Sharks of the Mediterranean sea comprise about 47 species, 16 of them reach about three meters in length, and 15 species are considered potentially dangerous to humans. Among them are the white shark, considered the most dangerous of all. In other places, she usually eats everything what is on its way, but here she was acting towards people is very peaceful, preferring tuna.
Being an inland sea of the Atlantic ocean, the Mediterranean sea is distinguished by slow circulation of water masses and, consequently, slow the rate of exchange of waters of the Mediterranean sea with the Atlantic ocean, which makes a significant contribution to the maintenance of a constant temperature year-round. This circumstance creates ideal conditions for the existence of sharks. Continue reading
