Accession Number: NH.2000.1.533

This large, fan-shaped shell is a Great Scallop (Pecten maximus), also known as the King Scallop. It can reach up to 20 cm in diameter. The shell has strong radial ribs and is usually reddish-brown or cream in colour on the outside, with a smooth, often white interior. One valve is more domed than the other, allowing the scallop to rest flat on the seabed. Pecten maximus feeds on plankton, filtering its food from the surrounding water.

Location:
Northeast Atlantic, from Norway to the Mediterranean, living on sandy or gravelly seabeds.

Average Size:
Up to 20 cm in diameter.

Family:
Pectinidae (Scallops)

Species:
Pecten maximus

Ecological Role:
The Great Scallop plays an important role in benthic ecosystems as a filter feeder and a food source for marine predators. Its mobility helps it avoid predation, contributing to its survival.

Reproduction:
Great Scallops reproduce by releasing eggs and sperm into the water, where fertilisation occurs externally.

Conservation Status:
Pecten maximus is commercially harvested, and sustainable fishing practices are important to maintain healthy populations. Fisheries management and marine conservation areas help protect this species from overexploitation.
