How do you see the strangest eyes in the animal kingdom of the world?

The eye is one of nature's most complex structures, the product of millions of years of evolution. An organ that can instantly receive millions of different impressions and distinguish hundreds of millions of colors. The human eye with a resolution of 567 megapixels has the ability to detect the flame of matches from a distance of 80 km at night; However, we are not even among the top 10 living things on earth in terms of vision.

When you look at the world from a particular perspective for a lifetime, you soon forget that there are many other different types of vision. . In fact, different creatures have evolved to have the best vision in accordance with the living conditions.

you must have seen different forms of eyes in nature. For example, vegetarians, unlike us, have linear pupils that give them a panoramic view so that they can graze around while grazing. Or nocturnal predators who have the best night vision with a vertical pupil.

Although these are interesting in their own right, Mother Nature has trained far more sophisticated eyes that blow intelligence out of your head. eyes that can detect cancer before symptoms appear, multifaceted eyes that look up and down the water at the same time, or other things whose capabilities are beyond our comprehension. In the following, we will introduce some of the strangest eyes that seem to have emerged from the heart of Jules Verne and Asimov's stories. .jpg ">

Spidaj is one of the strange aquatic creatures that has a strange W shape apart from having 10 feet. Biologists have found that this structure of the eye helps the animal in enabling the underwater light field, but this is just the beginning.

It is cylindrical) and therefore should have a monochromatic vision, but their wide pupils have evolved in such a way that, like a prism, they decompose light and perceive colors in a different way. As a result, cephalopods are likely to be able to see colors we know nothing about.

Unlike other cephalopods, these animals' eyes can rotate around giving them a three-dimensional view. Scientists have found that this advantage gives them stereoscopic vision to highlight the nose, which helps them hunt more skillfully.

Small eyes and beads like birds are a world of wonders and allow them to see things that are not possible for us.

As we said we have 4 light receivers We have 3 color vision. Birds have six receptors, including four receptors for color vision, a cone receptor for low light vision, and a strange receptor for perceiving non-color motion.

Gives a magnetic field. How birds migrate so long with such precision was strange to everyone, but researchers have recently attributed this property to a special class of protein called cryptochrome that is sensitive to blue light.

A strange creature called the Anableps anableps actually has two eyes but evolved They are amazing. This fish lives near the surface of the water, and its favorite food is insects that live near the surface of the water. Another observes the water. Thus, while waiting to catch insects, the fish watches for invaders to attack from below.

Because the refractive index of light in air and water is different, the thickness of the lens and the corneal epithelium of each section are also different. To give the same view to the fish. Another interesting point is that the proteins in the light-receiving cells are different in each part, which makes the upper part sensitive to green light and the lower part to yellow light; As a result of this difference, the visibility of the fish is enhanced in the dark waters.

The strangest eye we know of in the realm of animals belongs to crustaceans hidden in deep-sea cliffs. Which has given them an extraordinary vision and they are able to see practically everything; So get rid of the clumsy idea of a mantis with a mantis shrimp. Recognize it. The eyes of this animal, which are placed on a pedestal, are able to rotate independently of each other and can distinguish depth with only one eye; An advantage that most living things, including us, do not enjoy.


BingMag.com <b>How</b> do <b>you</b> <b>see</b> the <b>strangest</b> <b>eyes</b> in the <b>animal</b> <b>kingdom</b> of the world? What are eyes made of? Well, the tissue itself is made up of cells. Of course, the story is different if we talk about a marine mollusk named Keaton. This relatively small creature that crawls on rocks and eats anything that gets caught protects it with strong armor.

The animal's eyes are made of a mineral called aragonite instead of living tissue. It is a kind of calcium carbonate. Simple ketone eyes are covered by the cornea and retina and can produce images, but what scientists are most interested in is How these images are processed by the not-so-advanced brain of this living thing. The evolutionary pathway is important because it resembles some of the earliest living things, such as trilobites, which also had mineral-colored eyes with a clastic lens. The long-extinct trilobites had the first fully developed eyes, so understanding their mechanism will provide a wealth of information about the evolution of the eyes and vision of living things.
