Are frogs amphibians that live their life under water?

Frogs are in fact amphibians. The word amphibian is from the Greek language meaning “both lives.” A frog’s life cycle includes a metamorphosis. Adult frogs lay their eggs in water. Once the eggs hatch, a tadpole emerges. When the tadpole hatches from the egg it has a tail with no arms. Tadpoles are restricted to the water and have gills to breathe. After about a week, the tadpole’s body starts to change. After about six weeks, the external gills disappear; and after eight weeks, hind legs are formed. After about 12 weeks, front legs are formed and the tail begins to shrink. When the tail disappears, the frog will hop out of the water and live on land. The adult frog will live its life on land, only returning to the water to lay eggs.
