a genus of sea invertebrates, class Bivalvia. The shell is round with a straight hinge edge. The surface is covered with radial ribs fanning out from the top. The shell valves close through contraction of a single strong muscle. Young Pecten attach to seaweed or other underwater objects by means of a byssus, but mature Pecten lie freely on the bottom. Pecten are able to “leap” by forcibly ejecting a stream of water from the shell. Some types have commercial value since the muscle is used for food. The genus Pecten comprises dozens of species and has been divided into several smaller genera in recent years. P. maximus and Flexopecten glaber inhabit the Black Sea. Mizuhopecten jessoensis is found in the Seas of Japan and Okhotsk; its diameters reach 17 cm. Chlamys islandicus(up to 7.7 cm long and 8 cm high) and Propeamussium groenlandicum(up to 3.4 cm long) are found in northern seas.
