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. 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.

Sharks: The story of a bookplate

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. The current was carrying us along sheer walls, and she, mysterious and beautiful, gleamed in the distance. My heart jumped to somewhere in the Adam’s Apple, I quickly raised the camera and took this blurry picture.

Shark-Zebra

The shark disappeared into the depths, and I got a new hobby — a passion for cartilaginous fish. Have devoted a considerably long time, wrote some articles , even led a couple of sections in Wikipedia. Traveled to different corners of the planet to dive with them.

Of all the sharks I liked Fox, or as she is known in English, thresher. She is like a shark-Zebra with long tail and harmless disposition. Graceful, smooth and swift. Without the aura of celebrity, without the reputation of a ruthless killer. So to speak, a humble toiler of the ocean depths.

About fish

Our planet is inhabited by almost 20 thousand species of fish. About 1/10 of them are commercial. They give people a lot of valuable products: food, medicines, fertilizers for the agriculture, pet food, industrial oils, raw materials for light industry.

To move in the water, have to spend a lot of energy. Nature took care of the fish, giving their bodies zaradougou streamlined shape. The speed of the fish (scombridae, tuna, sharks) in its form and speed resemble that of a torpedo. The fastest fish is considered fish-sailfish, swordfish and Marlin, which reach speeds of up to 130 km/ h. The rate of freshwater fishes is typically lower, but in critical moments of his life, in the moment of impending danger or in the event of an attack on their prey, they can take a short term shot at a speed of 1-2 km /h. Good speed swimmers usually are found in rivers with current (sabrefish, Chub, nase, Dace, salmon). The speed of the fishes living in stagnant water far below, but they are more nimble, nimble (carp, bream, Rudd). Continue reading
