 00:46:50,320 --> 00:46:54,160 Speaker 1: lads belly button is not the easiest thing to attach to. Oh, 746 00:46:54,239 --> 00:46:56,880 Speaker 1: Cheryl lad was born without a belly button. That's the 747 00:46:57,000 --> 00:47:00,240 Speaker 1: claim to faint. That was very insensitive of me. Uh, 748 00:47:02,239 --> 00:47:05,279 Speaker 1: you just threw me there. So what they do love 749 00:47:05,320 --> 00:47:08,480 Speaker 1: to attach to is something solid, So they love, Um, 750 00:47:08,719 --> 00:47:11,959 Speaker 1: they love attaching onto the ocean sprawl and oil rigs 751 00:47:11,960 --> 00:47:13,600 Speaker 1: and whatever else is out there, and they do very 752 00:47:13,600 --> 00:47:17,040 Speaker 1: well attached to a firm uh. Not the cher Lads 753 00:47:17,239 --> 00:47:21,560 Speaker 1: belly button isn't firm. It's done existing, certainly not an 754 00:47:21,600 --> 00:47:26,720 Speaker 1: iron girder. So. Um, there's this really great story about 755 00:47:27,200 --> 00:47:31,880 Speaker 1: jellyfish and just how quickly they can take over right Um, 756 00:47:31,880 --> 00:47:36,200 Speaker 1: in the Black Sea. When a ship releases its cargo, 757 00:47:36,440 --> 00:47:40,520 Speaker 1: is it off the coast of Germany. Yeah, No, that's 758 00:47:40,560 --> 00:47:43,080 Speaker 1: the North and the Baltic. Okay, don't try and screw 759 00:47:43,120 --> 00:47:45,520 Speaker 1: me up here. This is the Black Sea where they 760 00:47:45,520 --> 00:47:51,320 Speaker 1: make caviar, right, um, And actually there's some like entire 761 00:47:51,480 --> 00:47:55,400 Speaker 1: national economies are based on things like caviar and um, 762 00:47:55,640 --> 00:47:59,840 Speaker 1: sardines and anchovies and just all these amazing fish. And 763 00:48:00,360 --> 00:48:04,360 Speaker 1: this ship apparently took on some seawater after it released 764 00:48:04,360 --> 00:48:08,160 Speaker 1: its cargo to keep itself stable, right, And when it 765 00:48:08,200 --> 00:48:10,719 Speaker 1: got to the Black Sea, it released it. And one 766 00:48:10,719 --> 00:48:13,200 Speaker 1: of the things that released was this type of jellyfish 767 00:48:13,239 --> 00:48:17,560 Speaker 1: called the sea walnut. And this is a two sounds cute. 768 00:48:17,760 --> 00:48:19,680 Speaker 1: So the first sea walnut makes its way into the 769 00:48:19,680 --> 00:48:24,600 Speaker 1: Black Sea. In two thousand two, the total biomass of 770 00:48:24,719 --> 00:48:28,400 Speaker 1: sea walnuts in the Black Sea, just the Black Sea, 771 00:48:28,880 --> 00:48:33,640 Speaker 1: was ten times the total biomass of all the fish 772 00:48:34,040 --> 00:48:37,600 Speaker 1: that were taken from the world's oceans by commercial fishing. 773 00:48:39,040 --> 00:48:43,239 Speaker 1: It got jellyfied, basically, Yeah. And they were competing with um, 774 00:48:43,800 --> 00:48:47,520 Speaker 1: the the the other fish for the zooplankton and the 775 00:48:47,560 --> 00:48:50,160 Speaker 1: food source and winning big time. And so all these 776 00:48:50,200 --> 00:48:53,000 Speaker 1: fisheries collapsed, all these economies were in trouble, and then 777 00:48:53,239 --> 00:48:56,080 Speaker 1: it just so happened that some other ship had picked 778 00:48:56,160 --> 00:48:58,560 Speaker 1: up a different type of jellyfish that actually was a 779 00:48:58,640 --> 00:49:00,879 Speaker 1: natural predator of the sea wall all night and came 780 00:49:00,920 --> 00:49:03,960 Speaker 1: along and saved the day totally by a stroke of luck. 781 00:49:04,080 --> 00:49:08,600 Speaker 1: To see walnut cracker. Yeah, yep, I did see that. 782 00:49:08,640 --> 00:49:11,160 Speaker 1: Actually you sent me that. That's amazing. Yep. So it 783 00:49:11,200 --> 00:49:14,720 Speaker 1: all worked out. Everything about jellyfish is amazing. Yeah, final 784 00:49:14,800 --> 00:49:24,520 Speaker 1: score for me octopus one jellyfish. Whoa, that is close. 785 00:49:24,680 --> 00:49:27,040 Speaker 1: It is nice. Just one three pointer at the end 786 00:49:27,080 --> 00:49:31,960 Speaker 1: could have won it, but it didn't. Nope, it rimmed out. 787 00:49:32,520 --> 00:49:35,719 Speaker 1: So if you want to know more you got anything else? Nope. 788 00:49:35,800 --> 00:49:38,600 Speaker 1: You want to know more about jellyfish and comb jellies 789 00:49:38,640 --> 00:49:40,760 Speaker 1: and that kind of stuff, You can type those words 790 00:49:40,760 --> 00:49:43,359 Speaker 1: into the search part how stuff works dot com. And 791 00:49:43,640 --> 00:49:48,520 Speaker 1: since I said search parts time for listener mail, that's right, 792 00:49:48,560 --> 00:49:51,799 Speaker 1: it's three pm, which means, uh, our bedtime is just 793 00:49:51,880 --> 00:49:57,560 Speaker 1: in about four short hours. Um. I actually tried to 794 00:49:57,600 --> 00:49:59,440 Speaker 1: go to bed before my one year old daughter the 795 00:49:59,480 --> 00:50:03,400 Speaker 1: other night. Yeah, and I said, no, that's bad parenting. 796 00:50:03,560 --> 00:50:07,000 Speaker 1: Sure you just so you put yourself to bed. Oh wait, 797 00:50:07,000 --> 00:50:08,880 Speaker 1: And she finally drifted off at like a thirty and 798 00:50:08,920 --> 00:50:11,960 Speaker 1: I was out at eight thirty two. Um, all right, 799 00:50:12,360 --> 00:50:16,360 Speaker 1: I'm gonna call this you help me get married? Hey, guys, 800 00:50:16,360 --> 00:50:20,000 Speaker 1: so recently got married to my beautiful wife, congratulations, with 801 00:50:20,040 --> 00:50:22,360 Speaker 1: whom I've been with for over eight years. While the 802 00:50:22,400 --> 00:50:25,520 Speaker 1: prospect of being married to her never frightened me at all, 803 00:50:25,600 --> 00:50:27,600 Speaker 1: the thought of having to be in the center of attention, 804 00:50:28,080 --> 00:50:31,080 Speaker 1: professing my love to my then fiance in front of 805 00:50:31,120 --> 00:50:32,600 Speaker 1: all of our guests and try not to look like 806 00:50:32,640 --> 00:50:37,240 Speaker 1: a dummy during the ceremony was how do you say, nauseatingly, frightening, terrifying. 807 00:50:37,239 --> 00:50:41,719 Speaker 1: Excuse me, Um, yeah, Stephen was not He's not a 808 00:50:41,719 --> 00:50:44,919 Speaker 1: public speaker, I don't think. However, during the hours leading 809 00:50:45,000 --> 00:50:46,920 Speaker 1: up to the ceremony, I kept my mind occupied by 810 00:50:46,960 --> 00:50:50,239 Speaker 1: listening to the melodious tones of your voices teaching me 811 00:50:50,280 --> 00:50:53,640 Speaker 1: about well, some things I really don't remember. Honestly, I 812 00:50:53,680 --> 00:50:56,640 Speaker 1: was a little occupied.
