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

Indeed, who owns the biggest eyes 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 twenty-eight (!) Centimeters, allow him to view the danger from a distance 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 teeth of the giant: escape by flight. And for this you must first notice the danger.

According to biologists, a giant squid at a depth of five hundred meters can see a sperm whale at a distance of up to one hundred and twenty meters. The largest 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 biggest eyes in the world will be among the inhabitants of the semi-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 or lack thereof is the subject of an idle discussion. Nature itself is rational, and if animals have eyes, in our opinion, too large, it just means that they have become so in the process of evolution.

But the opponent of the squid - sperm whale - does not need such big eyes. In his evolution, another device was developed for detecting food at a great distance - "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, proportional to the size of the body, belong to the Philippine tartar. 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. Clearly, representatives of the Mongoloid race can hardly claim the title of the owner of the biggest eyes. Some sites point to the American Kim Goodman, who by some manipulation has the ability to roll his eyes out to eleven (!) Millimeters. The spectacle is not a pleasant one. Others argue that the biggest "natural" eyes are in the Ukrainian model of Masha Telna. Whether this is really the case, or the publication - only the exercises of the journalists, who are vile to the jaundice, is unknown.

Big eyes are not always beautiful and not always a sign of health. For example, one of the symptoms of thyroid disease (Graves' disease) is the bulging eyes. The disease is quite common. She suffered from time immemorial. For example, it is believed that Emperor Commodus, the last of the Antonin dynasty, was ill with her. His sculptural images speak of this. On the busts of Commodus, the eyes have a form characteristic of the thyroid gland.
