Did you know that a frog starts its life in the water? When a frog is young, it can't jump at all because it doesn't have legs! In this lesson, we will learn about the life cycle of a frog.

The Double Life of a Frog

One of the most interesting things about frogs is that they spend part of their life in the water and part of their life on land. Animals that spend the first part of their life in the water and the second part of their on land are called amphibians. During the early stages, frogs and other amphibians have gills for breathing, just like fish. Then, they develop lungs so they breathe on land like we do.

Stages in the Life Cycle of a Frog

Frogs lay eggs, like birds and some other animals. But, unlike bird eggs, frog eggs are usually very wet and soft and must be laid in the water or somewhere where it is very damp. These eggs are usually small. It helps if the eggs are in the water, because the baby frogs will hatch and need to be in the water right away.

Once they hatch, young frogs are called tadpoles. Tadpoles are the earliest stage in the frog life cycle. Tadpoles have flat tails for swimming and gills for breathing underwater. If you haven't seen a tadpole before, you might even think it looks like a small fish. Tadpoles use their flat tails for swimming just like a fish uses its fins. You won't see a tadpole jumping around, because it doesn't have legs yet. If you ever have the chance to watch tadpoles grow up, you will notice them change from day to day. They are getting ready for what happens next!
