Snail

The humble garden snail is a mollusk that bears a univalve (one-piece) shell. A typical snail shell is cone-shaped and spirally coiled. There are thousands of species of snails, no two species having shells of exactly the same shape or color. Some shells are drab, varying from gray to brown. This one found in our back garden is actually quite attractive.

A snail gets around on its foot. But it's not the kind of foot you might be thinking of. A snail's foot is actually a long, muscular sticky, slimy organ that spreads out under the snail's body.
