What does the world look like through the eyes of animals? How different is it from the human eye?
All appearances are false, which means that all appearances and appearances are the product of subjective consciousness and do not reflect reality. This sentence is a little scary when you think about it, isn't what we see and feel the most real? But we humans are not the only ones in the world, and what is the world like in the eyes of other creatures?
Today, I will take you to understand the world through the eyes of different animals.
The first type, dogs, dogs can't distinguish between red and orange, but they can clearly see blue and purple, as well as ultraviolet light, dogs' color perception is weak, but dogs have more rod cells than humans, so at night, the dog's eyesight is better than that of humans in a state of low light. We feel like it's pitch black, but dogs can see their surroundings clearly, even tiny flying insects, which may be why they bark inexplicably at night.
The second, cats. Cats only have three colors in their eyes: blue, gray, and green, and they never see red and blue. But cats have a lot of rods and a lot fewer retinal pyramidal cells, and we humans are the opposite, so cats are not as good at detecting color as humans.
But at night, cats still maintain excellent eyesight. Studies have shown that cats are six times more resilient to the dark than humans, and cats have a wider field of view of 180 degrees than humans, and cats have a field of view of 200 degrees.
The third type, birds, is colorful in the eyes of birds, mainly because there are four types of retinal pyramidal cells in the eyes of birds, while there are only three in human eyes, so birds are able to see colors that we can't see, and they can also see various degrees of ultraviolet light. For example, crows are black in our eyes, but in the eyes of crows, they think, ah, they are colorful colors.
Fourth, horses, the world is only blue, gray and yellow. Horses have the largest eyes of all mammals in nature. Maybe many people will think that a horse's eyesight should be very good, but in fact the horse's eyesight is only, and the horse has a very big defect, because both of the horse's eyes are deviated outward, so it has a blind spot and cannot see the world directly in front of itself.
But it has a magical function,The eye of the code can automatically switch between monocular mode and binocular mode,Generally in monocular mode,At this time, the two eyes are in a state of non-interference with each other,Each eye can see the world alone,Only when judging the distance will it switch to binocular mode。
Well, that's all for this issue, see you next time.

Most of the world in the eyes of animals has no color. What you didn't expect was the cow. The world of cows does not see colors.
Its world is just a patch of red-orange-orange. At the same time, the cow doesn't like it when you get close to it because it sees something close to it that is much bigger than it actually is. Birds have the best eyesight, more advanced than humans, birds can see directly under ultraviolet light and have so-called eagle eyes, they can change the shape of the lens, which gives their vision the effect of binoculars that eagles can see.
The lizard is 1 mile away, and all you can see is a pile of sand. Next up is the much-anticipated dog. The world of dogs is close to black, white, and gray.
It can distinguish between different shades of gray and at the same time distinguish small amounts of color, especially blue and purple. Red is dark for dogs, green grass is gray and white for dogs, you throw a bright ball and they only see shapes and not colors.

The world is full of food, and animals can see a wide range of things in their eyes, and their eyesight is several times higher than that of people.

The world in the eyes of animals is not colorful, it is very different from the human eye, and some animals can only see black and white.

<><1. Fish. The eyes of fish may seem very similar to those of mammals, but this does not mean that they have the same perspective as mammals. Normally, the perspective of a fish should be myopic to humans.
This means that they need to be close to see things clearly. Because of their unique eye structure, they may see the image with a slight magnifying glass.
2. Rats. The eyesight of rats is actually very bad, and in their eyes, the world is blue and blurry. But they can perceive their surroundings through their whiskers, and they feel the way their whiskers touch a wall, like a person touching a wall with his hand in the dark.
Since the two eyes are separated, they may see two frames.
3. Horses. A horse's eyes are 8 times larger than a human eye, but horses don't see as many colors as humans, and red will appear greener to horses. This is because they lack red cones and are less able to focus on the center of things than humans.
About 23 percent of horses are short-sighted, and 43% are only able to distinguish details of objects at a distance. But horses have a viewing angle of 350°, which is about 4 times that of humans, because their eyes are on the side of their heads.
4. Dogs. There are three types of cone cells in the human eye, but only two in dogs. This will result in the colors they see less than humans.
Their vision is only sensitive to blue and yellow, but that doesn't mean they have poor vision. In fact, dogs are also excellent nocturnal hunters. They also can't tell the difference between red and green.
In a sense, their perspective is a bit noisy, similar to red-green color blindness in humans.
5. Dairy cows. When cows are grazing with their heads down, the unique structure of their eyes helps them gain a 360° view, which helps them see if predators are approaching. This is a characteristic that is present in most herbivores.
Cows, on the other hand, are unable to distinguish between blue, and are better at distinguishing long-wavelength colors such as red, orange and yellow, and less so at purple and gray.

Question 1: Which animal has the most eyes in the world Dragonfly.
The eyes of insects are unique, and almost every one of their eyes is made up of thousands of small hexagonal eyes arranged in close proximity. And each small eye has its own posture system, each with a refractive system and sensory cells, and all have vision, this peculiar eye, zoological called "compound eye".
The compound eyes of dragonflies are the largest and most numerous in the insect kingdom, accounting for two-thirds of the total area of the head, up to about 10,000 birds, 10 times that of ordinary insects, and the structure is very peculiar: the upper part looks at the distance, and the lower part looks close. In this way, when it catches small insects in the air, it can be handy, and it will never miss.
Scientists imitate the structure of dragonfly eyes and build a compound eye camera, which can take thousands of photos at a time.
It turns out that the dragonfly's compound eyes are particularly large, and its two large eyes are made up of 1,000 to 28,000 small eyes, and most of the insects' eyes are immobile. But dragonflies' eyes can move freely with their necks, so dragonflies can look around and around.
If you speed up and shake it in the upper part of its eyes, it will be dizzying, and you will easily catch it, which is also the weakness of dragonflies with many eyes.
Question 2: What animal has the most eyes in the world The animal with the largest eyes: The eyes of the king squid are the largest eyes in the world, with a diameter of up to 38 centimeters, the eyes of the blue whale are only 12 centimeters, and the diameter of an ordinary record is centimeters.
The king squid is a giant spear squid and the largest invertebrate in the animal kingdom. It is said that the longest king squid may be about 30 meters long. These animals live in the deep sea below 3,000 meters, which is extremely rare to see, and they are the favorite food of sperm whales, but sometimes they can kill sperm whales because they often use their tentacles to choke the sperm whale's nostrils.
Question 3: What animal has the largest eyelids in the world The blue whale is the largest mammal in the world, found in all oceans and seas around the world. It can reach a length of about 30 meters, weigh about 170 tons, and can open its mouth to a width that can accommodate 10 adults to enter and exit freely.
In November 1896, a pile of marine animal carcasses weighing 6 7 tons was found on the San Gustine waterfront in Florida, USA, and it was not until 1970 that the remains were determined to be octopus remains, and it was estimated that the brachiopods could reach 61 meters.
However, no octopus of this size has been found yet.
Have you ever seen the movie "Extreme Deep Cold", which is the big octopus talked about by clan friends, it is very good-looking.

As a result of natural selection, animals have eyes that are uniquely adapted to their environment, and their eyes come in a variety of shapes and sizes. Let's follow me to see which animal in the world has the biggest eyes.
Q: What animal has the biggest eyes in the world?
Answer: King squid, eyes can be up to 41 cm long.
Morphological characteristics
They live in the deep waters of the Pacific Ocean and the Atlantic Ocean, with a body length of about 20 meters, a weight of about 2-3 tons, and a diameter of 41 centimeters in the diameter of one eye, making them the largest lightless vertebrates in the world. It has an extremely ferocious temperament, feeds on fish and invertebrates, and can fight giant whales. There are often reports abroad of king squid fighting sperm whales.
Living environment
Although scientists still know little about the specific habitat of this mysterious creature in the deep sea, they believe that king squid may be more inclined to live in colder bodies of water, and that their blood does not seem to be good at carrying oxygen at higher temperatures. It is thought that the king squid may have a well-developed nervous and brain system.
Legend of the squid
It is recorded that on one occasion a king squid was seen stalking a sperm whale with its thick horned hands and suckers, and the sperm whale used all its strength to bite the tail of the king squid. The two giant beasts of the sea tumbled violently, stirring up turbid waves into the sky, and then both sank to the bottom of the water, and did not know what to do. Most of these fights are won by sperm whales, but there have also been cases where the king squid has suffocated the whale by clamping its nostrils with its reckless hands.
A squid with a length of rice was measured with a centimeter diameter of a sucker on its horn hand. However, from the captured sperm whales, sucker scars with a diameter of more than 40 centimeters have been found. It is speculated that the king squid that has fought with this whale may have been more than 60 meters long.
If there really is such a big king squid, it is not far from the legendary Norwegian sea monster.
Peculiar eyes
According to the University of Michigan Museum of Zoology, in addition to its huge size, the king squid has the largest eyes in the animal kingdom, almost the size of an adult's head. This peculiar shape may have been designed to help the king squid see clearly in the dark environment of the deep sea. King squid belongs to cephalopods, a group that includes squid, octopus, squid and other close relatives.
Yes, in the Brazilian Amazon, there is a fish called man-eating pomfret that is very small in size and has sharp teeth, which can eat people, and it is said that if people want to cross the river, they must first throw a dead cow in the water, and when they eat the cow, take the opportunity to cross the river. >>>More
