Many are touched by the sight of animals with big eyes. Indeed, such creatures seem amusing, unusual and beautiful. But which animals have big eyes and how does this help them in a harsh life?
Tarsier
Many have heard that there is a small animal that lives in the Philippines and is famous for its unusually large eyes. In his homeland, he received the name "tarsiers." Among mammals, he ranks first in terms of the ratio of eye and body size. Thanks to this, he was listed in the Guinness Book of Records. This small animal with big eyes has a body weight of only 134 grams. Females weigh even less - only 117 grams. Accordingly, they have a small body size, which usually ranges from 10 to 15 centimeters. But their eyes are surprisingly large, and each of them by weight exceeds the weight of the animal’s brain. If a person had the same growth-to-eye ratio, then it would look as if grapefruits were inserted in our sockets.
Tarsiers leads a night life. In the dark, he navigates very well, and he is also able to see ultraviolet light. But this crumb cannot distinguish colors. The animal is not dangerous to society, but rather eats various insects and worms. If someone manages to tame him, tarsiers will prove to be a good assistant to their master in the extermination of parasites. But this cute animal with big eyes with great difficulty gets used to a person and may not get along with him. So, spiders, small vertebrates, lizards, and insects are included in the diet of this eye. To eat, the baby grabs the victim with two legs and does not let go of it. It is interesting that tarsiers can rotate their neck 360 °, and this fact used to scare local residents who thought that the head of these animals was separated from the body.
Half Monkey Lory
There is another animal with big eyes (the photo is attached below), which causes tenderness in humans. These are half-loris monkeys who lead night life and are distinguished by good eyesight. In the daytime, these babies prefer to sleep, covering their eyes with their paws, but as soon as dusk sets in, they begin to run and play briskly with each other. If this animal hears the movement of an extraneous creature, it begins to move slowly or stops completely so as not to be noticed. If it was discovered, it is very difficult to tear it from the branch. Towards midnight, the loris begin to hunt for insects and birds. But they also love to enjoy the fruits that can be found on trees.
It is worth noting that these lemurs are recently turned on as pets. It should also be mentioned that this animal with large eyes can belong to one of three species: slow thick, thin and small thick loris are secreted. As a pet, they usually acquire the first appearance, since it is very difficult for others to take root in domestic conditions (they do not make contact and bite painfully).
Pets
Cats are the most common human pets. But they attract not only with their graceful, beautiful body, but also with big eyes. But even among cats there are champions - these are British. Compared to their bodies, their eyes are very large and they are not equipped with cilia. But this fact does not prevent the purrs from navigating in the dark. You can often notice how their eyes begin to glow in the darkness. Such a phenomenon is observed when light enters the cat's face, in which case it is reflected from the organ of vision exactly along the same path along which it hits the retina.
This pet with big eyes has a peculiar vision. The cat is able to see through 180 ° and observe what is happening behind her back, but at the same time she can not see the picture in front of her nose, so she is forced to connect the sense of touch. That is why cats are always on their guard. Interestingly, if necessary, the animal is able to focus its eyes on one point. At this moment, his muzzle seems very concentrated, and the pupils are completely dilated. In addition, it is important to note that the cat can see objects at a distance of 60 meters.
Also for many years it was believed that purrs see the world in black and white. But modern technology has proven that this is not so. Cats can distinguish colors, but this spectrum is not as wide as in humans. The main specificity of a cat's eye is the definition of gray shades. In any case, this animal’s vision is six times sharper than human. But this pet with big eyes can compete in its abilities with ostriches, which also occupy an honorable place in the list of "big-eyed".
Ostriches
This bird is well known to many inhabitants of the earth. It is ostriches that are considered the largest of the birds. The weight of an adult can reach 75 kilograms, and the height is up to 2.7 meters. Of course, ostriches are usually found a little smaller. But they are distinguished not only by their huge size, but also by their large eyes. For example, if you compare them with the brain of a bird, then its organs of vision are still much larger. Therefore, although the ostrich is not distinguished by a special intellect, it is famous for its sharp eyesight. These birds are able to view the object at a distance of a kilometer. As soon as the ostrich sees danger, he rushes to the bottom. Since other animals do not have such sharp eyesight, they watch ostriches and also rush to flee from danger, which they still do not even imagine.
Sea creatures
It is also worth talking about the biggest eyes of animals that live under water. These are octopuses, cuttlefish and squid. They need good vision in order to survive in total darkness, under the water. With a giant squid, each eye can have a width of almost 30 centimeters. Such sizes are really unusual for living things, but they are necessary to see objects at a depth of 2000 meters. In 2007, a squid was caught, whose eye reached almost 30 cm in diameter, and its lens was the size of an orange. It has been established that these creatures have the largest eyes on earth. It is worth noting that scientists have established an interesting fact: the captured animal was just a female teenager. It weighed 450 pounds, while adult squids can reach a mass of 750 kg.
Dragonfly
Another creature with large and unusual eyes is a dragonfly. Her organ of vision is more complicated than that of any other creatures. The eye of this insect consists of approximately 30, 000 facets. Thanks to them, the dragonfly is able to see simultaneously from behind, from the sides and in front of itself. So, she can immediately notice any danger or approach of food. In this case, the dragonfly distinguishes color and has the ability to see polarized light.
Gecko leaf-tailed
Another amazing animal with big eyes is the gecko. But besides the fact that his eyes in relation to the body are really large, they are still unusually arranged. This organ in an animal consists of dispersed pupils. They are divided into vertical and horizontal series. Thanks to this arrangement of the organ of vision, geckos see a color picture at night. Compare their vision with cat's. Purrs, as already mentioned, see in the dark about 6 times better than people. But geckos surpass our capabilities in this regard by 350 times!
Who else has big eyes?
On earth, there are many animals that can surprise with their appearance and large eyes. We examined those who surpassed the rest of the planet's inhabitants by these characteristics. We also learned the name of the animal with large eyes, which causes special tenderness in humans. But it should be noted that horses, dogs and many other animals that can move around quickly can be added to this list. Such animals always have larger eyes in relation to the body than other creatures. This is because at speed, the large eyeball helps to better recognize moving targets and calculate their speed.
