Snails belong to a Class known as Gastropods, which make up the largest class ofMollusks. Snails grow by increasing their swirling body while producing a protectiveshell. This shell protects their soft body from predators. They will use a pad, orfoot, that extends from their shell which allows them to drag their shell along. Asthey drag their shell often times their mouth and eyes can be seen coming out fromthe opening of the shell. When frightened or sleeping this opening can be protectedby an operculum, which is a hard protective cover that acts like a door to theshell. Snail identification is based on the color, shape, and pattern of theirshell.
