  • Resumen

  • This week we examine two recent articles about coelacanth discoveries. Which one is real and which one is fake?! Further reading: Fake California Coelacanth First record of a living coelacanth from North Maluku, Indonesia A real coelacanth photo: A fake coelacanth photo (or at least the article is a fake) [photo taken from the first article linked above]: A real coelacanth photo [photo from the second article linked above]: Show transcript: Welcome to Strange Animals Podcast. I’m your host, Kate Shaw. I had another episode planned for this week, but then I read an article by geologist Sharon Hill and decided the topic she researched was so important we need to cover it here. No, it’s not the dire wolf—that’s next week. It’s the coelacanth. We talked about the coelocanth way back in episode two, with updates in a few later episodes. Because episode two is so old that it’s dropped off the podcast feed, and to listen to it you have to actually go to the podcast’s website, I’m going to quote from it extensively here. In December of 1938, a museum curator in South Africa named Marjorie Courtenay Lattimer got a message from a friend of hers, a fisherman named Hendrick Goosen, who had just arrived with a new catch. Lattimer was on the lookout for specimens for her tiny museum, and Goosen was happy to let her have anything interesting. Lattimer went down to the dock. Then she noticed THE FISH. It was five feet long, or 1.5 meters, blueish with shimmery silvery markings, with strange lobed fins and scales like armored plates. She described it as the most beautiful fish she had ever seen. She didn’t know what it was, but she wanted it. She took the fish back to the museum in a taxi and went through her reference books to identify it. Imagine it. She’s flipped through a couple of books but nothing looks even remotely like her fish. Then she turns a page and there’s a picture of the fish--but it’s extinct. It’s been extinct for some 66 million years. But it’s also a very recently alive fish resting on ice in the back of her museum. Lattimer sketched the fish and sent the drawing and a description to a professor at Rhodes University, J.L.B. Smith. But Smith was on Christmas break and didn’t get her message until January 3rd. In the meantime, Lattimer’s museum director told her the fish was a grouper and not worth the ice it was lying on. December is the middle of summer in South Africa, so to keep the fish from rotting away, she had it mounted. Then Smith sent her a near-hysterical cable that read, “MOST IMPORTANT PRESERVE SKELETON AND GILLS.” Oops. Smith got a little obsessed about finding another coelacanth. He offered huge rewards for a specimen. But it wasn’t until December of 1952 that a pair of local fishermen on the island of Anjuan, about halfway between Tanzania and Madagascar, turned up with a fish they called the gombessa. It was a second coelacanth. Everyone was happy. The fishermen got a huge reward—a hundred British pounds—and Smith had an intact coelacanth. He actually cried when he saw it. Most people have heard of the coelacanth because its discovery is such a great story. But why is the fish such a big deal? The coelacanth isn’t just a fish that was supposed to be extinct and was discovered alive and well, although that’s pretty awesome. It’s a strange fish, more closely related to mammals and reptiles than it is to ordinary ray-finned fish. The only living fish even slightly like it is the lungfish, which we talked about in episode 55. While the coelacanth is unique in a lot of ways, it’s those lobed fins that are really exciting. It’s not a stretch to say its paired fins look like nubby legs with frills instead of digits. Until DNA sequencing in 2013, many researchers thought the coelacanth was a sort of missing link between water-dwelling animals and those that first developed the ability to walk on land. As it happens, the lungfish turns out to be closer to that stage t...
