Some animals, like bait birds, are famous for their wonderful vision. But they are far from the only people you can jealous in this sense – other species also have a great visual device. Livescience.com information portal speakWhat animals have better vision.
This does not mean that any animal has the best vision, because the ideal image system does not exist. From the viewpoint of evolution, the development of advanced organs of vision is an extremely resource event, because the eye is a large part of the nervous system and requires a lot of energy. In order to control biological budgets, the evolution of animal promotion only develops the systems needed directly for the environment and their behavior.
For example, birds hunting, such as eagles, hawks and eagles, can be proud of the most detailed vision. They need to pay attention to potential production from a very long distance and for this purpose, birds have developed a point of view at extremely high resolution. The optics of prey birds provide an image higher than three or five times compared to human vision details. If a person can see the world through the eagle, they will feel like binoculars.
For such a vision, the bait birds have developed two adjustments. First of all, their eyes are much more proportional to the size of the body. They also have more clear cells – specialized cells feel light.
What about the brightest vision? Here, the championship belongs to the monitoring cancer-a bizarre spine, living in the shallow sea. They can see the color that a person cannot even imagine.
To understand how these creatures look at the world, you need to understand how the color vision works. People have three types of clear cells that act on awareness of red, blue and green. Many vertebrates have four types of cells – meaning a person with a worse color vision than many other species.
Meanwhile, Bogomol Crayfish can be proud to have up to 12 different types of inductance cells. Some of them, among other things, can distinguish between ultraviolet light, so that the world through the eyes of these shrimp can look completely different. In addition, they have receptors that feel the polarization of the typical feature of the light of light waves arising due to the dispersion of sunlight in the earth's atmosphere.
But science does not fully understand how the brain of Bogomol cancer processes all this information. It is likely that their visual system is honed to detect certain combinations of certain colors, not individual information.
Finally, the fastest vision is in insects. Although human vision is continuous, our eyes and brain can process information at limited speed. If a person sees a reality at a speed of about 60 frames per second, then the insect is likely to hundreds. For the context, in the eyes of insects, fluorescent lights, flashing notable even for humans, looking blinking. And a fly in the cinema can feel the movie on the big screen as a very fast presentation about the slides.
High -speed vision is only the reason why it is difficult to slap flies. She actually saw a person before a person performed any action. The bodies of these insects are so small that electrical signals need to go through a small distance between the eyes and the brain, so that they can handle the intuitive data much faster.
