There are an estimated 50,000 species that belong to the invertebrate group known as Mollusca. Members of this diverse group have soft bodies which are composed of a ‘head’ region and a “foot” region.

Included in the Mollusks are the widely-known groups of bivalves (clams, mussels, scallops), cephalopods (cuttlefish, nautilus, octopuses and squids), and gastropods (limpets, snails, slugs).
