Most modern turtles are pretty good in the water, but only some are truly ocean-dwellers. This episode, we explore the unique and diverse lifestyles and anatomy of modern sea turtles, then we take a tour of turtles through time, visiting the surprising number of ancient lineages that have taken to the seas and the surprising forms some of them have taken.

Couple years ago in the summer, we did marine crocs and we did sea snakes. Now... Uh, oh, we've also done a bunch of the other marine rept- Mm-hmm We did ichthyosaurs, we did plesiosaurs, we did mosasaurs. Sea turtles. We're gonna talk about what makes a turtle well-suited for living in the ocean. We'll discuss our modern-day species, and then we will go through a history of sea turtles throughout the fossil record, and evolutionary history of the multiple times that turtles have done this. Really interesting fossil record stuff.

David· Host1:28
