What are the endangered wild animals?

It belongs to Artiodactyla, commonly known as the four elephants. It lives in swamp areas and feeds on grass and aquatic plants. It was raised in Nanyuan, Beijing before 1894. Since then, only a few of its wild species have become extinct. 1985 and then shipped back to the UK for stocking. Distribution: It was once widely distributed in all parts of China, and then the wild species became extinct. Beijing Zoo 1 Indochina Peninsula and China's southeast coastal areas (including Myanmar, Vietnam, Laos, Cambodia, Thailand and China's southeast coastal areas, Hong Kong and Hainan Island). 7 Central America (located between North America and South America, including Guatemala, Belize, Honduras, El Salvador, Nicaragua, Costa Rica, Panama, Bahamas, Cuba, Haiti, Jamaica, Dominica, Antigua and Barbuda, Saint Vincent and the Grenadines, Saint Lucia, Barbados, Grenada, Trinidad and Tobago and other countries and regions) is located in.

panda

Living in arrow bamboo forest, afraid of cold and summer, sexually lonely, male and female separated, able to swim, good at climbing trees, living in tree holes and crevices, fond of eating bamboo, fruits and animal bones, gentle in temperament, weak in self-defense, often hurt by natural enemies, distributed in western and northern Sichuan, China.

Sichuan, Shaanxi and Gansu in China. Endemic to China, the wild population is less than 1000.

However, it was raised artificially at about 100.

Giant pandas (also known as giant pandas) live in alpine bamboo forests at an altitude of 2000-3500 meters. I live alone, rest day and night, and have no settlement. Poor eyesight and hearing, good sense of smell, awkward posture, good at climbing and swimming. Feed on bamboo leaves, bamboo shoots and bamboo poles. Eat small animals and bird eggs occasionally. The breeding season is in spring, the gestation period is 80- 160 days, and each fetus is 1-2. Sexually mature at the age of 5-7, with a life span of 25- 30 years. Beijing Zoo started the breeding exhibition on 1955, 1963 successfully propagated, 1978 artificially propagated, 1993 totally propagated, 1999 artificially assisted propagated twins.

It is a first-class protected animal in China.

China/Chinese alligator

It belongs to reptiles, also known as catfish.

Alias Eriocheir sinensis, Longtu and Zhupolong belong to Eriocheir sinensis, and the scientific name is alligator sinensis.

The total length of an adult fish can reach about 2 meters, and the tail length is similar to the body length. The head is flat, the nose and mouth are long, and the external nostril is located in the nose and mouth with a flap. The body is covered with a piece of leather armor, and the abdominal armor is soft; The nail plates are nearly rectangular and neatly arranged; There are two rows of nail plates protruding to form two ridges running through the whole body. The limbs are short and thick, with webbed toes and claws. The back of the body is grayish brown, the front of the abdomen is gray, and it is grayish yellow from the anus to the back. Flat tail. Newborn crocodiles are black with yellow stripes.

He lives by digging holes in rivers and lakes, and he is fierce, feeding on all kinds of mammals, birds, reptiles, amphibians and crustaceans. Mating in June, laying eggs in July and August, each nest can lay more than 20 eggs. The eggs are laid in the grass, covered with weeds, and the female crocodiles stay by and hatch at natural temperature. The incubation period is about 60 days. Have the habit of hibernating.

Produced at the junction of Anhui, Zhejiang and Jiangsu. Chinese alligator is a unique relic species in China, which has many physiological characteristics, and the discontinuity of distribution also illustrates this point. In order to explore the mystery of the Chinese alligator, China established the Chinese alligator reserve and the Chinese alligator breeding research center.

It belongs to the national first-class protected animals.

salamander

Amphibia, also known as giant salamander, is the largest amphibian in the world. It is endemic to China, inhabits mountain streams, moves at night, preys on fish, shrimp and insects, and is fertilized in vitro. It is widely distributed in China, mainly in Central China and South China. Crying baby

The giant salamander, also known as the giant salamander, belongs to the amphioxus family, and its scientific name is giant salamander.

The giant salamander is the largest species in the existing order, and its longest can exceed 1 m. The head is flat and blunt, the mouth is big, the eyes are underdeveloped, and there are no eyelids. The front of the body is flat, and the tail gradually turns to the side. There are obvious skin folds on both sides of the body, short and flat limbs, and slightly webbed fingers and toes. The tail is round and has fins up and down. The body surface is smooth and covered with mucus. The back of the body is mixed with brown and red, and the ventral color is lighter.

Giant salamanders live in clear streams in mountainous areas, generally hiding in the gaps of mountain streams, and the caves are below the water surface. Laying eggs in July-August every year, with more than 300 eggs per tail. Male salamanders wrap their eggs on their backs and hatch after 2-3 weeks.

Giant salamander is an endemic species in China, and it is commonly called "giant salamander" because its cry is like a baby crying. The heart structure of giant salamander is special, and some reptilian characteristics have appeared, which has important research value. Because the meat is delicious, it is regarded as a treasure and has been killed. Resources have been severely damaged and need to be protected.

Giant salamanders are mainly produced in North China, Central China, South China and Southwest China. I also occasionally see it in our city. Its individual is not big, and it is often mistaken for an ordinary fish. In the summer of 200 1 year, a giant salamander only a few centimeters long was found by the public and sold at a stall in Xikou town of our city. After the purchase, it was sent to the relevant departments for signature, and now it is kept in the water hall of Tengtou Village.

The giant salamander belongs to the national second-class protected animal.

golden monkey

Primates, with long golden hair on their shoulders, live in 3000-meter alpine forests, live in arboreal groups and feed on wild fruits, buds and bamboo shoots. They are rare monkeys in China.

The scientific name of golden monkey is Rhinopithecus roxellanae, and the English name is snub-nosed monkey/golden monkey. Golden monkey is an endemic animal in China, which belongs to the national first-class protected animal. China golden monkeys include Sichuan, Yunnan and Guizhou. Yunnan golden monkeys live in the snow-capped mountains and fir forests in remote Yunnan and Tibet, with only one thousand in number. Guizhou golden monkey only exists in Fan Jing, Guizhou, and the number is only over 700. Everyone is familiar with Sichuan golden monkey. Sichuan golden monkey, distributed in Sichuan, Shaanxi, Hubei and Gansu, lives in the deep mountains, in groups, with golden cloaks on their backs, climbing trees, jumping and prancing. The golden monkey has been rented abroad for many times, which has achieved good exhibition effect and great sensation effect.

White fin dolphin

Mammals inhabit Dongting Lake and the middle and lower reaches of the Yangtze River. During the flood season, the water level rises, swarms swim into Dongting Lake and its vicinity to breed, and the water level drops back to the Yangtze River, mostly in the deep layer. At dawn and dusk, it preys on fish near shallow water and is on the verge of extinction.

White-fin dolphin is commonly known as white fin, white clip and hippo. It belongs to mammals, cetaceans and baiji. Its distribution is limited to the middle and lower reaches of the Yangtze River, especially in the Yangtze River section of Hunan, Hubei, Anhui and Jiangsu below Shashi, Hubei.

Baiji dolphin is a rare aquatic mammal endemic to China. It is a valuable material for studying cetacean evolution and biological evolution. It has a developed brain and is an intelligent animal. It has special functions such as "echolocation" and sonar. Streamlined figure, rich subcutaneous fat and fast swimming, these structures have important scientific value in bionics.

Baiji dolphin is spindle-shaped. The snout is extremely long and narrow, and the maxilla and mandible are almost the same length and slightly upturned. The body length is six times that of a kiss. Body color: the back is bluish gray and the abdomen is white. There are semicircular white wide lines on both sides of the neck, behind the ear hole and above the flippers, and there are two half-moon white wide lines on the tail side above the anus.

Baiji dolphins like to move in the mainstream areas of rivers far from the shore, and belong to hydrophobic dolphins. There is a habit of clustering in action, often moving in the middle of the river in groups of three or five, and occasionally entering the confluence of lakes, tributaries and the main stream of the Yangtze River. Baiji dolphin breathes with its lungs and comes out of the water for air every minute or two. When breathing, the head always comes out of the water first, sometimes spraying water, and making a sound when breathing out of the water. The weather is sultry, and when the rainstorm comes, it will come out of the water frequently and fall together. The masses call it "Baiji Dolphin Worship River".

Baiji dolphin is a carnivore with poor eyesight. It finds food through its own ultrasonic signal and then suddenly swallows it. Their feeding habits are mainly fish, and they often feed in shallows, bifurcated streams and tributaries. Its food intake is very large, and the general food intake can account for 10% ~ 12% of the body weight.

The female is 6 years old and the male is 4 years old. The reproductive mating period is from April to June, the pregnancy is about 9 months, and the baby is delivered in the river in February of the following year. Female dolphins only give birth to 1 baby every year, each baby 1 baby, and occasionally give birth to twins. Newborn dolphins grow up by feeding their mothers' milk and act with the group.

Great changes have taken place in the ecological environment of the Yangtze River after the completion of Gezhouba and Three Gorges Dam. The development of shipping industry, river regulation, the increase of motorboats, water pollution, siltation of rivers and lakes, the use of harmful fishing gear and harmful fishing methods, etc. , a serious threat to the ethnic continuation of the baiji dolphin. According to the measured statistics, the resources of Yangtze baiji dolphin are less than 100, far less than the national treasure giant panda. In order to prevent the extinction of the baiji in nature, the state has listed it as a first-class protected animal, and designated the Swan Island Ancient Road in the Yangtze River and Tongling section in Anhui Province as nature reserves to protect and multiply baiji resources and save endangered species.

Siberian tiger

Also known as Siberian tiger, it is an endangered species in the world, mainly distributed in northeast China and Siberia. Due to excessive deforestation in China, the ecological environment on which Siberian tigers depend for survival has been seriously damaged, and the population number has dropped sharply. According to the recent field investigation by the international joint investigation team, the number of wild Siberian tigers in China is less than 20.
