Episode 117 - Crabs and Carcinization

What exactly is a “crab” anyway? One answer is that they are among the most diverse and successful living arthropods. Another answer: they are many different groups of crustaceans that have converged on a crabby body plan. In this episode, we discuss the diversity and evolution of “true crabs,” the incredible phenomenon of carcinization that keeps creating crabs, and what it really means to be a “crab.”

In the news: poop beetles, Arctic dinosaurs, Dragon Man, and an ancient shark attack.
