Tadpole

Description:

Tadpoles is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestrial.

Habitat:

In the water (mostly pond)

Notes:

Tadpoles breathe and absorb oxygen when they are in the water, whereas fully developed frogs and toads can breathe on both land and water. Tadpoles breathe through gills, which is another characteristic that makes them similar to fish. As they grow, they eventually lose their gills.
