Squid are found abundantly in certain areas, and provide large catches for fisheries. The body can be stuffed whole, cut into flat pieces, or sliced into rings. The arms, tentacles, and ink are also edible; in fact, the only parts not eaten are the beak and gladius . Squid is a good food source for zinc and manganese, and high in copper, selenium, vitamin B₁₂, and riboflavin.
