Despite existing on the planet for millions of years with minor morphological changes, crocodiles are having a difficult time in a new human dominated world. However, there are success stories. This episode we take a look at the rebound of American Crocodiles, and also explore how long herpetofauna live for.

Animals come in many sizes, great and small. But all are subject to the laws of physics. In this episode we look at how the tiniest of frogs are too small to elegantly jump. Species of the Bi-week returns for an even fresher, more chocolatey frog.

A phylogenetic paper focused episode looking at the longest snake of them all: Reticulated pythons. Are all reticulated pythons part of one big happy whole, or do the hundreds of islands they inhabit mean pythons represent just as many sub-species? Species of the Bi-week is a wonderfully lemon-soaked lizard.
