•Reptiles are vertebrates that have

scales and breathe by the use of lungs.

•Examples are

snakes, lizards, turtles, tortoises, alliga

tors and crocodiles.

All reptiles are cold-blooded.

Many reptiles may move to a number of

places during the day to escape the

extreme temperatures.

Bodies are covered by scales to prevent

the loss of water.

Reptiles are different from amphibians

because they use their lungs to breathe

the moment they are born.

Most reptiles will return to land to lay their

eggs.

A reptile’s egg has a hard protective shell

to prevent it from losing water.
