Ladonna Stinson, age 7, of Charlotte, No. Carolina, for her question:

Do frogs have teeth?

A frog does not need teeth because usually he grabs his food in small helpings and swallows it whole. However, he has one row of small teeth, just in case he needs to hold onto a frisky fly. These little teeth are in his upper jaw. They are not very strong and rather loose. Sometimes he loses one, but this does not matter very much. A new one grows in to replace the old one. Ile has a very strong lower jaw, padded with tough gums. This is what he uses to grab his food and the teeth in his upper jaw help him to hold it.

Mr. Frog is a whiz at catching flies and bugs as they go buzzing by. For this job he has a very long sticky tongue. One end of this remarkable tongue is fixed just inside his big froggy mouth. He can flick it out, catch a fly and curl it back inside, almost too fast for your eyes to see. Then he gulps down the fly, smiling his froggy smile.
