Cancer pagurus, commonly known as the edible crab or brown crab. It is the largest European crab.
A mature adult may have a carapace width up to 25 cm and weigh up to 3 kg. It lives in the waters of the North-East Atlantic from Morocco to Norway on mixed coarse grounds, mud, and sand from the shallow sublittoral to depths around 100 m.
It is a nocturnal predator, targeting a range of molluscs and crustaceans, hiding buried in the substrate during the day.
