Mako shark description

There are many types of sharks in the world. Black-footed shark, tiger, Sakhalin, common gray shark - only about four hundred types. All sharks are similar, but completely different. What does a mako shark look like? The first thing to say: this is one of the largest, fastest and most dangerous predatory animals. Adult individuals of this species in length reach four meters, and weight gain more than half a ton. In the late seventies, the largest mako shark was caught, and this incident was documented. Its length was four and a half meters. Scientists suggest that this is not the size limit of the animal. The body of the shark is spindle-shaped and slender, the head is elongated, and the snout is oblong and pointed.Inward-curved teeth are long and sharp, the front ones come forward a little. Once in such a mouth, the chances of getting out of it are very, very small. The fins on the chest are narrow, and the dorsal fin (which first emerges from the water, giving out a shark) is wide, its tip is rounded, and the tip is sharp. The rest of the fins on the back and abdomen are very small. Herring sharks can be proud of their tail fin. The fins on the tail resemble the outlines of the crescent. Both blades - upper and lower - are quite large, almost equal in size (the lower one is slightly smaller). The eyes of a shark are medium in size, the back and sides are colored gray-blue. Hence the main name - the gray-blue shark mako. The animal is very flexible and beautiful. But with all its beauty, it is an aggressive predator.

Behavior and biological features

The mako shark is considered to be one of the fastest and most agile shark species, it can reach speeds of up to seventy-four kilometers per hour. She can easily jump out of the water into the air to a height of six meters, making a series of such jumps. A shark has the ability to quickly pick up speed while chasing a prey.At one of the experiments conducted, the animal was able to reach a speed of one hundred and ten kilometers per hour.

These sharks have a unique circulatory system. It is an interlacing of veins and arteries, which allows sharks to maintain body temperature higher than that of the environment (up to two degrees). Located such a network on the sides of the animal. It is possible to maintain heat and save it by warming up arterial blood due to venous blood. Venous is heated with muscle contractions - in motion.

Family and species of mako, reproduction

Mako sharks belong to the animal kingdom, their family is herring sharks. Genus and species - mako sharks. Sharks breed by egg production. Cubs, being in the mother's belly, grow in eggs, and sharks are born into the light, they are about seventy centimeters in length. The process starts from the end of winter to the second summer month; pregnancy lasts from fifteen months to one and a half years. One shark at a time can give birth to four to thirty babies. The number of offspring directly depends on the size of the mother shark. The maximum age was recorded in the female - at the time of her death she was thirty-two years old.

What and how does the mako shark feed?

The mako is based on fish. She prefers large bones, such as eels, sea urchins, eelpurs, sardines and other herring fish.Also, they do not deny themselves the pleasure to try plate-splay, and these are blue, gray, dark, short-haired sharks. In the mako diet there are cephalopods, squids, and sea turtles. Unlike the white sharks, the mako do not eat dead whales. Of marine mammals, they can attack a maximum dolphin, if size allows. Basically a dolphin can count sharks longer than three meters. They hunt mako closer to the surface of the water, sometimes they also get food at the bottom. Attack their victim from below, biting off a large piece of flesh. Sometimes they attack from behind, damaging the tail, which prevents the victim from moving and escaping. Mako is very sensitive to smells of blood and food. They are gaining tremendous speed in the direction of smell. When the food is already very close, the shark makes a strong leap or even a jump so that the prey does not have time to notice it. Sometimes a mako can injure a kinsman who hunted in these waters and spread the smell of blood. But when the shark realizes that it is not an object for food, it turns around and swims away.

Mako attacks on people

Mako is a large, aggressive shark. This species is dangerous to humans: there have been many cases of its attack. As many as forty-two mako attacks on humans were recorded over a thirty-year period.Three attacks ended very badly, the rest caused great harm to health, many people were disabled. But the shark does not consider a person as food - even having killed, the mako does not eat it. Most of the attacks were random: the shark attacked the man who caught her, injured the diver, mistaken for fish, and a swimmer in the hunting zone. It happens that a shark attacks a diver who has harpooned a fish in an attempt to take prey. As the divers, having met the mako, tell, the shark before the attack quickly swims the path of the eight, with its mouth wide open. Sharks rush to small boats, boats, bite them and even jump on board. These attacks are called provoked, because all the bitten boats are fishing. They simply smell the smell of fish and blood, and the mako, guided by the smell, attacks or jumps on board after the fish caught by the fisherman, after which the mako chased even in the water. There was not a single case where parts of the human body were found in a shark's stomach.

Also, mako is used as a target in sport fishing. This huge animal is caught by a harpoon, luring by pieces of fish and meat. To date, hunting for mako sharks is illegal. In 2010, this species was included in the Red Book, it was given the status of "vulnerable species".

For many years people tried to tame the mako shark, to populate this species for the economy in the pools. Many times tried to settle the mako in the aquarium, where the environment was close to the natural. But all these attempts were unsuccessful. The longest life in a mako shark aquarium is five days spent in New Jersey. They brought the animal there completely healthy. The shark began to beat against the walls, refused to eat. Subsequently weakened and died.A live mako shark can be seen off the coast of South Africa and the Maldives. Ecotourism is thriving here - diving under the water where sharks swim.
