Life Cycle of a Frog: First Week

A female frog lays 5,000 to 6,000 eggs in water.

Each egg is only 1.5 mm in diameter.

When the eggs are 6 days old you can see the tiny tadpoles inside of the eggs.

Life Cycle of a Frog: 6-9 Days Old

The tadpoles come out of their eggs.

They are now 8 mm long. They are adapted to living in

water. They take in oxygen from the

water through their gills. They have long tails to help

them move through the water to hunt for food.

Life Cycle of a Frog: 60-84 Days Old

The tadpole now has back legs. It uses it’s legs and tail to move around in the water.

Its legs will help it move around on land.

It begins looking more like a frog.

The last thing to disappear is the tadpole’s tail.

It gets smaller and smaller until it is gone.

Life Cycle of a Frog: Adult Frog

An adult frog doesn’t look anything like its old tadpole self.

Adult frogs breathe air through lungs-not gills.

They spend most of their time on land-not in water.

They can jump on land and swim in water.
