In early spring, a female frog lays thousands of eggs in a lake or pond. A few days or even a few weeks later, tiny wiggly tadpoles come out of the eggs.
The tadpoles swim about, nibbling at all plants. They still breathe with gills, like fish. But lungs for breathing air are growing in their bodies.
In time, the tadpoles grow little legs. Many tadpoles are eaten by fish and water insects.
After several months, the tadpoles can leave the water and breathe air with their lungs. They are now young frogs. Their short, tadpole tails shrink away and vanish.
By summer’s end, the frogs are fully grown. During winter they will hibernate at the bottom of the pond. In the spring, the females will lay new eggs.
The life cycle of many frogs takes the animals from egg to tadpole to frog in a matter of months.
