There are more than 3000 species of lizards, making them the largest group of reptiles. They have dry, scaly skin and clawed feet. Lizard tails are fragile and easily break off. This can be beneficial in that it allows the lizard to escape from predators. Some lizards use their tails to store fat reserves.
Most lizards eat insects.
Some are vegetarians and a few will eat small mammals and eggs. They are found in tropical and sub-tropical habitats. Lany lizards can defend themselves by biting and there are two species that are venomous. The scaly skin helps protect against predators. The chameleon can change its color to match that of its environment.
