Australian scientists have developed a new suits for divers. They repel sharks, though each in his own way, one of them makes a man invisible, and the other - makes the sharks think that the swimmer is poisonous. Interestingly, the costumes are designed on the principle of mimicry, the most popular pets in the world, patronizing and cautionary color.
The costumes, which are referred to Elude and Diverter researchers from the University of Western Australia have created in collaboration with designers from the company Shark Attack Mitigation Systems (SAMS). First - blue with blue graphic pattern: color-blind sharks, and blue color simply can not see. The second simulates the coloring of poisonous fish on which sharks prefer to stay away.
The creators of wetsuits, who have spent their development two years, claim that they can save the life of his master. Sharks have a keen sense of smell, but just before the attack, they rely primarily on their vision that they, too, is quite good.
This is what was the starting point for the creation of costumes. The combination of colors in Elude, according to representatives of SAMS, provides an optimum effect at various depths and distances. Although the shark and could smell the man in the water, but if she can not see it, it will dramatically reduce the probability of the sorry outcome for the diver.
As to the Diverter, then for him the designers chose a dark blue and white colors. The costume you can buy a set of stickers for the very surf to look even more ominous for the Sharks. Make a striped suit developers decided not to chance: long-term studies have shown that it strips most afraid of sharks. A contrasting colors only enhance the effect.
Most of the time spent on research scientists perception of sharks colors under water. Professor Shaun Collin and Nathan Hart used the techniques of molecular biology to the study of the genes responsible for coding the pigments in the retina of the eye shark.
The researchers set out to isolate the effect that some of the colors and shapes geometicheskie have on the sensory system of sharks, as well as find out what colors they see better and worse. Colleen and Hat modeled several light fields under water, to determine the ability of sharks to distinguish between colors, the brightness and track their reaktsiyu.Eksperimenty and helped scientists to create a pattern that for sharks will either invisible or intimidating, in contrast to the usual suit. Their development they checked in using a computer model, where virtual divers submerged at various depths to determine the optimal width of the bands and the intervals at which they should be located.
Many are afraid of poisonous animals fauna - that is, the production from which the threat that says: Do not eat me!, And this is reflected in the striped coloring, - says Colleen. - We use natural technology based on sharp contrast stripes. Diver will be clearly visible, and the shark realizes that as a food he did not suit her.
Hopefully, the suits will really help reduce the number of victims of marine predators in the past year, Western Australia was recorded five shark attacks on divers and surfers with a fatal outcome. Due to such excesses Australia has earned the reputation of the akuloopasnogo place in the world. According to preliminary data, the cost per gidrokstyuma be about $ 500.
