The Atlantic halibut, found on both sides of the North Atlantic Ocean, is the largest flatfish; it may reach a length of about 7 ft (2 m) and a weight of 720 lb (325 kg). It is brown, blackish, or deep green on the eyed side. The smaller and slimmer Pacific halibut is found on both sides of the North Pacific Ocean. Other edible halibut include the Greenland halibut, of Arctic and near-Arctic parts of the Atlantic, and the California halibut (family Bothidae), found along the California coast.
