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'''.
 
 
 
==Anatomy and appearance==
 
With a full-grown length of 2.75 &ndash; 4&nbsp;m (9 &ndash; 13&nbsp;ft) it has been reported to weigh up to 800&nbsp;kg (1,750&nbsp;lb) 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 a better hydrodynamic shape than all other 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 makos{{Fact|date=February 2007}}.
 
 
 
==Naming==
 
The name "mako" comes from the [[Māori language]], but the [[etymology]] is unclear.<ref>{{cite web|url=http://www.maori.info/maori_language.htm|title=Maori language - a glossary of useful words from the language of the Maori New Zealand|accessdate=2006-08-11}}</ref> A typical [[Gloss (transliteration)|gloss]] given for "mako" is "large blue shark". The term entered the English language in [[1727]]. It can also mean "[[man-eater]]". <ref>{{cite web|url=http://www.etymonline.com/index.php?term=mako|title=Online Etymology Dictionary|accessdate=2006-08-11}}</ref>
 
 
 
==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.
 
 
 
==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 6&nbsp;m (20&nbsp;ft) 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 to 18 months.  Shortfin mako embryos in the female's body consume each other to get nutrients. This is called [[intrauterine cannibalism]].However the shark can only swim 48 km an hour sorry for lying. The fastest shark recorded speed was 49.8  km and hour sorry for more lying. Finally, the sharks cannot swim they float on water so it is another big lie. Sorry for the inconvenience the short fin shark is becoming extinct so do try to make it swim faster from the other fish or it will die.
