Does the shark is dangerous?

The hype and disaster movies have given to sharks the image of dangerous predators that pounce on anything that swims, including swimmers - which is far from the case.
In fact, sharks rarely attack human, a hundred cases or less are reported each year. Half the time, the man survived the encounter.
However, this is increasing. Mainly because divers, swimmers, surfers and other water skiers ventured deeper and deeper into areas where previously sharks reigned as kings.
There are approximately 370 species of sharks, including thirty species dangerous to humans. Among them, the great white shark, which is up to 8 meters long and 5 tons. But the largest species, the whale shark and basking shark, are harmless, even if their 15 meters long make of them giants impressive.
Respect of a number of basic rules will minimize the risk of being attacked: Do not swim alone or swim at night. And for women, avoid diving while menstruating because the smell of blood can attract sharks by far. People should also avoid wearing jewelry and bright color swimwear that can reflect light and make the shark believes that it is a fish. In general, it must be remembered that the eyes of sharks perceives particularly contrasts. Finally, avoid violent movements, that could make the shark believe that this is an easy target - a fish in distress, for example.
In addition, a device was recently developed that protects the men surrounding an electric field extremely low. Too small to be seen by man, it is powerful enough to ward off the shark, sensitive to the slightest shock.

    Five rules to stay safe:
  • Swimmers are usually solitary attacked the groups. Dive more.
  • The shark can become very aggressive. Do not swim in areas where fishermen have cast bait.
  • The smell of blood attracts sharks. Do not swim with open wounds or during menstruation.
  • Avoid areas where the ocean floor drops abruptly. Sharks like to congregate in these places.
  • Avoid colors or jewelry that reflect light so that the shark does not confuse the swimmer with a fish.
