Man-eating sharks are operating in tandem

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.
