•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.
