The biggest eyes in the world: who is the master?

Indeed, who owns the largesteyes in the world? The majority will start to guess: the whale, the sperm whale ... Not the most far-sighted will remember the elephant. But no, these giants do not own the "most-most" eyes. The largest eyes in the world have a giant squid, living mostly at great depths.

His organs of sight, having a diameter of up to twentyeight (!) centimeters, allow him to view from afar the danger in the semi-darkness of the ocean floor. To be afraid of this predator is whom. The largest of the toothed whales - sperm whales - are not averse to enjoying this sea predator. Opposing the squid, they can not do anything, so for him there is only one option for getting rid of the giant's teeth: escape by flight. And for this you must first notice the danger.

According to biologists, a giant squidthe depth of five hundred meters can be seen sperm whale at a distance of one hundred and twenty meters. The biggest eyes in the world could appear in an animal that lives in such conditions. For gloomy ocean depths, this is a fairly long distance, giving a chance to escape.

However, one would expect that the largestthe eyes in the world will be among the inhabitants of the half-darkness. Remember the animals that lead a nocturnal life. Those who are not equipped, like bats, with a natural "locator", will necessarily have eyes disproportionately large in size, which are better adapted for the night.

However, the question of the presence of proportionality orabsence thereof - the subject of an idle discussion. Nature itself is rational, and if animals have eyes, in our opinion, too large, it only means that they have become so in the process of evolution.

But the opponent of squid - sperm whale - in suchBig eyes do not need. In his evolution, another device was developed for detecting food at a great distance-the "sonar", about the same by the principle of action as in bats. It is interesting that in the dispute between a natural locator and large eyes, the locator wins. About three quarters of the sperm whale's diet is squid. Only complete fertility saves them from complete destruction.

The world's largest eyes proportionallybody size belongs to the Philippine turtles. With this record, the animal even got into the "Guinness Book of Records". This small animal (body length up to ten centimeters) is not difficult to guess, it leads the night way of life.

What are the biggest eyes in the world in man - is not known.

It is clear that representatives of the Mongoloid raceclaim the title of the owner of the biggest eyes can hardly. Some sites point to the American Kim Goodman, who through some manipulations gained the ability to roll his eyes by eleven (!) Millimeters. The spectacle is not pleasant. Others argue that the Ukrainian model, Masha Telna, has the biggest “natural” eyes. Is it really, or publication - only exercises greedy to the jaundice of journalists, is unknown.

Big eyes are not always beautiful and not alwaysa sign of health. For example, one of the symptoms of a thyroid gland disease (Grave disease) is “bulging” eyes. The disease is quite common. She suffered from time immemorial. For example, it is believed that the emperor Commodus, the last of the Antonin dynasty, was sick of her. This is indicated by his sculptural images. On the Commodus bust, the eyes have the appearance characteristic of a disease of the thyroid gland.
