As a group, scallops have been around since the mid Triassic, and are still part of marine ecosystems today. When one eats a ‘scallop’ as seafood, what you are typically eating is the adductor muscle of the scallop.

Unlike most bivalves, scallops are free swimmers, and can move at surprising rates of speed thanks to their powerful adductor muscle. Scallops can generate pearls like oysters and clams, however, their pearls do not tend to be as shiny or attractive as those from oysters. In the photo below of a living scallop, the blue spots are the eyes.
