Common Lobster Homarus gammarus
In life, the upper surface of the common lobster is blue mottled with yellow, while its underside is more yellowish. Individuals weigh up to 11 lb (5 kg). The common lobster has large, differently sized claws: the smaller one has sharper edges and is used for cutting prey, while the larger one is used for crushing. It lives in holes and crevices on the sea bed. The common lobster is commercially important and in danger of overexploitation because it matures slowly, not beginning to breed until it is about six years old.
