Pectinidae

Pectinidae is a family of bivalve molluscs commonly known as scallops. These marine bivalves are characterized by their fan-shaped shells, which are typically equilateral and have distinct radial ribs. Unlike many other bivalves, scallops possess a single muscle that closes their shells, and this adductor muscle is often the edible part. Many species of Pectinidae are notable for their vibrant shell colors and patterns. A unique feature of scallops is their ability to move by rapidly opening and closing their shells, creating a jet of water that propels them through the water. They also have multiple simple eyes arranged around the edge of their mantle, allowing them to detect movement and light. Scallops are found in marine environments worldwide, inhabiting a range of habitats from shallow coastal waters to the deep sea. They are filter feeders, straining plankton and other small organic particles from the water. The family includes many commercially important species, such as the Atlantic sea scallop and the Pacific giant scallop, which are highly valued as seafood.
