This bi-week we are talking about some underwater cannibals, with a very stylish new species of salamander thrown in too. We also answer a patreon question about arboreal snakes, and how they avoid blood rushing out of their heads.

073 Lizards of the Night

Lizards of the night - Night lizards - Xantusiidae. We take a close look at the genetics of the island night lizards, and explore some new options for reptile home range estimations. Luck would have it, a new night lizard is our Species of the Bi-week. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com

069 Freezing Frogs

We’re back and exploring the toughest of frogs; those frogs braving the harsh northern conditions that literally freezes them to the bone. How do they manage this incredible feat?
