  3. Metamorphosis • Metamorphosis is the changes that a frog goes through during its life cycle. • There are four main stages in the life cycle of the frog.

  4. Egg • The first stage in the life cycle of the frog is the egg. • A frog lays many eggs at one time. • The eggs are covered with a jellylike coating.

  5. Tadpole • The second stage of the frog life cycle is the tadpole. • A tadpole or polliwog is the product of a hatched frog egg. • Tadpoles, like fish, breathe with gills. • Unlike fish, tadpoles use their tail to swim. • During this stage of the life cycle, frogs spend all of their time underwater.

  6. Tadpole with legs • In stage three, a tadpole begins to develop legs and arms. • The body grows larger and the head is more apparent to the human eye. • The tadpole continues to breathe using gills.

  7. Adult Frog • Once the lungs form and begin to work, the gills and tail disappear. • The adult frog is now ready to live on land.
