Reptiles are a class of cold-blooded (in the traditional sense) animals that include the turtles, crocodiles, snakes and lizards. They first appeared on earth during the Carboniferous around 312 million years ago and a staggering 10,000 species have since been described. The majority (95%) of these species sit within the Squamata group that holds the lizards, snakes and "worm lizards".
