Episode 209 - Chimaeras - Video

0 Views
You might know them as ghost sharks, rat fish, or spook fish. Chimaeras are close cousins of sharks and rays, equipped with distinctive and unusual features in their fins, teeth, and reproductive structures. In today’s oceans, chimaeras are rare and easy to miss, but their extended family includes some of the most diverse and iconic fish of the Paleozoic seas. In this episode, we’ll explore the traits that set chimaeras apart, we’ll take a tour through their ancient relatives, and we’ll investigate what their most famous cousins were doing with their strange spiral rows of teeth.

In the news: Baltic herrings, Cambrian arms race, pterosaur tails, and early dinosaurs.
