Pecten maximus

Pecten maximus, commonly known as the Great Scallop or King Scallop, is a species of scallop, a type of marine bivalve mollusk in the family Pectinidae. This species is native to the northeastern Atlantic Ocean, specifically from the north coast of Norway to the Iberian Peninsula.

Description

The Great Scallop can grow up to 17 cm in size, making it one of the largest scallop species. It has a fan-shaped shell with radiating ribs and a slightly wavy edge. The upper shell is usually reddish-brown, while the lower shell is pale or white.

Habitat and Distribution

Pecten maximus is found in the northeastern Atlantic Ocean, from the north coast of Norway to the Iberian Peninsula. It inhabits a variety of habitats, from sheltered bays to exposed coasts, and from the intertidal zone to depths of up to 100 meters.

Diet

The diet of Pecten maximus consists mainly of plankton, which it filters from the water using its gills.

Reproduction

The Great Scallop is a hermaphrodite, meaning each individual has both male and female reproductive organs. Spawning usually occurs in summer, and the larvae are planktonic.

Economic Importance

Pecten maximus is commercially important and is harvested for its meat. It is a popular seafood in many parts of Europe, particularly in France, where it is a key ingredient in dishes such as Coquilles Saint-Jacques.

Conservation

While Pecten maximus is not currently considered threatened, it is vulnerable to overfishing and habitat degradation. Conservation measures include size limits and restrictions on harvesting during the breeding season.
