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.
