Carolyn Womack, Age 13, Of Houston, Tex., for her question:

Do frogs have teeth?

Frogs and toads, as everyone knows, have very wide mouths and a lot to say for themselves. You would expect to find rags of teeth in their jaws, but the toads have no teeth at all. Their water loving cousins,, however, do have teeth behind their froggy smiles. These teeth develop after the tadpole stage.

A newly hatched tadpole sticks helpless to a water weed by means of a tiny sucker. In a few days, the sucker becomes a small, round mouth and the tadpole nibbles his food.. When he changes into a frog, he gets a froggy type mouth, but while the change is going on, he lives on the fat stored in his tail and does not eat at all.
