Animal Eye

Almost all animals found in nature have eyes. Most of the eyes of some animals were placed inside the skull, but a small part remained outside. The bones around the eye form a protection shield against impacts from all angles. Birds, insects and sea creatures in the environment to protect the eyes and the most comfortable and most necessary way to see the features have been provided.

In this article we will explain with examples, you will witness the eyes of many animals equipped with interesting skills from each other.

INSECTS

The leaping spider, like most spiders, goes to the prey itself, instead of networking and waiting for its prey. Therefore, the spider's visual system is very complex. Evaluating information from an area of 300 degrees is extremely difficult, even for the human brain. This tiny spider has an eye structure that can look, perceive and evaluate in different directions.

Eyes of insects are quite different from human eyes. There are two kinds of eye structures in these creatures, simple and complex. Simple eyes are small and round. They can only distinguish between light and darkness. Honeycomb eyes are both more complex and larger. These eyes consist of hundreds of small particles. In fact, every piece is like an eye. Because each has its own special lens and light-sensitive cells attached to the brain.

SEA WORLD

Octopus has one of the most complex eye structures among invertebrates. The octopus eye also operates on the basis of the camera principle. But the image taken by the receiver is smaller because the eye itself is smaller. Each of the receiving cells sends signals directly to the brain, which connects with thousands of others to form a single cable, such as the optic nerve. Through this cable the signals reach the optical lobes. The octopus sees very clearly thanks to its highly complex eye and the superior structure of the central nervous system.

The creatures of the underwater world are quite different from those living on land. Because the underwater world is almost like another planet and the owners of this world have been created in the most ideal way according to their environment.

 

The eyes of the fish look at the world through a transparent cover. This curtain resembles divers' underwater goggles. The spherical and rigid lens structures are arranged to see objects in close-up. The lens in the fish eye produces a clear image by refracting the light more than the flat eye lens in human and land animals. Fish can see multiple images at the same time.

BIRDS

The most important sense for a flying creature is vision. Because flying, which is a miracle in itself, will be extremely dangerous unless it is supported by superior vision. Therefore, God has given birds superior vision as well as their ability to fly.

 

An owl has an 80-degree field of view, but can move its head up to 270 degrees depending on its species. Thus, the owl can quickly see its entire circumference by turning its head about three quarters of the circle. The night vision of the owl is 50 times sharper and clearer than that of humans.

SNAKES

Most snakes have eyes on both sides of their heads. Therefore, each one sees different images. Eyes on both sides of the head does not prevent the sight of the front. The snake, which sees both the front, the rear and the top, thus dominates an extremely wide viewing angle.

 

Some types of snakes see rays of a higher wavelength than humans. These rays, called infrared, can only be perceived by man as heat. Snakes have eyes that perceive infrared rays as images. They are one hundred thousand times more sensitive to infrared rays than human skin. In this way, the smallest temperature difference is immediately felt.

REPTILES

Many reptiles can see colors. Thanks to this feature, even artfully camouflaged insects can be distinguished and provide a great advantage for hunting.

 

Chameleons feed on insects. Hunting tactics are extremely interesting. Each of his eyes can turn in any direction independent of the other. Two different images occur in the brain. In this way, he approaches his prey in an extraordinary slowness and follows his prey with one eye, and watches the environment with his other eye. When he gets close to his prey, he focuses his two eyes on his prey to pinpoint the exact position of his prey and catches it with his tongue.
