"Desert Mickey Mouse" was discovered in Jiuquan, Gansu Province, with a long tail and big ears, and developed hind legs like kangaroos

In a construction site in Subei County, Jiuquan, Gansu, workers accidentally found some movement in the dry well of the construction site, and checked that it turned out to be a "rat". But the workers felt a little strange. We have seen a lot of mice, some big and small, but this "rat" is different. Not to mention that the general mouse is gray-brown, but it has a khaki color. In addition, the ears of this mouse are very large, like those of a rabbit, and the tail is different. It is long and has a tuft of hair at the end of the tail, such as Spike-like. Most mice have relatively short limbs, and they walk as if their abdomens are on the ground, but this "rat" has particularly long hind limbs, and it jumps and jumps like a kangaroo. The workers noticed that something was wrong, and it was obviously not an ordinary rat, so they contacted the local police. After the staff arrived, they did find the "rat" in the corner of the dry well. As described by the workers, this "rat" is indeed different. It hid in the corner, its eyes were frightened, and its body trembled from time to time. People speculated that it might be injured, so they captured it for rescue. After careful inspection, it was found that one of its legs was injured, and the police used iodophor to disinfect and reduce inflammation of the wound. At that time, people saw this animal for the first time, and after checking the information, they found out that this strange "rat" was called a long-eared jerboa.

It looks cute and is known as the "Desert Mickey Mouse"

The long-eared jerboa is a species of jerboa, and their size Relatively small, even smaller than most house mice, weighing only 30-40 grams as adults. Typical features of this animal are a pair of large, long ears resembling rabbit ears; a small snout, but somewhat similar to a pig's nose; a slender tail with a black base at the base and a white tip at the tip; slender and strong The hind limbs are very conspicuous. Proportionally, the hind limbs of the long-eared jerboa are as developed as the kangaroos, and they rely on it for daily walking and jumping. Long-eared jerboa are mainly distributed in Gansu, Inner Mongolia, Qinghai and other northwestern regions of China and Mongolia. There are also some differences in the coat color of populations in different regions, mainly light yellow brown, light red brown, sandy gray or khaki. The "Mickey Mouse" in the film and television works has a pair of big ears and a cute image. Some of the external features of the long-eared jerboa are somewhat similar to Mickey Mouse, so they are also called "Desert Mickey Mouse". The long-eared jerboa is a rather strange animal, and people don't know much about it, and it's basically based on textbook knowledge. They are very timid, and they will immediately flee back in case of circumstances, but after jumping for a certain distance, it will slow down, stop, and then start to forage around, obviously forgetting the danger just now. If there is a new situation, they will repeat the above action.

Large ears are the protection of hearing, and well-developed hind limbs represent strong jumping ability

The environment in which the long-eared jerboa lives is relatively desolate, generally desert areas. It is said that to survive in this environment, the temperature difference between day and night is large, and food is scarce. In order to save the body's precious energy and reduce heat loss, the animal's body will undergo adaptive changes, such as becoming more hairy, smaller ears and so on. Like the hozen, the tiny ears are not even visible under the cover of long hair. But the long-eared jerboa doesn't seem to take the usual path. Not only did their ears not become smaller than the average mouse, but instead, they became abnormally large. Why? Maybe for survival reasons. Long-eared jerboas are undoubtedly the weaker side in the desert ecosystem, and are the basic prey of many predators, and escape is their only way to save their lives. They are nocturnal, hide in burrows during the day to rest, and come out to feed at night. In order to evade predators at night, it needs extremely acute hearing to perceive anomalies around it. In addition, long-eared jerboa mostly feed on some insects, they can hear the sound of insects flying, and then use sound positioning to prey on these insects. If big ears are the guarantee of their hearing, then the developed hind limbs allow them to have a strong jumping ability. Once they locate the flying insect, they quickly jump up to catch it.

Jumping high, long, and turning in the air

As you can see from their name and body structure, this is an extremely good Small jumping animals, they have well-developed hind limbs, usually just like kangaroos, jumping and walking. Long-eared jerboa can reach a height of 1 meter and a distance of up to 2 meters if they jump hard, and their jumping ability is even stronger than that of kangaroos. Coupled with their keen hearing, it is still quite difficult for predators in the desert to catch them. Animals living in this type of environment almost have their own survival tricks, otherwise they would have been wiped out by other animals. However, such ecosystems are relatively more fragile, and species are more affected by environmental changes. For the jerboa, the biggest threat comes from environmental damage. Jumping high and jumping far is the basic operation of the jerboa, but did you know it? They also have a unique trick, that is, when they jump into the air, they can still turn, which is very powerful. For example, when they were chased by predators, they found that they were about to be caught. Suddenly, they made a sharp turn in the air, caught the predator by surprise, and had the opportunity to escape. Long-eared jerboa are able to do this thanks to their long tails. When they need to turn in the air, they swing their tails hard to gain a turning force. Long-eared jerboas have been living on the earth for millions of years. They need to hibernate. After waking up from hibernation, they will mate in a short time. They can have 2 litter a year, and the number of litter is 2-6, so they The reproductive capacity is still quite strong. However, as mentioned earlier, the environments they inhabit are relatively fragile, so species living in such environments are more affected by environmental changes.
