What animal's tail has a strange use? What is the function of its tail? Thank you, everyone.

1, the monkey's tail is to help it jump around and hang it on the tree, and sometimes it grabs food with its tail; The rabbit's short tail can help it escape in an emergency. When the rabbit was bitten by a wild animal, it immediately took off the "leather sheath" of its tail with a "skinning meter", thus winning the time to escape; The squirrel's tail is furry, big and long. When the squirrel jumps from a height, it can slow down the landing speed, so that the squirrel can land safely and play the role of a parachute. Squirrels can put their tails on their bodies when they sleep, or snuggle up to keep warm. 4. The rooster's tail helps it keep its balance; Ducks' tails help them keep their balance. Their tails can secrete a lot of oil. They put oil on thick and light feathers through their mouths, so that they won't get wet by water, and there is always air in them, so that they can float on the water. 6. Peacock's tail can show its beauty, attract the opposite sex, and sometimes play a role in warning and intimidating predators. The function of animal tail Most animals have a tail behind them. People who don't know the ins and outs think the tail is dispensable. In fact, once animals lose their tails, it will bring trouble to their lives. Animal tails have various shapes; Unlimited use. Let's talk about the role of animal tails first. The tail is lacquerware. In summer, standing by the clarified fish pond, you can see the swimming movements of the fish: suddenly passing away, or suddenly stopping swimming, or jumping into the air, or turning around ... it's really changeable and very comfortable. What does the fish swim on? According to scientists' experiments, fish move by fins. If the pectoral fin is broken, the fish will sink forward; If the dorsal fin is removed, the fish will sink back; If the tail (that is, the tail fin) is cut off, the fish will lose its direction and cannot move forward. This experiment proves that the tail is the main organ to push the fish and turn it around. The fish swings left and right by its tail in the water, exerting pressure on the water around its body, gaining the reaction force of the water and making itself move forward. According to the principle that fish wags its tail in water, the working people in ancient China imitated paddles. The fish's tail can't function as a rudder, but it can control the direction when swimming. It is said that as early as the Dayu period, the working people in our country observed the fish turning over with its tail in the water. After repeated practice, they finally invented the rudder. From then on, in the rolling river, ships can run freely like fish. Although platypus living in Australia is a mammal, it lays eggs like a reptile. Its limbs are strong, it stretches out, its abdomen touches the ground and it crawls forward, much like a reptile. At the same time, its mouth looks like a duck, hence the name platypus. There is a webbed toes between the front and rear limbs of the platypus, which plays the role of "paddling" when swimming; Its tail is flat and wide, almost two-thirds of its body width, and it is used as a "rudder" when swimming. Therefore, it is worthy of being a "swimmer." In addition, whales and manatees have a wide horizontal tail fin at the tail, which is not only their powerful propeller, but also their wonderful elevator. The tail is the flight rudder. Birds fly in the air by wings. The coccyx of birds heals to form coccyx, which is hidden at the end of the spine in the body. The short bird's tail has long and wide feathers, which can rotate flexibly like a fan when it is unfolded, so it is easy to master the flight direction, so the bird's tail plays the role of rudder when flying. In people's minds; Birds fly in the sky and fish swim in the water. However, there is a flying fish in the South China Sea and the East China Sea of China, which can jump out of the water for a short gliding flight. Before the flying fish surfaced, it swam quickly under the water. When it approaches the surface of the sea, it clings its pectoral fins and ventral fins to its sides, and then swings sharply in front of its powerful tail, generating a thrust that makes the fish break through the water. Once out of the water, the flying fish immediately spread their pectoral fins and glided against the airflow on the sea. When the flying fish returns to the water, if it wants to take off again, it will beat the waves violently with its tail when it is not in the water to increase the power of gliding and jump out of the water again. In addition, flying lizards in reptiles, flying squirrels and flying squirrels in mammals, etc. Balance your body and control your direction by your tail while gliding in the air. The tail is a balancer. Kangaroos in Australia enjoy the same reputation as giraffes in Africa and become the symbol of Australia. The national emblem of Australia is painted with a jumping kangaroo. There are many kinds of kangaroos, among which red kangaroo is almost as tall as human beings, and its hind limbs are extremely powerful, about 5~6 times that of its forelimbs, and its tail is stout and powerful, up to 3 meters long. Usually, its forelimbs don't land, and its hind limbs and tail are often used to support the body and become a "three-legged incense burner" for rest. Only when eating grass does the forelimb land. It does not walk step by step like horses, cows and sheep, but moves forward enthusiastically with its hind legs, often 3~5 meters high or 5 meters away in one jump; When jumping, the tail is like a "balance beam" to maintain the balance of the body. Our common large mammals, such as horses and cows, also have a long tail with tufts of hair at the end. When they run, their tails stand high and keep their balance. In addition, the long tail with fur is also responsible for driving away flies, flies, mosquitoes and other pests. The cat's tail is very long and connected to the coccyx, which plays a role in balancing the body during exercise. When a cat falls from a tall building, it always lands with its feet first, safe and sound. What is the reason? It turns out that it all depends on the role of the tail. The whole process can be seen in the slow motion of the movie: when the cat falls from the air, its tail is straight and twisted until it feels its tail is in a straight line, and then it lands on all fours. This seems to be a small survival skill of cats, but it inspires experts who study the weightlessness of astronauts and solves their big problems. Scientists have slightly improved the technique of cat landing, allowing astronauts to use their legs as rudders, so that they can walk correctly in weightlessness. Woodpecker is a world-famous beneficial bird in forestry and has the reputation of "tree doctor". Unlike other birds crouching on branches, it sticks to upright tree trunks, chisels bark with a hard and straight beak, and pecks pests that harm trees. The reason why this kind of bird can climb on the upright trunk is that they must grasp the trunk with their toes and support it under their bodies with a rigid and elastic tail as the fulcrum for climbing the trunk, otherwise their bodies will shake and be unstable. The tail is a weapon. Nile crocodile, produced in the upper reaches of the Nile in Africa, is very famous among crocodiles in the world. This crocodile is very big, usually 4~5 meters long, up to 8 meters, and weighs about 1 ton. It is violent by nature, and its long and thick tail is a very dangerous heavy weapon. When it sees cows, antelopes, deer and other mammals drinking water by the river, it will suddenly sweep up its iron whip-like tail, beat these animals in the river, and then open its mouth to have a hearty meal. Other crocodiles will harm people and animals with similar behaviors. The echidna is a special and precious mammal in Australia. It looks like a stinger, covered with hollow needles of different lengths. The thorns on its body are not firmly growing on the body, but the thorns are sharp and have inverted hooks. If an enemy invades, the echidna will turn its back on the enemy and hit him with its tail. At this time, acupuncture will leave the body of the echidna and stab people into the animal's body. It will be very painful for the stabbed person to pull out the thorn! In invertebrates, tails are also used as weapons. Bees and wasps are common insects. They have spines at the end of their abdomen, which are used to communicate with poisonous glands. If people disturb them or destroy their hives, they will sting people with thorns and inject venom into them, poisoning them. Scorpions have a pair of poisonous glands on their tails. When they walk, they will open their tails and tilt their tails to meet their prey. The tail is a sound generator and a warning device. Animals that can make sounds with their tails are really rare. But in some parts of South America and North America, the tail of the famous rattlesnake has this function. Sea otters will beat the water with their tails to warn their companions. There are many kinds of rattlesnakes, the body length is generally l~ 1.5 meters, and the longest is 2 meters. It is a highly toxic snake. Although their tails are different from other snakes, they are not born with stereo sound. The tail end of the newly hatched rattlesnake looks like a button, and the rattlesnake must shed its skin to grow. Every time a layer of skin is shed, the rattlesnake's tail leaves a horny ring, and there is a string of horny rings on the adult rattlesnake's tail, which is the keratinized epidermis left after molting for many times. This keratinized epidermis encloses a cavity, and the cavity is divided into two annular cavities by the keratinized epidermis, that is, two air vibrators. As soon as the rattlesnake's tail shakes, an airflow forms in the cavity. As the airflow vibrates back and forth, the cavity makes a "honk, honk" sound. Rattlesnakes wag their tails 40 to 60 times per second. When it makes the loudest sound, it can be heard from 30 meters away. When some animals around it hear this sound, they often run away in fear. Some scientists also believe that rattlesnakes sound a bit like streams, which is used to lure thirsty animals and is also a way to hunt. Sea otters and skunks are weasels in mammals, and their tails are excellent early warning devices. Sea otters' tails are also tools for boating and building dikes in the water. Sea otters are very sensitive. When it senses the attack of the enemy beast, it will issue a "warning", slam the water with its flat tail and make a crack, so its partner will immediately escape without a trace. Skunks also use their tails as warning devices, but they warn enemies rather than their own kind. If people see a skunk's tail curled into an arch and lying on its back, they should be sensible and avoid it quickly, otherwise the stench from its anal glands will make you faint. Tail is a predatory tool. Bats live in dark places during the day, such as cracks in buildings, tree holes or caves. Some of them hang upside down with their hind paws, while others crawl forward. Go out to hunt insects twice a day at dusk and dawn, and each activity lasts about an hour. The author observed that bats went out to catch insects. When they go out, they climb to the mouth of the cave, lift their bodies with their hind legs, and then take off by using the inertia when they fall. When they take off, they are like kites. From the forelimbs, body, hind limbs to the tail, there is a thin wing membrane, just like the paste paper on the kite and the wings of a bird. Some bats can freely curl the wing membrane between the tail and hind limbs to make it basket-shaped. Why do bats pretend to be hanging baskets? Because they rely on this "magic weapon" to catch bigger insects. Many kinds of monkeys not only have a long tail, but also a winding tail, which acts as the fifth limb when moving in the tree and can help their prey. For example, capuchin monkeys living in tropical forests in Central and South America, with a body length of about 48 cm and a tail length of 50 cm, often flock to the top of trees to look for fruits, insects and eggs. This kind of monkey has a very high climbing ability, and often grabs branches upside down with its hind legs and tail, freeing its forelimbs to collect poultry fruits. What's even more surprising is that when American biologists visited capuchin monkeys in Peru, they also witnessed several adult capuchin monkeys jump vertically to the branches extending into the river, tightly wrapping a branch with only one tail and hanging upside down. Some of them directly touch the water surface with their mouths, and some use their forelimbs as "spoons" to scoop water and drink. Therefore, capuchin monkeys are also called "hanging monkeys". The tail of a snow flea should be a small animal world. If 32 snow fleas are connected in a straight line, it is only 25 mm long. Snow fleas have a flexible tail and can hook food under their bodies. When Ann put down the food, the small tail was released and the snow flea jumped into the air. The tail expresses a silent "language". Tail movements are a kind of "language" of animals, and different movements express different emotions of animals. The most typical and familiar examples are dogs and cats. When dogs see their owners excited or happy, they will wag their heads and tails, and their tails will not only swing from side to side, but also keep spinning. The tail is tilted up to show joy; A drooping tail means danger; The tail does not move, showing anxiety; The tail is picked up to show fear; Shake your tail quickly and horizontally, symbolizing friendliness. A dog's tail can express its feelings. Although it doesn't understand human language, it can distinguish human tones. If you have a kind voice to say to the dog, "bad guy!" " Bad guys! "It wags its tail to show its happiness; On the other hand, if you say sharply, "Good dog! Good dog! "It will cock its tail to show unhappiness. In addition, the frequency of wagging the tail reflects the health and excitement of the dog. The faster you swing, the more excited and healthier you are; A slow swing means that although you are excited, you are in poor health. While hunting dogs, police dogs and military dogs are performing their tasks, the significance of wagging their tails is more abundant and profound. Cats can also express their feelings through their tails. When a cat encounters a new situation or is extremely excited, such as the opposite sex in estrus, the tail tip of the cat often twitches violently; When rats or other animals are found ready to attack, the cat's tail is in a straight line with its body. When the body is lying flat, the tail is parallel to the ground, and only the tip of the tail is slightly shaking. When fighting with your opponent, when you are very angry, the cat will beat the ground violently with its whole tail and make a noise; When frightened and frightened, the cat's tail will tremble. When a cat sits up and meditates, the front end of its tail swings slightly. When begging for food from the owner, the cat's tail will straighten up and form a 90-degree angle with its body. When a cat sleeps, its tail often surrounds itself. Besides these functions, animals' tails have other functions, such as anteaters and other animals with thick tails. When resting or sleeping on the ground, they often put their big tails on their heads and bodies to provide shade and warmth. The different functions of animal tails are an adaptation of animals to their living environment.
