• The skin of amphibians is very thin and must
  always be kept wet because amphibians breathe
  through their skin. The do have lungs, but their
  lungs are small and are not used very much.
  Fertilization of the eggs is external, taking
  place in the water. The eggs are covered with
  jelly to protect them. The larvae, called
  tadpoles, are aquatic. They slowly change
  (metamorphose) into the adult amphibian which
  lives on land but always near water. Examples of
  amphibians are the frog and the newt.

• The body of a reptile is covered in hard
  scales. Reptiles live on land, although many of
  them swim well and may feed in water, such as
  some snakes and lizards. They breathe using
  lungs. When male and female mate fertilization is
  internal. The female lays soft-shelled eggs which
  are often buried in sand or in the earth to
  protect them while the young develop inside.
  Examples of reptiles are crocodiles, snakes and
  lizards.
