014 Crocs


Crocodylians have been around for a while and they know what they’re doing. In this episode we discuss what they do when they’re ticked off, and how the massive, fascinating, and largely unknown Tomistoma is getting on in SE Asia. As always, we end on a new species, and this time it’s a fractious new species of something crocodile-like. FULL REFERENCE LIST AVAILABLE AT:
