The word refers to "bivalve," which is a type of shellfish characterized by having two hinged shells, or valves, that protect its soft body. Common examples of bivalves include clams, oysters, and mussels. They typically live in aquatic environments and are known for their ecological role as filter feeders. Bivalves are also significant in various culinary traditions and are often harvested for food.
Bivalves are mollusks belonging to the class Bivalvia. They typically have two-part shells, with both valves being symmetrical along the hinge line. The class has 30,000 species, including scallops, clams, oysters and mussels. Other names for the class include Bivalva, Pelecypoda, and Lamellibranchia. Bivalves are exclusively aquatic; they include both marine and freshwater forms. However some, for instance the mussels, can survive out of water for short periods by closing their valves. Bivalves are unique among the mollusks for lacking a radula; they feed by siphoning and filtering large particles from water. 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, such as scallops, can swim.

Bivalves are eaten by a variety of predators in aquatic ecosystems, including fish, crabs, sea stars, birds, and some marine mammals like otters. These animals have adapted to crack open the shells of bivalves to access the nutritious soft tissues inside.

Clams, oysters, and mussels are in the shellfish family, under the subheadings of mollusks and bivalves. Mollusks include abalone and scallops as well as clams, oysters, and mussels. Bivalves are any creature with a soft body that lives between two hinged shells.
Most do so by simply closing their shells, however some bivalves can clap their shells together and "swim" away from danger.
