Why are brightly colored animals often highly poisonous?

We don't know much about how these biological structures evolved, but at least we know how they came to be, how they produce beautiful colors, and nature doesn't have sophisticated technology such as electronic cameras to etch thin film materials, so it has to rely on clever construction, and if engineers can master these principles, they may be able to develop cheap cloth that can change color at any time like the squid protective color, or convert the electronic circuits in computer chips into optical channels that can transmit information at high speeds.

The most poisonous animals in the world are Xi Chong: box jellyfish, Ekiterin sea snake, blue-ringed octopus, stonefish, leaky filial piety Lu Bi bucket spider, etc., there are many animals in nature that are poisonous, and the species and lifestyles of these animals are different. Regarding the specific introduction of "poisonous animals", if you are interested, you can continue to read and understand.

1. Box jellyfish.

Box jellyfish is the most poisonous creature known at present, the representative is the Australian box jellyfish, an adult box jellyfish has billions of poison sacs and poison needles, just touching the box jellyfish, will have a huge danger, its venom mainly acts on the heart.

2. Agetling Sea Serpent.

The Ekiterin sea snake, also known as the green ring sea snake, lives in the same sea area as the box jellyfish and is one of the most venomous snakes in the ocean, and its venom mainly acts on nerves.

3. Blue-ringed octopus.

The blue-ringed octopus celery is a small species of octopus, but it is highly venomous, known as the "most venomous sea creature" along with the box jellyfish, and its venom mainly acts on the nervous system, although it rarely actively attacks humans except when attacked.

4. Stonefish.

Stonefish is a highly toxic fish, the appearance is like a stone, there are more than ten spikes on the back, if attacked, it will emit highly poisonous, its venom will cause severe pain and swelling, and even cause human spasms, syncope, and even death.

5. Funnel-shaped spiders.

The funnel spider is one of the deadliest spiders in the world, extremely aggressive, and after being bitten by a funnel spider, its symptoms are determined by the toxins released by the spider, and its venom mainly acts on the nervous system.

<> when outdoors, some animals cannot intuitively judge whether they are poisonous or not, but generally animals with bright colors, strange shapes or more patterns on their bodies and look relatively unfamiliar are poisonous.

I don't know what kind of exactlyScientific name.

Eublepharidae Eublepharidae Eublepharis Scaly reptiles

It has movable eyelids, so most reptile owners call it "eyelid geckos". It inhabits between flat land and mountainous areas, and its traces can be found in all rocky wastelands or grassland areas. The terrestrial type is centered on a male guarding the palace and adopts a polygamous lifestyle.

During breeding, males engage in fierce fights for mates. During the day, they often hide in rock crevices, and only go out to forage for food after nightfall.

Native to the surrounding areas of India and Pakistan, inhabiting deserts or grasslands, often sheltered by stone crevices or holes, leopard guards can be seen in most reptile pet shops today.

It is a kind of gecko, called Henan Shougong, also called Bawangling Shougong.

Hainan eyelid tiger, also known as Hainan Shougong, eyelid Shougong, is an endemic species in China, distributed in the karst landform, tropical rainforest or monsoon forest of Hainan Province, China's wet ground, like cold and humid environment, nocturnal, feed on insects.

Lizards, also a bit like geckos, geckos are poisonous.

The more beautiful things are, the more dangerous they are, we see some brightly colored animals in nature, and often can't help but be curious to look at them twice, but sometimes it is this curiosity that kills people, there is a law in nature, often the most colorful animals, the more toxic it is, their bright colors seem to be a warning color to humans, so when we see these bright animals, the farther away from them.

First, the physical harm caused to human beings when we come into contact with or eat these brightly colored and poisonous small animals, if the symptoms are relatively mild, it may cause uncomfortable vomiting, dizziness or blisters on the body, if it is more serious, it may be directly fatal, so those explorers would rather eat some wild grasses, than hunt those brightly colored small animals, these small animals are often more flexible, difficult to be caught, which is also the protective color of those animals, can better hide themselves, not to be discovered.

Second, the warning of the animal The color of the animal body is to warn the predators to stay away from them, the European salamander even when you touch them with your hands, their venom will seep out of the **, and the European bell toad, when overly frightened, the toxin will immediately spread all over the body, the animal's toxin is not only for people but also for other animals, when they are attacked, ** surface will spew out toxic mucus to protect themselves, will not be easily harmed. So when we encounter these animals outside, we must protect ourselves and don't let curiosity hurt us.

Third, locusts and locusts, which are a headache for foreigners, seem to have become a delicacy on the table of Chinese, but there are still some brightly colored yellow worms, do you dare to eat them? Most of the common locusts are greenish, but they have some brighter locusts, covered in rainbow colors, and when they are harmed, they will also spray a kind of venom, although it is not fatal, but it can also protect themselves, and most of these locusts will eat poisonous plants, so that they have their own venom.

In fact, the brightness of the color is not directly related to its toxicity, the brightness of the color is mainly determined by its own genes, such as some colors are very bright, but they are also non-toxic and harmless, such as some peacocks, they do not have any poison. There are also some plants that are like this, so there is no strict scientific basis for this.

Not necessarily, there are some animals and plants that are brightly colored and poisonous, such as a poison dart frog, which has a bright appearance and strong poison. But there are also cobras, which are inconspicuous animals and are also very poisonous.

That's definitely not, whether the food is toxic or not has nothing to do with the color of the food, like red dragon fruit and the like, the color is so bright, it is also non-toxic.

Generally speaking, this is the product of the evolution of nature, and bright colors are a warning to each other of their own dangers, but some are exceptions, such as some fruits.

Because colorful colors are a reminder that we are poisonous, and it is also meant to protect ourselves.

Colorful animals are not colorful at the beginning, they are often very powerful, and they have existed for a long time, in order to adapt to the environment and avoid natural predators, they have evolved into colorful, and the originally slightly poisonous animals will also strengthen their own defenses, doubling their toxicity.

This is the protection mechanism of animals, and color is used in nature to distinguish the degree of danger. The brighter the color, the more dangerous it will be.

Because many poisonous animals hunt by relying on their own colorful ** to attract prey close to themselves, and then poison them. So poisonous animals are generally colorful.

For creatures in nature! Colorful ones generally serve two purposes:First, attract the attention of others.

In nature, the color of animals all has its function, which is the result of natural selection in the biological world. Some animals are the same color as their surroundings and are mainly used to camouflage themselves, while others are not. Peacock open screen, the color is very bright, the purpose of peacock open screen is to use for courtship during the breeding period on the one hand; On the other hand, when threatened by natural enemies, it is used to deter and warn enemies and protect themselves.

Therefore, for many animals, color is a warning message to predators, as if to say to predators: I am in danger, you should not approach me. Wasps, also called hornets, are more common in the wild in rural areas.

Wasps are known to sting, and we have heard of stinging incidents from time to time. The taste of being stung is not pleasant, the pain is very severe, mild cases lead to ** redness and swelling, severe cases may appear dizzy, allergies, and even transient shock. The wasp is generally black and yellow in color, and his color is a warning message - do not approach.

Wasps generally do not sting on their own initiative, and when natural predators approach them, they will sting when they feel threatened.

Frogs have many natural predators, and any carnivore can easily eat frogs. But this brightly colored frog is not daring to touch even if the tiger sees it. This is the poison dart frog, which mainly grows in tropical forests, and has a variety of colors, including green, yellow, and blue.

These coloured poison dart frogs** are highly toxic, and milligrams of these toxins can kill people, and a single poison dart frog can poison 20,000 mice. It is also because of its toxins that primitive hunters in Panama and Colombia often used bows and arrows to dip the toxins of these poisonous dart frogs for hunting.

This may be due to the fact that brightly colored animals tend to secrete toxic substances in order to protect themselves.

This may be that he is more colorful, so he is vulnerable to attack. It's got to be poisonous.

I'm curious, many people say that bright colors can warn enemies that they are poisonous and dangerous. But in fact, almost all animals except humans have black and white eyes in their eyes, and only a few birds can recognize red. Since what is the use of such bright colors?

Or is the way animals recognize colors very different from people? It's a mystery.

That should be a way for him to protect himself, too colorful, too obvious in his goals, and then evolved this ability.

Because brightly colored animals are easy to spot, they also represent a danger signal.

It is the natural evolution of living beings to act as a deterrent and warning to the enemy.

May be easy to spot in the wild. So secrets are created in the process of evolution**.

Because things with bright colors are easy to attract people, they are toxic to protect themselves.

Because they are bright colors that were created to protect themselves.

Because this creature has a large amount of material left in its body, it will show a special color.

Vivid is a warning effect, or used to seduce other creatures.

Strictly speaking, it is not that the brighter the animal, the more poisonous it is. This belongs to the protective color of animals in nature. Some bright colors may be highly toxic to protect themselves from predators or others.

But this is a protective color. The color of the animal's appearance is similar to its surroundings, and this color is called a protective color. Many animals have protective colors, similar to the pattern of a leopard and the green of a frog, and many will change color, but the highest level is mimicry, not only color, but also the appearance has completely changed (the color and appearance are similar to the environment are classified as mimicry).

There are many creatures in nature that rely on protective colors to avoid enemies and save themselves in the competition for survival.

There are many examples of this protective color in the animal kingdom, and we can meet it at almost every step of the way. Most of the animals in the desert have a yellowish "desert color" as their characteristic. Lions, birds, lizards, spiders, worms, etc., in short, can be found in all the emblematic animals of the desert fauna.

On the contrary, all the animals in the northern snow, whether it is the terrible polar bear or the petrel that does not hurt people, are covered in a layer of white, and they are simply not visible against the background of the snow. The color of the hare's coat is earthy yellow, which is also the color of most plants and trees in autumn, so the hare can escape from many predators. Chameleons are a type of lizard and are typical animals with protective colors.

It can quickly change its body color in the reflection of light from its surroundings, changing to the color of the trunk or leaves to protect itself. Everyone who catches insects knows that it is very difficult to find insects because of their protective colors. You might as well try to catch the green grasshopper squeaking in the grass at your feet, and you can barely see the grasshopper in the green background that covers it.

There are also butterfly moths and caterpillars that live on the bark, and the color is very close to the color of the bark (such as poison moths, etc.).

The same is true for aquatic animals. The marine animals that live in brown algae have a "protective" brown color, making them invisible to the eye. The main protective color of the animals that grow in the red seaweed area is red.

The silver scales are equally protective, protecting the fish, even if they are not harmed by the birds of prey that search for them in the air, and from the big fish that threaten them underwater: not only does the surface of the water look down like a mirror from above, but from below, from the deepest part of the water it looks up like a mirror (total reflection), and the silver scales blend in with the shiny silver background. As for jellyfish and other transparent animals in the water, such as worms, shrimps, molluscs, etc., their protective color is completely colorless and transparent, so that the enemy cannot see them in the colorless and transparent natural environment.
