What animal s eyes see far?What animals look near and not far

YesEagleeyes see the farthest.

Eagles are known for their good eyesight, and they can see 36 kilometers in range, which is six times that of humans. Why is the eagle's eyesight so good?This is due to the unique structure of the eagle's eyes.

The retina in every human eye.

, there is a groove, called **concave, and eagle eye.

There are two concave concaves. These two concaves have different functions, one of them is specifically used to look ahead, and the other is specifically used to look to the side. In this way, the eagle has a much wider visual range and can take into account both the front and the side.

In addition, the eagle has six or seven times more cells than us humans in the fovea used to see. The eagle's eyes not only see farther than other animals, but also see more clearly. Eagles can accurately distinguish animals on the ground, even snakes and voles at an altitude of several kilometers.

It can't escape its eyes.

It is difficult for the human eye to see small insects from 20 meters away, but it is very easy for eagles, who can see small insects even 100 meters away. The eagle's eyesight is so sharp thanks to their well-developed visual system. Cone cells on the retina of the eagle eye are particularly numerous, per cubic centimeter.

There are about 1.5 million of them, but there are only 200,000 in the human eye, which means that the eagle's eyesight is eight times sharper than the human eyesight.

Due to their physiological structure, habits and other characteristics, some animals tend to show outstanding abilities in certain aspects, such as vision. The animals mentioned here that "see near but not far" refer to animals that have excellent near vision, but not very good long-distance vision. Such a statement is often applied to birds and insects.

Because these two types of animals rely more on vision for important life activities such as food acquisition, mating, and territorial competition.

There are many species of birds, such as parrots, pigeons, eagles, eagles, etc., which can clearly see their prey at close range, but their eyesight is not ideal for distant objects. An important reason for this is that the crystals in the birds' eyes are usually spherical or hemispherical so that their eyes can see wider and more thoroughly. However, this special shape makes the bird's eyes have a stronger defocusing ability, and for distant objects, the point where light gathers on their retina is relatively large, so the roller ruler affects the visual clarity.

Insects are another group of animals that have very good near vision, such as bees, flies, and ants. These insects often forage in close proximity to flowers and other plants, so they need to see the details of the plants accurately and clearly. But their eyesight is relatively weak when it comes to things that are far away.

Some insects' eyes are made up of many tiny compound eyes. Compound eyes allow them to see the movement of their prey in a wide range, but only vague outlines.

In general, these animals usually take full advantage of their near vision and use it to promote their own survival, which represents an ingenious evolutionary mechanism for organisms to adapt to their environment. <>

Some fish don't have their eyes looking to the side. This is because their eye inclusions are fixed to their skulls and cannot move freely like humans or other animals. This usually happens to deep-sea creatures, because in the deep sea, vision becomes less important due to the lack of light.

Instead, they rely more on other senses, such as sensory and lateral line systems, to detect their surroundings. In addition, some insects, such as dragonflies and locusts, have similar eye structures. Their eyes are divided into thousands of individual hexagonal patches, each with its own photoreceptor cells and neurons, allowing them to see objects and movements around them, but not to change direction like other species.

For deep-sea creatures, the ability to move freely without the need for eyes may be due to the fact that the underwater environment is so dimly lit that little information about the environment is seen in the eyes of ordinary animals. On the contrary, a growing number of deep-sea creatures have evolved different characteristics, such as glowing organisms and long tentacles in their bodies that are used to attract prey or sift through food sources. This is further evidence that good hearing, smell and sensation are more important than strong vision in a deep-sea environment.

However, the feature that the eyes cannot move freely can also be found in other ants. In addition to fish and insects, some reptiles such as snakes also have a similar eye structure. This is due to the fact that they do not need to reorient themselves between environments, but rather perceive their prey through their sense of smell and thermoreceptors.

In addition, some birds have similar eye splits, as they need to focus most of their attention on the ground in search of food.

In nature, different animals have different limitations and characteristics that help them better adapt to their environment and survive. Although fish have more fixed head features than other animals, the strength of other sensory organs does not prevent them from hunting in deep-sea environments. <>

The eyes of the snail are on the antennae. The snail has two pairs of antennae, and in its larger posture, the tip of the pair of antennae has eyes. The head of the squid has a pair of well-developed eyes on both sides, and its structure is relatively complex, the outermost part is a transparent cornea, without holes; The middle layer is the sclera, and the peripupillary area is buried iridescence.

The starfish's five eyes grow on the tips of each of the five feet. <

1. The snail's eyes are absolutely on the antennae. The snail has two pairs of antennae and eyes at the tip of its larger pair of antennae.

2. There are a pair of developed eyes on both sides of the squid's head, and its structure is relatively complex, with a transparent cornea at the outermost point and no holes; The middle layer is the sclera, and the peripupillary area is iridescence.

3. The starfish's five eyes grow on the tips of each of the five feet.

4. The owl's eyes are located directly in front of the face, and it has excellent depth perception during hunting, especially in dim light environments. The big eyes are fixed in the owl's eye sockets and cannot be turned at all, so the owl has to keep turning its head.

5. The two eyes of the flounder are born on the same side, and the other side has no vision.
