Pectinidae 海扇蛤科Shell small to large-sized, consisting of flabelliform or subcircular disk and auricles, more or less inequivalve. Coloration variable, commonly darker in left valve. Byssal notch and ctenolium exist in young byssate stage, but many species become free-living (or sedentary) with growth. Outer ligament attaching to the whole dorsal margin; resilium completely internal, placed below umbo.Surface commonly ornamented with radial ribs, and immature shells occasionally covered with two kinds of microsculpture (shagreen sculpture and Camptonectes striae). In both valves, outer layer is mostly composed of foliated calcite, and the inner layer consists of crossed-lamellar aragonite, though in many cool-water species the innermost part again shows foliated microstructure. Periostracum very thin. Monomyarian; quick muscle well developed in swimming species. Filibranchiate. Numerous tentacles and eyes exist on the mantle margin. Heart penetrated by the rectum. Some species hermaphroditic.
