The biological population on the earth is very large, and China's endemic species are also increasing, wave after wave of protected organisms appear in everyone's field of vision, which also shows that China has indeed become much better after maintaining the ecological environment, so it can see more scarce animals and plants appear. The first two days you should also see, China Zhejiang found a large number of "Chinese leeks", which is a very scarce plant, known as the plant world "giant panda", the number of about 20,000 plants, covering an area of more than 300 square meters, so very rare.
After this, another kind of national key first-level protected wild animals appeared in China, and it is also a species endemic to China, which has aroused heated discussion among many people. It is really more and more scarce animals and plants that appear, so that everyone knows the benefits of environmental changes in our country.
<h1 class= "pgc-h-arrow-right" > unique to Guilin - cat mountain salamander</h1>
According to scientific reports, the cat mountain salamander is also known as a "living fossil", because the salamander originated more than 300 million years ago, and the dinosaurs lived at the same time, Su Yo Yi is very long, the creature in 2003, was collected by scientific researchers - that is, what everyone calls "four-legged monster fish", and then through analysis, the creature is not an ordinary population, but a new organism, so in 2006, China named it a new organism, named "Cat Mountain Salamander", and in the "Cat Mountain Salamander", and in the "Cat Mountain Salamander", and in the "Cat Mountain Salamander" Journal of Animal Taxonomy.
This organism is the only organism in China today, and only found in the area of Maoershan Mountain, mainly living in the alpine swamp wetland area above 1900 meters above sea level, and from the existing situation, this biological distribution is very limited, only Guilin has, so it belongs to the endemic biological population of Guilin, it can be said that only Guangxi exists, the number is about 1500 (2008), in 2013 survey, the number of cat mountain salamander population is about 1582, indicating that there is still an increase, very good. Cat mountain salamander prefers to eat more small invertebrate aquatic organisms, such as earthworms and Shi'e larvae, in general, male salamanders can grow to 152.3 ~ 160.2 mm, female salamanders 136.1 ~ 155.2 mm, this is its basic situation.
<h1 class= "pgc-h-arrow-right" > cat salamander is often mistaken</h1>
From the appearance of the cat mountain salamander, it is very easy to recognize mistakes if you are not careful, it is very close to the appearance of the Chinese salamander (Hynobius chinensis Gonther), and the best recognition area is - no palm protrusion, no claplosis. At the same time, the creature is also very similar to the salamander source, it is really completely cloned, many people say that there are a lot of this creature in the big ravine of their hometown, but it is not, and most of the creatures seen by humans are a creature called "fat salamander", so it is a little different.
The fat salamander is also a second-class protected animal in China, which can also be seen in most mountainous areas of Guangxi, and the number is much more than that of the cat mountain salamander, and the average person cannot distinguish it. At the same time, the "cat mountain salamander" likes to live in a dark and clean waterhole, which is generally not easy to be found, so everyone will see such a similar creature in the future, as long as they do not bother it, after all, it is difficult to identify with the naked eye, and there are too many species displayed.
After expert research, although the biological group is expected to have about 1500 species, it has been listed as the world's "critically endangered" amphibian, and the IUCN has not given a rating for the time being, lacking data. Therefore, in the end, how many creatures there are in Guilin Mao'er Mountain, there is no answer for the time being. But again, now that these creatures are classified as protected creatures, it is important not to destroy their habitats.
<h1 class="pgc-h-arrow-right" > the reason why there are not many cat salamanders? </h1>
Obviously, on the earth, the scarcity of wild animals and plants increases, the relationship with humans is the largest, the main threat of the cat mountain salamander is still related to humans, humans in the breeding area of the cat mountain salamander for large-scale tourism development, building houses, building roads, etc., has a direct impact on their lives, so if the cat mountain salamander can restore it to its original appearance, it is really too difficult. Today, if we want to expand the population of the cat mountain salamander, it is only possible to restore the ecosystem.
At the same time, artificial reproduction is used to increase this biological population, mainly because of the increase of suitable habitat area for it. Therefore, the small number of cat mountain salamanders can also be regarded as the greatest impact of humans. Strictly speaking, now that it has become a nationally protected species group, its status is higher, and we should know more about the importance of this biological protection.
According to the data of the National List of Wild Animals under Key Protection, there are now 980 species and 8 categories of wild animals in the list, of which 234 species and 1 categories of wild animals are protected at the national level and 746 species and 7 categories of wild animals under national second-level protection. So this also shows that the species group we protect is very large, the cat mountain salamander belongs to the unique population of Guilin and China, and we also look forward to expanding the population as soon as possible, which has a decisive role in enriching the biodiversity of our country, and at the same time has great significance for the further promotion of China's ecosystem.
