Physical Characteristics:
The Pectinidae (from Latin pecten meaning comb), common name "scallops", are a family of saltwater bivalve mollusks. They are hermaphrodite, and the male gonads mature first. There are numerous species of various sizes in all of the oceans, and a number species are of commercial importance. Some pectinidae live attached by means of a filament they secrete, others are simply recumbent, but a form of jet-propulsion created by repeatedly clapping their valves closed can propel them swiftly but erratically through the water when they sense the presence of a predator such as a starfish.
