In nature, almost every animal has its own "mask". The fur of deer, squirrels, hedgehogs, and some other mammals is brown (also called "earth color"), which blends in with the colors of trees and soil on the forest floor; the fur of sharks, dolphins, and many other marine animals The skin is grey-blue, which helps them blend in with the soft, light-colored environment underwater; when a fawn stands in the tall grass. From a distance, the spots on the deer's body are very similar to the spots formed by the sun on the forest floor; the sea cucumber lives on the bottom of the sea, its body color is gray, and it looks like a stone on the bottom of the sea when it is lying motionless.
The "masks" of some animals will change with changes in the environment, such as the North American ptarmigan, which is variegated in autumn and pure white in winter, because winter is a snowy season. Flounders can be said to be "experts in color change". They live on the seabed and are covered with messy spots that look like a pile of seabed gravel. What's even more peculiar is that it can move the pigment cells on its skin at will according to different habitats, so that the color of its body changes according to different environments. But once a flounder's eyes are unfortunately damaged, they lose the ability to change their body color. In order to survive, flounder also has a unique trick, which is to simply bury its entire body in the sand on the seabed so that no one can find it.
Chameleons, octopuses, squids, etc. have well-developed body surface pigments, and the frequency of changes is much faster. They will constantly change their colors while traveling. On the trees, it is green, and on the ground, it is green. It turned brown again, almost like a magic trick.
If flounder and chameleons are experts at adapting to changes, then gobies, sunflower shrimps, and jellyfish are definitely masters at adapting to changes. The goby is completely transparent and invisible. Even if there are enemies around it looking at it, it will be as if it is through a layer of glass and will not be aware of its existence. The sunflower shrimp hides among the corals, and is completely transparent except for a few scattered black, white, and gold spots that mark the location of important organs in its body. The same is true for the colorless and transparent jellyfish. It is invisible in order to better hunt. It is invisible, dragging its long whiskers and wandering around. It seems weak and weak, drifting with the water, but in fact it relies on its own strength to keep swimming forward. , looking for food. They eliminate the choice of color and the trouble of changes, making camouflage truly superb.
There are also some animals that can cleverly combine the concealment and appearance of their bodies. The fisherman spider uses branches as "fishing rods" in the woods. It spins out a long spider silk at the end of the rod, and wraps a mess of silk underneath to make "fishing line" and "fishing bait". Insects flying in the forest see the "bait" floating in the wind and mistake it for their favorite food. When there is no wind, the fisherman spider pulls the "fishing line" with its feet, causing the "bait" to swing back and forth, setting up a "fascination array". Once an insect takes the bait, the mucus on the tangled threads will bind the insect's hands and feet.
Some fish are known as "fisherman on the bottom of the sea". Its mouth is large and its teeth are very sharp. The first thorn on the back of this fish is thin and long, bent above the head. This is its "fishing rod." Usually, it lies deep in the seabed or buries its body in the sand, but it has this "fishing rod" raised high. On the top of the "fishing rod", there is a glowing sarcoma. When the fish saw it, they thought it was a delicious meal, so they swarmed up and eagerly pounced on it to taste it. Unexpectedly, the fish opened its mouth wide. The soft and elastic "fishing rod" immediately brought the hooked fish to the mouth.
In the seabed of Europe, America, Africa and the coast of my country, the "fishing rods" of various fishes are different: some are inserted on the upper jaw, and some grow on the lips, like a white rod. beard. Some of the sarcomas on the "fishing rod" are like neon lights, red for a while, white for a while, just turning blue, and then turning green again, colorful and dazzling.
Some animals are "kind" in nature, but in order to prevent harm from foreign enemies, they do not hesitate to use a "brutal" face to defend themselves. Butterflies, blue-ringed octopuses and other animals use their body color to warn enemies. The brighter the colors of these animals, the more toxic they are. Those who dare to boldly declare their existence in nature must have powerful and deadly weapons. Because he has the means to kill him, the enemy is intimidated and does not dare to act rashly.
Some non-venomous snakes will deliberately imitate their venomous counterparts. They will swagger around and use similar colors and patterns to scare off opponents. Some non-venomous butterflies have evolved. They develop patterns similar to those of poisonous butterflies, thus deterring their natural predators, birds.
In South America, certain brightly colored butterflies are almost identical in appearance, but some are venomous, while others are completely non-venomous. These non-venomous creatures disguise themselves as poisonous to avoid being preyed upon. This phenomenon is called "mimicry." There is a lizard with no legs and a slender body. When it swims, everyone thinks it is a snake, but its eyelids blink. This is the only way to identify its identity.
In order to survive, animals continue to make breakthroughs in camouflage techniques, and some species have even reached the point of imitation and mimicry. Most of the objects they imitate are plants and rocks, such as stick insects, grass leaf insects, and leaf moths. Even their movements are like hanging on the branches and swaying, like leaves shaking in the wind.
The sea dragon in the ocean is shaped like a long green leaf, floating left and right in the water. If it weren't for its two small eyes, who would know that it is an undersea animal?
There is a kind of spider, if it crawls Among the yellow flowers, it looks like a yellow flower. If among the white flowers, it becomes white again. There is also the orchid mantis, which looks very much like an orchid. It even imitates the details of the orchid so that it is difficult to tell whether it is genuine or not. You cannot use conventional concepts to find its head and body. The whole thing is just a blooming orchid, so beautiful. Huan. As this "flower" stalks its prey, few insects can escape this beautiful lie.
What kind of "mask" animals wear is the result of the interaction of genetic genes and natural selection. In the long-term competition of species, most animals have evolved some kind of natural camouflage to help them find food or avoid enemy attacks. In the wild, the closer an animal's coat color is to its surroundings, the less likely it is to be spotted by predators, and therefore the longer it lives. As a result, animals that are more closely integrated with their surroundings have more offspring than those that are less integrated. Children who inherit the genetic advantages of their parents will develop the same camouflage color as their parents, and they will then pass this camouflage color from generation to generation. The end result is that entire species evolve ideal camouflage colors that blend closely with their surroundings.
