The garden snail comes out mostly at night to feed on leaves and other plant food. The snail’s mouth is under its head. It has no chewing jaws. To help it get its food, the snail’s mouth is equipped with a special tongue that is covered with hundreds of tiny teeth.
It is called the “radula” (RAJ-uh-luh). The rasp-like radula shreds and scrapes bits of food into the snail’s mouth as the snail crawls along. The snail finds its food with two pairs of tentacles on its head. The shorter pair is used for smelling on the tip of each of the longer tentacles is an eye. – Dick Rogers
