The common short-fin mako shark (I. oxyrinchus) and the uncommon long-fin mako shark
are the two species that are still alive today (I. paucus).
They have a maximum weight of around 680 kg and a length of
2.5 to 4.5 m (8.2 to 14.8 ft) (1,500 lb).
They both have the striking blue-gray coloring that mackerel sharks are known for.
From fossils discovered in layers dating from the Cretaceous to the Quaternary,
we know about a number of extinct animals (age range: 99.7 to 0.781 million years ago).
The great white shark and the porbeagle are both members of the Lamnidae family.
The maximum swimming speed of a mako shark is 32 km/h (20 mph).
