Isurus oxyrinchus

Shortfin Mako (Isurus oxyrinchus)

Where found: The shortfin mako inhabits offshore temperate and tropical seas worldwide. The closely related longfin mako shark, Isurus paucus, is found in the Gulf Stream or warmer offshore waters.

Description: The 'Shortfin Mako Shark (Isurus oxyrinchus—meaning "sharp nose") is a large mackerel shark. It is commonly referred to as the mako shark together with the longfin mako shark (Isurus paucus). The Shortfin Mako is a fairly large species of shark. An average adult specimen will measure around 3.2 meters in length and weigh from 60-135 kg. Females are larger than males. The largest "mako" taken (not verified between the two species) on hook-and-line was 505.8 kg. The Shortfin Mako is cylindrical in shape, with a vertically-elongated tail that assists its highly hydrodynamic lifestyle. The Mako is in fact the fastest shark of all. This species' color is brilliant metallic blue dorsally and white ventrally, although coloration varies as the shark ages and increases in size. The line of demarcation between blue and white on the body is distinct. The underside of the snout and the area around the mouth are white. Larger specimens tend to possess darker color that extends onto parts of the body that are white in smaller individuals. The juvenile mako differs in that it has a clear blackish stain on the tip of the snout. The Longfin mako shark very much resembles the Shortfin, but has larger pectoral fins, dark rather than pale coloration around the mouth and larger eyes. The presence of only one lateral keel on the tail and the lack of lateral cusps on the teeth distinguish the makos from the closely related porbeagle sharks of the genus Lamna. Mako surprises diver

-The '''shortfin mako shark''' (''Isurus oxyrinchus'' "sharp nose") large [[shark]] of the [[Lamnidae]] family. Along with the closely related [[longfin mako]], ''Isurus paucus'', it is commonly called just '''mako shark'''.

+The Shortfin Mako is a fairly large species of shark. An average adult specimen will measure around 3.2 meters in length and weigh from 60-135 kg. Females are larger than males. The largest "mako" taken (not verified between the two species) on hook-and-line was 505.8 kg.
-==Anatomy and appearance==
+<!--T:3-->
-With a full-grown length of 9 - 13 ft (2.75 - 4 m) it has been reported to weigh up to 1,750 pounds (800 kg) and has a bluish back and white underside. Although the sexes grow at about the same rate, females are thought to have a  longer [[life span]], and grow larger and weigh more than the males.  Shortfin makos are renowned for their speed and their ability to leap out of the water. Mako sharks have the most perfect hydrodynamic shape of all sharks,and this, combined with the lamnidae's typical high aerobic muscle mass, reflects in the spectacular speed and agility of both the longfin and shortfin sharks{{fact}}.

-==Naming==
+<!--T:4-->
-The name 'mako' comes from the [[Māori language]] for ''blue lightning'', reflecting its colour and speed.
+|range=
+The shortfin mako inhabits offshore temperate and tropical seas worldwide. The closely related longfin mako shark, ''Isurus paucus'', is found in the Gulf Stream or warmer offshore waters.
-==Distribution==
+}}
-The shortfin mako is found in [[temperate]] and [[tropical]] seas worldwide. Some of the largest makos in the world can be found in [[New England]] waters{{fact}}.  The closely related [[longfin mako shark]], ''Isurus paucus'', is found in the [[Gulf Stream]] or warmer offshore waters.

-==Behavior==
-The shortfin mako's speed has been recorded at over 22 miles (35 kilometres) per hour but has been reported to swim as fast as 60 miles per hour. Shortfin makos can jump up to 20 feet in the air.  Due to its speed and agility, this high leaping fish is sought as [[Game (food)|game]] worldwide.
-==Reproduction==
-The shortfin mako shark is a yolk-sac [[Ovoviviparity|ovoviviparous]] shark, meaning it gives birth to live young who feed from a sac full of yolk in the womb. The gestation period for a mako shark is 15 - 18 months.  Shortfin mako embryos in the female's body actually consume each other to get nutrients. This is called intrauterine cannibalism.
