12 species of endangered animals in the world
The twelve most endangered animals in the world are 1 and the northern white rhinoceros. Garamba National Park in Congo has less than 25 northern white rhinos left in the world, and it is possible that the northern white rhinos will completely disappear from the earth. Guaramba National Park is located on the border between the Democratic Republic of Congo and China. Because the original intention of building the park was to apply for becoming one of the world natural heritages, the builders spared no effort to enclose a large area of grassland and Woods. Guaramba National Park has many rare animals in the world, such as jungle elephants, bison and chimpanzees. Of course, the most precious animal is the northern white rhinoceros, whose number is less than 25. There are great genetic differences between northern white rhinoceros and southern African white rhinoceros. They once multiplied in Uganda, but gradually disappeared due to the neglect of protection by the local government. In Guaramba National Park, their number reached 35 in the late 1980s and 30 in April 2003. Then six were killed and four were born. Last month, two elephants were hunted and nearly 1000 elephants were killed. Although the trade of ivory rhinoceros horn is banned all over the world, the black market is still in full swing. Yemen has a special rhinoceros horn market, where daggers with rhinoceros horns as handles are the focus of many buyers and sellers, and also a symbol of status. 2. Baiji Dolphin: alias Baiji Dolphin and Baiji Dolphin, belonging to Cetaceae, with the scientific name LipotesvexilliferMiller, belonging to Cetacea and Baiji Dolphin. The distinctive feature is that the snout is long and narrow, about 300 mm long. The forehead is round and high. The dorsal fin is triangular, located in 3/5 of the body, and has a low skin ridge connected with the caudal fin. There is a breathing hole on the left side of the head that can be opened and closed freely. The caudal fin is horizontal, concave to the edge and crescent-shaped. Up to now, the largest female found is 253 cm long and weighs 237 kg. The largest male is 2 16 cm long and weighs 125 kg. The population of baiji dolphin is very small, which is a rare aquatic animal in China and needs to be protected urgently. Produced in the middle and lower reaches of the Yangtze River in the main streams of Hubei, Anhui and Jiangsu. Like to live in groups, especially in the spring mating season, group behavior is more obvious. Generally, each group has 2-6 heads. It has a wide range of activities, but it requires high hydrological conditions. It often stays in a fixed area for a period of time, and then moves to another area after the hydrological conditions change. Feed on fish. Baiji dolphins breed every two years, each offspring 1, and the body length is about 80 cm at birth. They have lived in the Yangtze River for about 25 million years and are called "living fossils". Because of its small number, it is listed as a national first-class protected wild animal. In addition, in 1980, a male baiji named "Qiqi" was captured and raised in the Institute of Hydrobiology, Chinese Academy of Sciences. This is the only captive-bred baiji in the world. It is hoped that a female individual can pair with it to breed, but a female baiji that was raised died soon, which has not been realized so far. July 2002 14 "Qiqi" Qi Qi was 2.07 meters long and weighed 98.5 kilograms, about 25 years old. The protection of baiji dolphin has become a big problem to save endangered wild animals in China. Although the research on giant panda cloning in China has started, there are still many technical difficulties in cloning baiji, one of the three endangered animals in China, which enjoys the reputation of "giant panda in water". 3. Sumatran tiger: The Sumatran tiger living on Sumatra Island in Indonesia is one of the smallest tiger species in the world. They have lived in the rain forest on the island for generations. As early as the beginning of the last century, the family of Sumatran tigers was once very prosperous. However, under the wanton killing of human beings, the number of Sumatran tigers has dropped sharply. According to the latest survey of the World Wildlife Fund, from 1998 to 2002, at least 50 Sumatran tigers were killed by poachers' guns every year, while a statistic made by 1999 showed that there were only 400 to 500 Sumatran tigers living in Indonesia at that time. Officials of the World Animal Fund said that the current large-scale poaching in Indonesia is caused by the demand of its domestic market. In the Indonesian market, the tiger skin of Sumatra tiger is a cash cow for many unscrupulous businessmen to seek high profits. A complete tiger skin can be sold for two thousand yuan. The disappearance of rainforest habitat also threatens the survival of Sumatran tigers. According to the World Bank's estimation, according to the current situation, the rainforest reserve on Sumatra Island will all disappear in 2005. Despite this, the world's largest paper makers are still devouring the rainforest on Sumatra at the rate of thousands of hectares per month. On the one hand, illegal hunting is getting worse, and on the other hand, the living space is shrinking. Faced with such a difficult living environment, how can people not worry about the fate of the Sumatran tiger? As a result, some people think of the Bali tiger and the Java tiger, which became extinct in the 1930s and 1980s. The fate of the Sumatran tiger has attracted great attention from animal protection organizations. Recently, at the International Trade Conference on Endangered Wild Animals and Plants held in Geneva, Switzerland, experts called for strengthening the protection of Sumatran tigers, cracking down on illegal hunting and protecting the endangered Sumatran tigers. After all, Sumatra tiger is not only the wealth of Indonesia, but also the wealth of the whole world. 4. Monk seals: There are many kinds of seals in the world, which are the largest family of marine pteropods. However, with the passage of time, the seal family is shrinking, and now there are only 19 species left. Just before the middle of the 20th century, a monk seal lived on many islands in the Caribbean. Caribbean monk seals are slightly larger than ordinary seals, with a body length of 2.6 ~ 2.8m and an average weight of 400kg. It has no spots like ordinary seals, and it is brownish gray or grayish brown. Its back midline is black, its snout is short and wide, and its forehead is high and round. Monk seals, like other seals, have good hearing without external ears. It also has a pair of keen eyes, which can see not only things in the water, but also objects in the air. Monk seals are more suitable for living in water than sea lions and walruses. If its hind legs can't bend forward, it is very important to move in the water. Also, its body is smooth and almost streamlined, which is very suitable for fast swimming and diving in the water. Sharp vision and hearing combined with dexterity in water make it easier to catch all kinds of fish. Once on land, its movements are very clumsy and ridiculous. The limbs that are good at swimming can only play an auxiliary role and have to crawl slowly. Clumsiness on land has also become one of the reasons for their future extinction. Monk seals are very vigilant during breastfeeding. Once they find danger, they will immediately push the baby seal into the water and then dive by themselves. If a baby seal is caught, the big seal will rob the baby seal regardless of his own safety. If people take away baby seals, big seals will attack people angrily. However, in the end, they failed to escape from the palm of human hands. Introduction: Seal is an ancient and rare seal, and it is also the only seal in the world that has lived in tropical waters all its life. Monk seals have multiplied in the Caribbean and Mediterranean in history. Today, due to the indiscriminate killing of human beings, monk seals are hard to find in other parts of the world, and only a small part exists in the northern Hawaiian Islands. Unlike seals who like to live in cold water, monk seals like tropical warm seawater. In the middle of the rippling Pacific Ocean, there is a jade-like island called Ni Hao Island, which is a pasture island. Monk seals mainly thrive on the beaches of this island. This island is private. In order to protect the environment on the island, the island owners generally don't allow researchers to go to the island, so no one knows how many monk seals there are on the island. 5. Orinoco crocodiles: There are four kinds of crocodiles threatened by overfishing and environmental pollution in the world, one of which is the Orinoco crocodiles living in Venezuela. It is the largest crocodile in America and a treasure among Venezuelan animals. Over the years, the relevant units in Venezuela have taken various measures to protect the endangered Orinoco crocodiles and achieved results. 1990, the Ministry of Environment and non-governmental organizations initiated and formulated a plan to protect the Orinocidaceae crocodile, and increased the number of this precious animal through artificial protection and reproduction. Because it is impossible to breed in large quantities in the natural environment. This crocodile is only found in Venezuela and Colombia, with an initial estimate of only 250. After 10 years of conservation work, 2 150 alligators of Orinoco River have been bred and released to nature, of which 1400 are in Appler. It is estimated that there are 3,000 crocodiles over one year old now, and there may be 5,000 crocodiles. In order to protect crocodiles, authorities have established three crocodile farms in Kochdes and Potugesa, where adult crocodiles can breed and then be artificially fed for one year. When the crocodile grows to 80 cm, it will be put back into the river at the beginning of the rainy season. In order to follow up, technicians tied a ring on the crocodile's leg and marked it on the weighing scale. The activities to protect crocodiles have received strong support from relevant departments and private enterprises. Feeding an adult crocodile requires 6.5438+0.5 million bolivar per month. It eats high-cost foods such as horse meat and fish, and the farm also adds vitamins to the food to enhance the crocodile's physique. 90% of the farm's budget is used to buy crocodile food. The Ministry of Environment is seeking international assistance in order to increase funds and better protect crocodiles in Orinoco River. A biologist holds several one-day-old Orinoco crocodiles in Aprere Biological Reserve, 752km from Caracas, Venezuela. As part of the plan to protect Orinocidae crocodiles, more than 65,438+030 crocodiles of one to two years old born in cages were released into nature. 6. The smallest monkey in the world. Madagascar island in the Indian Ocean in southeastern Africa is called "Fox and Monkey Island". There are more than 20 species of lemurs on the island, mainly big lemurs, small lemurs, mouse lemurs, gray lemurs, silk lemurs, velvet lemurs and ring-tailed lemurs. The Latin name of lemur means "ghost". They haunt tropical forests and like to make noise. Different species have great differences in appearance, size and habits. The big lemur is the "giant" among the existing lemurs. It is about 1.2 meters long and has a strong body. The top of the head and waist are white, and the rest are black and white. The little lemur is only 20 cm, chubby, with big eyes and a slightly shorter tail than its body. In the hot and dry season, it has the habit of sleeping in summer, when it relies on the fat stored in its tail to maintain its life. The body of a mouse lemur is similar to that of a mouse. It looks like a mouse, with a long and prominent nose and a wet nose, like a dog's nose. Gray lemurs are similar in shape and length to marmosets. They have a round face, a pointed mouth and very big front teeth on their chins. They live in the forests of eastern Madagascar. Only in the early morning and dusk can they see males and females moving in the trees in pairs, but it is difficult to see them living together. Lemurs are bigger than cats, covered with pure white silky fur, and a long tail is beautiful and flexible. It turns out that lemurs have a hairy tail and a white scarf around their heads, so they are very agile. In addition, Cayo Santiago Island near the coast of Torico in the Caribbean, Gushan Island in Fuxian Lake in Yunnan, and Nanwan Macaque Island in Lingshui County, Hainan are all famous macaque islands, especially Nanwan Macaque Island in Lingshui County, Hainan, which is close to the South China Sea. Macaques are also called "little monkeys" and "rhesus monkeys". Their hair is grayish brown, orange and shiny below the chest, dark gray on the chest, abdomen and legs, bare face and ears, and red buttocks. It takes only 10 minutes by yacht from Xincun Port, Lingshui County, Hainan Province to reach Macaque Island in Nanwan Peninsula. Macaque Island was originally named Nanwan Monkey Island. The South Bay Peninsula is surrounded by the sea on three sides, and only one side is connected with the land. 65,438+02 Mountains of different sizes are undulating, facing each other across the sea, like an island. Because there are many macaque groups living here, people call it "Macaque Island". This is a veritable monkey paradise. The island covers an area of 9 square kilometers with a mountain length of 15 kilometers. There is a small mountain peak in the middle, which is divided into two parts by a river beach with a width of 50 meters, showing layers of mountains and gullies. When I came to the tourist area, a vivid picture was presented to me. There are macaques everywhere on the mountain, some at the top of the mountain, some in the ravine, some alone on a hill, and some scattered in two or three groups on a hill. Every group of monkeys has a king and two kings. There is a monkey-watching pavilion on the mountain, where visitors can watch the wonderful performances of macaques and feel a kind of wild interest that is obviously different from ordinary parks. Some macaques drink water by the well, which reminds people of "monkeys fishing for the moon"; Some jump between two trees, and some somersault on the ground, which makes people seem to be watching the wonderful performance of "Sun Shengda" in "Huaguoshan" ... sRidleyTurtle of 7.L. Kemp is the only animal with an increasing number among the 65,438+02 most endangered animals in the world. It takes 1 1-35 years to grow. 8. Only 250-700 Orinocidaceae crocodiles live in the wild. Mainly in Cuba and Venezuela. 9. kitt is Hog-noise Bat in Thailand, a pig-nosed bat living in limestone caves along the Guayenoi River in Beibi Province, Thailand, has a head length of 2.9 cm, a wing width of 13 cm, a weight of 1.7 g .. 10, and a Hawaiian snail (Achatinella). In 1990, ornithologists looking for this bird only found a surviving male bird, living in the distant northeast of Brazil. At present, about 3 1 bird captured by humans is the only hope for this bird to survive. Macaw is a parakeet living in tropical America, with colorful feathers, but this popular parrot may be extinct, at least the wild one no longer exists. According to biologists, there is a blue wild macaw, the last one of its kind, but it has been missing for a long time and may be in trouble. Biologists have been paying close attention to this parrot. It is 19 years old, but they haven't seen it again in the past two months. It may become a delicacy for eagles or be captured by poachers. 12, Sussalvanius: the smallest pig in the world, a kind of wild boar, mainly living in northeast India. It is 60 cm long and 25 cm high, and the adult pig is less than 10 kg. It used to be abundant in the Himalayas, but now only Manas National Park in Assa, India has a small amount. Its genes are not much different from those of domestic pigs.
