According to some of the oldest interpretations, the eye is first; It consists of a kind of tissue pit covered with light receptors, or a simple light-sensing region that scientists call the eye spot. Of course, over time this primitive structure of the eye has changed. Lenses that bend and focus light, corneas have evolved. Especially for land-dwelling organisms, the eye gained special importance.
The structure of the eye has also changed according to the vital needs of living things. For example, British biologist Michael Land, in a study he conducted in 2005, said, “In the fish, the cornea, which is only a transparent protective covering for the eye, has become an image-forming structure on its own. He mentioned that the fish develop an eye structure suitable for both air and water conditions. Despite this, there are still life forms, such as flatworms and mollusks, that preserve their basic structures and are content with simple eye sockets.
Here are some unusual and beautiful eyes from the animal kingdom that we might wish to have!
(Contains disturbing images for those who cannot look at creatures such as reptiles and spiders!)
Mossy New Caledonian Gekko
The largest lizard species ever recorded, the Mossy New Caledonian Gekko’s eyes can grow up to 14 inches, or about 36 centimeters, when needed. He also has the unusual feature of cleaning his eyes with his tongue.
Great Fin Squid
I wish I had eyes like that. The big-finned squid, which has silvery eyes, probably has two structures surrounding its eyes. One is cells filled with tiny light-reflecting plates, and the other is tiny, pigmented organs that cephalopods can selectively contract and relax.
Atlantic Nurse Shark
Known as the Atlantic nurse, the shark’s eyes are not as developed as its other senses and do not have as good vision as expected. The fact that it can close its eyes while sleeping and stay still is a feature that distinguishes it from other shark breeds.
Coral Boring Clam
This mollusk creature, called the coral boring clam, has 11 eyes. Eyepieces cannot focus light, as most animals do. Instead, it uses reflective crystals, also found in carp scales and chameleon skin, to collect and direct rays.
Gray Whale
In most marine mammals, including these so-called gray whales, as they return to the surface after diving, their pupils constrict to a bean-shaped crescent in the lower part of the eye and then a pale crescent connecting the two small holes, as they try to cope with the changing light intensity.
Parrot
Even though the rays in the ultraviolet range, also called violet and beyond, are outside the limits of human eyes, parrots can see UV rays, which play an effective role in their mating and foraging habits.
Four Eyed Fish
While the four-eyed fish is supposed to have four eyes, it apparently only has two eyes. But each eye has two different lobes. These lobes, one above and one below the waterline, are a physical advantage of the four-eyed fish for reaching nutrients both above and below.
Wood Lice Spider
This species, called the woodlice spider, has six eyes instead of eight, which is relatively rare in spiders. Most do not have the main eye, which has the ability to see color and see far more precisely.
Indian Elephant
Indian elephant eyes have a negative trait that some people also have: color blindness. Indian elephants, which have red and green color blindness, are very similar to the human eye in terms of structure and appearance.
cattle fly
The eyes of these creatures, which are called cattle flies, are attracted to polarized light and light rays that vibrate in the same direction, thus realizing the phenomenon of ‘seeing’. Females, on the other hand, have the ability to find their prey by locking in the polarized rays emanating from their hair.
Crocodile Fish
Crocodile fish hunt by lurking on sandy ocean floors. Therefore, their eyes have lace-like structures that hide their pupils and support their camouflage and serve as lids.
