''Pecten maximus'' is characterized by its large, fan-shaped shell, which can reach up to 15 cm in length. The shell is composed of two valves, with the right valve being more convex than the left. The exterior of the shell is typically reddish-brown with radiating ribs, while the interior is smooth and white.


The shell's distinctive "ear" or "auricle" on either side of the hinge is a notable feature, aiding in the identification of the species. The animal itself has a series of eyes along the edge of its mantle, which are sensitive to light and movement, helping it detect predators.

Pecten maximus[edit]

Pecten maximus shell

Pecten maximus, commonly known as the great scallop or king scallop, is a species of marine bivalve mollusk in the family Pectinidae. This species is found in the northeastern Atlantic Ocean and is highly valued for its edible adductor muscle.

Description[edit]

Close-up of Pecten maximus

Pecten maximus has a distinctive fan-shaped shell with radiating ridges. The shell can grow up to 15 cm in length and is typically a reddish-brown color, although it can vary. The interior of the shell is smooth and white. The species is known for its ability to "swim" by rapidly opening and closing its shell, which propels it through the water.

Habitat and Distribution[edit]

Pecten maximus is found along the coasts of Europe, from Norway to Spain, including the British Isles. It inhabits sandy and gravelly substrates at depths ranging from the intertidal zone to about 100 meters. The species prefers areas with strong currents, which help to provide a constant supply of food.

Biology[edit]

Pecten maximus is a filter feeder, using its gills to extract plankton and other small particles from the water. It has numerous small eyes along the edge of its mantle, which can detect changes in light and movement, helping it to avoid predators. The scallop also has sensory tentacles that can detect chemical changes in the water.

Reproduction[edit]

Pecten maximus is a hermaphroditic species, meaning individuals possess both male and female reproductive organs. Spawning typically occurs in the spring and summer, when water temperatures rise. Fertilization is external, with eggs and sperm released into the water column. The larvae are planktonic and undergo several stages of development before settling to the substrate and metamorphosing into juvenile scallops.

Economic Importance[edit]

Capture production of Pecten maximus

Pecten maximus is an important species for commercial fisheries, particularly in the United Kingdom, France, and Ireland. The adductor muscle, known as the "scallop," is a popular seafood delicacy. The species is harvested using dredging techniques, although concerns about sustainability and environmental impact have led to increased interest in aquaculture and more sustainable fishing practices.

Conservation[edit]

Efforts to manage Pecten maximus populations include setting quotas, regulating fishing seasons, and establishing marine protected areas. Research into the species' biology and ecology is ongoing to ensure sustainable management and conservation of this valuable resource.
