This episode we take a look at the Gaboon Viper… or is that a toad? Looking at a couple of papers, we check out the characteristics of Gaboon Viper skin, and how a smart toad may be harnessing the looks of a viper to stay safe. Species of the Bi-week returns and continues our African toad journey. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com
