Summary

Turtles are so weird and wonderful. They're unlike any other living reptiles, mostly because they've turned their entire torso skeleton into an armor-home. A glimpse into the fossil record reveals that they've been this way for more than 200 million years. And yet, with all our data on living and extinct turtles, they remain one of the most mysterious and confusing living vertebrate groups. Here's an episode about all of that. In the news: death rolls, one huge predator, one weird crab, the Gray Site rhino, and a poop snake.
