001 Cool Colours and Cryptic Camo

On this inaugural episode of Herpetological Highlights we discuss colour changing Bearded Dragons, the temperature efficiency of Bluetongue Skinks, and how snake camouflage may have driven primate evolution. Our Species of the Bi-week is a sexually dichromatic snake from India. FULL REFERENCE LIST AVAILABLE AT:
