Manhunt

Shark attacks on people are extremely rare. There are sharks whose size does not allow them to cause serious damage to humans. Such predators are not classified as traumatic. Tiger and white sharks are considered man-eating sharks. This does not mean that they hunt people, and a person is their daily diet. In general, when attacking a person, the animal does not realize that it is a person or another living being in front of it. Due to its size and disposition, the shark is the dominant predator of the seas and oceans. That is why, meeting people on her way, she tastes them. This predator feels great even in fresh waters.

Predatory instincts

The shark, like all predators, uses the effect of surprise and attacks suddenly, so it will not work to resist. Yes, and its size, and the strength of the jaw does not leave a chance.

People themselves share shark habitats: coastal waters, beaches. Surfers, fishermen, scuba divers often, without realizing it, provoke sharks. A shark is like a wolf in a forest: when you meet it, there is little chance of getting away alive. If a predator has reduced the distance and is in the visibility zone, this means one thing - he wanted to do it himself and will attack.

Many stories go around that dolphins came to the aid of people when they were attacked by a shark. Dolphins stay in packs, so they can resist the predator. Dolphins often fight sharks to protect their young.

Sharks have been living for many millions of years, and there are still many amazing mysteries about the life of these marine inhabitants to be revealed.
