The canarium urceus is a species of sea snail, a marine gastropod mollusk in the family Strombidae. The Little Bear Conch has a varied coloration of white, cream or brown with contrasting spotted color. Also, the presence of only shell will reduce the likelihood of the hermit crabs within the aquarium competing for a home. The bear conch shell is basically found in 3-5cm length with thicker shell and exhibits long and narrow body without a very broad flared portion. The Little Bear Conch shell opening is black, although in some, this may appear as just a black border around the edges of the shell's underside. The animal is greenish sometimes with white or beige spots. Like other conch snails, it uses its pointed operculum to hop along.
Conchs belong to a Class known as Gastropods, which make up the largest class of Mollusks. Conchs grow by increasing their swirling body while producing a protective shell. This shell protects their soft body from predators. They use a pad, or foot, that extends from their shell which allows them to drag their shell along. As they drag their shell often times their mouth and eyes can be seen coming out from the opening of the shell.
