Animal kingdom, which animals are good at camouflage?

Chameleons, they will change their color according to the environment, and can hide themselves well, so that they will not be discovered by predators, so that they can survive and reproduce.

1.Chameleon. Its unique** color changes with the environment.

2.Dead leaf butterflies. Its two wings resemble dead leaves, hence the name, falling in the pile of dead leaves, and the trace is difficult to find.

Personally, I think there are, toad, octopus, frogfish, leaf-tailed geckos, spiny lizards, pygmy seahorses, stick insects, willow leaf eels, chameleons, dead leaf butterflies.

The first, the pygmy hippocampus, is one of the smallest known vertebrates, generally no more than 2.5 centimeters in length. They are mainly attached to corals and look so similar to them that it is difficult for researchers to spot them.

The second, the orchid mantis, is the prettiest of the species of praying mantis. Their limbs have evolved petal-like structures and colors, and they can also adjust their color according to their surroundings, so the petals appear to be very similar.

The third type is the garden palm boat moth, which has flat wings and is cylindrical when the wings are closed. Their heads and tails are covered with short, yellowish-brown hairs, which, combined with off-white wings, make them look indistinguishable from broken twigs.

The fourth type, the dressing crab, this kind of crab is very intelligent, not only dressing itself, but also disguising itself with superb camouflage skills. They often fetch plants and sea lions from their nearby environment to decorate themselves, thus creating a camouflage effect.

Fifthly, stonefish are named for their resemblance to stones, they are very ugly in appearance, they often hide under the reef, their body surface is very similar to their surroundings, and their quilts can secrete deadly toxins, so they should not be easily touched.

The sixth species, lichen ghost beads, is a very small spider with petal-like markings on its back. His legs are often found in knots on the bark or on the surface of branches, making them difficult to spot due to their close proximity.

The seventh chameleon, the chameleon, which we should all be familiar with, is able to regulate its own color by expanding or contracting the pigment cells in **, which is not only conducive to hiding itself, but also conducive to catching prey.

Analysis: This phenomenon is called mimicry in biology, which refers to the phenomenon that some animals are similar to other living or non-living things in terms of shape, color, spotted roses and other physical characteristics. It is an adaptation phenomenon of organisms in nature, the result of long-term natural selection, so it is of great significance to the survival of organisms.

Here are a few common mimicry phenomena –

Sea anemones and sea lilies use plant-like shapes as cover to catch food;

Horned cicadas (also called spiny insects), which can simulate rose thorns and feed;

Aphid-eating flies suck nectar and can stop in the air when flying, similar to bees;

Stick insects simulate the branches of bamboo, and their demeanor is realistic and vivid;

The cuckoo has no nest and lays its eggs in the reed warbler's nest, which is very similar to the eggs of the reed warbler, and the purpose is to ask the reed warbler to incubate the eggs on its behalf;

When the inchworm stops moving, it looks like a dry branch;

The tiger beetle is mimicked as a wasp in terms of size, shape, color, and other aspects;

In addition to the normal two eyes above the head, the eyeball frog also has two identical patterns on both sides of its back.

The dorsal fin of the dace whale has been mimicked into the appearance of seaweed, which can be used to attract small fish that feed on seaweed.

Flies and moths mimic bees and wasps and can escape predation from birds;

A butterfly adapted to the taste of a predator mimics another unpalatable or inedible butterfly that can escape;

Two kinds of unpalatable butterflies imitate each other and share the mortality caused by accidental ingestion by young birds during the learning period.

Some of the butterflies in the Brazilian jungle are similar in color spots to each other, and some inedible butterflies have the same color spots as other edible butterflies (Pink Butterfly family) that are very distant in taxonomic status;

It was first described by the British naturalist Henrry in 1862. He observed that some of the brightly colored species of South American butterflies were almost identical in appearance, but some were poisonous and others were completely non-venomous, and he speculated that these non-venomous creatures were disguised as poisonous in order to escape the doom of eating. He called this phenomenon mimicry, which is known as Bayesian mimicry.

For animals, there are three important reasons for mimicry

First of all, it is conducive to escaping from enemies; When the stick insect flies, the color of the wings is also bright, but when it descends, the wings converge and the color disappears, and the brightly colored insect that is being chased suddenly turns into ordinary branches.

Second, some animals that are not poisonous and lack resistance have evolved into a shape or body color similar to poisonous animals, so that natural predators do not dare to attack them. The yellow and black bands on the butterfly make it look like a wasp; A moth in the family Silkworm Mothaceae, which has a pattern on its wings that resembles owl eyes, which can scare some small birds away.

Third, some animals feed on their mimicry. For example, there is a longitudinal blunt-toothed anchovy in the Pacific Ocean, which resembles a lipfish. While the lipfish removes parasites from other fish, the anchovy also calmly approaches the cleaned fish and then unexpectedly bites off a piece of flesh or fin from the back to satisfy its hunger.

1. Bats. Bats rely on sound waves to find their way and hunt. They emit sound waves that are inaudible to humans.

When this sound wave encounters an object, it returns like an echo, allowing the bat to tell if the object is moving or stationary, and how far away it is. Use ultrasonic echolocation signals to search for food, detect distances, determine targets, avoid obstacles and avoid enemies, etc.

2. Chameleon.

He is good at changing the color of his body at any time with the change of the environment. It is good to hide oneself and catch prey. One theory is that under the regulation of the autonomic nervous system, it is done through the expansion or contraction of chromocytes in **.

3. Gecko. When the gecko is pulled by an external force or encounters an enemy, the tail muscles contract strongly, causing the tail to fall off. Zoology is called "self-cutting".

The nerve of the newly severed tail is not dead, and it keeps moving, and you can use the doppelganger technique to protect yourself and escape. Geckos have a hormone in their body that regenerates tails.

4. Pigeons. Scientists believe that the pigeon's head has a "spatial map" that allows it to fly into unfamiliar areas and know exactly where it is headed. This discovery replaces the current theory that pigeons compare their lofts with the coordinates of their location, and then systematically reduce the differences between the two and find their way home.

Previous theories likened the voyage of a pigeon to a flying robot.

5. Poisonous snakes. Their saliva often shoots from their fangs and is used to paralyze their enemies. Poisonous snakes are generally considered to be venomous, but the venom of a venomous snake can only be used in the blood, and drinking venom does not cause harm to the human body (provided that there is no wound in the mouth).
