A team of international experts, who arrived at the Egyptian resort of Sharm El-Sheikh after a few cases of shark attacks on humans, concluded that the coast, swim at least two predators that used to eat human flesh.
This opinion was voiced by experts after carefully studying the nature of the wounds on the bodies of the victims from shark tourists. According to them, the predator even belong to different species. If Russians and Ukrainians attacked korotkaia Mako, the deaths of German women over the weekend blame white tip reef shark. According to scientists, this is the worst scenario that they assumed, as one individual it would be much easier to catch.
While biologists believe that the Cougars, who were recently caught off the coast of the red sea, the people did not attack. It turns out that the shark-killers are still on the outside.
Meanwhile, scientists are trying to understand why fish that very rarely attack people, to change their behaviour. According to the expert from the United States, Director of the Florida program for shark research George Burgess, now the coast is examined in order to find any violations of ekosistemy the red sea.

Ten years ago, on the island of Sipadan in Malaysia, I took a picture of my first shark. It was almost certainly a shark-Zebra, Stegostoma fasciatum.
