About tigers.

Reading an article may be helpful to you.

Tiger has eight subspecies, each of which has a life span of about 25 years and a size of about 1.4 to 3.5 meters. Three of them have become extinct, mainly because human hunting and invasion have narrowed their living range and their territory is not enough to survive.

● Siberian tiger (scientific name: Panthera tigris altaica), also known as Siberian tiger, Amur tiger (Russian name of Heilongjiang is amur river), Ussuri tiger, Siberian tiger and Korean tiger, lives in Siberia and the Far East of Russia. It is the largest tiger with the most precious fur, and it is well-deserved to be called the "Tiger King". It is 2.6 meters long, 65438. You can easily kill a strong cow with light yellow hair, and you are not afraid of the cold. According to statistics, there are only 150 ~ 400 wild tigers. China government has stipulated strict protection measures to compensate farmers whose cattle and sheep are preyed by tigers, and banned the production and sale of traditional Chinese medicines with tigers as raw materials, such as tiger bone paste and tiger bone wine, blocking the application market, but wild Siberian tigers are still very rare.

● The South China Tiger (scientific name: Panthera tigris amoyensis) lives in China and is a unique species in China. From Shandong Peninsula to Lingnan, due to the dense population in China, South China tigers have more contact with people. The stories of tiger-human struggle described in the history of China are all about the South China tiger, which is very small, only a little bigger than the Indochina tiger, so Song Wu, a Shandong native, can kill one with his bare hands in Water Margin. The last wild South China tiger was shot at 1994, and there is no conclusive evidence to prove the existence of wild population. However, since the 1990s, there have been traces of South China tigers in Jiangxi, Hunan, Fujian, Guizhou and other places. Experts predict that the number of wild populations is only 30-50. There are about 70 South China tigers in zoos all over China, all of which were bred by 6 South China tigers captured in 1950s. The change of their gene combination is not enough to maintain this subspecies, so I hope this subspecies will not become extinct.

● Balihu (scientific name: Panthera tigris balica) only lives in Bali, Indonesia. It is the tiger with the most and densest stripes, with more than 100 stripes. It is reported that the last Balihu tiger was hunted in 1937 and is now extinct.

● The Southeast Asian tiger, also known as the Indo-Chinese tiger (scientific name: Panthera tigris corbetti) is the smallest tiger, about 1.6 meters long, mainly distributed in southern China, Cambodia, Laos, Vietnam and Malaysian Peninsula. It is estimated that there are 1227- 1785 wild tigers, and about 60 live in Asia.

● The Java tiger (scientific name: Panthera tigris sondaica) only lives in Java Island, Indonesia. The last witness reported it at 1979, which is believed to be extinct.

● Sumatra tiger (scientific name: Panthera tigris sumatrae) only lives in Sumatra Island, Indonesia. Its color is dark, close to red, and its hair is short, so its muscle outline is obvious and spectacular. At present, there are more than 400 Sumatran tigers living in five national parks, but 1998, 66 tigers were killed by poachers.

● Bengal tiger (scientific name: Panthera tigris tigris) is one of the most surviving tigers at present, living in Indian forests, and there may be 3,000 to 4,600 tigers. The average weight of adult male Bengal tiger is 220kg, which is close to that of male Siberian tiger, and that of female is 130kg, which is slightly lower than that of Northeast tiger. At that time, it was the favorite hunting object of British colonists. Lord Mumbart killed 180 tigers in his life. At present, the Indian government also gives protection. It is said that Bengal tigers have black breeds in dark tropical forests, but they are rare. Is there any evidence?

★ Bengal tiger and white tiger species. ★

Li Haihu, named Xinjiang Tiger (scientific name: Panthera tigris virgata), is distributed in China and lives in Xinjiang, Iran, Afghanistan, the former Soviet Union, Central Asia and Iraq, so it needs more hunting territory. It is reported that the last Li Haihu was found in 1968, and has not appeared since then, and has become extinct. Tricolor tiger

Other tigers

Black, blue and tiger, just a legend, no one has seen it. A cat expert traveled all over the world and only found the white tiger in India, but Hei Hu was nowhere to be found, so he thought it only existed in legends. Who would have thought that the miracle happened in China, the specific area is Miyun County, but there is no evidence. It's probably a variation of the common tiger.

In artificial breeding, albino varieties are rare. Those with brown stripes on a white background are called "white tigers", and even the stripes are lighter, so it is almost difficult to distinguish them as "snow tigers".

Southeast Asian tiger

Indo-Chinese tigers are smaller and darker than Bengal tigers, and their stripes are short and narrow. The average length of male Indo-Chinese tiger is 2.7m from beginning to end, and its weight is about 180 kg. The female Indo-Chinese tiger is small, estimated to be about 2.4 meters long and weighs nearly 1 15 kg. Indo-Chinese tigers feed on wild boar, deer and bison. The size of this tiger's territory is unknown, but in an ideal habitat, there are usually 4 to 5 adult tigers per 100 square kilometer. There is a small distribution in China, which is a national first-class protected animal.
