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).

The most popular mollusk at the Newport Aquarium is the Giant Pacific Octopus.
