Bivalvia is a class of mollusks that all have two shells. It includes the clams, oysters, scallops and mussels. There are over 20,000 species of bivalves around the world, and probably thousands not yet discovered.Nearly all of them live in salt water, but a few groups have evolved to live in freshwater.Bivalves have two shells that they can close together tightly for protection, with their whole body inside.here are over 20,000 species of bivalves around the world, and probably thousands not yet discovered.

Best Answer: Some bivalves are epifaunal: that is, they attach themselves to surfaces in the water, by means of a byssus or organic cementation. Others are infaunal: they bury themselves in sand or other sediments. These forms typically have a strong digging foot.Some bivalves can swim. Chitons creep along slowly on their muscular feet and cling to rocks. Most snails move by gliding along on their muscular foot, which is lubricated with mucus.This motion is powered by succeeding waves of muscular contraction which move down the undersurface of the foot.ome bivalves can swim.
