The Brown Crab is also known as the Edible Crab and is better known for us as the North Sea Crab. In French this crab is called 'Tourteaux' and is found in the waters of the North Atlantic. Large concentrations can be found in British waters to a depth of 300m. Brown Crab is an arthropod. This means that the legs are connected directly to the head. His shield, also known as Carapax, can achieve a width of 25cm with a weight of 3 kg. The Brown Crab has 10 legs with the meat in the two front legs. Brown Crab is often traded alive, but it is difficult for consumers to keep it alive.
