1 00:00:01,200 --> 00:00:04,640 Speaker 1: Welcome to Stuff you Should Know from House Stuff Works 2 00:00:04,680 --> 00:00:14,120 Speaker 1: dot com. Hey, and welcome to the podcast. I'm Josh 3 00:00:14,200 --> 00:00:18,920 Speaker 1: Clark with Charles W. Chuck Bryant, Jerry, Jerome Roland, just 4 00:00:18,960 --> 00:00:22,040 Speaker 1: the whole the whole House Stuff Works gang here to 5 00:00:22,120 --> 00:00:25,640 Speaker 1: present to you stuff you should know, all three of us. 6 00:00:27,440 --> 00:00:32,000 Speaker 1: Are you doing good? Yeah? Yeah, Oh I'm a little caffeinated. 7 00:00:32,040 --> 00:00:34,840 Speaker 1: I should warn you a little bit, like when teeth 8 00:00:34,880 --> 00:00:36,720 Speaker 1: are about to just come right out of my face. 9 00:00:36,880 --> 00:00:40,280 Speaker 1: That's not good. Uh. You know, we did a video 10 00:00:40,280 --> 00:00:43,199 Speaker 1: about Cela Cants one time. Yeah, like was it this 11 00:00:43,280 --> 00:00:46,400 Speaker 1: day in history about when they were discovered. I ran 12 00:00:46,440 --> 00:00:49,239 Speaker 1: across it because it smacked is familiar to me, and 13 00:00:49,360 --> 00:00:52,120 Speaker 1: you know, the constant fear we have of recording an 14 00:00:52,520 --> 00:00:56,200 Speaker 1: entire podcast over uh is sort of always there. Yeah, 15 00:00:56,200 --> 00:01:00,280 Speaker 1: the fear that sometimes comes true. Yeah. So I definitely 16 00:01:00,320 --> 00:01:01,960 Speaker 1: went back and looked, and I was like, I new 17 00:01:01,960 --> 00:01:05,039 Speaker 1: we did something. Yeah, we were trapped in a shipping container, right. 18 00:01:05,720 --> 00:01:08,479 Speaker 1: I didn't watch it. I didn't either enough to say, 19 00:01:08,480 --> 00:01:11,959 Speaker 1: oh yeah I remember that. Yeah, that really weird, weird 20 00:01:12,120 --> 00:01:14,360 Speaker 1: thing we did. But this is really cool. I think 21 00:01:15,080 --> 00:01:18,760 Speaker 1: I need to Seela Cants were um, well they're interesting, 22 00:01:20,080 --> 00:01:23,360 Speaker 1: despite what the House Stuff Works article would lead you 23 00:01:23,440 --> 00:01:26,440 Speaker 1: to believe. It was. Yeah, it was a little thin, 24 00:01:26,560 --> 00:01:30,040 Speaker 1: was a little bit. It was all right. But luckily 25 00:01:30,080 --> 00:01:32,560 Speaker 1: the rest of the Internet is there for us. Right, 26 00:01:33,959 --> 00:01:38,319 Speaker 1: thanks especially to Smithsonian and mental Floss for this one. Right, Yeah, 27 00:01:38,440 --> 00:01:41,440 Speaker 1: that mental plus article is kind of neat, actually it was. 28 00:01:42,080 --> 00:01:46,800 Speaker 1: So you want to go back to the beginning, actually 29 00:01:46,840 --> 00:01:50,760 Speaker 1: the second beginning. Maybe, Well, I don't know what you're 30 00:01:50,760 --> 00:01:54,840 Speaker 1: talking about now, so just okay, Well we'll go back 31 00:01:54,840 --> 00:01:57,080 Speaker 1: to the very beginning. We'll go back to something about 32 00:01:57,080 --> 00:02:02,240 Speaker 1: four million years ago, doing the Devonian period, which is 33 00:02:02,280 --> 00:02:05,520 Speaker 1: a k a. The Rise of the Fish the Age 34 00:02:05,520 --> 00:02:09,280 Speaker 1: of the Fish, right, And in this Devonian period, there's 35 00:02:09,320 --> 00:02:12,680 Speaker 1: a lot a lot of stuff going on. Things have 36 00:02:12,760 --> 00:02:16,000 Speaker 1: been swimming around for a while on Earth. There's a 37 00:02:16,120 --> 00:02:19,320 Speaker 1: nice atmosphere that's developed. The things in the ocean are 38 00:02:19,360 --> 00:02:21,760 Speaker 1: starting to say, oh, what's out there? I want to 39 00:02:21,760 --> 00:02:24,519 Speaker 1: see what's on land. I want to just crawl out 40 00:02:24,680 --> 00:02:28,919 Speaker 1: and see. Yeah, I want to taste clover. So they 41 00:02:28,919 --> 00:02:32,600 Speaker 1: start trying. And during this period there was the progression 42 00:02:32,840 --> 00:02:37,240 Speaker 1: from the sea to the land, and one of those 43 00:02:37,280 --> 00:02:41,480 Speaker 1: things that was starting to develop legs to get onto 44 00:02:41,600 --> 00:02:46,520 Speaker 1: land was called the Ceila cant yeah, which um A 45 00:02:46,880 --> 00:02:51,119 Speaker 1: it means hollow spine, which is we'll get to there's 46 00:02:51,120 --> 00:02:55,080 Speaker 1: a reason for that. And B it's spelled c O 47 00:02:55,480 --> 00:02:59,240 Speaker 1: E l A c A n t h, which is uh, 48 00:03:00,240 --> 00:03:02,040 Speaker 1: you know, not how you would think it might be 49 00:03:02,080 --> 00:03:06,679 Speaker 1: spelled or pronounced rather either one. But it's sela camp. 50 00:03:06,840 --> 00:03:09,280 Speaker 1: It is sela can uh. And what it is is 51 00:03:09,320 --> 00:03:13,440 Speaker 1: a fish that is um, like you said, been around 52 00:03:13,440 --> 00:03:16,200 Speaker 1: for a long long time. It's um kind of funny looking. 53 00:03:16,880 --> 00:03:19,359 Speaker 1: And we'll get into all the physical characteristics that make 54 00:03:19,360 --> 00:03:23,799 Speaker 1: it unusual uh in a sec. But it is notable, uh, 55 00:03:24,040 --> 00:03:28,400 Speaker 1: mainly for the fact that everyone thought it was gone 56 00:03:28,480 --> 00:03:33,160 Speaker 1: forever until it was suddenly discovered. This thing that that 57 00:03:33,280 --> 00:03:37,320 Speaker 1: swam with the dinosaurs was discovered a new in the 58 00:03:37,400 --> 00:03:40,520 Speaker 1: nineteen thirties and then again a little bit later on. Yeah, 59 00:03:40,600 --> 00:03:44,080 Speaker 1: because it was it pops up for the first time 60 00:03:44,120 --> 00:03:47,520 Speaker 1: around um, four hundred and seven million years ago, I think, 61 00:03:47,520 --> 00:03:51,720 Speaker 1: I said, and and then it just drops off eighty 62 00:03:51,800 --> 00:03:54,080 Speaker 1: million years ago. So they said, well, a lot of 63 00:03:54,120 --> 00:03:57,880 Speaker 1: stuff when the way of the dinosaur around the time 64 00:03:57,880 --> 00:04:01,400 Speaker 1: the dinosaurs went away. Um, so that's probably what happened 65 00:04:01,400 --> 00:04:04,440 Speaker 1: to the Cela can't, so it was quite a big surprise. 66 00:04:04,480 --> 00:04:09,200 Speaker 1: In the nineteen thirties when a trawler um that was 67 00:04:09,200 --> 00:04:12,560 Speaker 1: out fishing, a trawler called the Narine which is keptain 68 00:04:12,640 --> 00:04:17,800 Speaker 1: by Hendrik Goossen off the coast of South Africa, came 69 00:04:17,839 --> 00:04:22,200 Speaker 1: in and as was Captain Goosen's want, he contacted the 70 00:04:22,240 --> 00:04:25,599 Speaker 1: director of the local museum in East London, woman named 71 00:04:25,600 --> 00:04:29,880 Speaker 1: Miss Marjorie Courtney Latimer, and she used to come over 72 00:04:29,920 --> 00:04:32,000 Speaker 1: and look at the fish loads this guy would bring 73 00:04:32,000 --> 00:04:35,040 Speaker 1: in because they were buddies and he's He gave her 74 00:04:35,040 --> 00:04:36,840 Speaker 1: a call like normal and said, I got to load 75 00:04:36,880 --> 00:04:38,720 Speaker 1: you want to come look at it? And she was like, 76 00:04:38,839 --> 00:04:42,040 Speaker 1: it's two days before Christmas and his blazing hot out. 77 00:04:42,800 --> 00:04:45,640 Speaker 1: Don't forget where in South Africa at the time, and 78 00:04:45,680 --> 00:04:49,279 Speaker 1: she's like, I don't feel like it. But the world 79 00:04:49,839 --> 00:04:54,600 Speaker 1: was saved, the world of ich theology was saved this 80 00:04:54,680 --> 00:04:59,600 Speaker 1: day because this lady Marjorie Courtney Latimer was so nice 81 00:05:00,440 --> 00:05:02,640 Speaker 1: that she decided to go look at the fish anyway, 82 00:05:02,880 --> 00:05:05,800 Speaker 1: just to wish the captain and his crew a merry Christmas. 83 00:05:05,880 --> 00:05:09,279 Speaker 1: So she takes a look at this fish and here 84 00:05:09,360 --> 00:05:13,359 Speaker 1: is her quote. Uh as she recounted. It wasn't her 85 00:05:13,400 --> 00:05:15,320 Speaker 1: quote at the time or quote at the time, it's 86 00:05:15,360 --> 00:05:20,240 Speaker 1: probably a South African expletive, but she said later I 87 00:05:20,279 --> 00:05:23,159 Speaker 1: picked away the layers of slime to reveal the most 88 00:05:23,160 --> 00:05:26,640 Speaker 1: beautiful fish I had ever seen. Uh. And of course 89 00:05:26,680 --> 00:05:29,960 Speaker 1: only a fish lover can find this thing truly beautiful, 90 00:05:30,320 --> 00:05:33,400 Speaker 1: because it's kind of ugly. It was five ft long, 91 00:05:33,520 --> 00:05:37,440 Speaker 1: a pale mauve blue with faint flecks of whitish spots 92 00:05:37,480 --> 00:05:41,040 Speaker 1: that had an iridescent silver blue green sheen all over. 93 00:05:41,440 --> 00:05:43,479 Speaker 1: It was covered in hard scales, and it had four 94 00:05:43,600 --> 00:05:47,320 Speaker 1: limb like fins and a strange little puppy dog tail. 95 00:05:48,279 --> 00:05:51,880 Speaker 1: Uh not literally, of course. Uh, it was such which 96 00:05:51,880 --> 00:05:55,039 Speaker 1: would be great though actually that's the dog fish that 97 00:05:55,080 --> 00:05:57,280 Speaker 1: has that. It was such a beautiful fish, more like 98 00:05:57,360 --> 00:05:59,800 Speaker 1: a big China ornament. But I didn't know what it was. 99 00:06:00,800 --> 00:06:04,080 Speaker 1: And um, it was pretty faithful that she was called 100 00:06:04,080 --> 00:06:07,719 Speaker 1: in uh to look at this thing, because it ended 101 00:06:07,800 --> 00:06:11,200 Speaker 1: up being one of the most important zoological finds of 102 00:06:11,440 --> 00:06:14,400 Speaker 1: you know, history, probably of the twentieth century at least 103 00:06:14,720 --> 00:06:21,440 Speaker 1: for sure. Yeah, this woman's curiosity, Um, something in her said, 104 00:06:21,480 --> 00:06:24,000 Speaker 1: this is weird, this is unusual, this is this is 105 00:06:24,080 --> 00:06:27,080 Speaker 1: something worth looking into. So she took it with her. 106 00:06:27,480 --> 00:06:30,880 Speaker 1: This thing was like five ft long, just under two ms, 107 00:06:31,120 --> 00:06:34,200 Speaker 1: about a hundred and how many pounds seven pounds. This 108 00:06:34,240 --> 00:06:39,120 Speaker 1: is a significant fish and uh ms, Courtney Latimer talked 109 00:06:39,240 --> 00:06:41,680 Speaker 1: her way into a cab with it. She took a 110 00:06:41,760 --> 00:06:45,040 Speaker 1: cab back to the East London Museum with this fish 111 00:06:45,279 --> 00:06:48,960 Speaker 1: stuffed in the back seat. And um, she took it 112 00:06:49,000 --> 00:06:52,880 Speaker 1: to the taxidermist and had it stuffed. Unfortunately, the taxidermist 113 00:06:52,960 --> 00:06:56,440 Speaker 1: wasn't completely aware of how to preserve a fish for 114 00:06:56,640 --> 00:07:00,080 Speaker 1: identification and throughout the skeleton and the gills, which to 115 00:07:00,480 --> 00:07:05,120 Speaker 1: what you need for for um the idea fish. Apparently, well, 116 00:07:05,160 --> 00:07:09,160 Speaker 1: she probably should have said something. Well she she like, 117 00:07:09,240 --> 00:07:13,320 Speaker 1: this is no ordinary mount. Yeah, right, she probably should have, 118 00:07:13,800 --> 00:07:16,440 Speaker 1: or maybe she did, and he just ignored her. He's like, 119 00:07:16,480 --> 00:07:20,600 Speaker 1: I'm not getta get boss dround by one. So she 120 00:07:20,720 --> 00:07:24,800 Speaker 1: contacts a guy named j. LB. Smith who is an 121 00:07:24,800 --> 00:07:27,640 Speaker 1: ich theologist. He's the head of the ichthyology department at 122 00:07:27,680 --> 00:07:32,960 Speaker 1: the university in Graham's Town and PhD in chemistry. Um, 123 00:07:33,000 --> 00:07:36,680 Speaker 1: he's a smart guy and he's the local fish expert 124 00:07:36,680 --> 00:07:39,320 Speaker 1: as far as she knows. Yeah, and their their pals, 125 00:07:39,360 --> 00:07:42,360 Speaker 1: and so she said, hey, I've got this. Uh, we're 126 00:07:42,360 --> 00:07:45,840 Speaker 1: looking fish. And then Smith his quote was, I told 127 00:07:45,880 --> 00:07:48,600 Speaker 1: myself sternly not to be a fool, but there was 128 00:07:48,640 --> 00:07:52,720 Speaker 1: something about that sketch uh, and apparently it was it 129 00:07:52,800 --> 00:07:54,600 Speaker 1: was sketched. She sent him a sketch of the fish 130 00:07:54,680 --> 00:07:58,440 Speaker 1: to begin with. Uh that seized upon my imagination and 131 00:07:58,480 --> 00:08:00,840 Speaker 1: told me that this was something very far beyond the 132 00:08:00,960 --> 00:08:04,480 Speaker 1: usual run of fishes in our seas. Uh. And luckily, 133 00:08:04,600 --> 00:08:08,360 Speaker 1: even though the fish was um um, I guess mounted 134 00:08:08,400 --> 00:08:10,800 Speaker 1: in a traditional form, which, like you said, takes away. 135 00:08:10,840 --> 00:08:13,720 Speaker 1: It's how you can identify it. She was able to 136 00:08:14,080 --> 00:08:18,040 Speaker 1: preserve some of the scales, and somehow from these scales 137 00:08:18,080 --> 00:08:21,080 Speaker 1: he was able to say, this is a Cola Cant 138 00:08:21,320 --> 00:08:23,720 Speaker 1: Seela canth. Well that's what he said at first, and 139 00:08:23,760 --> 00:08:27,560 Speaker 1: she was pronounce Cela can't. He's like, oh, apparently he 140 00:08:27,600 --> 00:08:30,240 Speaker 1: said when he saw that scale and I and identified 141 00:08:30,280 --> 00:08:33,079 Speaker 1: it positively as a Steela Cant. His quote was, if 142 00:08:33,080 --> 00:08:35,400 Speaker 1: I'd bet a dinosaur in the street, I wouldn't have 143 00:08:35,440 --> 00:08:40,719 Speaker 1: been more astonished. I like that guy. A little hyperbole there, 144 00:08:40,720 --> 00:08:43,000 Speaker 1: but I like it so he um, I mean, this 145 00:08:43,080 --> 00:08:45,520 Speaker 1: is seriously, this is like the zoological find of the 146 00:08:45,559 --> 00:08:48,480 Speaker 1: century and would be for the next sixties something years. 147 00:08:49,360 --> 00:08:53,760 Speaker 1: So he very magnanimously said, you know what, I'm going 148 00:08:53,840 --> 00:08:57,720 Speaker 1: to name this thing after you, and he named it 149 00:08:57,760 --> 00:09:04,559 Speaker 1: as a new species. Let him marry Chilumny because, um, well, 150 00:09:04,600 --> 00:09:09,280 Speaker 1: obviously her name is Courtney Latimer, Courtney hyphen Latimer. And 151 00:09:09,559 --> 00:09:12,920 Speaker 1: it was found in the Chilumna River at the mouth 152 00:09:12,960 --> 00:09:15,960 Speaker 1: of it where it hits the coast off the eastern 153 00:09:16,120 --> 00:09:19,440 Speaker 1: coast of South Africa. So that's a great name. It's 154 00:09:19,720 --> 00:09:23,760 Speaker 1: it's perfect. It really puts it in a place in time. Uh. 155 00:09:23,840 --> 00:09:27,079 Speaker 1: So they have now discovered this thing. They realized that 156 00:09:27,440 --> 00:09:29,280 Speaker 1: they have a big find on their hands. Um. They 157 00:09:29,280 --> 00:09:33,040 Speaker 1: thought this thing had long been extinct by tens of 158 00:09:33,120 --> 00:09:37,880 Speaker 1: millions of years. Uh. And so they started to research 159 00:09:38,240 --> 00:09:41,000 Speaker 1: and you know, try and learn more about this fish. Yeah, 160 00:09:41,360 --> 00:09:44,520 Speaker 1: which is no ordinary fish. No, but I mean this 161 00:09:44,600 --> 00:09:48,319 Speaker 1: was so this is right, and it was the only 162 00:09:48,360 --> 00:09:53,160 Speaker 1: one that had been found for another sixty years. Yeah, 163 00:09:53,640 --> 00:09:55,560 Speaker 1: I mean, there's only so much you can find from 164 00:09:55,600 --> 00:10:00,040 Speaker 1: a stuffed fish. But it did prove because it have 165 00:10:00,160 --> 00:10:02,560 Speaker 1: been caught alive. It wasn't like they pulled up a 166 00:10:02,600 --> 00:10:05,040 Speaker 1: fossil or a dead fish. It had been alive when 167 00:10:05,040 --> 00:10:07,320 Speaker 1: it was caught. Yeah, I think it was attached to 168 00:10:07,360 --> 00:10:11,599 Speaker 1: another fish, like potentially trying to eat it, which is 169 00:10:11,640 --> 00:10:15,360 Speaker 1: one of the uh well, not unusual but interesting things 170 00:10:15,400 --> 00:10:18,720 Speaker 1: about the Cela canth is that it's a it eats meat. Well, 171 00:10:18,720 --> 00:10:22,760 Speaker 1: there's a lot of unusual things about the Cela camp um. 172 00:10:22,800 --> 00:10:28,200 Speaker 1: So fast forward another sixty years exactly um in Indonesia, 173 00:10:28,400 --> 00:10:30,520 Speaker 1: which is on the other side of the Indian Ocean, 174 00:10:30,559 --> 00:10:34,240 Speaker 1: the eastern side of the Indian Ocean. It was actually 175 00:10:34,320 --> 00:10:37,959 Speaker 1: first seen in by a biologist named Mark Erdmann who 176 00:10:38,000 --> 00:10:41,240 Speaker 1: was in Indonesia doing his PhD dissertation, and he saw 177 00:10:41,280 --> 00:10:44,640 Speaker 1: a Cela cant in the market. That's crazy, that's a 178 00:10:44,720 --> 00:10:47,920 Speaker 1: sela can't what's that doing here? So apparently he put 179 00:10:47,960 --> 00:10:50,480 Speaker 1: a bit of a bounty out on it with the locals, 180 00:10:50,880 --> 00:10:55,440 Speaker 1: and within a year by they had brought him freshly 181 00:10:55,559 --> 00:11:00,480 Speaker 1: caught one, which is quite a task. Yeah, it's finding 182 00:11:00,520 --> 00:11:05,920 Speaker 1: a uh once thought extinct fish. Yeah, it's a big one. Well, 183 00:11:05,960 --> 00:11:07,880 Speaker 1: and we'll get to a little bit why. It's even 184 00:11:08,040 --> 00:11:10,840 Speaker 1: tougher than you would think to So the one that 185 00:11:11,080 --> 00:11:14,840 Speaker 1: Erdman found was brown, right, Yeah, it was a little 186 00:11:14,880 --> 00:11:19,800 Speaker 1: bit different color, right, the one like uh Courtney Lattimer described, 187 00:11:19,960 --> 00:11:22,320 Speaker 1: those are known to be like steel blue. This is 188 00:11:22,320 --> 00:11:25,640 Speaker 1: a brown a little smaller than the one that Courtney 189 00:11:25,720 --> 00:11:30,200 Speaker 1: Lattimer found. Um. And so eventually when Erdman got his 190 00:11:30,240 --> 00:11:34,000 Speaker 1: hands on that one, um, he described it as a 191 00:11:34,000 --> 00:11:38,640 Speaker 1: new species. Yeah. I mean, uh, it turns out that 192 00:11:38,679 --> 00:11:41,240 Speaker 1: at one point, um, you know, hundreds of millions of 193 00:11:41,320 --> 00:11:44,120 Speaker 1: years ago, there were you know, potentially over a hundred 194 00:11:44,160 --> 00:11:47,040 Speaker 1: different varieties of this fish. Uh, and they came in 195 00:11:47,080 --> 00:11:50,760 Speaker 1: all shapes and sizes. Um. These obviously were pretty big, 196 00:11:50,800 --> 00:11:55,160 Speaker 1: but there were some that were smaller and faster. Uh. 197 00:11:55,720 --> 00:11:58,880 Speaker 1: Basically just kind of a wide variety. And as far 198 00:11:58,960 --> 00:12:01,040 Speaker 1: as we know, I think are the the only two 199 00:12:01,679 --> 00:12:07,160 Speaker 1: known survivors, yes, so far. Yeah, the one that Corney 200 00:12:07,240 --> 00:12:11,160 Speaker 1: Latimer founder known as the West Indian Ocean Seila Cant. 201 00:12:11,240 --> 00:12:14,679 Speaker 1: Those are the blue ones, and they're typically found off 202 00:12:14,720 --> 00:12:18,200 Speaker 1: of the west, you know, the east coast of Africa, 203 00:12:18,640 --> 00:12:23,160 Speaker 1: south of Kenya. I believe, um, down to about the 204 00:12:23,200 --> 00:12:27,360 Speaker 1: Cormoros Islands. I think that's they're actually also known as 205 00:12:27,400 --> 00:12:31,320 Speaker 1: the Cormoros Islands Celia Cant because there's that's that seems 206 00:12:31,360 --> 00:12:34,200 Speaker 1: to be where they inhabit the most or the highest 207 00:12:34,200 --> 00:12:36,960 Speaker 1: density of them is Yeah, and UM, some of the 208 00:12:37,000 --> 00:12:41,440 Speaker 1: weird some of the weirdos that have well, we assumed 209 00:12:41,480 --> 00:12:44,280 Speaker 1: that they've been extinct, but you never know. One of 210 00:12:44,320 --> 00:12:48,040 Speaker 1: them was toothless, uh and over ten feet long. That 211 00:12:48,160 --> 00:12:52,120 Speaker 1: was the megalo se La canthus very appropriately, Uh, some 212 00:12:52,200 --> 00:12:54,920 Speaker 1: of them said forget you, ocean, I'm gonna go to 213 00:12:54,960 --> 00:12:58,080 Speaker 1: the freshwater. So they were actually freshwater Cela cants at 214 00:12:58,080 --> 00:13:00,600 Speaker 1: one time. And like I said, some of them were 215 00:13:00,760 --> 00:13:06,440 Speaker 1: slow and ambushed prey somewhere uh, smaller and faster. But 216 00:13:06,520 --> 00:13:10,600 Speaker 1: they've pretty much universally all been predators from what I've seen, 217 00:13:11,400 --> 00:13:14,640 Speaker 1: and the two species that are alive today that we 218 00:13:14,720 --> 00:13:18,960 Speaker 1: know of UM are aside from that Megalis Cela cant 219 00:13:19,440 --> 00:13:21,400 Speaker 1: um tend to be a little bigger than the the 220 00:13:21,480 --> 00:13:27,600 Speaker 1: extinct species, which UM I read is a good it's 221 00:13:27,600 --> 00:13:30,480 Speaker 1: a good example of why they shouldn't be called living fossils, 222 00:13:30,480 --> 00:13:34,000 Speaker 1: which is what they're frequently called. Yeah, that's Darwin's term 223 00:13:34,080 --> 00:13:39,080 Speaker 1: for something that UM basically never changed. Uh. And they've 224 00:13:39,120 --> 00:13:42,760 Speaker 1: actually studied the genome of the Cela cant and found 225 00:13:43,120 --> 00:13:46,599 Speaker 1: that they very much haven't changed and the kind of 226 00:13:46,679 --> 00:13:49,640 Speaker 1: the main reason is they haven't had to. Um, they've 227 00:13:49,720 --> 00:13:52,840 Speaker 1: kind of stayed in the same places. And when you 228 00:13:52,880 --> 00:13:55,240 Speaker 1: stay in the same places and you eat the same stuff, 229 00:13:55,760 --> 00:13:58,120 Speaker 1: then maybe you don't change so much. I read the 230 00:13:58,400 --> 00:14:01,000 Speaker 1: I read the opposite of that, they have changed enough 231 00:14:01,040 --> 00:14:04,040 Speaker 1: that they that they have been evolving in a good 232 00:14:04,080 --> 00:14:06,320 Speaker 1: example of that is that they're bigger than they used 233 00:14:06,360 --> 00:14:09,800 Speaker 1: to be. Interesting. Yeah, but the two species that are 234 00:14:09,800 --> 00:14:14,080 Speaker 1: alive today, Um, they have traced their genomes back and 235 00:14:14,160 --> 00:14:18,560 Speaker 1: decided that they've been separated for several million years at least. Yeah, 236 00:14:18,559 --> 00:14:21,680 Speaker 1: this one. Uh, they finally got the full genome and 237 00:14:21,720 --> 00:14:25,320 Speaker 1: they said that, uh, it does indeed match the fish's 238 00:14:25,320 --> 00:14:28,920 Speaker 1: appearance of slower evolution and a journal published in Nature 239 00:14:29,600 --> 00:14:33,840 Speaker 1: because they have a slower rate of substitution. Um. Basically, 240 00:14:34,080 --> 00:14:38,760 Speaker 1: she the doctor, well, yeah, I guess she has a doctor. 241 00:14:39,240 --> 00:14:42,080 Speaker 1: Just sounded weird to say that. The doctor the researcher 242 00:14:42,120 --> 00:14:44,680 Speaker 1: who was also a doctor, who was she said it 243 00:14:44,720 --> 00:14:46,360 Speaker 1: may reflect the fact that they do not need to 244 00:14:46,400 --> 00:14:50,560 Speaker 1: evolve quickly because they've lived in relatively unchanging environment whe 245 00:14:50,560 --> 00:14:54,480 Speaker 1: there are a few predators. Uh, and they basically haven't 246 00:14:54,520 --> 00:14:57,040 Speaker 1: needed to change over time like other organisms. Well, that 247 00:14:57,040 --> 00:14:59,720 Speaker 1: brings up another thing too, there's a there's a big 248 00:15:00,360 --> 00:15:02,760 Speaker 1: why would they just drop off of the fossil record 249 00:15:02,800 --> 00:15:05,480 Speaker 1: if they've been around this whole time, if they didn't 250 00:15:05,520 --> 00:15:08,360 Speaker 1: just go extinct eighty or sixty five million years ago. 251 00:15:08,760 --> 00:15:12,280 Speaker 1: The um only explanation I've seen is that the places 252 00:15:12,280 --> 00:15:16,280 Speaker 1: where the fossils turned up where areas conducive to fossilization, 253 00:15:16,400 --> 00:15:18,000 Speaker 1: Like there was a lot of sentiment that could turn 254 00:15:18,120 --> 00:15:21,480 Speaker 1: bone into rock. And then the areas that the living 255 00:15:21,960 --> 00:15:25,200 Speaker 1: uh species live at now are not conducive to that 256 00:15:25,320 --> 00:15:29,040 Speaker 1: kind of thing, possibly because they're mostly living around volcanic 257 00:15:29,120 --> 00:15:33,520 Speaker 1: rock that doesn't necessarily produce fossils. You want to take 258 00:15:33,560 --> 00:15:35,280 Speaker 1: a break, Yeah, let's take a break and we'll get 259 00:15:35,280 --> 00:15:59,880 Speaker 1: back and talk a little bit about this funny fish. 260 00:16:00,480 --> 00:16:02,360 Speaker 1: All right, So we talked a little bit about what 261 00:16:02,520 --> 00:16:07,040 Speaker 1: makes the Celo camp such a interesting critter. Um. Can 262 00:16:07,080 --> 00:16:09,840 Speaker 1: a critter be a fish? Yeah? Have you heard of 263 00:16:09,840 --> 00:16:12,000 Speaker 1: the cuttle fish? That's a critter? If there ever was 264 00:16:12,840 --> 00:16:16,400 Speaker 1: a cuddly critter. Uh So, here are some remarkable things 265 00:16:16,440 --> 00:16:20,880 Speaker 1: about the Cela camp um. They can live as deep 266 00:16:20,920 --> 00:16:22,840 Speaker 1: I mean, they're deep water dwellers. They can live as 267 00:16:22,880 --> 00:16:26,960 Speaker 1: deep as two thousand or more feet, but generally, uh, 268 00:16:27,000 --> 00:16:32,280 Speaker 1: they think the UM I think they generally live about 269 00:16:32,320 --> 00:16:35,560 Speaker 1: five eight hundred feet and what they call the twilight zone, 270 00:16:35,880 --> 00:16:39,720 Speaker 1: which is still pretty deep. That Remember our cave episode, Yeah, 271 00:16:39,960 --> 00:16:42,400 Speaker 1: UM that had the same thing. Remember there was like 272 00:16:42,920 --> 00:16:45,880 Speaker 1: organisms that live in the dark, organisms that live in 273 00:16:45,880 --> 00:16:48,800 Speaker 1: the twilight zone, and organisms that live in the lighted zone. Yeah, 274 00:16:48,840 --> 00:16:51,160 Speaker 1: these guys live in that threshold between light and dark 275 00:16:51,200 --> 00:16:56,560 Speaker 1: in the ocean. And they um apparently are nocturnal hunters. Yeah, 276 00:16:56,600 --> 00:16:59,600 Speaker 1: they come out at night, Uh, kind of stay hidden. 277 00:17:00,840 --> 00:17:05,320 Speaker 1: Most of these habitats are are caves, right that they 278 00:17:05,320 --> 00:17:07,879 Speaker 1: tend to stay in. But there's one off of Tasmania 279 00:17:08,080 --> 00:17:10,199 Speaker 1: that do not live in caves, and so they have 280 00:17:10,320 --> 00:17:13,440 Speaker 1: officially been placed on an endangered list because they don't 281 00:17:13,440 --> 00:17:18,320 Speaker 1: have the protection from bycatch that these other cave dwellers have. 282 00:17:20,160 --> 00:17:24,600 Speaker 1: That makes sense, Yeah, so they the average day in 283 00:17:24,680 --> 00:17:26,960 Speaker 1: the life of a cila can't at least the cave 284 00:17:27,040 --> 00:17:31,520 Speaker 1: dwelling UM species. They they'll you know, the during the daytime, 285 00:17:31,560 --> 00:17:33,240 Speaker 1: they're hanging out in a cave. They'll hang out in 286 00:17:33,280 --> 00:17:37,000 Speaker 1: a cave with I've seen between up the twelve to sixteen. 287 00:17:37,040 --> 00:17:41,600 Speaker 1: Other Ceila cants have coffee. Yeah, maybe just talk, you know, 288 00:17:41,720 --> 00:17:45,560 Speaker 1: talk about their night and then as nightfalls, they'll leave 289 00:17:45,600 --> 00:17:48,359 Speaker 1: their caves and they'll they'll go hunting. And like you said, 290 00:17:48,400 --> 00:17:53,240 Speaker 1: their um carnivorous predators. Um, they do that passive by 291 00:17:53,320 --> 00:17:56,240 Speaker 1: catch thing for the most part right where they let 292 00:17:56,240 --> 00:18:02,240 Speaker 1: the the current bring the food to them. But they 293 00:18:02,400 --> 00:18:05,760 Speaker 1: just basically hang out and wait for a cuttle fish. 294 00:18:05,800 --> 00:18:10,920 Speaker 1: It's one thing. They eat squids, other cephalopods, some fishes, 295 00:18:11,359 --> 00:18:14,520 Speaker 1: but they seem to not um show aggression towards one 296 00:18:14,520 --> 00:18:18,320 Speaker 1: another from what I understand. Yeah, and um, while they 297 00:18:18,320 --> 00:18:21,679 Speaker 1: are passive hunters, they do have an unusual feature which is, 298 00:18:22,720 --> 00:18:24,400 Speaker 1: like we said, one of many. But they have what's 299 00:18:24,400 --> 00:18:27,240 Speaker 1: called a rostral organ, which just means it's in the 300 00:18:27,320 --> 00:18:30,879 Speaker 1: nasal region and their snout uh, and it's filled with 301 00:18:30,920 --> 00:18:35,720 Speaker 1: a jellylike substance that they think uh. And they think 302 00:18:35,800 --> 00:18:37,239 Speaker 1: most of this stuff. I mean, they've done a lot 303 00:18:37,240 --> 00:18:39,840 Speaker 1: of good studying, but for something so rare, you can't 304 00:18:40,000 --> 00:18:42,119 Speaker 1: you know, be super sure. But they think that it 305 00:18:42,160 --> 00:18:48,280 Speaker 1: detects low level electrical signals and frequencies from prey. Yeah, 306 00:18:48,320 --> 00:18:51,600 Speaker 1: like a shark or array. Yeah, it's an electrosensory organ 307 00:18:51,680 --> 00:18:55,320 Speaker 1: where when living tissue contacts water, it can make an 308 00:18:55,320 --> 00:18:58,159 Speaker 1: electrical impulse that can be picked up. Yeah, and this 309 00:18:58,400 --> 00:19:03,359 Speaker 1: cool mental floss articles at eleven um eleven things about 310 00:19:03,400 --> 00:19:06,119 Speaker 1: the sea. Look ant, I can't remember how it was put, 311 00:19:06,480 --> 00:19:13,200 Speaker 1: but just eleven interesting features, eleven fishy facts. Unfortunately that's 312 00:19:13,200 --> 00:19:16,879 Speaker 1: why I forgot it, uh title aside, it's an interesting article. 313 00:19:17,040 --> 00:19:20,600 Speaker 1: And um. One of the things that they don't know 314 00:19:20,600 --> 00:19:21,919 Speaker 1: why they do, and I have a feeling it has 315 00:19:21,960 --> 00:19:24,760 Speaker 1: to do with that electrical frequency, is they will swim 316 00:19:24,840 --> 00:19:28,680 Speaker 1: nose down, um for up to two full minutes, which 317 00:19:28,720 --> 00:19:31,280 Speaker 1: is weird for a fish. It just kind of hovering 318 00:19:31,320 --> 00:19:35,560 Speaker 1: in place, headstanding, right, Yeah, and I guess I mean 319 00:19:35,840 --> 00:19:39,959 Speaker 1: if they have that nasal uh bag of a jelly 320 00:19:40,440 --> 00:19:42,399 Speaker 1: that helps them locate fish, I would imagine that's what 321 00:19:42,520 --> 00:19:45,639 Speaker 1: they're doing there, right. I imagine it like tonto, like 322 00:19:45,760 --> 00:19:49,960 Speaker 1: holding a railroad track, you know. Yeah, I think it's 323 00:19:49,960 --> 00:19:55,560 Speaker 1: the same thing basically. So um, when they catch their prey, 324 00:19:55,720 --> 00:19:58,440 Speaker 1: they eat them, and they can eat stuff that's way 325 00:19:58,440 --> 00:20:02,280 Speaker 1: bigger than them because I again, which is this is 326 00:20:02,400 --> 00:20:06,280 Speaker 1: um unique to see the cants among living things They 327 00:20:06,320 --> 00:20:09,960 Speaker 1: have a hinge in their cranium that allows basically their 328 00:20:09,960 --> 00:20:13,000 Speaker 1: head is convertible. The top of their skull can retract, 329 00:20:13,320 --> 00:20:16,560 Speaker 1: allowing their mouth to open really wide, so they can 330 00:20:16,600 --> 00:20:20,280 Speaker 1: eat a large, large cuttle fish. Yeah. And I think 331 00:20:20,320 --> 00:20:24,000 Speaker 1: the that feature also allows it to uh, their mouth 332 00:20:24,040 --> 00:20:28,200 Speaker 1: to close with like much greater force with extreme prejudice. Yeah, 333 00:20:28,240 --> 00:20:33,960 Speaker 1: like when it's unhinged um emotionally and physically, it can 334 00:20:34,000 --> 00:20:37,760 Speaker 1: really close that mouth, uh, super hard. They hate themselves 335 00:20:37,760 --> 00:20:41,680 Speaker 1: for eating cuttle so I just can't stop. So those 336 00:20:41,720 --> 00:20:44,960 Speaker 1: are just a couple of the features. Another is um 337 00:20:45,000 --> 00:20:48,600 Speaker 1: and we mentioned earlier that the name literally translates into 338 00:20:48,760 --> 00:20:52,040 Speaker 1: hollow spine. Uh. This is because they have what's called 339 00:20:52,040 --> 00:20:56,639 Speaker 1: a noo chord, which is a hollow pressurized tube filled 340 00:20:56,640 --> 00:21:01,719 Speaker 1: with oil where a lot of fish start this way 341 00:21:02,040 --> 00:21:04,399 Speaker 1: and then they'll eventually get a spine. But this doesn't 342 00:21:04,400 --> 00:21:07,639 Speaker 1: go away, right, And not just fish vertebrates apparently, um, 343 00:21:07,680 --> 00:21:09,600 Speaker 1: there's a lot of mammals that go through this, I 344 00:21:09,640 --> 00:21:13,560 Speaker 1: think possibly even humans. In the embryo and the sela 345 00:21:13,600 --> 00:21:15,680 Speaker 1: cancer says, I'm good with the noto coorse, I'm gonna 346 00:21:15,720 --> 00:21:18,679 Speaker 1: stick here, I'm gonna stop here, which is strange. It 347 00:21:18,840 --> 00:21:20,879 Speaker 1: is strange. You want to hear some more stranges. I 348 00:21:20,880 --> 00:21:23,440 Speaker 1: could do this all day. Well, it's a strange fish. 349 00:21:23,600 --> 00:21:28,840 Speaker 1: Cela canth um. We don't quite understand how they reproduce, 350 00:21:29,200 --> 00:21:34,080 Speaker 1: and the reason why is because males don't seem to 351 00:21:34,119 --> 00:21:38,400 Speaker 1: have any sex parts. They don't have junk. They think 352 00:21:38,480 --> 00:21:43,440 Speaker 1: possibly males grow it when they need it, but it's otherwise, 353 00:21:43,480 --> 00:21:47,560 Speaker 1: it's it's not around to growers. They're not showers right exctly, 354 00:21:47,760 --> 00:21:51,679 Speaker 1: that's exactly right. So we have no idea how they reproduce, 355 00:21:52,040 --> 00:21:55,240 Speaker 1: but we know that the um the mode of reproduction 356 00:21:55,359 --> 00:22:01,159 Speaker 1: is called uh ovo viviparity, which is how for the 357 00:22:01,200 --> 00:22:04,960 Speaker 1: eggs that the female has get fertilized. Once they're fertilized, 358 00:22:05,320 --> 00:22:09,520 Speaker 1: they just state or the eggs developed in the female, 359 00:22:10,040 --> 00:22:15,119 Speaker 1: and then they hatch in the female, and then the 360 00:22:15,160 --> 00:22:18,879 Speaker 1: live fishes continue to just date. Oh and like the 361 00:22:18,920 --> 00:22:22,840 Speaker 1: whole period last like three years before they're born. So 362 00:22:22,920 --> 00:22:26,879 Speaker 1: they go from egg to being hatched to being born 363 00:22:27,359 --> 00:22:31,760 Speaker 1: within a three year period. And so apparently this does 364 00:22:31,800 --> 00:22:35,280 Speaker 1: not make the mom Cela can't very happy, and sometimes 365 00:22:35,320 --> 00:22:39,280 Speaker 1: she will try to eat her newborn pups. So supposedly 366 00:22:40,200 --> 00:22:44,000 Speaker 1: Cela can't pups, that's what they're called. Can dive really deep, 367 00:22:44,200 --> 00:22:46,640 Speaker 1: very quickly the moment they're born to get away from mom, 368 00:22:46,680 --> 00:22:49,879 Speaker 1: to get away from their mom, who's like three years 369 00:22:50,640 --> 00:22:56,000 Speaker 1: three years paging Dr Freud. Yeah, uh yeah, I think 370 00:22:56,040 --> 00:23:00,280 Speaker 1: sharks maybe the only other uh fish that give the 371 00:23:00,359 --> 00:23:06,119 Speaker 1: live little ones? Is that right? I mean most fish 372 00:23:06,359 --> 00:23:09,840 Speaker 1: lay eggs, right, so that it's definitely unusual. Yeah, it's 373 00:23:10,000 --> 00:23:14,080 Speaker 1: it may not be new unique. Um. But the other 374 00:23:14,119 --> 00:23:16,639 Speaker 1: thing about their their sexy time is there's also a 375 00:23:16,720 --> 00:23:25,200 Speaker 1: theory that, um, they are monogamousts. In a German team. Um, 376 00:23:25,240 --> 00:23:29,000 Speaker 1: they had a couple of corpses of too pregnant. Um. 377 00:23:29,080 --> 00:23:33,320 Speaker 1: I believe that the African version, yeah, the Ladimir chlumni 378 00:23:34,119 --> 00:23:36,760 Speaker 1: and uh because what was I remember the other one? 379 00:23:36,880 --> 00:23:41,400 Speaker 1: It was Ladimir something else. For the Indonesian version, we'll 380 00:23:41,440 --> 00:23:44,760 Speaker 1: just go with that for now. I was practicing pronouncing 381 00:23:44,800 --> 00:23:50,720 Speaker 1: it Latimer menadoensis. Okay, wow, thanks. Uh. So they analyze 382 00:23:50,720 --> 00:23:53,960 Speaker 1: these two pregnant ladies, unfortunately that we're no longer with us, 383 00:23:54,480 --> 00:23:58,160 Speaker 1: and they found out that they had like most definitely 384 00:23:58,240 --> 00:24:02,560 Speaker 1: had a single father, which they said was unusual because 385 00:24:02,600 --> 00:24:07,240 Speaker 1: one of them had twenty six little baby pups inside 386 00:24:07,280 --> 00:24:10,760 Speaker 1: of her, right, and they um, they thought at first, well, 387 00:24:11,000 --> 00:24:15,000 Speaker 1: maybe it's because the Cela cant is so rare that 388 00:24:15,040 --> 00:24:17,920 Speaker 1: the female wouldn't have opportunity to mate with more than 389 00:24:17,960 --> 00:24:20,760 Speaker 1: one male. And they said, well wait a minute, well no, 390 00:24:20,920 --> 00:24:23,200 Speaker 1: not necessarily, once they found out that they stayed to 391 00:24:23,280 --> 00:24:25,760 Speaker 1: hang out together. Yeah, in caves all day long. What 392 00:24:25,800 --> 00:24:29,919 Speaker 1: else are you gonna do? Once general hospitals over just 393 00:24:29,960 --> 00:24:32,160 Speaker 1: looking around and everybody like, whoa, what do you want 394 00:24:32,160 --> 00:24:35,119 Speaker 1: to do? Yeah, that's a good point. All right, Well 395 00:24:35,200 --> 00:24:39,080 Speaker 1: let's uh ponder that and take another break, and uh 396 00:24:39,080 --> 00:24:42,200 Speaker 1: we'll finish up with even more interesting things about the 397 00:24:42,240 --> 00:25:07,879 Speaker 1: ceila cant. Yeah, alright, so these guys have live babies. 398 00:25:08,880 --> 00:25:12,520 Speaker 1: They might mate with a single mate. Good day. They 399 00:25:12,560 --> 00:25:16,720 Speaker 1: have they can unhinge their jaw to eat more. They 400 00:25:16,760 --> 00:25:22,359 Speaker 1: have a jelly filled thing in there, nostra that the 401 00:25:22,760 --> 00:25:27,080 Speaker 1: that the texts electricity, The texts electricity. I know I'm 402 00:25:27,119 --> 00:25:31,200 Speaker 1: having trouble thing to text. Uh what else? This is 403 00:25:31,240 --> 00:25:34,720 Speaker 1: sort of a recap. They have oil filled spine, oil 404 00:25:34,720 --> 00:25:37,080 Speaker 1: filled spine, and they're they're just good with They're like, 405 00:25:37,160 --> 00:25:39,320 Speaker 1: I don't need a real spine. This one is my favorite. 406 00:25:39,840 --> 00:25:44,040 Speaker 1: They were long thought to be the missing link between 407 00:25:44,760 --> 00:25:50,800 Speaker 1: fishes and the tetrapods, which are land dwelling four limbed animals. Yeah, 408 00:25:50,840 --> 00:25:53,240 Speaker 1: because a notable thing I don't think we mentioned yet 409 00:25:53,280 --> 00:25:55,240 Speaker 1: is this thing has well, I think I didn't a 410 00:25:55,320 --> 00:25:59,960 Speaker 1: quote from miss Ladimir Courtney Ladimir, but they have four 411 00:26:00,000 --> 00:26:04,600 Speaker 1: are fins that smooth, sort of like you would think 412 00:26:04,720 --> 00:26:07,359 Speaker 1: legs would move if a fish could swim out onto 413 00:26:07,359 --> 00:26:10,520 Speaker 1: the beach. Legs and arms. Remember how Shaggy walked in 414 00:26:10,560 --> 00:26:14,520 Speaker 1: Scooby Doo, Just like that. That's basically how a ceila 415 00:26:14,600 --> 00:26:18,360 Speaker 1: can't swims. And the fact that they're their fins are 416 00:26:18,400 --> 00:26:23,080 Speaker 1: suspiciously arm like in appearance just made people think that 417 00:26:23,200 --> 00:26:27,280 Speaker 1: even more. What's more, their arms, what are called lobes, 418 00:26:27,720 --> 00:26:31,280 Speaker 1: are attached by a bone that is compared to the 419 00:26:31,400 --> 00:26:34,800 Speaker 1: humorous in humans. So a lot of people said, well, 420 00:26:34,800 --> 00:26:36,919 Speaker 1: that's it. It's a missing link. The cela can't is 421 00:26:36,920 --> 00:26:40,400 Speaker 1: a missing link between the fish and the land dwelling 422 00:26:40,600 --> 00:26:45,560 Speaker 1: four limbed animals. And apparently once the genome came around 423 00:26:45,920 --> 00:26:48,680 Speaker 1: and said now a little disappointing, they said, yes, we're 424 00:26:48,680 --> 00:26:52,680 Speaker 1: all related. Technically, we are all um what are known 425 00:26:52,920 --> 00:27:02,040 Speaker 1: as sarcopterygians okay um, which means we are fleshy limb vertebrates. 426 00:27:02,359 --> 00:27:05,640 Speaker 1: So we're all that. So we are related, but it's 427 00:27:05,680 --> 00:27:08,760 Speaker 1: not like our direct ancestor. In fact, we're more closely 428 00:27:08,800 --> 00:27:12,280 Speaker 1: related to the lungfish than the seila can'ts. But the 429 00:27:12,280 --> 00:27:15,640 Speaker 1: seila can'ts holds this place of honors, probably living on 430 00:27:15,720 --> 00:27:18,920 Speaker 1: something of its own branch uh and is a very 431 00:27:19,000 --> 00:27:22,720 Speaker 1: close cousin, if not bro, of the lung fish. So 432 00:27:22,800 --> 00:27:27,639 Speaker 1: we're related by marriage right to the seal It can't say, 433 00:27:27,680 --> 00:27:30,320 Speaker 1: but we legally we probably could marry a sela can't 434 00:27:31,000 --> 00:27:33,919 Speaker 1: and have it not be super creepy except for the 435 00:27:33,920 --> 00:27:37,520 Speaker 1: thet it's a fish. I feel it's a fleshy, lobed 436 00:27:37,560 --> 00:27:40,520 Speaker 1: thin stroking the back of your head as you kiss it. 437 00:27:41,280 --> 00:27:44,240 Speaker 1: I got something for you that was I'm just walking 438 00:27:44,320 --> 00:27:48,400 Speaker 1: right past that one. Um. They taste gross, so don't 439 00:27:48,440 --> 00:27:52,479 Speaker 1: think it's some weird delicacy, right, uh not? You know 440 00:27:52,520 --> 00:27:54,600 Speaker 1: that there are that many of them to eat, But 441 00:27:54,760 --> 00:27:56,879 Speaker 1: apparently if you do eat them, they can make you 442 00:27:56,920 --> 00:28:02,439 Speaker 1: sick because these things are filled with urea, with oil, 443 00:28:03,000 --> 00:28:08,720 Speaker 1: with wax, esther and fat like ninety eight point five 444 00:28:08,720 --> 00:28:11,880 Speaker 1: percent fat. That's just in its skull. Oh I thought 445 00:28:11,880 --> 00:28:15,640 Speaker 1: that was the whole body. No, it's it's brain occupies 446 00:28:15,760 --> 00:28:21,320 Speaker 1: one point five of the area inside its skull. The 447 00:28:21,359 --> 00:28:25,240 Speaker 1: other is fat. And that's at the point that they're 448 00:28:25,280 --> 00:28:29,160 Speaker 1: an adult, right. Yeah. Supposedly their brains are bigger proportionately 449 00:28:29,200 --> 00:28:32,760 Speaker 1: when they're younger, and they just stay there. Yeah, they're 450 00:28:32,760 --> 00:28:38,480 Speaker 1: frozen in uh, perpetual like I guess toddler hood pretty much. 451 00:28:38,760 --> 00:28:47,720 Speaker 1: They love life. Yeah, no responsibilities, no bills, exactly. What 452 00:28:47,800 --> 00:28:54,760 Speaker 1: else I got one for you? Okay. Vestigial lungs Oh yeah, man, 453 00:28:54,840 --> 00:28:59,000 Speaker 1: I love these things. So they grow, They had CT 454 00:28:59,120 --> 00:29:01,280 Speaker 1: scans done and this is from the mental flass article 455 00:29:02,400 --> 00:29:07,080 Speaker 1: of these embryos, and they start growing little lungs uh 456 00:29:07,200 --> 00:29:12,920 Speaker 1: early in the gestation period and it slows down a bit, 457 00:29:13,080 --> 00:29:15,520 Speaker 1: and then by the time they're an adult, the organ 458 00:29:15,760 --> 00:29:21,120 Speaker 1: serves no purpose. Yeah, it's just there. Yep, that's a 459 00:29:21,160 --> 00:29:24,080 Speaker 1: good one. It is. It was. It's almost like the 460 00:29:24,080 --> 00:29:29,040 Speaker 1: Cela canth was an attempt and evolutionary attempt, and it's 461 00:29:29,080 --> 00:29:32,080 Speaker 1: just like, I'm gonna scrap this design. Let's move on 462 00:29:32,160 --> 00:29:36,920 Speaker 1: to the long fish. Yeah maybe so you know, um, 463 00:29:37,080 --> 00:29:38,840 Speaker 1: one of the things that struck me though, Chuck, was 464 00:29:38,880 --> 00:29:41,280 Speaker 1: when they were talking about how a couple of females 465 00:29:41,600 --> 00:29:45,120 Speaker 1: that had fully formed young yeah in them, ready to 466 00:29:45,160 --> 00:29:49,000 Speaker 1: be born, were caught. It's like that was a lot 467 00:29:49,320 --> 00:29:51,800 Speaker 1: of the Cela canth population that got wiped out with 468 00:29:51,840 --> 00:29:54,239 Speaker 1: those two caught fish. Yeah. I mean, if there are 469 00:29:54,240 --> 00:29:59,000 Speaker 1: only hundreds, then everyone matters. Yeah. They think that there's 470 00:29:59,000 --> 00:30:02,320 Speaker 1: possibly about a th thousand of the ones that live 471 00:30:02,360 --> 00:30:07,960 Speaker 1: around Indonesia and far fewer of the ones that live 472 00:30:08,720 --> 00:30:11,680 Speaker 1: off of the west coast of Africa on the western 473 00:30:11,720 --> 00:30:15,520 Speaker 1: side of the Indian Ocean. Um. And as a result, 474 00:30:15,600 --> 00:30:18,400 Speaker 1: both of them are on the Endangered Species list. They're 475 00:30:18,440 --> 00:30:22,360 Speaker 1: both protected. The problem is that if something happens to 476 00:30:23,080 --> 00:30:26,000 Speaker 1: these species and these species die out this time, the 477 00:30:26,080 --> 00:30:31,600 Speaker 1: whole order is gone, um for good this time around. Yeah, 478 00:30:31,840 --> 00:30:36,600 Speaker 1: unless we revive them, uh with some of their DNA. Alright, 479 00:30:36,640 --> 00:30:40,160 Speaker 1: I got one last one um And this was on 480 00:30:40,240 --> 00:30:44,960 Speaker 1: Mental Flosses list as well, under the title A prominent 481 00:30:45,000 --> 00:30:50,040 Speaker 1: hematologist once wrote a celacanth operetta A right, So that's 482 00:30:50,040 --> 00:30:54,640 Speaker 1: an attention grabber. Apparently there was a man named Charles 483 00:30:54,760 --> 00:30:59,800 Speaker 1: Rand of Long Guideland University, and he was a hematologist, 484 00:31:00,040 --> 00:31:02,960 Speaker 1: and um was doing some work with the Cela Camp 485 00:31:03,720 --> 00:31:06,800 Speaker 1: and uh, this is when the big revelation was. They 486 00:31:06,880 --> 00:31:09,360 Speaker 1: learned that it gave birth to live young. And he, 487 00:31:09,600 --> 00:31:14,440 Speaker 1: I guess, was a music guy and decided to write 488 00:31:15,120 --> 00:31:19,400 Speaker 1: a little operetta about this discovery titled a Cila Camp's 489 00:31:19,600 --> 00:31:24,000 Speaker 1: Lament or Quinn Tuplets at fifty fathoms can be fun 490 00:31:25,080 --> 00:31:30,640 Speaker 1: all song to the tune of various Gilbert and Sullivan songs.

But there's there's some 499 00:32:03,200 --> 00:32:07,080 Speaker 1: interesting fishes that are worth mentioning. Speaking of making the jump, 500 00:32:07,120 --> 00:32:09,160 Speaker 1: did you see that shark that jumped into the boat 501 00:32:09,200 --> 00:32:12,400 Speaker 1: the other day? There was a fisherman, Uh, and I 502 00:32:12,400 --> 00:32:14,160 Speaker 1: guess the shark just did you know one of their 503 00:32:14,200 --> 00:32:17,200 Speaker 1: famous uh it was a great white did one of 504 00:32:17,200 --> 00:32:20,160 Speaker 1: its breeches where they just jump out of the water. 505 00:32:20,640 --> 00:32:24,120 Speaker 1: Missing did that and landed in a dude's fishing boat. Uh. 506 00:32:24,160 --> 00:32:26,520 Speaker 1: And he got banged around a little bit but was 507 00:32:26,560 --> 00:32:29,840 Speaker 1: not like, you know, a bitten or anything, and basically 508 00:32:29,840 --> 00:32:31,840 Speaker 1: went into his little control room I think, and called 509 00:32:31,840 --> 00:32:34,600 Speaker 1: for help. And this shark like, I mean, it was 510 00:32:34,640 --> 00:32:37,440 Speaker 1: kind of sad. I think the shark just died. But 511 00:32:37,600 --> 00:32:39,720 Speaker 1: there were pictures of it. It's it's huge, it's like 512 00:32:39,720 --> 00:32:42,440 Speaker 1: eight ft long. It was not a little guy. Yeah, 513 00:32:42,560 --> 00:32:45,440 Speaker 1: do you imagine? No, Oh my god, that guy did 514 00:32:45,480 --> 00:32:48,760 Speaker 1: the right thing. He ran. He pooped his pants too. Yeah. 515 00:32:49,120 --> 00:32:52,960 Speaker 1: I may have jumped into the water had that happened. Alright. 516 00:32:53,040 --> 00:32:58,280 Speaker 1: So living fossils um, the bow fin, yeah, the dog fish, 517 00:32:58,400 --> 00:33:04,400 Speaker 1: mudfish or grindel I like dog fish. Yeah, this guy, 518 00:33:04,480 --> 00:33:06,320 Speaker 1: I looked all these up, lily. He lives in the 519 00:33:06,320 --> 00:33:10,800 Speaker 1: Mississippi River basin, in the Great Lakes and other places. Um, 520 00:33:10,880 --> 00:33:16,280 Speaker 1: and are pretty mean supposedly like eats small mammals, snakes, frogs, 521 00:33:16,360 --> 00:33:20,240 Speaker 1: other fish like they'll they'll go after you. Um. It's 522 00:33:20,280 --> 00:33:24,080 Speaker 1: sort of normal looking, just sort of a long fish. Uh. 523 00:33:24,360 --> 00:33:27,680 Speaker 1: Nothing remarkable as appearance wise, though, I'll tell you one 524 00:33:27,720 --> 00:33:31,080 Speaker 1: that's remarkable appearance wises. The gar. Yeah, you know, I 525 00:33:31,280 --> 00:33:36,000 Speaker 1: just saw a long nosegar so ugly last weekend and 526 00:33:36,040 --> 00:33:38,680 Speaker 1: I was like, it was floating dead in a lake. 527 00:33:39,320 --> 00:33:42,880 Speaker 1: I was like, what in the world. Because I went 528 00:33:42,920 --> 00:33:45,640 Speaker 1: by it at first, I was like, was that a swordfish? Like, well, no, 529 00:33:45,760 --> 00:33:48,400 Speaker 1: it's not a swordfish. But in the long nose ones, 530 00:33:48,440 --> 00:33:50,840 Speaker 1: I mean this this thing had a he had a 531 00:33:50,840 --> 00:33:55,320 Speaker 1: twelve inch beak. I mean it looks prehistoric. Yeah, they 532 00:33:55,440 --> 00:33:57,200 Speaker 1: very much do look prehistoric, which is one of the 533 00:33:57,240 --> 00:34:00,400 Speaker 1: reasons why they're called a living fossil um. And they 534 00:34:00,400 --> 00:34:04,040 Speaker 1: are just mean. Apparently they're known to kill other fish, 535 00:34:04,840 --> 00:34:07,800 Speaker 1: even not even to eat them, just because they were 536 00:34:07,800 --> 00:34:10,640 Speaker 1: in their way. Basically, like you see this nose. Yeah, 537 00:34:10,719 --> 00:34:13,239 Speaker 1: and you can't eat gar. They're inedible and as a 538 00:34:13,280 --> 00:34:15,200 Speaker 1: matter of fact, if you eat their eggs, it will 539 00:34:15,280 --> 00:34:18,040 Speaker 1: kill you. They're very toxic to humans and they just 540 00:34:18,080 --> 00:34:21,279 Speaker 1: go around killing other fish, So they're not the best 541 00:34:21,320 --> 00:34:23,000 Speaker 1: thing to have in your like if you like to 542 00:34:23,080 --> 00:34:26,120 Speaker 1: fish in a lake. No, and they did you ever 543 00:34:26,160 --> 00:34:29,319 Speaker 1: see Vernon, Florida the documentary? No, I've never seen that one. 544 00:34:29,360 --> 00:34:31,600 Speaker 1: By the great Errol Morris. It has uh one of 545 00:34:31,600 --> 00:34:35,120 Speaker 1: the interviews, it's one of my favorites, as with a 546 00:34:35,120 --> 00:34:39,160 Speaker 1: guy talking about talking about the garfish. Really, yeah, I 547 00:34:39,160 --> 00:34:41,640 Speaker 1: gotta see that one. Come across one of those. Oh boy, 548 00:34:41,920 --> 00:34:44,480 Speaker 1: I finally saw a thin blue line for the first time. 549 00:34:44,520 --> 00:34:46,600 Speaker 1: Oh yeah, that's a good one. It's really You probably 550 00:34:46,640 --> 00:34:51,879 Speaker 1: saw it after the parody of documentary Now, I definitely did. 551 00:34:51,880 --> 00:34:54,160 Speaker 1: I saw the documentary now on which they nailed like, 552 00:34:54,239 --> 00:34:58,160 Speaker 1: it's like perfect. They really one of the great shows. Uh, 553 00:34:58,200 --> 00:35:01,800 Speaker 1: what's the next? Hagfish? Yeah, mud dwellers. Yeah, they basically 554 00:35:01,800 --> 00:35:05,279 Speaker 1: look like eels, but their fish. But the interesting thing 555 00:35:05,280 --> 00:35:07,319 Speaker 1: about hag fish, aside from the fact that they don't 556 00:35:07,320 --> 00:35:11,279 Speaker 1: have any eyes, is that they eat fish from the 557 00:35:11,360 --> 00:35:14,279 Speaker 1: inside out. Yeah. I think you underplayed it when he 558 00:35:14,320 --> 00:35:16,839 Speaker 1: said they basically look like eels. It looks like something 559 00:35:16,880 --> 00:35:19,879 Speaker 1: out of Dune. Okay, like the body looks like an eel. 560 00:35:19,920 --> 00:35:22,520 Speaker 1: But have you seen the front end of this thing? Sure, 561 00:35:22,800 --> 00:35:26,759 Speaker 1: it's frightening. And to think about that crawling up in 562 00:35:26,760 --> 00:35:29,080 Speaker 1: you and eating you from the inside out, right, because 563 00:35:29,080 --> 00:35:31,799 Speaker 1: if you're dead or dying fish and you're like, oh man, 564 00:35:31,880 --> 00:35:34,440 Speaker 1: I hope, I hurry up and die before a hagfish 565 00:35:34,480 --> 00:35:38,640 Speaker 1: five and a hagfish swims down your throat and then 566 00:35:38,760 --> 00:35:41,719 Speaker 1: eat you from the inside out. That's a bad day. 567 00:35:41,920 --> 00:35:45,800 Speaker 1: That's not a good death. And then lastly, what about 568 00:35:45,800 --> 00:35:48,520 Speaker 1: the sturgeon. I love the sturgeon. Did you know that 569 00:35:48,560 --> 00:35:52,560 Speaker 1: they they are both freshwater and saltwater here in North America? 570 00:35:53,000 --> 00:35:55,839 Speaker 1: I did not know that, But um, I know one 571 00:35:55,880 --> 00:35:58,840 Speaker 1: thing is they're huge. Yeah, they get up to like 572 00:35:58,880 --> 00:36:01,160 Speaker 1: twenty ft long. Yeah, and I didn't I didn't see 573 00:36:01,160 --> 00:36:03,080 Speaker 1: any pictures of him that big, but I've seen pictures 574 00:36:03,080 --> 00:36:06,600 Speaker 1: of fishermen with like sturgeon that looked like they're at 575 00:36:06,640 --> 00:36:10,440 Speaker 1: least eight or nine feet long. Uh. And they're crazy looking. Yeah. Well, 576 00:36:10,480 --> 00:36:13,160 Speaker 1: the reason I was surprised that they are largely North 577 00:36:13,200 --> 00:36:17,480 Speaker 1: America's I always associate them with, um, the Baltic area 578 00:36:17,560 --> 00:36:22,719 Speaker 1: where they they're the beluga sturgeon is prized for its 579 00:36:22,760 --> 00:36:25,440 Speaker 1: caviar I always think of, I think sturgeon. No, I 580 00:36:25,480 --> 00:36:29,080 Speaker 1: didn't realize that that's where bluga came from either. Uh. 581 00:36:29,120 --> 00:36:31,520 Speaker 1: And they have armor like skin, and they're they're these 582 00:36:31,560 --> 00:36:34,840 Speaker 1: retractable mouths that I guess there are different varieties, but 583 00:36:34,880 --> 00:36:37,920 Speaker 1: some of them look almost like alligators from like the 584 00:36:38,000 --> 00:36:41,120 Speaker 1: head forward. Yeah, they're weird looking fish. Yeah, but they 585 00:36:41,120 --> 00:36:42,840 Speaker 1: don't want to hurt anybody. They just want you to 586 00:36:42,840 --> 00:36:46,120 Speaker 1: eat their eggs. Is that true? They're like the giving 587 00:36:46,160 --> 00:36:50,719 Speaker 1: tree of the lake. All right, up with sturgeon? Uh 588 00:36:50,960 --> 00:36:52,960 Speaker 1: you anything else? I got nothing else? But if you 589 00:36:53,000 --> 00:36:56,400 Speaker 1: want to know more about living fossils, like uh, you 590 00:36:56,440 --> 00:37:00,879 Speaker 1: know Cela, cants or us Right, you can type those 591 00:37:00,920 --> 00:37:03,640 Speaker 1: words in the search bar at how stuff works dot com. 592 00:37:03,680 --> 00:37:06,279 Speaker 1: And since I said search farts, time for a listener mail. 593 00:37:08,960 --> 00:37:14,880 Speaker 1: I'm gonna call this My mom married Bob Doro.

And then the very first 596 00:37:21,080 --> 00:37:23,680 Speaker 1: line of the email was sorry about that attention grabbing 597 00:37:23,760 --> 00:37:26,320 Speaker 1: subject line. And I thought it was a lie because 598 00:37:26,320 --> 00:37:28,960 Speaker 1: a lot of times people say something remarkable in the 599 00:37:29,000 --> 00:37:32,480 Speaker 1: subject line that is completely false, which always ticks me off. 600 00:37:33,160 --> 00:37:36,800 Speaker 1: But this is true.

I wanted to jump through my 611 00:38:04,560 --> 00:38:08,160 Speaker 1: phone to say I can make that happen. Bob learned 612 00:38:08,200 --> 00:38:10,719 Speaker 1: about you guys about two weeks ago when we took 613 00:38:10,760 --> 00:38:12,719 Speaker 1: a short road trip for Mother's Day and listen to 614 00:38:12,760 --> 00:38:16,400 Speaker 1: the grave Robbing episode.
