All about Reptiles
Reptiles are cold-blooded animals with dry, scaly skin. They rely on the environment to control their body temperature, which is why you often see lizards basking in the sun. Snakes, lizards, turtles, tortoises and crocodiles are all reptiles.
Most reptiles lay leathery or hard-shelled eggs on land. Some, such as some snakes and lizards, give birth to live young. Reptiles have been on Earth for over 300 million years.

Frequently asked questions about Reptiles
Are reptiles always cold?
Not always. Reptiles warm themselves in the sun and cool down in the shade, which is called behavioural thermoregulation.
Do snakes have bones?
Yes. Snakes have a backbone with many ribs, which allows them to move without legs.
What is the difference between a lizard and a snake?
Most lizards have four legs and eyelids that move, while snakes have no legs and no movable eyelids.
