Molluscs {bivalve}| (Pelecypoda) can have two shells, hinged at one side, no foot, one tube and valve that takes in water, and siphon tubes that send water out. Gills filter flowing water. Mucus carries food to mouth. Bivalves include oysters, clams, mussels, cockles, and scallops. Foot comes out of shell for movement. Clams and mussels burrow. Oysters do not move. Scallops move by clamping shells shut.
