Life Cycle of a Frog
00:00:01
The life cycle of a frog has four stages.
00:00:11
First, eggs.
00:00:19
Second, tapu.
00:00:21
Third, metamorph.
00:00:23
Fourth, frog.
00:00:24
The female frog lays thousands of jelly-covered eggs in the water.
00:00:27
It takes about ten days for the eggs to hatch.
00:00:33
Eggs hatch into tiny tadpoles. They swim, eat and grow. Tadpoles use their tail to swim.
00:00:38
The froglet continues to grow and frog legs appear. The lungs begin to develop. Its eyes and mouth grow larger and the tail keeps shrinking.
00:00:52
As the tadpole grows, its sprout legs, the froglet, as it is now called, grows and its tail begins to shrink.
00:01:03
When the tail finally disperses, the froglet becomes a frog.
00:01:19
It can now leap onto land and leap out of the water.
00:01:26
When spring arrives, the adult frog will find a maze and lay another generation of frogs.
