Class:
Bivalvia - clams, oysters, scallops and mussels
Bivalves are soft-bodied animals that are protected by two hard
shells, hinged together. Most are completely enclosed by the shell,
the two valves of which are joined by an elastic ligament, and by
two sheets of tissue called the mantle. Bivalves have no head. They
feed on phytoplankton by pumping water across the gills and trapping
food particles that are then moved to the mouth. Bivalves are found
in most parts of the ocean from the intertidal zone to abyssal depths.
