Scallop is a common name that is primarily applied to any one of numerous species of saltwater clams or marine bivalve mollusks in the taxonomic family Pectinidae,the scallops. They are a cosmopolitan family of bivalves,found in all of the world's oceans,though never in freshwater. The majority of species live recumbent on sandy substrates,and when they sense the presence of a predator such as a starfish,they are able to escape by swimming swiftly but erratically through the water using a form of jet propulsion created by repeatedly clapping of their shells together. Many species of scallops are highly prized as a food source,and some are farmed as aquaculture. The word scallop is also applied to the meat of these bivalves when it is sold as seafood.
