Many are touched at the sight of the animals with big eyes.Indeed, these creatures seem amusing, unusual and beautiful.But some animals big eyes and how it helps them in the harsh life?
Tarsier
Many have heard that there is a small animal that lives in the Philippines and is known for an unusually large eyes.At home, he was named "tarsier".Among the mammals, it is the first place in the ratio of the size of the eyes and body.Because of this he was listed in the Guinness Book of Records.It is a small animal with big eyes has a weight of 134 grams.Females weigh even less - only 117 grams.Accordingly, they have a small size of the calf, which normally ranges from 10 to 15 centimeters.But their eyes are remarkably large, and each weight exceeds the weight of the brain of the animal.If a person had the same ratio of "growth-eye", it would seem as if in orbit we inserted grapefruit.
Tarsier is the nightlife.In the darkness, he focuses very well, and he is able to see ultraviolet light.But to distinguish colors that pipsqueak can not.The animal is not dangerous for the society, but rather eat a variety of insects and worms.If someone will be able to tame it, the tarsier would be a good assistant to his master to exterminate vermin.But this cute animal with large eyes with great difficulty getting used to humans and can not get along with him.Thus, in the diet of the Scout includes spiders, small vertebrates, lizards and insects.To eat, enough crumb sacrificed two legs and not letting go of her.Interestingly, the tarsiers can turn his neck at 360 °, and this fact very early scare the locals, who thought that the head of these animals is separated from the body.
prosimians Lori
There is another animal with big eyes (photo attached below), which causes tenderness in humans.It prosimians Laurie, who lead the nightlife and distinguished good eyesight.During the day, these kids prefer to sleep, covering his eyes legs, but as soon as twilight, they start to run and lively play with each other.If the animal will hear the motion being an outsider, he begins to move slowly or not at all stops not to be noticed.If it was nevertheless found, remove it from the branches is very difficult.Close to midnight Laurie begin to hunt for insects and birds.But they also love to eat the fruits that can be found on the trees.
worth noting that these lemurs recently the plant as pets.You also need to mention that this animal with big eyes may belong to one of three types: the slow release of thick, thin and small slow loris.As a pet usually get the first view, as the rest of the root in a domestic environment, it is very difficult (they do not go to the contact and painful bite).
Pets
Cats - this is the most common human pets.But they are attracted not only by its graceful, beautiful body, but big eyes.But even among the cats have champions - it is British.Their eyes compared to the body is very large, and thus they are not equipped with cilia.But this fact does not stop humming to navigate in the dark.Often you can see how they glow in the dark eyes.Such a phenomenon occurs when a cat falls on its face the light, in which case it is reflected from the body of exactly the same path on which he was on the retina.
This pet with big eyes has a unique vision.Cat is able to see 180 ° and observe what is happening behind her, but she can not see a picture in front of his nose, so she had to connect the touch.That is why cats always on the alert.Interestingly, if necessary, the animal is able to focus the mind on one point.At this point, it seems very focused muzzle and pupils are fully dilated.In addition, it is important to note that the cat can see objects that are at a distance of 60 meters.
Also, for many years it was believed that purring see the world in black and white.But modern technology have proved that it is not.Cats are able to distinguish colors, but this range is not as wide as a person.The main specificity of the Cat's Eye - the definition of gray shades.In any case, this vision is sharper than a human animal six times.But it's a pet with big eyes can compete in their abilities with ostriches, which also take pride of place in the "eyed".
Ostriches

Marine animals
also worth telling about, and the largest eyes in the animals that live under the water.This octopus, cuttlefish and squid.They need good eyesight to survive in total darkness, under a layer of water.At the giant squid, each eye can have a width of about 30 centimeters.This size is really unusual for living beings, but they are needed to see objects, while at a depth of 2,000 meters.In 2007 he was caught squid, whose eyes reached almost 30 cm in diameter, and it was the size of the lens with an orange.It was found that most of these creatures huge eyes on the ground.It is worth noting that scientists have found an interesting fact: the caught animal was only an adolescent female.It weighed 450 pounds, while adult squid can reach a weight of 750 kg.
Dragonfly
Another creature with large eyes and unusual - a dragonfly.The body of her organized more complicated than that of any other creature.Eye of this insect is composed of about 30,000 facets.Thanks to them, a dragonfly is able to see both the back, sides and front of him.So, she can immediately see any danger or approaching food.This dragonfly distinguish color and has the ability to see polarized light.
Gecko listohvosty

Who has big eyes?
On the ground there are many animals that can surprise their appearance, and large eyes.We have considered those to these characteristics exceeded other inhabitants of the planet.We also learned the name of the animal with big eyes, which causes a particular emotion in humans.But it should be noted that this list can be added horses, dogs and many other animals that can move quickly.In these animals the eye in relation to the body is always greater than that of other creatures.This is due to the fact that the speed of a large eyeball helps to better detect moving targets and calculate their speed.
Chameleons
on special stage you can put a chameleon.Although his eyes and may seem small, it is not.These animals have a rather large eyeball, but it is closed almost fused eyelids.But the possibility of this being surprised.His eyes move independently of each other.This "built-in" allows you to watch the chameleon multiple objects simultaneously.However, he completely overlooks the whole area around it, for him there is no "dead zones."In addition, these lizards are able to see ultraviolet light.
