Sharks-cannibals: causes of attacks and geography of habitat. Which sharks most often attack people?

Every year, new ones become known in the world.cases of shark attacks on people. Impassive statistics states that for the most part these clashes threaten a person with shock and bite marks that will remind you of a terrible meeting for a long time. But if the attacking enemy is a large shark, then such a fight may be the last in the life of an unlucky person who has encroached on its hunting grounds.

Today we will talk about why sharks attack people inhabited by especially dangerous species of these fish and how you can avoid the fatal collision with strong and cunning inhabitants of the deep sea.

Is a meeting with a shark always a risk of being eaten?

It is estimated that the risk of being attackedman’s sea predator is very small - one to 11.5 million. The chance to die from such an attack is even less - one to 264.5 million (by the way, about 3000 people drown in the United States each year, and one dies from sharks). By the way, pay attention to a remarkable fact: every year people kill 100 million of these amazing creatures!

In the world there are more than 360 species of sharks.But, contrary to established ideas, only a few of them are truly dangerous to humans. This is a white, tiger, long-winged gray and stupid shark. They were the ones who were noticed in unprovoked attacks on people who caused death.

Today you can see what a man-eating shark looks like when looking at the photos posted in this article.

Meet the eater shark

With representatives of the shark world, consideredcannibals worth a closer look. The main of them is the great white shark. She is incredibly voracious and absolutely omnivorous. In the stomach of the caught representatives of this species, they found turtles, lobsters, pieces of ship's tackle, and crates, not to mention the remains of people and animals. Although, of course, the white shark prefers high-calorie meat of seals or fur seals.

Photo of a man-eating shark posted here, for surecan convince the reader of how powerful and amazingly powerful this fish is. On average, it grows to 5-5.5 m in length. This is the largest predatory fish on earth. In addition, she is very curious and shows ingenuity and sociability, if there is a need. Among researchers, it is believed that unfamiliar objects of these sharks often bite out of cognitive goals - to determine how edible they are.

By the way, this terrible predator is on the verge of extinction. In the world now there are approximately 3,500 individuals of this species.

Features of shark digestion

There are legends about the insatiability of sharks.Their wombs can even digest bolts and nuts! A similar phenomenon is explained by the amount of hydrochloric acid in sharks gastric juice. And if something completely inedible comes across to the omnivorous predator, it makes a purge: it turns the stomach around and belches the food.

Интересно, что желудок акулы – это не только processing plant, but also a warehouse of food supplies on the "black" day. Predator digests eaten in a special spiral valve, which is an outgrowth on the mucous membrane of the digestive tract.

If the shark is full, then she swallowedmay leave in the stomach until it feels hungry. Then the piece is sent to the intestine, where it enters the spiral valve and is digested.

Are there man-eating sharks in the Black Sea?

Of course, vacationers accustomed to spend holidayson the Black Sea, I wonder if it is possible to meet cannibal sharks there? Answering this question, it should immediately be noted that low salinity impedes large sharks to settle there. It is possible that tireless pilgrims swim there through the straits from the waters of the Mediterranean Sea, but they do not float further than the Bosphorus and the Turkish shores - the water is not the same.

Еще одной веской причиной отсутствия интереса к Black Sea waters of the described sharks are too scarce in their understanding of food supply. In this sea there is a very thin layer of water suitable for life, and its few inhabitants cannot saturate large ever hungry predators. And the temperature in winter does not give chances to heat-loving fish to feel comfortable at all.

Although, of course, the sharks in the Black Sea live, thoughnot terrible cannibals, who are afraid all over the world, but much less dangerous: a quark shark and a cat shark. The first one sometimes bites a person, but this happens only for protection purposes.

The most dangerous places on the planet

Первое же место по количеству акул, нападающих на people probably occupy the coastal waters of Australia, North America and Africa. Here toothy predators make regular attempts to try human flesh. True, it cannot be argued that they are especially frequent. According to statistics, this is not more than three people per year (note that many more people die from the thunderbolt).

The fact is that the main habitat of these creatures is water, where the depth is not less than 300 m. Shallow waters are visited very rarely and, as a rule, quite by accident.

Maybe the attack is provoked by people?

At the time, man-eating sharks made a lot of noisecoast of the Sinai Peninsula. The cozy resort town of Sharm el-Sheikh on the Red Sea turned out to be unsafe for tourists who love snorkeling and water recreation. However, in this case, the rest were themselves to blame. They frivolously fed the predators, throwing food from the sides of tourist boats and yachts and completely forgetting that a shark doesn’t matter that swims on the bread territory that has become such - a piece of fish or a whole person.

The waters of the Atlantic are no less dangerous.ocean, washing the coast of Brazil. Here, on the outskirts of São Paulo, there are many slaughterhouses, the blood of which was drained for a long time right into the ocean. You understand that such a “cocktail” could not help but attract to the shores a huge number of sharks, which, ohalev, attacked people. Only after the city authorities have taken appropriate measures, cannibal sharks here they reduced their appetite.

How do sharks hunt

Sharks have almost no enemies, they headfood pyramid. For their endless search for food, the ever-hungry predators are perfectly adapted. More recently, it was found exactly how they hunt.

Initially, the victim is discovered through change.pressure or vibration that occurs during its movement in the water. The shark is able to catch these vibrations at a distance of up to 180 m with the help of nerve endings. And as soon as the said call to dine is heard, the predator uses its sense of smell. And she is truly incredible! The shark can smell 10 g of blood dissolved in millions of liters of water. This "lighthouse" attracts her as the most powerful drug. And at a distance of 15 m the queen of the seas is already capable of seeing her victim.

The shark is nearsighted and sees movement rather thanoutlines of objects. Having approached on 3 m, the predator is accepted to circle carefully around the victim. Sometimes, having made a couple of detours, she loses interest and retracts back home, and sometimes rushes to attack. By the way, this moment in her behavior has not yet been studied.

How do sharks treat blood

It was already mentioned above that the blood that fell into the water is a sure way to attract sharks. Sensing her, these insatiable wombs lose their heads, and nothing can stop them.

And the so-called man-eating sharks, and nottheir relatives, suspected of this, having stupefied with blood, rush on everything that moves. Their bodies with powerful blows to the water turn it into a bloody foam, and if one of the brethren turns out to be unintentionally bitten or wounded in this dump, then it will immediately be torn to shreds.

How to avoid the attack of a killer shark

Поведение акулы непредсказуемо.She can swim indifferently for a long time nearby, and then suddenly attack a swimmer. Such an attack can be research (after all, the shark in no other way can satisfy its curiosity towards an unknown object), and the desire to have lunch. To date, there is still no way to completely protect yourself from being attacked by a predator in the water, but some precautions can still be taken.

• Try not to be in the water at dawn, at dusk or at night. At this time, the sharks are particularly actively looking for a delicious food to the table.
• Avoid places where they can be found more likely. The steep angle of the seabed and dark water should alert you!
• If you are injured and the wound is bleeding, then immediately try to get out of the water. After all, we all know the phenomenal subtle flair for blood that cannibal sharks have.
• Clearly follow all instructions rescuers.

And most importantly - do not lose common sense!After all, even those sharks that are considered safe are wild animals, so no one can predict how they will behave. Be careful and prudent!
