What are the endangered animals in the world? Let’s talk about them in detail.

The world’s twelve most endangered animals: 1. Northern white rhino (Sumatran rhinocerous). Congo’s Garamba National Park has less than 25 northern white rhinos left in the world. Rhinoceros may disappear completely from the earth. Gualamba National Park is located on the border of the Democratic Republic of the Congo. Since the original intention of establishing the park was to apply for the park to become one of the world natural heritage sites, the builders spared no effort , enclosing a large area of ??grassland and woods. Gualamba National Park is home to many rare animals in the world, such as jungle elephants, bison, and chimpanzees. Of course, the most precious animals are the northern white rhinos, which number less than 25. There are great genetic differences between the northern white rhinoceros and the white rhinoceros in southern Africa. They once bred in large numbers in Uganda, but gradually disappeared due to the neglect of protection by the local government. In Gualamba National Park, their number once The number reached 35 in the late 1980s, and 30 in April 2003. Later, 6 were killed and 4 were born. Last month, 2 more were hunted, and there were nearly 1,000 more. Elephants were killed. Although the trade in ivory and rhino horns is banned globally, the black market is still booming. There is a special rhino horn market in Yemen, where daggers with handles made of rhino horn are among the many buyers and sellers. The focus of attention is a symbol of status. 2. Baiji: Also known as Baiji and Baiji, it belongs to the beaked dolphin family. Its scientific name is Lipotesvexillifer Miller, which belongs to the order Cetacea and the family Baiji. The identification characteristics are: long and narrow snout process, long About 300 mm. The forehead is round and raised. The dorsal fin is triangular, located 3/5 of the body, with a low skin ridge connected to the caudal fin. There is a breathing hole that can open and close freely on the left side of the head. The caudal fin is horizontal and towards the edge. It is concave and crescent-shaped. So far, the largest female found is 253 centimeters long and weighs 237 kilograms; the largest male is 216 centimeters long and weighs 125 kilograms. The Baiji dolphin population is very small and it is a rare aquatic animal unique to China. This species needs to be protected urgently. It is produced in the main streams of the Hubei, Anhui and Jiangsu sections of the middle and lower reaches of the Yangtze River. It likes to live in groups, especially during the spring mating season, the group behavior is more obvious. Each group usually has 2 to 6 individuals. Its activity range is wide, However, it has high requirements on hydrological conditions. It often stays in a fixed area for a period of time. After the hydrological conditions change, it moves to another area. It feeds on fish. Baiji dolphins breed once every two years, with one calf per litter. They are about 80 centimeters long when they are born. They have lived in the Yangtze River for about 25 million years and are known as "living fossils". Due to their extremely small number, they are listed as first-level protected wild animals in China. In addition, a male white-tip dolphin was captured in 1980. It was raised at the Institute of Hydrobiology, Chinese Academy of Sciences, and was named "Qiqi". It was the only artificially bred baiji dolphin in the world. It was originally hoped that a female individual would be paired with it for breeding, but the female baiji dolphin they raised soon died. He died on July 14, 2002, and has not been able to do so. "Qiqi" died of old age on July 14, 2002. Before his death, Qiqi was 2.07 meters long, weighed 98.5 kilograms, and was about 25 years old. Protection of Baiji Dolphins It has become a major issue in the rescue of endangered wild animals in China. Although China's research on giant panda cloning has begun, for the Baiji dolphin, which is also listed as one of the three most endangered animals in China and enjoys the reputation of "Giant Panda in the Water", There are still many technical difficulties in cloning. 3. Sumatran tiger: The Sumatran tiger living on the Indonesian island of Sumatra is one of the smallest tiger species in the world. They have lived in the rainforest on the island for generations. As early as the beginning of the last century, The Sumatran tiger family was once very prosperous. However, due to wanton hunting by humans, the number of Sumatran tigers has decreased sharply. According to the latest survey by the World Wildlife Fund, from 1998 to 2002, at least 50 Sumatran tigers were killed every year. died at the hands of poachers, and a 1999 statistics showed that there were only 400 to 500 Sumatran tigers living in Indonesia at that time. Officials from the World Animal Fund said that Indonesia’s current large-scale The poaching behavior is caused by the domestic market demand. In the Indonesian market, Sumatran tiger skins are a cash cow for many unscrupulous traders to make high profits. A complete tiger skin can be sold for two thousand US dollars. The disappearance of rainforest habitat also threatens the survival of Sumatran tigers. According to the world

Banks estimate that under current conditions, all rainforest reserves on Sumatra will disappear by 2005. Despite this, several of the world's largest paper manufacturers are still devouring thousands of hectares of rainforest on Sumatra every month. . On one side is the intensifying illegal hunting, on the other side is the shrinking living space. Faced with such a difficult living environment, how can people not worry about the fate of the Sumatran tiger? So, some people thought of the Bali tiger and the Javan tiger. The fate of these two Asian tigers that became extinct in the 1930s and 1980s. The Sumatran tiger has attracted great attention from animal protection organizations. At the International Conference on Trade in Endangered Wild Fauna and Flora held in Geneva, Switzerland, experts recently There are calls for increasing the protection of Sumatran tigers, combating illegal hunting, and protecting Sumatran tigers that are on the verge of extinction. After all, Sumatran tigers are not only the wealth of Indonesia, but also the wealth of the world. 4. Monk Seals: There were many in the world. They are the largest family of pinniped marine animals. However, as time goes by, the seal family has shrunk, and now there are only 19 species left. Just before the middle of the 20th century, on many islands in the Caribbean There is also a kind of monk seal living on the island. The Caribbean monk seal is slightly larger than the ordinary seal, with a body length of 2.6 to 2.8 meters and an average weight of up to 400 kilograms. It does not have spots like ordinary seals and is brown-gray or gray. It is brown, with a very dark midline on its back, a short and wide snout, and a high and rounded forehead. Like other seals, the monk seal has no external ears, but has good hearing ability. It also has a pair of sharp eyes, which can not only see the water clearly It can also see objects in the air clearly. The shape of the monk seal is more suitable for living in the water than the sea lion and walrus. For example, its hind limbs cannot bend forward, which is very important for movement in the water. Also, its body surface is smooth, almost It has become streamlined and is very suitable for fast swimming and diving in the water. Its keen vision and hearing coupled with its dexterity in the water make it easier to catch various fish. But once on land, its movements appear very clumsy. It's ridiculous. The limbs that are good at swimming can only serve as a support, so they have to crawl slowly. Their clumsiness on land has also become one of the reasons for their future extinction. During the lactation period, monk seals are very vigilant. Once danger is discovered, , will immediately push the baby seal into the water, and then dive and escape. If a baby seal is captured, the big seal will snatch the baby seal regardless of its own safety. If a person snatches the baby seal, the big seal will be furious and shout to the sky. Humans launched an attack. However, in the end, they could not escape the hands of humans. A few paragraphs: The seal is an ancient and rare seal. It is the only seal in the world that lives in tropical waters all its life. Historically Monk seals once bred in large numbers in the Caribbean and the Mediterranean. Due to indiscriminate hunting by humans, monk seals are now hard to find in other parts of the world, and only a small group survives in the northern part of the Hawaiian Islands. Different from seals that like to live in cold water, monk seals like tropical warm water. In the middle of the rippling Pacific Ocean, there is a jade-like island called Nihau Island, which is a pasture island. Monk seals mainly live here The island thrives on the beach. This island is private. In order to protect the environment of the island, the owner of the island generally does not allow scientific researchers to visit the island for inspection, so no one knows how many monk seals there are on the island. 5. Orino Crocodile: There are four species of crocodiles in the world that are threatened by overhunting and environmental pollution. One of them is the Orinoco crocodile living in Venezuela. It is the largest crocodile in the Americas and a treasure among Venezuelan animals. For many years, Venezuela Relevant units have taken various measures to protect the endangered Orinoco crocodile, and have achieved results. In 1990, the Ministry of Environment and private organizations launched an initiative to formulate a plan to protect the Orinoco crocodile. Through artificial protection and breeding, the number of Orinoco crocodiles increased. The number of this precious animal is because it is no longer possible to reproduce in large numbers in the natural environment. This kind of crocodile only exists in Venezuela and Colombia. It was originally estimated that there were only 250 crocodiles. After 10 years of conservation work, 2,150 crocodiles have been bred and released into the wild. Rinoco crocodiles, 1,400 of them in Apure state. It is estimated that there are now 3,000 crocodiles over one year old, maybe 5,000. In order to protect crocodiles, relevant departments have established three crocodiles in Cojedes and Portuguesa states. A crocodile farm allows adult crocodiles to breed there and then artificially feed them for a year. After the crocodiles grow to 80 centimeters, they are released into the river at the beginning of the rainy season. For follow-up observation, technicians tie a ring on the crocodile's leg and place it on the scales. Mark on it.

Activities to protect crocodiles have received strong support from relevant departments and private enterprises. Feeding an adult crocodile costs 150,000 bolivars per month. It eats high-cost food such as horse meat and fish. The farms also add vitamins to the food. Enhance the crocodile's physique. 90% of the farm's budget is used to purchase crocodile food. The Ministry of Environment is seeking international assistance to increase funds to better protect Orinoco crocodiles. 752 kilometers away from the Venezuelan capital Caracas A biologist holds several day-old Orinoco crocodiles in the Apure State Biological Reserve. As part of the program to protect Orinoco crocodiles, more than 130 crocodiles aged one to two years old were born in cages Released back into nature. 6. Mouse lemur: The smallest monkey in the world. The island of Madagascar in the Indian Ocean in southeastern Africa is known as the "Lemur Island". There are more than 20 kinds of lemurs on the island, mainly There are big lemurs, small lemurs, mouse lemurs, gray lemurs, silky lemurs, velvet lemurs and ring-tailed monkeys. The Latin name of lemur means "ghost". They move elusively in the tropical forest. It likes to be noisy. There are great differences in appearance, size and habits between different species. The giant lemur is the "giant" among existing lemurs. It is about 1.2 meters long and has a strong body. The top of its head and back and waist are white, and the rest are white. All are black, with alternating black and white. The little lemur is only 20 centimeters, chubby, has two big eyes, and its tail is slightly shorter than its body. In the hot and dry season, it has the habit of aestivation. At this time, it relies on the fat stored in its tail to survive. To maintain life. The mouse lemur has a body similar to that of a mouse and looks like a mouse. It has a long and protruding snout and a moist nose, which is like a dog's nose. The gray lemur is similar in shape and length to the mongoose, with a round face and the front of the mouth. They are pointed and protruding, with particularly large front teeth on their lower jaw. They live in the forests of eastern Madagascar. Only in the early morning and dusk can you see males and females moving in pairs on the trees. It is difficult to see them living together. Lemurs are larger than cats, covered with pure white silky soft fur, and have a long, beautiful and flexible tail. The original lemur has a fluffy tail, like a white scarf around its head, and is agile. In addition, the Torico coast of the Caribbean Sea The nearby Cayo Santigao Island and Gushan Island in Fuxian Lake, Yunnan, China, as well as Nanwan Macaque Island in Lingshui County, Hainan, are all famous macaque islands, especially Nanwan Macaque Island in Lingshui County, Hainan Province, which is close to the South China Sea. The island is famous. Macaques are also called "little hozens" and "rhesus monkeys". Their fur is grey-brown, and their chests are orange-yellow and shiny. Their chests, abdomen and legs are dark gray, their faces and ears are exposed, and their buttocks are red. Hao. Take a yacht from Xincun Port in Lingshui County, Hainan Province, and it only takes more than 10 minutes to reach Macaque Island in Nanwan Peninsula. Macaque Island was originally called Nanwan Monkey Island. Nanwan Peninsula faces the sea on three sides, with only one side facing the sea. The land is connected, with 12 rolling hills of varying sizes, facing each other across the sea, like an isolated island. Because many groups of macaques live here, people call it "Macaque Island". This is a veritable macaque paradise. The area is 9 square kilometers, and the mountain is 15 kilometers long. There is a small peak in the middle. The mountain is divided into east and west sections by river beaches 50 meters wide on both sides. You can see layers of mountains and ravines. When you come to the tourist area, you will see a vivid picture A lively picture unfolds in front of you. There are macaques all over the mountains and plains, some on the top of the mountain, some in the ravine, some occupying a hilltop alone, and there are also two or three groups living on the same hilltop. Each group of monkeys has a "big king" and "second kings" ". There is a monkey viewing pavilion on the mountain, where visitors can watch the wonderful performances of macaques and experience a wild atmosphere that is obviously different from those in ordinary parks. Some macaques are drinking water by the well, which reminds people of "monkeys fishing for the moon" ; Some are flying and jumping between two trees or somersaulting on the ground, making people feel as if they are watching the wonderful performance of "Sun Dasheng" in "Huaguo Mountain"... 7. L. Kemp's Ridley Turtle (L. Kemp's Ridley Turtle) Currently Among the 12 most endangered animals in the world, it is the only one with an increasing number. It needs to go through a growth period of 11-35 years. 8. Orinoco Crocodile (scientific name: Crocodylus intermedius) There are only 250-700 in the wild. Survival. Mainly in Cuba and Venezuela. 9. Thailand Hog-nosed Bat (Kittis Hog-nosed Bat) The Hog-nosed Bat lives in the limestone caves on the Guayenoi River in Kanchanaburi Province, Thailand. The length of the head and body is 2.9 cm, and the length of the wings is The width is 13 cm and the weight is 1.7 grams. 10. Hawaiian snail (genus Achatinella) 11. Spix parrot: In the wild state, Spix parrot

Although parrots are not completely extinct, they are extremely rare. In 1990, ornithologists looking for this bird only found one surviving male bird, living in the remote northeastern region of Brazil. Currently, about 31 have been captured. Birds are the only hope for this bird to survive. The macaw is a large long-tailed parrot that lives in tropical America. It has colorful feathers, but this beloved parrot may have become extinct, at least in the wild. Exists. According to biologists, there is a blue wild macaw, which is the last one of this kind, but it has not been seen for a long time. It may have suffered an accident. Biologists have been closely observing this species. There is only a 19-year-old parrot, but they have not seen it in the past two months. It may have become a meal for eagles or been captured by poachers. 12. Micro pig (pigmyhog, scientific name is Sussalvanius) ): The smallest pig in the world, a type of wild boar, mainly lives in northeastern India. It is 60 cm long, about 25 cm high, and the adult pig is less than 10 kg. It once existed in large numbers in the Himalayas, but now it is only found in the Asan region of India. There are only a few of them in Naas National Park. Their genes are not much different from those of domestic pigs.
