10 animals with enormous eyes

Vision - the most important sense for many animals, including humans. Take a look at some of the strangest and most incredible eyes in the animal kingdom.

Tarsier

This is a small nocturnal primate that lives in the tropical forests of Southeast Asia. This is the only carnivorous primate in the world, it feeds on lizards, insects and even birds. But its most interesting feature is the huge eyes, a disproportionately large in relation to the whole body. If these proportions apply to the man, his eyes should be the size of a grapefruit. Tarsiers have very keen eyesight. Even suggest that they can see ultraviolet light. On the other hand, tarsiers bad distinguish colors, as well as many other nocturnal predators.

Chameleon

Chameleons are known for their ability to change color, which helps them to communicate and express their intentions or mood (only a few species of chameleons used as a camouflage color change). These lizards are also very unusual eyes. Eyelids completely connected, there is only a small crack for the pupil. Each eye moves independently of the other, allowing you to watch a chameleon for prey and possible threat at the same time.

Dragonfly

dragonfly eyes are so big that cover almost the entire head, making her look like a helmet and giving the field of vision of 360 degrees. These eyes are composed of 30 000 parts, each of which includes a lens and multiple photosensitive cells. Eyesight dragonflies excellent. They can define the colors and polarized light, and dragonflies are particularly sensitive to movements.

Listohvosty gecko

Listohvosty gecko has a very unusual eyes. It has vertical pupils, in which there are a few "holes". These holes extend at night, allowing these lizards to see better. gecko eyes contain much more light-sensitive cells than the human eye, allowing the animal to detect objects and even distinguish colors at night. While cats and sharks are seen at 6 and 10 times better than humans, geckos - 350 times better.

Colossal Squid

This is the largest invertebrate known to science. This squid is also the largest eyes in the animal kingdom. Each eye may be up to 30 cm in width. Such big eyes allow the squid to see in the dim light, which is very useful for an animal that spends most of his time hunting at a depth of 2,000 meters under water.

four-eyed fish

These fish are found in Mexico and Central America. They are very small, up to 32 cm long, feed on insects, so most of the time near the water's surface. Despite their name, these fish are only 2 eyes. However, these eyes streaked divided and each half has a pupil. This strange adaptation allows four-eyed fish is good to see both above and under water.

stylommatophora flies

These are small, but the unusual creation inhabit the jungles of Southeast Asia and Africa. Name one time they got out of the long protrusions on both sides of the head with the eyes and antennae on the end. Males are longer stems. According to observations of females prefer males with longer stems.

Opistoprokt

Opistoprokt - deep-water fish from one of the most bizarre eye structures. A characteristic feature opistoprokta eyes are cylindrical upward.

Spider-ogre

Spiders are known to many eyes. In Spider-ogre of 6, but it looks like 2, as the average pair of eyes is greatly increased. All this serves to improve night vision. Spiders, ogres excellent night vision, not only because of the size of the eye, but also a large number of light-sensitive lenses, covering them. This membrane is so sensitive, that is destroyed every morning and night grows.

cancer-mantis

These cancers are known for their aggressive and kind of weapon (they have a very sharp and powerful claw that could easily be cut in half human finger and knock out the glass in the aquarium). Mantis shrimp have the most complex eyes in the animal kingdom. They distinguish 12 basic colors - four times more than men, as well as different kinds of light polarization, that is, the direction of the light wave vibrations. eye photosensitive cell are rotated relative to the light polarization plane sensing substantially all of the visible spectrum - from ultraviolet to infrared boundaries. Now we can only guess how the world looks to this crustacean.
