The sixth episode of the SquaMates podcast—featuring some amazing new stories, including new iguanas and crocodiles, high-elevation herps, and some spectacular sea serpents! The show is hosted by Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak.

In this sixth episode, we talk about the many newsworthy papers published in the last month, from complex genomic modelling to some really amazing new species, including one crocodile that is new, and one that is not! Our main discussion is about sea snakes, their diversity and specialisations. Our #HERper is Grace Olive Wiley, a controversial but amazing herper of history.
