Description:- Argopecten gibbus, the Atlantic calico scallop, is a species of medium-sized edible marine bivalve mollusk in the family Pectinidae, the scallops. This species was once the basis of an important fishery, but in recent years catches have been low. This species grows up to three inches in maximum width, and is similar in shape and sculpturing to the Atlantic bay scallop. Both valves of the shell are cupped. The shell near the hinge is extended into "ears", as is the case in all scallops. The shell of the Atlantic calico scallop has about 20 radial ribs, which are sometimes roughened by growth lines.
