Life Cycle Main Menu
Eggs • Frogs lay their eggs in water or wet places • Floating clumps of eggs are called frog spawn • Once laid, the eggs are surrounded by a jellylike covering to protect them Main Menu
Tadpole • 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 Main Menu
Tadpole with legs • After about 5 weeks, the tadpole starts to grow hind legs • This is followed by the growth of forelegs • The tails become smaller • Lungs begin to develop • Mouth widens Main Menu
Adult Frog • 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. Main Menu
