The shark mako is a Espèce of Requin of the family of the Lamnidae.

Description

The shark mako or shark-mole blue is a Requin pertaining to the same family as the white sharks. It is of color blue harms on the top and white in lower part. Of very hydrodynamic form it has a maximum size of 4 meters. Its slits branchiale S are particularly broad.

Habitat

Pelagic tropical water and sometimes coastal and moderate. Evolve/move of surface to 740 meters of depth.

Reproduction

Ovovivipare with cannibalism will intra uterine. From 2 to 21 embryos measuring 60 cm with the birth. Gestation would last two years.

Food

Primarily pelagic Poisson S like the Tuna S but also of the Shark S as well as cephalopod S.

Characteristics

Power

This shark is able to maintain a temperature body higher of approximately 10°C than that of water, this characteristic coupled to its broad slits branchiales enables him to quickly reach high speeds and the ability to be able to make jumps out of water. Credited a speed of at least 45 km/h, certain authors advance that its top speed would be of about 100 km/h what would prove that this shark is able to make jumps of 10 meters out of water. Taking into account its food mode this speed enables him to drive out pelagic fish among fastest like the sailing or the Espadon. It can live 25 years.

Exploitation

It is one of the rare sharks whose meat is exploited in kitchen. It generally is sold output in slices. The flesh of this fish is firm (like meat) and resembles that of tuna, except the color which is a little clearer. Previously, the shark mako was marketed under the name of tuna of the Atlantic. Contrary to tuna, the shark-mole is a thin fish.

This shark is also particularly appreciated by the sporting fishermen taking into account his power and of its combativeness.

Danger to the man

The shark mako constitutes a potential danger for the man. Some not caused attacks blaming this species, including two fatal, are documented.

Conservation

Its long period of gestation and its late sexual maturity makes it particularly vulnerable to the overexploitation whose it is the object.

Other denominations

Shark mako with short fins. There exist four species of Requins moles: The shark mole salmon ( Lamna ditropis ); the shark mole commun run ( Lamna nasus ); the small shark mole ( Isurus paucus ).

The shark-mole blue belongs to the family of the Shark-mackerels, an small group of fast sharks divided into five species. Like its close relatives, the Large white shark and the Maraîche, the very particular adaptations of the shark-mole blue to its environment do one of super-predatory of the sea of it.
