Isurus is a genus of mackerel sharks in the family Lamnidae, commonly known as the mako sharks. There are two living species, the common shortfin mako shark (Isurus oxyrinchus) and the rare longfin mako shark (Isurus paucus), and several extinct species known from fossils. They range in length from 2.5 to 4.5 meters (9 to 15 feet), and have an approximate maximum weight of 800 kg (1,750 lb).
