Clams, Mussels and Oysters are common types of Mollusks. Mollusks are invertebrates that live in ocean, freshwater and terrestrial habitats. It is estimated that there are as many as 120,000 different species of mollusk.There are several different classes of mollusk.The most common mollusks are the gastropods (e.g., snails and slugs), the cephalopod (e.g., octopus, squid and cuttlefish) and the bivalve (e.g., clam, muscle, oyster and scallop).The Giant Squid and the Colossal Squid are the largest animals without a backbone.he most common mollusks are the gastropods (e.g., snails and slugs), the cephalopod (e.g., octopus, squid and cuttlefish) and the bivalve (e.g., clam, muscle, oyster and scallop).

Characteristics of Mollusks. Mollusks are soft-bodied invertebrates with bilateral symmetry and usually one or two shells. Their organs are in a fluid-filled cavity; the word mollusks in Latin means soft.Most of the mollusks live in water but some live on land. There are more than 110,000 species that have been identified.A theoretical, idealized mollusk would crawl on a single flat, muscular foot, and the body would have at least a suggestion of a head at one end and an anus at the other.ost of the mollusks live in water but some live on land.
