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

<!--T:2-->
 +
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''.

==Distribution==

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

−
Shortfin mako sharks live in tropical and temperate offshore waters. They are a pelagic species that occur from the surface down to depths of 150 meters (490 feet). This shark is seldom found in waters colder than 16 degrees Celsius.
 
−
 
 
−
The shortfin mako is found worldwide. In the western Atlantic it can be found from Argentina and the Gulf of Mexico to Browns Bank off of Nova Scotia. In Canadian waters these sharks are not abundant as they prefer warm waters, but neither are they rare. Shortfin makos are often found in the same waters as swordfish as they are a source of food and both fish prefer similar environmental conditions.

==Behavior==

The shortfin mako's speed has been recorded at 50&nbsp;km/h (31&nbsp;mph) and there are reports that it can achieve bursts of up to 74&nbsp;km/h (46&nbsp;mph).<ref>{{cite web|url=http://www.elasmo-research.org/education/shark_profiles/i_oxyrinchus.htm|title=Biology of the Shortfin Mako|publisher=ReefQuest Centre for Shark Research|accessdate=2006-08-12|author=R. Aidan Martin}}</ref> Shortfin makos can jump up to 9&nbsp;m (28&nbsp;ft) in the air. Due to its speed and agility, this high-leaping fish is sought as [[Game (food)|game]] worldwide.  This shark is highly migratory. They are also one of four warm-blooded sharks which helps them in their speed.

There is still some uncertainty about its life-span, but it is suspected to reach ages of between 11-23 years.

−
==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 to 18 months.  Shortfin mako embryos in the female's body consume each other to get nutrients. This is called [[intrauterine cannibalism]].
 
−
 
 
−
Female shortfin makos usually become sexually mature at a length of 3 meters. Developing embryos feed on unfertilized eggs in the uterus during the gestation period of 15-18 months. The 4-18 surviving young are born live in the late winter and early spring at a length of about 70 cm, but have no placental connection during development (ovoviviparity). It is believed that females may rest for 18 months after birth before the next batch of eggs are fertilized.They eat james langes vaggina ans gets a orgasim from it.

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
