011 Survival of the Vipers

00:0000:00

Vipers are found in numerous corners of the globe, and in this episode we explore a little about how they’ve managed it. Starting with pit viper’s use of their heat sensing abilities, moving on to viper reactions to climatic shifts, and finishing up with how they are doing now. Naturally our Species of the Bi-week is a new viper, this time from Africa. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com
