10 rare animals in the world

10 rare animals in the world are: Central South antelope, finless porpoise, Hu Jin, flat shark, elephant shrew, Far East leopard, and? Northeast deer, red wolf, Javanese rhinoceros, pangolin.

1, Central South antelope

Central South Antelope, also known as Wu Guangniu, Annan Spindle Antelope, Jianjiao Cattle, Sola Antelope, etc. It is a single species in the genus Central South Antelope of Artiodactyla. 1992 was discovered, and it was called the Asian unicorn. Although called "antelope", this species has been identified as belonging to Bovine Subfamily.

The number of ethnic groups is doubtful. At present, only 1 1 is recorded in the world, so it is listed as a critically endangered species in the red list of IUCN.

2. Little Dolphin

Small-headed porpoises, also known as harbor porpoises, Pacific porpoises, Gulf porpoises, Gulf porpoises or Gulf porpoises, and California Gulf porpoises, are rare porpoises. They are endemic to the Gulf of Northern California. The capybara is the most endangered cetacean in the world and has been listed as an extremely endangered species since 1996.

1997 The estimated number of finless porpoises was about 600, and then it decreased year by year. 20 14 years, this figure is less than 100, 20 15 years, about 60,20165438+10 months, which is 30.

According to the acoustic data collected in the summer of 20 18, there are at most 22 dolphins and at least 6 young dolphins left in the world, and IUCN estimates that there are about 10.

3. Hu Jin

Hu Jin, sometimes called Hu Jin spotted tiger or strawberry tiger, is a kind of tiger whose color changes are caused by recessive genes. Like White Tiger and Hei Hu, it is a color type, not a separate subspecies. ?

Hu Jin's color is famous for its gold or light gold and reddish brown (not black) stripes. It comes from a hidden feature called "broadband", which will affect the generation of black in the hair growth cycle. Tiger color, which is different from typical orange-black stripes, does exist in nature, but the proportion is very small.

In 20 14, an adult female Hu Jin was photographed with a camera trap in Gazilanga National Park, which provided visual confirmation of the color distortion of the wild tiger population. This woman of childbearing age has been a photographer of Mayuresh Hendre, and has been monitoring until 20 19.

This rare tiger can only be found in cages. Unlike other tigers, it has a recessive gene, sometimes called strawberry tiger or Hu Jin spot. Most of the genes of these tigers are similar to those of Bengal tigers, but they usually have the genes of Northeast tigers in their pedigrees.

Hu Jin's wilderness last appeared in India in the early period of 1900, and they are usually related to areas with high clay content in soil. We can confirm that there are less than 30 tigers in captivity.

4. Flat shark

Flat shark is a kind of shark under the family Flat Shark, which was once widely distributed in the coastal waters of the East and North Atlantic. Their bodies are flat, their pectoral fins and anal fins are wide, and they can be disguised as a part of the seabed. They are characterized by conical tentacles, no spines on their backs, gray or brown, and some dark and light markings. They can be as long as 2.4 meters.

Flat sharks, Nocturnal Animals, will hide in sediments and ambush their prey. They mainly eat bony fish, rays and invertebrates in benthic areas. They have no placenta, and female sharks give birth to 7 to 25 young sharks every other year. They are not very aggressive, but if they are harassed, they will quickly bite each other.

Flat sharks were caught and hunted as food as early as ancient Greece and sold to Europe as Ankang fish. Since the mid-20th century, frequent fishing has greatly reduced their numbers, and now they have become extinct from the north. The rest of the community is also threatened by low reproduction rate. Therefore, IUCN listed them as extremely dangerous species.

5. Elephant shrew

This small African rodent is the golden-waisted elephant shrew, which is the largest genus in the elephant shrew family, and its close relative is the gray shrew.

The shrew, known as the golden-waisted shrew, is one of the most endangered species in the world, mainly because of the scattered forest and anthropological environment.

Their numbers are the most prominent in Alhabo Kosokok Nature Reserve, but due to deforestation, we have destroyed their ecosystems.

Hunters use traps to catch them, but locals don't use them as food sources because their meat tastes bad.

6. Far East Leopard

The Far East Leopard, or Northeast Leopard, is a big cat carnivore and one of the nine subspecies of leopard. Named after living in the Far East, it is commonly known as the Earth Leopard in China, and it is a national first-class protected animal.

It has been widely distributed in the forests of China's northeastern Primorsky Territory, Jilin, the northern part of the Korean Peninsula and the Russian Far East. It is the only leopard subspecies that adapts to the living environment in snowy areas and overlaps with the habitat of Siberian tigers. ?

Because human activities have intensified the disappearance of forests and rampant hunting activities, there are currently less than 50 wild Far Eastern leopards in the world, most of which live in the Russian Far East and the demilitarized zone between North Korea and Russia. At present, the international community has strengthened the protection of the Far East Leopard, but the situation is still not optimistic.

7、? Hogapi

The roe deer (pinyin huòjiāpí) is a large mammal, which was not found in Zaire forest in Africa until 190 1, also known as Okapi deer. It is an cloven-hoofed animal of the Giraffe family. Related to giraffes, it is the only close relative of giraffes that is not extinct.

Because it has black and white stripes on its back, it looks like a zebra. Someone once thought? The roe is produced by the mating of giraffe and zebra, but in fact it is not a close relative of zebra. Biologists believe that the ancestors of giraffes looked like before their necks became longer. The difference is not far. ? Tapirs are distributed in the rainforests of Central Africa, Democratic Republic of Congo and northeast China.

Although this rare species is sometimes called a forest giraffe, it doesn't look like a giraffe at all unless you look closely.

The history of roe seems to be traced back to ancient Egypt, where we can find murals of these animals.

Before the 20th century, there were stories of "African unicorns" in Europe and Asia. 1887, Henry Morton Stanley described a donkey named "Artie" in Congo.

8. Red Wolf

Red wolf (scientific name: Canis lupus rufus) is a subspecies of gray wolf living in North America and distributed in the southeastern United States. It was once considered an independent species. A recent study pointed out that its ancestor was a hybrid of gray wolf and coyote.

Since 1970' s, it has faced extinction due to fur and conflicts with farmers. In addition, hybridization with hyenas is also an important reason. Domesticated wolves once thought to be extinct in the wild were introduced to North Carolina in 1989. The number of wild population increased to 100- 120 in 20 12 years, and decreased to 50-65 in 20 18 years. In addition, there are 150 red wolves in captivity in the United States.

Because of the scarcity of red wolves, they often can't find similar breeding, but mate with coyotes in the prairie of North America, which makes the number of pure red wolves decline.

Body length 1. 1 ~ 1.3m, with an average weight of 25kg. The upper-class gray wolves with high social structure hunt deer in groups and rabbits and rodents when they are alone.

9.java rhinoceros

Javanese rhinoceros, also known as small one-horned rhinoceros, belongs to Chiroptera rhinoceros family and is closely related to Indian rhinoceros. At present, it is almost extinct, leaving only about 50 to 60 heads. Because of overfishing, there is only one population left in Java, Indonesia, among which Indian subspecies and Vietnamese subspecies have become extinct.

Java rhinoceros 1989 was shot with an infrared camera in Jixian National Park, Vietnam. At that time, it was thought that there were at least about 13 populations (a subspecies of Javanese rhinoceros in Vietnam). But because of the weak protection measures in Vietnam.

And the escalating hunting methods of poachers, the Javanese rhinoceros in Vietnam was finally extinct in April 20 10 due to rampant poaching. At present, there are only 50 survivors left in Ujonkulong National Park in Java, Indonesia.

Unlike other rhinos, Javanese rhinos don't collide with people or animals that are too close. At the slightest sign of trouble, the Javanese rhino will run away.

It is believed that the last female Javanese rhinoceros in Vietnam was killed by poachers in Jixian National Park on April 20 10, and its rhinoceros horn was cut off. Since then, IUCN personnel and local researchers in Vietnam have never found the figure, footprint or feces of live rhinos in Vietnam.

Therefore, the World Wide Fund for Nature (WWF) and the International Rhino Foundation (IRF) announced after a nationwide survey in Vietnam that the last Javanese rhinoceros was killed in April 20 10, and the Javanese rhinoceros became extinct in Vietnam, which also marked the extinction of the Vietnamese subspecies Javanese rhinoceros.

10, pangolin

Pangolin, formerly known as shad, shad and shad in China, is the general name of a class of mammals of Pangolinidae, belonging to the only family of Pholidoceae, with 3 genera and 8 species, distributed in tropical and subtropical regions of Asia and Africa. They are covered with scales of horny nails from beginning to end, burrow at night and feed on termites.

The earliest record of pangolin can be found in Tian Wen of Chu Ci: "Where is the loach?" Wang Yi, a scholar in the Eastern Han Dynasty, noted: "A group of loaches and shads, with four legs, went out of the south."

Gaoyou, a native of the Northern Wei Dynasty, is famous for recognizing pangolins. Tao Hongjing, a medical scientist in the Southern Dynasties, believed that pangolins "can land and water, leave the shore at noon, open scales like death, lure ants into the armor, that is, close the water, and all the ants that open the armor come out and surround them with food." Li Shizhen, a medical scientist in the Ming Dynasty, accurately pointed out that pangolins don't use scales to lure ants, but "often spit out their tongues to lure ants to eat".

On July 20 14, the pangolin special group of IUCN Red List Species Survival Committee, chaired by the Zoological Society of London, pointed out that pangolin is the most commonly smuggled mammal in the world.

All pangolins are facing great threats to their survival, among which China pangolin and Malay pangolin are rated as "extremely endangered" species by IUCN, and illegal smuggling activities are extremely rampant. With the sharp decline in the number of the four largest pangolins in Asia, smugglers turned to Africa to meet the huge market demand.
