Giant panda (scientific name: Ailuropoda melanoleuca): the only mammal belonging to the genus Ailuropoda of Xiong Ke, a carnivore, with a head length of 1.2- 1.8m and a tail length of 10- 12cm.
The weight is 80- 120kg, and the maximum weight can reach 180kg. It is black and white, with round cheeks, big dark circles, chubby body, iconic walking posture, with eight characters in it and claws as sharp as scalpels.
Giant pandas have lived on the earth for at least 8 million years and are known as "living fossils" and "national treasures of China". It is the image ambassador of WWF and the flagship species of global biodiversity conservation. According to the third national wild panda population survey, there are less than 1600 wild pandas in the world, which belong to the national first-class protected animals.
By the end of 2011/the number of giant pandas in captivity in China was 333. Giant pandas eat meat at first. After evolution, 99% of their food is bamboo, but their teeth and digestive tract remain intact and they are still classified as carnivores. When they are angry, they are as dangerous as other bear species.
The life span of giant pandas in the wild is 18-20 years old, and they can be over 30 years old in captivity. By 20 18, 1 1, the number of giant pandas in captivity had reached 548.
2. Siberian plain wolf
Siberian plain wolf (scientific name: Canis lupus campestris): It is a subspecies of gray wolf, a predator in the upper part of the food chain and the ancestor of Haschi in Siberia.
Usually in groups. They live in forests, deserts, mountains, frigid grasslands, Siberian coniferous forests and grasslands, and are the largest members of wild canines in the world. Good endurance and suitable for long-distance migration. Their narrow chest and strong back and legs give them efficient mobility.
They can walk more than ten kilometers at a speed of about 10 kilometers per hour, the speed can be increased to nearly 65 kilometers per hour when chasing prey, and the distance of each step can be as long as 5 meters when sprinting. Because they preyed on sheep and other livestock, they were not killed by humans until the end of the 20th century.
3.koalas
Koalas, also known as koalas, are Australia's national treasures and rare primitive arboreal animals. The English name of koala bear comes from ancient aboriginal characters, which means "don't drink". Because koalas get 90% of the water they need from eucalyptus leaves, they only drink water when they are sick and dry. The locals call it "Kwale", which means "no water".
Koalas are not Xiong Ke animals, they are far apart. Xiong Ke belongs to Carnivora, while koalas belong to marsupials. It sleeps 18 hours every day, with a gentle temperament and a simple and honest posture.
4.kangaroos
Kangaroo is any marsupial of Kangaroo, which is mainly distributed in mainland Australia and parts of Papua New Guinea. Some of them are unique to Australia. Different kinds of kangaroos live in different natural environments in Australia, from rainforests and desert plains with cool climate to tropical regions. Kangaroos are the highest and farthest jumping mammals.
Kangaroos sometimes refer to all marsupials. The word comes from Guugu Yimidhirr (an Australian indigenous language), and later the word kangaroo was named by joseph banks on his first voyage in james cook.
5.jaguar
Panthera Onca (Linnaeus, 1758), also known as jaguar, is the third largest cat in existence. The weight is 70- 180 kg, and the bite force can reach 1250 lbs. This is a big cat that lives in Central and South America.
Its pattern is more like a leopard, but its whole body is closer to a tiger. Among cats, jaguars are second only to lions and tigers in size. The life of the oilfield is about 18 years. The history of artificial breeding has reached more than 20 years.

Information about animals
The giant panda is one of the most precious animals in the world. Mainly distributed in some mountainous areas of Sichuan, Gansu and Shaanxi provinces in China, the number is very rare. Belonging to the national first-class protected animals, it is called "national treasure". It is not only chosen as the emblem by the World Wildlife Federation, but also often undertakes the task of "peace ambassador". It travels across the sea with the friendship of the people of China and makes many friends, which is well received by people all over the world. Giant pandas are chubby, with round heads, thick necks, short ears, short tails and stout limbs. They are about 1.5m in length, 60-70cm in shoulder height and can weigh up to 100- 180kg. In particular, that pair of figure-eight dark circles, just like wearing a pair of sunglasses, is very attractive.

Information about animals.
Dolphins belong to Mammalia, Cetaceans, Toothed Cetaceans and Dolphins, with nearly 62 species, which are distributed in all oceans of the world. It is 1.2 ~ 4.2 meters long and weighs 23 ~ 225 kilograms. Dolphins generally have sharp mouths, and there are about 100 sharp teeth in the upper and lower jaws. They mainly feed on small fish, squid, shrimp and crab. Dolphins like to live a "collective" life, and the number ranges from a few to hundreds. Dolphin is a marine mammal with superb skills and intelligence. After training, I can play table tennis, jump in the ring of fire and so on. Dolphin's brain is the most developed among animals except humans. Human brain accounts for 2. 1% of my weight, and dolphin brain accounts for 1.7% of my weight. The dolphin's brain consists of two completely separate parts. When one part is at work, the other part gets enough rest, so it can stay awake for life. Dolphins judge the distance, direction, position, shape and even the nature of objects by echolocation. Some people do experiments, blindfold dolphins and wade in muddy water. They can catch up with the food thrown at them quickly and accurately. Dolphins not only have amazing hearing, but also superb swimming and unusual diving skills. Some tests show that the diving record of dolphins is 300 meters deep, while people can only dive 20 meters without diving suits. As for its swimming speed, it is unmatched by human beings. The speed of dolphins can reach 40 kilometers per hour, which is equivalent to the medium speed of torpedo speedboats. In the kingdom of cetaceans, the species of Dolphinidae are the largest, and there are more than 30 known species in the world. Although some species are called whales, such as killer whales and fake killer whales, they are actually members of the dolphin family. Dolphin is a clever animal. They don't run away from people like timid animals in the forest, and they don't show their teeth when they meet people like wild animals in the mountains. Dolphins always show a very docile and amiable appearance and approach people. Compared with dogs and Malays, they are sometimes even more friendly to humans. We have heard many stories about dolphins saving people from drowning, and reports about dolphins playing with people are often heard, and some stories even become sensational news. After learning and training, dolphins can even imitate the voices of some people. In 1970s, three American scientists taught two dolphins 25 words. Recently, four scientists, including Dr. Owens of the Pacific Foundation, trained two dolphins and spent three years teaching them 700 English words. However, some scientists believe that the "language" or "dialect" of animals should not be described too strangely. But dolphins do have unusual intelligence. Its brain size and quality are also among the best in the animal kingdom. At present, scientists have two different views on the intelligence of animals: one thinks that chimpanzees are the most evolved and capable of all animals; The other thinks that the intelligence and learning ability of dolphins are similar to those of apes, or even higher. Therefore, some people call dolphins "wisdom in the sea". In order to prove that dolphins can learn, as early as 1959, a man named Lili did an experiment on a dolphin. He inserted electrodes into the pleasure center and pain center of dolphins. When current stimulates the pleasure center or pain center of dolphins through electrodes, it will produce pleasure or pain. Then the dolphins are trained to touch the metal pieces on their heads and control the on-off of the current. If the electrode is inserted into the pain center of the dolphin, as long as it is trained for 20 times, the dolphin will choose to cut off the power supply to make the pain disappear. If you are a monkey, you need hundreds of trainings to learn to control the switch. This shows that dolphins have stronger learning ability in some aspects. Dolphins are friends of human beings, and they are very willing to get close to human beings. Dolphins at Mon Kemi Beach in Australia have established friendship with human beings, which has brought great joy and surprise to people. Maybe there will be more dolphins in the future, and they will establish contact with humans in more places. This wish is not an illusion: with the deepening of people's research on dolphins, we will uncover more secrets about dolphins, and then our communication with dolphins will be easier, more intimate and more friendly! Speaking of dolphins, people have heard that they have extraordinary wisdom and ability. In the aquarium, dolphins can perform various wonderful jumping movements according to the instructions of the trainer. They seem to understand the information transmitted by human beings and take action. People can't help but wonder how smart this beautiful marine animal is. So, how high is the wisdom and ability of dolphins? Is it possible for them to increase communication with humans? Starting with the structure and ecological characteristics of dolphin brain, this paper discusses its wisdom. It is difficult to determine the IQ of dolphins. Dolphins can do all kinds of difficult acrobatics, and they are obviously quite smart animals in the sea. But what is the actual intelligence of dolphins? Psychologically speaking, the word "intelligence" contains three meanings: one is the ability to adapt to various situations; The second is the ability to learn from past experience; The third is to use symbolic things such as language or symbols to engage in "the ability of abstract thinking." According to observing the behavior of wild dolphins. As well as the communication between dolphins and humans when performing acrobatics, it is speculated that dolphins have strong adaptability and learning ability; But at present, it is impossible to prove that dolphins use language or symbols for abstract thinking. However, even without scientific conclusive evidence, it cannot be considered that dolphins have no abstract thinking ability. If dolphins really have the ability of abstract thinking, how does it use this ability? To what extent? These are all interesting questions. But now, it is not easy to find the answers to these questions, because even the wisdom possessed by human beings is still unknown. Although dolphins belong to mammals like human beings, due to different living environments, there are not many opportunities for contact with each other, so human beings have very limited understanding of the potential ability of dolphins. So, what methods do humans use to study and explore the intelligence of dolphins? At present, the following two methods are mostly used: one is to calculate the potential ability of dolphins according to their anatomical characteristics; The second is to actually observe the behavior of wild dolphins and infer their wisdom from the aspects of behavioral purpose and function. The brain is no more developed than primates. From the anatomical point of view, the dolphin's brain is very developed, not only large but also heavy. The sulcus on the brain hemisphere of dolphins crisscross, forming complex folds. The number of cells and nerve cells per unit volume of cerebral cortex is very large, and the distribution of nerves is quite complicated. For example, the Atlantic bottlenose dolphin weighs 250kg, and its brain weighs about 1.500g (similar to that of an adult male). The ratio of brain weight to body weight is about 0.6, which is much lower than that of humans (1.93), but higher than that of primates such as gorillas or monkeys. As for the wrinkles formed by the sulcus in the cerebral hemisphere of dolphins, according to the research, the wrinkles of Atlantic bottlenose dolphins are even more complicated than those of humans. The surface area of their cerebral cortex is 2500 square centimeters, which is 1.5 times that of humans. The density of nerve cells in dolphin brain is almost the same as that of human or chimpanzee. In other words, dolphins have more nerve cells in their brains than humans or chimpanzees. Therefore, whether from the ratio of brain weight to body weight or the number of wrinkles in cerebral cortex, the memory ability or information processing ability of Atlantic bottlenose dolphins is comparable to that of primates. Try to understand the language of dolphins. Because the memory capacity and information processing ability of dolphin brain are equivalent to that of primates, if humans can communicate with dolphins, they should be able to obtain a lot of valuable information about marine animals and learn different expressions and thinking modes. When diving with dolphins, you will find that dolphins are quite noisy animals. According to the recorded investigation records, dolphins use ultrasonic calls with frequencies above 200-350 kHz for "echolocation", while human hearing range is between 16-20 kHz, so human beings cannot hear the ultrasonic waves emitted by dolphin echolocation. Therefore, the dolphin calls we hear in the water may be part of the low-frequency sounds that dolphins use to communicate with each other. The premise of human communication with dolphins is to understand the language of dolphins, so it is necessary to analyze the correlation between the sound and behavior of dolphins. In fact, as long as there is suitable recording equipment, the sound of dolphins can be analyzed. However, the parallel connection between sound and behavior is not easy to master. At present, people can't exactly understand the meaning of various sounds made by dolphins. In order to let humans communicate with dolphins, the second method is to let dolphins learn human language. More than 20 years ago, experts from Ocean University of America used this method to develop the intelligence of dolphins. At present, under the training of experts, dolphins have been able to learn and understand the meanings of words and complex sentences from the gestures of trainers, and make appropriate responses, but they have not yet reached the realm of free exchange of information with people. Whether studying the correlation between dolphin's voice and behavior or teaching dolphins to learn human language, the ultimate goal of mutual understanding and communication between humans and dolphins is still quite far away. The way dolphins sleep Dolphins seem to swim around forever without sleep. Dolphins are mammals. They used to live on land, but later they went back to live in water and breathed with their lungs. If they continue to sleep in water, dolphins will die because they can't breathe. Do they really have to sleep? If they can sleep, do they sleep on land or in the sea? In fact, if we can observe dolphins carefully for a period of time, we will find that they sometimes close one eye when swimming. After investigating their brain waves, it is known that one side of their brain will be asleep. That is to say, although swimming continues, the left and right brains are taking turns to rest. If we can work while sleeping like dolphins, and rest our left and right brains alternately, we can use it wholeheartedly, and we are not afraid to miss the station when sleeping in the car. Dolphins are desperate to protect their young. If the female dolphin miscarries unfortunately, in order to let it breathe, she will try her best to push the young dolphin to the surface with her nose and mouth, repeat these actions repeatedly, and even stop foraging for two days. According to people in the aquarium, once the dolphin dies, the mother dolphin will try her best to revive it, but if it lasts too long, even the mother dolphin will die of fatigue. Therefore, the calf's body must be salvaged as soon as possible. Perhaps this can prevent the mother dolphin from being too sad and restore her strength. However, it is not easy for the staff to remove the dead dolphins. Mother dolphins will protect dolphins from ships and compete with staff for endurance. Does the mother dolphin know that the baby dolphin is dead? Or do you desperately want to push the dolphins to the surface because you feel sorry for them? Or is it just animal instinct? Perhaps dolphins do have some rationality that humans can't understand, and the details are still unclear. In ancient Greece, there was a story about dolphins rescuing drowning people: On one occasion, Aleon, a famous Greek lyric poet and musician, participated in a music competition organized by a wealthy Italian businessman and won a huge prize. He returned to Corinth, Greece by boat with this wealth, but on the way, the crew were jealous of him and wanted to kill him. Before he died, he asked to play another song. The wonderful music attracted a large group of dolphins. Aleon jumped into the sea, and the dolphin carried him on his back and swam to a safe place, so Aleon escaped. This story shows that the relationship between humans and dolphins was quite good in ancient times. So what is the situation between dolphins and dolphins? 1in June, 1994, when the researchers conducted an ecological survey of dolphins in the Pacific Ocean, they observed that a dolphin was hit by a harpoon and was in a coma. Not far away, another dolphin swam over and pushed the injured species to the surface. Its sound seemed to awaken the injured dolphin in a coma. Dolphins can identify friends and enemies. When investigating wild dolphins, researchers found that dolphins were usually reluctant to approach people at first, and seemed to be aware of the existence of strange objects. However, when they realize that humans have no intention, the vigilance of dolphins gradually declines, and they can even reach a distance. They will shake their heads and observe people. As long as one of them approaches people inadvertently, the other dolphins will swim slowly. Near Chaco Bay in southern Italy, more than ten Atlantic bottlenose dolphins swim to the beach every day. These dolphins don't seem to mind human harassment. They are used to the food and bait given to them by human hands. Therefore, even wild dolphins will live in harmony with human beings if given the right opportunities. But human beings have to get rid of the prejudice of "the spirit of everything" and stay in the world of dolphins. Find other ways to communicate with dolphins. Jack the genius navigator has a unique dolphin monument in Wellington, New Zealand, which reads "Jack the genius navigator". 187 1 year, the sailboat "burini" passed through Cork Strait, New Zealand, and was trapped in the "Death Canyon" for a whole day due to sudden weather changes. It was about to be destroyed, and the desperate captain crossed his chest feebly. Suddenly, his eyes lit up, and a big silver-gray dolphin jumped out of the stormy waves, looking back and forward from time to time, as if to say, "Please rest assured, my friend, I know how to go out and get rid of death." The captain seemed to see the lighthouse during the night flight and ordered to follow the dolphins without thinking. The great dolphins finally led burini people out of the land of terror. Since then, miracles have appeared. This silver-gray dolphin has been wandering around the strait, leading the passing ships year after year. Whenever a boat comes, it will always jump out of the water and wave its tail fin to welcome it. But it bypassed the reef and escaped the turbulence, which enabled the ship to escape. The crew affectionately called it "Jack". 19 12 years, Jack ended his 40-year career as a volunteer pilot and passed away quietly. The local people attached to it, and divers found its body, covered it with a national flag, held a funeral for it, and later carved a bronze statue for it. Dolphins pay attention to division of labor in hunting. Dolphins move in groups in the process of hunting. Not only that, na-ture website reported that a recent study on the coast of Florida showed that each dolphin has its own clear division of labor in hunting. Cooperative hunting is found in many animal groups, such as chimpanzees. But each individual has his own specific job in the group, just like in a football team, each player has his own division of labor, which is rare in animal groups. American researchers observed two groups of dolphins, one consisting of three and the other consisting of two to six. The researchers identified each dolphin by marking their fins and observed their 60 hunting activities. It is found that in the process of collective hunting, one of the two groups of dolphins always plays the role of "driver", while the other group of dolphins plays the role of "obstacle". The "driver" dolphins will drive the small fish around them into the encirclement formed by the obstacle dolphins. This kind of individual division of labor in hunting has only been found in African lionesses in the past. A lioness waits in the center of the whole hunting scene, while other lionesses attack prey from all directions. Regarding the special division of labor among dolphins discovered this time, the researchers said that it is still uncertain whether this special hunting method exists in all dolphins or only in a certain area. Why do dolphins swim fast? A good figure is a prerequisite for swimming fast. But even the best figure, in nature, if you want to be a swimmer, there are still many details to be perfected. When animals swim in the water, they usually cause some small eddies. These small eddies affect the swimming speed of animals. Dolphins and sharks have different ways to solve this problem. On the dolphin's body, the slippery skin is not tight, but elastic. Dolphins shrink their skin when swimming, thus forming many small pits on their skin, in which water is stored. In this way, a "water cover" is formed around their bodies. When the dolphin swims fast, the "water cover" covers its body and moves with it. With the help of this water protective layer, dolphins swim with little friction and will not cause whirlpool. Dolphin rescue has a long history 1949. The wife of a lawyer in Florida, USA, disclosed her strange experience of being rescued from drowning at sea in Natural History magazine: when she was swimming at a beach, she suddenly fell into an underwater undercurrent, and rows of turbulent waves came at her. Just when she was about to go into a coma, a dolphin swam quickly, gave her a sharp push with its sharp beak, and then pushed her several times until she was pushed into shallow water. After waking up, the woman looked around to see who saved herself. However, there is no one on the beach, only a dolphin is playing in the water not far from the shore. In recent years, there are more and more similar reports, which shows that dolphins were never invented by people. Dolphins will not only push drowning people to the shore, but also come forward to rescue sharks when they eat people. 1959 in the summer, the passenger ship "Rio Arteiro" crashed in the Caribbean, and many passengers struggled in the rough sea. Unexpectedly, it never rains but it pours. A large group of sharks came around and everyone would be buried in the belly of the fish. At this critical juncture, groups of dolphins suddenly appeared like "heavenly soldiers and heavenly generals", pouncing on greedy sharks, driving away demons in the sea and turning passengers in distress into safety. Helping the weak is an instinct. Dolphins are always an animal that helps the poor. When people are in danger in water, they often get its help. Dolphins have also won the reputation of "lifeguards at sea", and many countries have promulgated laws and regulations to protect dolphins. So why do dolphins save people? Before people fully understood dolphins, they were always thought to be sent by God to protect human beings. Due to the progress of science, the understanding of dolphins is further deepened, and its mystery is gradually uncovered. Zoologists have found that dolphins are not limited to humans. They will rescue their sick companions. During the period of 1959, American zoologist De Herb Nale and others saw two dolphins swimming towards a dolphin injured by explosives, trying to rescue their companions. Dolphins also help newborn dolphins, and sometimes they seem blind. In an ocean park, a little dolphin died at birth, but it was pushed out of the water by its mother. In fact, almost all objects that do not actively move in the water will attract the attention and great enthusiasm of dolphins and become their "rescue" objects. Some people have done many experiments, and the results show that dolphins will do the same thing to anything floating in front of them, whether it is a dead turtle, an old air cushion, a lifebuoy or a wooden board. 1955, a dolphin rescued its old enemy, a young tiger shark, which was 1.5 meters long, and lifted it out of the water for eight consecutive days. As a result, this unlucky little shark finally lost his life. Accordingly, marine zoologists believe that the life-saving virtue of dolphins comes from their "caring nature" for children. It turns out that dolphins are mammals that breathe with their lungs. They can dive into the water when swimming, but they have to put their heads out of the sea to breathe every once in a while, otherwise they will suffocate. Therefore, for newborn dolphins, the most important thing is to reach the surface as soon as possible, but if there is an accident, the dolphin mother's care behavior will happen. She gently lifts the dolphin with her beak, or holds the pectoral fin of the dolphin with her teeth to make it surface until the dolphin can breathe on its own. This caring behavior is the instinctive behavior of dolphins and all whales. This instinct is formed in the process of long-term natural selection, which is very necessary for protecting the same kind and continuing the race. Because this behavior is independent of the object, once the dolphin meets the drowning person and mistakenly thinks it is a floating object, it will also have the same push-pull reaction, thus saving people. In other words, it is a coincidence that the inherent behavior of dolphins coincides with the exciting phenomenon of "saving people". Some scientists believe that it is a simplification to attribute the dolphin's rescue behavior to an animal's instinct, and its root is to underestimate the wisdom of animals. Oceanographers believe that dolphins have the same learning ability as humans, even slightly better than chimpanzees, and are known as "wise men" in the ocean. Studies show that dolphins are far superior to chimpanzees in both absolute and relative brain weight, and learning ability is closely related to intellectual development. Some people think that dolphins have larger brain capacity than chimpanzees and are obviously animals with high IQ and thinking ability. Its "feat" of saving people is completely a conscious act. Because in most cases, dolphins will push people to the shore, not the sea. At the beginning of the 20th century, near the Atlantic Ocean in Mauritania, there was a poor fishing village, El Mahara. Dolphins in the Atlantic seem to know that people are suffering from hunger, and often drive a large number of fish from the high seas to the port to help fishermen cast nets to catch fish. In addition, anecdotes similar to dolphins helping people fish have also been reported in Australia, Myanmar, South America and other places. What is the reason why dolphins are so single-minded to humans? In front of sharks, dolphins are crazy killing gods. It is easy to attack humans, but there is no record of dolphins hurting people. The most incomprehensible thing is that even if someone kills a dolphin, the other dolphins present just stand by and never answer blows with blows. For dolphins with strong cooperative spirit, this kind of performance really puzzles zoologists. Dolphins also have names. According to a report by the Russian News Network on May 24th, scientists from the University of St Andrews in the United States recently concluded that every dolphin in a social state has its own name, and dolphins in the same group can also distinguish each other's "names". The scientists chose the research site on the Florida coast. During the research, experts recorded and analyzed the sounds made by social dolphins. After that, they separated all the sound signals that can indicate the identity of a specific dolphin, and only kept the frequency characteristics of these sounds. It is reported that by comparing with the sounds made by people, researchers have separated stress and other characteristics related to "dialogue" from the sounds made by dolphins. During the experiment, the researchers divided the dolphins in the same group into two groups and extracted the sounds made by one group. Later, by playing these sounds to another group of dolphins, people were surprised to find that they actually responded positively to the voices of their "relatives". Vincent Janick, a scientist who participated in the research, said: "We recorded some dolphin calls in the dry season and input them into the computer to synthesize similar sounds artificially. After that, we played these recordings to the dolphins and observed their reactions. The results show that dolphins can completely tell who made these sounds. " Based on these observations, scientists have come to the conclusion that dolphins not only have their own names, but also can distinguish their companions according to these names, rather than relying solely on sound. Janick pointed out: "Now we know that dolphins actually have their own names just like us." Scientists believe that this identification method is very necessary for dolphins-because underwater sounds are easily distorted, and companions can only be identified through more complex sound combinations. It is reported that 9 of the 14 dolphins who participated in the experiment responded to the "names" of their relatives. However, scientists still don't know why the other five dolphins didn't make any corresponding movements. Maybe they don't want to see their relatives. Janick said that this discovery is significant because it shows that dolphins have some behaviors similar to ours. Dolphins live and act in the wild. Dolphins catch prey with their teeth. They have 90 to/kloc-0.00 teeth, but they don't chew. Instead, they swallowed the whole fish. Like whales, dolphins breathe through blowholes in their heads. They swim out of the water and exhale. They will take a deep breath before diving into the water again.
