Lizards, snakes, tortoises...
All reptiles breathe through lungs and have skin covered with scales.
Most of them live on land and walk using their legs.
However, some reptiles are different:
- Snakes have no legs and they slither.
- Tortoises and turtles have a hard shell to protect their body. Turtles are aquatic, but they breathe oxygen from the air.
- Crocodiles are protected by bony scutes where their scales are very thick.
