Isurus
The two living species are the common shortfin mako shark (I. oxyrinchus) and the rare longfin mako shark (I. paucus). They range in length from 2.5 to 4.5 m (8.2 to 14.8 ft), and have an approximate maximum weight of 680 kg (1,500 lb). They both have a distinctive blue-gray color scheme common among mackerel sharks.
Several extinct species are known from fossils found in sediments from the Cretaceous to the Quaternary (age range: 99.7 to 0.781 million years ago).[1]
The family Lamnidae also includes the great white shark and the porbeagle. Mako sharks are capable of swimming at speeds up to 32 km/h (20 mph).[3] The great white shark is also closely related to an ancient mako shark species, Isurus hastalis. However, fossil evidence suggests I. hastalis, like the great white shark, also belonged to the genus Carcharodon.[4]
