Species of bivalve mollusc
Argopecten irradians, commonly known as the Atlantic bay scallop, is a species of bivalve mollusc in the family Pectinidae. This species is native to the western Atlantic Ocean, particularly along the eastern coast of the United States.
Description[edit]
Argopecten irradians is characterized by its fan-shaped shell, which is typically about 5 to 10 centimeters in diameter. The shell is composed of two valves that are hinged together, allowing the scallop to open and close. The exterior of the shell is often ribbed and can vary in color from gray to brown, with some individuals displaying patterns of stripes or spots.
Habitat[edit]

Life Cycle[edit]
The life cycle of Argopecten irradians includes several stages, beginning with the release of eggs and sperm into the water column. Fertilized eggs develop into free-swimming larvae, which eventually settle to the bottom and metamorphose into juvenile scallops. As they mature, scallops develop the ability to "swim" by rapidly clapping their shells together, a unique behavior among bivalves.

By filtering plankton and other small particles from the water, scallops help maintain water quality and clarity. They are also an important food source for a variety of predators, including fish, crabs, and sea birds.
Economic Importance[edit]
The Atlantic bay scallop is highly valued for its meat, which is considered a delicacy. Scallop fisheries are an important economic activity in many coastal communities, particularly in the northeastern United States. However, populations of Argopecten irradians have declined in some areas due to overfishing, habitat loss, and environmental changes.
