Life Cycles of Frogs

What is a Frog? A frog is an Amphibian. Amphibian means “double life.” They live the first part of its life in water. They live the last part of its life on land.

What is a Life Cycle? A life cycle is a set of changes animals go through as they grow.

First Stage: Eggs. Frog eggs look like tiny clear blobs with black centers. The clear jelly is the shell of the egg. It protects the tiny frog and keeps it warm.

Second Stage: Tadpoles Tadpoles have a head and tail. Like fish, tadpoles have gills for breathing underwater. Tadpoles eat plants. They are herbivores. As it changes, the tadpole grows back legs, then front legs. Then it’s tail shrinks. It looses its gills and lungs grow.

Third Stage: Froglets Froglets look like small adults with a small tail. Froglets begin to leave the water and go on land. Froglets begin to eat insects. Froglets are now carnivores.

Fourth Stage: Frog A frog is full grown when it does not have a tail. Frogs can have babies. The life cycle continues.
