Mako shark (Isurus glaucus)—Painting by Richard Ellis
Any of certain potentially dangerous sharks (genus Isurus) in the mackerel shark family (Isuridae). Two species are generally recognized: the Atlantic I. oxyrinchus and the Indo-Pacific I. glaucus. Makos range throughout tropical and temperate seas. Blue-gray, with a white belly, they are about 13 ft (4 m) long and weigh about 1,000 lbs (450 kg). They prey on fishes such as herring, mackerel, and swordfish. Outstanding game fish, they are prized for their fighting qualities and their spectacular repeated leaps out of the water.
