1 From Tadpole to Frog By Joanne Longley

2 Eggs Frogs lay very large numbers of eggs as many are lost to predators. Some frogs tend to their eggs but most leave the slippery mass of frog spawn.

3 Hatching About 6-21 days after being fertilized, the egg will hatch.
After hatching, the tadpole still feeds on the remaining yolk. The tadpole consists of poorly developed gills, a mouth, and a tail.

4 Getting Around Young tadpoles stick themselves to floating weeds or grasses using sticky organs between its' mouth and belly area. 7 to 10 days after the tadpole has hatched, it will begin to swim around and feed on algae.

5 Growing Pains After about 4 weeks, the gills start getting grown over by skin and eventually disappear. The tadpoles grow teeth which help them grate food. They can be fairly social creatures; some even interact and school like fish.

6 Look Ma, I Got Feet! After about 6 to 9 weeks the head becomes more distinct and feet start to appear. Their diet now includes larger items like dead insects and plants.

7 Awkward! After about 9 weeks, the tadpole looks like a small frog with a really long tail.

8 Getting There! At 12 weeks, the tadpole has only a small tail stub and looks like a miniature version of the adult frog.

9 Young Adult The frog will live mostly on land, with occasional swims.
The tiny frogs begin to catch and eat insects and worms.

10 And the process starts all over again.
