Scallop

A scallop ( /ˈskɒləp/ or /ˈskæləp/) is a marine bivalve mollusk of the family Pectinidae. Scallops are a cosmopolitan family, found in all of the world's oceans. Many scallops are highly prized as a food source. The brightly colored, fan-shaped shells of some scallops, with their radiating fluted pattern, are valued by shell collectors and have been used as motifs in art and design.
