Main Menu

Frogs lay their eggs in water or wet placesFloating clumps of eggs are called frog spawnOnce laid, the eggs are surrounded by a

jellylike covering to protect them

Eggs

Main Menu

After 21 days the embryo leaves the jelly shell and attaches to a weed in the water

The embryo grows until it is big enough to break free into the water

This can take from 3 days to 3 weeks depending on the species of frog

Tadpole

Main Menu

After about 5 weeks, the tadpole starts to grow hind legs

This is followed by the growth of forelegs The tails become smallerLungs begin to develop Mouth widens

Tadpole with legs

Main Menu

11 weeks after an egg is laid, a fully developed frog emerges from the water.

The frog will now live mostly on land, but returns to the water to swim.
