Pecten (bivalve)

Pecten is a genus of scallops, marine bivalve molluscs in the family Pectinidae, commonly known as scallops. They are characterized by their fan-shaped shells, radial ribs, and the presence of a prominent "ear" on either side of the hinge. These "ears," also called auricles, are usually unequal in size.

Pecten scallops are found in oceans worldwide, inhabiting a range of depths from shallow waters to deeper offshore environments. They are filter feeders, straining plankton and other organic matter from the water column. They are also known for their ability to "swim" by rapidly clapping their shells together, expelling water and creating a jet propulsion effect. This allows them to escape predators or move to more favorable locations.

The shells of Pecten scallops are often brightly colored and intricately patterned, making them popular with collectors. They are also an important food source in many cultures. The adductor muscle, which is responsible for closing the shell, is the edible portion most commonly consumed.

The species Pecten maximus, commonly known as the Great Scallop, is a commercially important species harvested extensively for food. Different species of Pecten can be identified by variations in shell shape, rib pattern, and coloration. Pecten species play an ecological role in benthic communities and contribute to the overall biodiversity of marine ecosystems.
