Are the colors of the animal world monotonous, and what causes it?

The colors of the animal world are not all monotonous, just because their visual system is different from the human visual system, and the world they see is not what humans seeAlthough the shape of the object is the same, they see the world differently from humans because of the different angles they are in, the way the visual colors are formed. <>

Animal eyes are different from human eyes, which is reflected in the collection of colors, but also in the visual stay and capture, such as human movements, in the eyes of some fierce wild animals, especially felines, are basically slow motion, for example, tigers, his eyes are very keen, he can easily capture animal details that humans can't capture,We now feel that we are moving very fast, but in the eyes of these felines, it is a slow movement, and the colors are different, not a colorful world but a black, white and gray world. <>

The world that humans see is a synthetic world, because there are three primary colors, and then the retina of human eyes is affected by the ratio of the three primary colors, and the colors seen are different, so this makes people see all kinds of colorful worlds, but the eyes of animals are not to see the colorful world of Fenfen, but to survive, only the main goal of human beings now is to see more beautiful landscapes, to see a more beautiful world,But animals are more about survival, they don't have so many bells and whistles, their eyes, their body structure is all about surviving. <>

Man is the strangest animal in the whole of nature, it can be said that it is an animal, but it is more special, because human beings themselves have intelligence, and this direction of physical evolution seems to be different from that of animals, and the direction of human evolution now is that the brain is more intelligent It seems that it is not for better survival, but for better change, but animals,For hundreds of millions of years, the direction of his evolution has been to adapt to the natural environment, and the evolution of human beings is affected by their own behavior.

The colors of the animal world are not all monotonous, and some animals can be seen, but those monotonous animals are often from a different perspective than humans. The way in which vision is formed is also different, which causes the color of things in their world to be monotonous.

Most of the animal colors are monotonous, only some birds, fish, insects, etc. are more colorful, the root cause of this is what are the natural enemies of animals? How do animal mates go about finding them?

The colors of the animal world are mostly monotonous, which is related to the structure of their pupils.

Which animal kingdom is mostly colorblind? The reason, in layman's terms, is that evolution has made survival easier by preserving genes. For example, most snakes barely use their eyes to see their surroundings (high myopia), and all male New World monkeys are colorblind.

What the environment is, finding other predators, and so on, these are just some of the specific reasons why these animals are color blind. While color blindness is a rare condition for humans as mammals, the world is always colorful in our eyes, but we still can't spot colors like ultraviolet light in nature. Of course, the eyes of other mammals on Earth tend to see only black and white.

<> some non-mammalian eyes are really just decorations that are completely incapable of capturing information about the environment. Most of the time, we see color blindness as a disability because it causes a lot of inconvenience in daily life. But the environment in which animals live is very different from ours, and they do not need to distinguish between red and green.

Most mammals are colorblind, mainly because they spend too much time at night. It turns out that when mammals first evolved, they used to live with large reptiles such as dinosaurs.

At that time, mammals were weak. They came out during the day and easily encountered dinosaurs, so they had to be active at night. So, why don't dinosaurs come out at night?

Because dinosaurs, like other reptiles, were cold-blooded animals, their body temperature varied with the temperature of their surroundings. When the temperature drops, it is not good for them to come out at night. As a result, mammals evolved into color blindness because they spent too much time at night, and color vision became useless.

So, humans are also mammals, so why aren't they color blind? Because in the process of evolution, primates began to eat tastier and more energetic plant fruits.

Do a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

Because the structure of the human eye is different from that of animals, the human eye can see many colors through the refraction of light, while the animal eye cannot feel the refraction of light, so it cannot see the color.

Because the human eye is different from the animal eye, the human eye has a cone cell, which can feel the color, while the animal eye generally does not have this kind of cell, so the animal can not see the color.

Because the color difference is caused by the different frequencies of electromagnetic waves, many animals have different frequencies of electromagnetic waves from human frequencies, so they cannot feel the colors.

Because the retina composition of humans and animals is different, the retina of humans can sense wavelengths in a frequency range, while most animals cannot, so this is the case

Because the human eyeball and the animal eyeball are different, the human eye may see many colors through the refraction of light, while the animal eye cannot feel the refraction of light, so it cannot see colors.

1. Chameleon: The chameleon is the rock ptarmigan Jianlu, also known as the snow pheasant, which belongs to the grouse family and is scientifically known as lagopus mutus. Resembles a female mallard.

Like a chameleon, it constantly changes the color of its feathers to disguise itself. In the middle of summer, when the trees are shady and the flowers are blooming, the Yanlei stool bird wears a dark gray "cheongsam" and a dark brown "smock" with a striped coat, shuttling through the vast forest and sea.

2. Chameleon snake: Chameleon is a type of Capuas mud snake, and it is the first new snake species discovered in the past 5 years. It is a venomous snake that lives in the Kapuas River basin of Borneo, Indonesia, and inhabits the wetlands and swampy areas along the river, feeding mainly on rats and fish.

3. Chameleon frog: Chameleon frog, whose scientific name is oreophryne ezra, refers to a new species of frog discovered by American scientists in a small cloud forest in the mountains of southeastern Papua New Guinea, a South Pacific island country, reported by National Geographic. The body color of this species of frog undergoes "amazing" changes, which can be called a "chameleon":

In childhood, they are black with macular spots, and in adults, they become peachy and their eyes turn blue.

4. Chameleon tree lizard: The chameleon tree lizard is a reptile of the genus Tree Lizard of the Iguanaceae family, also known as horsehair snake, thunder snake, and cockscomb snake. Reptiles.

Iguanidae. The head is large and the eyes are small, the body is light brown or gray, the back has 5-6 black-brown or transverse spots, and the tail has dark and light rings. They mostly live under sparse woods and shrubs.

China is distributed in Yunnan, Guangdong, Guangxi, Hainan and other places.

5. Chameleon: chamaeleonidae (scientific name: chamaeleonidae) (English:

Chameleon) commonly known as chameleon, lizard suborder reptiles with bands, native to the eastern hemisphere, mainly arboreal. It is characterized by changes in body color energy. Every 2 3 toes are combined into two sets of toe and terminal teeth, and the tongue is slender and extensible.

The eulizard of the iguana family is found in the Western Hemisphere and is also known as false avoidance.

Take stock of the world's discolored animals! There are even birds that change their faces?

The reason why human beings are called advanced animals, the most significant feature is that they have rich feelings such as joy, anger and sorrow, however, among the more than 1.5 million species of animals discovered by humans, in addition to humans, some animals have very peculiar feelings, they are not only romantic but also very single-minded, do you know the "little secret" of animals?

Studies have confirmed that most mammals are color blind. Cows, sheep, horses, dogs, cats, etc., can hardly distinguish colors, reflected in the color of their eyes, only black, white, gray 3 colors, dogs can not distinguish colors, it looks at the scenery like looking at a black and white**. In addition to their legs, dogs mainly rely on their sense of smell and hearing to hunt their prey.

Our human "close relative" apes live a prosaic gray life. Voles, house mice, yellow squirrels, chipmunks, squirrels, prairie dogs, etc., also cannot distinguish colors. Giraffes can distinguish yellow, green, and orange.

Deer have the strongest recognition of gray. Interestingly, although the zebra is colorblind, it is able to use color to protect itself. Zebras and other animals graze together, and the black and white stripes can attract attention, so when danger arises, all zebras will quickly flee as soon as the lead horse moves.

When the zebra runs, the shaking of the black and white stripes makes it difficult for the predator to quickly determine the distance, and the zebra can escape safely.

This is not the case with birds. With the exception of some birds that are accustomed to nightlife, such as owls, which cannot recognize colors because there are no cone cells in the retina, many birds have a sense of color. Crows fly at high altitudes and need to find a place to land, and the color will help them judge the distance and shape, so they can catch the insects flying in the air and land lightly on the branches.

The birds' ability to discriminate colors is also beneficial in their search for mates. Think about it, male birds often use bright feathers to attract the opposite sex, if they can't feel the color, then what is the charm of male birds?

Most aquatic animals have the ability to distinguish colors. The sea bass can sense color, and the biologists feed them with red larvae, and when they get used to it, they switch to red wool to feed them, and the sea bass actually eats it.

Although insects are lower animals, they are more intelligent than mammals in their ability to distinguish colors. Dragonflies have the best visual appearance against color, followed by butterflies and moths. Flies and mosquitoes can also see the color.

Houseflies hate blue the most, so they are reluctant to approach blue doors, windows, and curtains. Mosquitoes can distinguish yellow, blue, and black, and have a preference for black. Industrious little bees live among thousands of purple and red flowers, but they are red blind, and bees can distinguish three colors: green, yellow, and blue.

However, bees can see ultraviolet rays that are invisible to humans, and can accurately distinguish ultraviolet rays from various shades of white and gray.

Cattle are colorblind and cannot see colors.
