AMPHIBIANS AND REPTILES

Amphibians and reptiles – particularly crocodiles and snakes – tend to get bad press, but most are generally harmless to people and are of great ecological value. Both maintain their body heat using external sources, for instance by basking in the sun, meaning they are prolific in warm climates and tend to be poorly represented at high altitudes.
