Still image from: Journey to the Microcosmos: The Aquatic Snails That Leave a Path of Destruction

Snails are members of the Mollusca phylum, which includes oysters, clams, octopuses, and squids. Not all of these creatures make shells. Those that do produce shells primarily use calcium carbonate, a hard mineral that protects the softer animal within. The snails featured in this episode reproduce quickly and devour anything in their path. Part of the "Journey to the Microcosmos" series.
