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.
Anatomy and appearance
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 sharksTemplate:Fact."Oh get fucked off with or I'll wrap it round your bastard neck in a minute! Oh fucking hel!!"
Naming
Template:Disputed-section The name 'mako' comes from the Māori language for blue lightning, reflecting its color and speed.[citation needed]
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 watersTemplate: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 46 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 worldwide.
Reproduction
The shortfin mako shark is a yolk-sac 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.
