What are the endangered animals in the Yangtze River Basin?

The endangered animals in the Yangtze River basin mainly include Chinese sturgeon, Chinese alligator, finless porpoise, elk and baiji dolphin.

The finless porpoise of the Yangtze River is an endangered animal. According to relevant statistics. Up to now. There are only more than 800 finless porpoises left. China is the homeland of the Yangtze finless porpoise. Protecting the finless porpoise is also the responsibility of each and every one of us.

Yangtze white sturgeon. The Yangtze River white sturgeon is the oldest in the Yangtze River, the oldest fish in life, the well-documented survival time is about 250 million years, they witnessed the end of the dinosaur era, after years of hardships and finally survived to the modern age, the Yangtze River white sturgeon is very large, since ancient times there are "thousands of catties of wax, ten thousand catties of elephants." The "elephant" refers to the Yangtze River white sturgeon, that is to say, it can grow to tens of thousands of catties, although the largest white sturgeon caught since the records are more than 1,000 catties, but in ancient times, the Yangtze River white sturgeon is likely to grow to such a huge size.

The adult white sturgeon can be up to seven or eight meters long, swim fast, is a carnivorous fish, because it is at the top of the food chain in the Yangtze River, it is also known as the "water tiger", "the king of Chinese freshwater fish", etc., it is also one of the ten largest freshwater fish in the world.

However, due to the development of shipping, water pollution, water conservancy facilities, human fishing and other factors, the number of Yangtze white sturgeon has decreased sharply in the past 100 years, and in 2009, the IUCN assessed the endangerment level of the Yangtze white sturgeon species as "critically endangered", and in 2020, some scholars officially declared the Yangtze white sturgeon extinct, and its real extinction time was several years earlier.

Baiji. Baiji dolphin has the name of the giant panda in the water, it can be seen that people attach importance to them and love, the history of Baiji dolphin survival is about 25 million years, it is a large fish in the Yangtze River, and it is also the only kind of cetacean that only lives in freshwater, living in the waters of 1700 kilometers from Nanchang to the mouth of the Yangtze River in Shanghai, and later due to the influence of the environment, the living environment of Baiji dolphin is mainly concentrated in Dongting Lake and other waters.

The baiji dolphin is a first-class protected animal in China, but unfortunately, in 2004, after the death of the last baiji dolphin in captivity, the baiji dolphin was never found, in 2006, after a joint investigation by scientists from six countries, the baiji dolphin was declared functionally extinct in 2007, until now, there is no trace of the baiji dolphin.

The white-sided dolphin was declared extinct in 2007.

The white-sided dolphin, also known as the baiji dolphin, is a rare aquatic mammal unique to China, known as the "water panda", and is a precious "living fossil" for the study of cetacean evolution. The last time it was seen was in 2002, and in 2006 it returned after an unsuccessful survey of its habitat, and in 2007 it was labeled extinct.

The baiji dolphin is the first animal to be recognized as extinct since the founding of the People's Republic of China. Complete.

Yangtze River BasinClass 1 protected animalsThere are finless porpoises, bream, and moreamWhite-sided dolphinsWait.

Tuantou bream, commonly known as Wuchang fish, and Changchun bream and triangular bream are collectively known as the three sisters of bream. It is famous for being produced in Liangzi Lake in Echeng, Hubei Province. It is native to the Yangtze River basin in Chinese mainland, and is the most abundant in the middle reaches.

White-sided dolphin: The white-sided dolphin is a freshwater cetacean endemic to China, also known as white, white-flag, white-fin, etc., and is only produced in the middle and lower reaches of the Yangtze River.

Is it the entire Yangtze River Basin, or the middle and lower reaches of the Yangtze River or the Jiangnan region?

Shanghai's newly built Chenshan Botanical Garden has an area with a variety of rare plants.

Putuo hornbeam: Putuo, Zhejiang, it is said that there is only one in the world. . .

Tianmu Ironwood: West Tianmu Mountain, Zhejiang, it is said that there are 5 trees.

As for some endangered protected animals and plants, the state has a special catalog. Of course, there are many originally protected plants, which are now also popular, such as metasequoia and ginkgo biloba, which were also endangered and protected species at the beginning

Endangered species in the Yangtze River Basin are valuable resources of the country, and they play an important role that cannot be replaced by other species in maintaining ecological balance and biodiversity. At present, the international community has a strong call for the protection and rescue of endangered species. China is a member of the International Convention on Endangered Species in the Yangtze River Basin or international organizations, and has done a good job in the protection of endangered species in the Yangtze River BasinIt is of great significance to maintaining ecological balance, promoting the building of socialist spiritual and material civilization, safeguarding China's international reputation and image, and better promoting opening up to the outside world.

To a large extent, we do not protect endangered species because we do not have the right publicity, and some localities are willing to spend money to publicize China's policies on the protection of endangered species and their positive significance through television, newspapers, and radio, while others have no regard for propaganda work.

It is necessary to stipulate through laws and regulations that all localities have the responsibility and obligation to publicize the great significance of the protection of endangered species, and each country should allocate a part of the media resources to publicize the protection of endangered species.

We should not only do propaganda in the city and on television, but also go to the fields and do propaganda by word and deed. It is necessary to widely publicize the great significance of protecting endangered species, publicize China's consistent position and attitude towards the protection of endangered species, as well as the significance and role of relevant national laws and regulations in protecting rare animals.

Conservation of rare animals can better maintain biological diversity

Rare animals are a precious treasure shared by all mankind. The richer the species in an ecosystem, the more creative it becomes. All living things in nature are interdependent and mutually conditioning.

The extinction of each species is a sign that many species are about to die. Only by protecting the biological chain can we better maintain the ecological balance and policy provisions. Each species is an important member of the ecosystem, and through the relationship of the food chain, species play an interdependent and mutually restrictive role.

Ensure the normal development of scientific research and educational activities

Endangered animals are experimental materials for scientific research and play an important role in zoology, evolution, ecology, genetics, modern medicine, bionics and other disciplines. Scientific research institutes, colleges and universities, zoos and museums collect, display or exhibit specimens of endangered animals, which play an important role in scientific research and teaching, publicity and education, and law enforcement activities.

Endangered animals are precious, irreplaceable and renewable natural resources, which play an important role in maintaining ecological balance, promoting economic development, meeting the growing material and cultural needs of the people, developing foreign relations, and improving socialist spiritual civilization.

It protects the diversity of species, maintains the stability of the natural ecology, and maintains the ecological balance. Endangered animals are a precious, irreplaceable, renewable natural resource, and protecting them also protects humanity itself.

In this way, the abundance of these species can be conserved, and biodiversity can also be conserved, which will also contribute to the ecological balance in the future.

Avoid them from killing, the living environment can be more comfortable, and there is no need to worry about the pursuit of natural enemies. Provide them with a good breeding environment.

It can play an effective role in protection, reduce the harm of people with bad intentions to endangered species, and also force people to create a good living environment for these endangered animals.
