Each of us at least once in life thought of how animals see. And someone even dreamed to look on the world around at them with eyes.
For the person absolutely normally to see the world in three dimensions and sometimes it is difficult to it to assume how it is possible to look at it in a different way. And his animals absolutely in a different way, not boldly see. To approach a little their feelings make an experiment: close one eye and try to pour water in a glass. Most likely, it will not turn out from the first. Why does that happen? The answer is simple: having closed one, eyes you lose outlook, habitual for yourself, the brain cannot determine the required depth of a subject. Your eye sees in one plane, in accuracy as the sight of a large number of animals is arranged.
There is a category of animals which sight depends on arrangement of eyes and on a natural environment in which they live. For example, at a lizard, a pigeon and a horse of an eye are located in parallel each other, on both sides of the head. Therefore, to see in three dimensions as the person they cannot. It is possible to refer to our sight, for example, cats and monkeys closer, their eyes are located on a front part of the head and the world for them relief too.Let's address biology: each eye sees a subject under a different corner, and the general picture develops by stratification, for definition of this type of sight terms "binocular" or "three-dimensional" sight were thought up. Thus the relief is also created. As it was already told above, the arrangement of eyes directly depends on a way of life and the habitat of an animal. For example, the horse which sight is not relief is capable to see what occurs sideways or behind without turning the head. That is, actually she sees without changing a pose much more. It is connected with her way of life, eating a grass, for it there is no need to estimate surrounding distance with the maximum accuracy. How do the animals belonging to a species of predators see? The hunter needs to define distance to the victim with the maximum accuracy correctly to calculate a jump. Therefore his sight binocular. The nature put bigger quantity of herbivorous mammals, than predatory therefore the binocular sight meets in fauna rather seldom. Birds of prey got the most sharp-sighted sight, even in spite of the fact that their eyes are in parallel each other. But there is the feature — their form. Unlike animals their eyeball a little convex. Therefore the bird sees everything that occurs both in front, and sideways. Scientists claim that the majority of animals do not distinguish color, and the bee, for example, is capable to see the color which is not distinguished by a human eye. Do not distinguish color of a dog, a cat, raccoons, hares, polecats and bulls that the myth that the last are infuriated by a red rag pulls down. Not bad distinguish colors of a lizard, a turtle, a monkey and bears. There is an opinion that if the subject is brightly painted, then any animal will distinguish it among others, not for nothing the nature allocated many animals with a peculiar color.
