Aequipecten
Aequipecten is a genus of saltwater clams, marine bivalve mollusks in the family Pectinidae, the scallops. Members of this genus are commonly called “scallops”. These scallops are known for their distinctive fan-shaped shells with prominent ribs and prominent ears. The genus Aequipecten includes several commercially important species, including the European scallop (Aequipecten opercularis) and the American scallop (Aequipecten irradians).
Common Names
Species within the genus Aequipecten are often referred to simply as "scallops." However, depending on the specific species and region, they may have other common names. For example, Aequipecten opercularis is known as the "queen scallop" in the UK.
Characteristics
Members of the genus Aequipecten share several key characteristics:
- Shell Shape: Fan-shaped with prominent ribs and ears (projections at the hinge).
- Size: Varies by species, but generally range from a few centimeters to over 20 centimeters in length.
- Coloration: Shell color can be white, cream, pink, orange, or brown, often with intricate patterns.
- Eyes: Scallops possess numerous small blue eyes along the edge of their mantle, allowing them to detect movement and light.
- Locomotion: Scallops are able to swim by rapidly clapping their shells together, propelling themselves through the water.
Environments
Aequipecten species are found in marine environments, typically inhabiting sandy or muddy bottoms in coastal waters. They are often found in shallow water, though some species can live at depths of up to 100 meters.
