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

3
  • Frogs have a life cycle with two parts, living in
    water as tadpoles and on land as adults.

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.

Tadpole
  • The second stage of the frog life cycle is the
    tadpole.
  • Hatched tadpoles have gills for breathing in the
    water.
  • They have a tail, but no legs.

8
As a tadpole grows, lungs begin to form.
9
Froglet
  • The next stage of the frog life cycle is the
    froglet.

10
Their back and front legs begin to grow. These
parts allow the adult frog to live on land.
11
Adult Frog
  • Once the lungs form and begin to work, the gills
    and tail disappear.

12
The adult frog is now ready to live on land.
