Reptiles have literally been around for an age - over 340 million years!
They saw the dinosaurs come and go, and even saw the first birds fly. However, in the last 50 years, many reptile species have been driven to extinction and many more will disappear in the next few years unless we do much more to help save them.
We have over 50 fascinating reptile species including the Komodo dragon, the world's largest lizard, and also the tuatara, a living fossil which can live for over 100 years.
Although reptiles are cold-blooded, most are able to control their body temperature by moving between hot and cold areas (usually by basking in the sun or seeking shade). Our reptile habitats are carefully designed to allow each animal to choose their ideal temperature.
