Turtles, snakes, crocodiles, and lizards
are all reptiles. Reptile skins are dry, scaly, and quite
waterproof. Reptiles do not need to live in damp
places. Many live in deserts. Reptiles lay eggs.
Reptiles lay eggs that have a hard or leathery
shell. The eggs are laid on land. Most reptiles do not
look after eggs and young. Eggs are laid and left to hatch
on their own.
Turtles are one of the oldest
reptiles. There are 250 kinds of turtles. Land
tortoises are usually slow-moving plant eaters. Sea turtles
and freshwater turtles are good swimmers and are mostly hunters.
Crocodiles also swim well, and are the
largest living reptiles and fierce hunters. There are 25
kinds of crocodiles.
There are about 3,000 kinds of snakes and
3,000 kinds of lizards. Most lizards are small and feed on
insects. They are found in the tops of trees to burrows
underground. Snakes are hunters and swallow their prey whole.
