The Frogs

Frogs are amphibians. The characteristics of amphibians are:

They live near water. Their bare skin. Adults breathe through lungs and skin.

Their limbs are legs. In some cases, between the fingers of the legs extends a membrane that allows them to swim.

They are oviparous, that is born from eggs. They lay eggs in the water, because they have dried peel and ground.

The amphibian eggs are born larvae called tadpoles that living in the water. The tadpoles, have gills instead of lungs. Later the tail it's going small and appear lungs and legs. This change process called metamorphosis and  makes that the  adults amphibians capable of leaving the water.
