THE LIFE CYCLE OF FROG

THIS IS THE DIAGRAM OF THE FROG LIFE CYCLE

FROG SPAWN Frogs lay so many eggs. From

the three thousand eggs that

one female lays, only around

five will become adult frogs. The

rest of the eggs or tadpoles may

be eaten by birds, fish, newts,

water beetles, dragonflies or

simply dry up before hatching.

The frogspawn that you see

floating in ponds is made up of

thousands of single eggs, each

one having a tiny black tadpole

embryo surrounded in jelly.

Frogspawn will take about six to

twenty one days to hatch after

they have been fertilized.

TADPOLESconsist of gills, a mouth

and a tail. Immediately after hatching, they will usually stick themselves to weeds or grasses in the water. After about seven to ten days, the tadpoles will start swimming around and feeding on algae. After about six to nine weeks, the tadpoles start to absorb their tails and grow legs and arms. Now the tadpoles will eat plants and dead insects floating on the water. 

FROGLET

By approximately twelve weeks, the tadpole has a tiny tail stub and will soon leave the water. 

FROG

Between twelve to sixteen weeks, the froglet totally absorbs its stubby tail and leaves the water becoming an adult frog.

And the cycle

begins again in

the spring.
