Chapter 186 (1/2)

After dinner the next morning, Fang Ye held a meeting with the civilian staff to discuss the design of other exhibition boxes. He was really a little busy with so many exhibition boxes. There were too many materials to find.

Civilian personnel have collected a lot of information for some time, which is useful at this time, including the original habitat, suitable temperature and food of various animals, and put forward their own ideas and opinions.

In addition to the general exhibition box, there are some exhibition areas with larger space in the amphibious and crawling hall, with an area of 20-50 square meters!

At present, two are prepared, one for Zhuyeqing and the other for Chinese giant salamander.

Both belong to amphibians and reptiles with great reputation and characteristics in China. Of course, there should be some arrangement in their exhibition area. Although the size of bamboo leaf green is small, it is not a waste to use a large exhibition area.

Chinese giant salamander is commonly known as giant salamander. Although it is called fish, it is not a fish, but the largest amphibian in existence. The largest body length can reach two meters. It is one of China's national treasures.

The earliest fossil found is 165 million years ago. It can be said to be a living fossil of the animal kingdom! The giant panda, also known as a living fossil, has a history of only 8 million years.

Compared with ordinary frogs and toads, giant salamanders are much more picky about their living environment. In nature, all habitats where giant salamanders haunt are dense mountain forests with vegetation coverage of 80% - 90%. There must be plenty of water around. There must be mountain streams and streams. Giant salamanders need wet skin to help them breathe. The dense jungle can not only block the sun, but also create an air environment with high humidity, Avoid suffocation due to dry skin.

Even if the adult giant salamander has the ability to climb the land, it only dares to move on the land next to the stream. Therefore, the mountain stream and running water are the necessary conditions for the survival of the amphibian giant salamander!

In addition, the water temperature of 16-28 degrees is the most comfortable for the giant salamander. When the water temperature is lower than 4 degrees or higher than 33 degrees, the food intake of the giant salamander will decrease, the action tends to be slow and the growth will be slow.

The giant salamander is also very particular about the geology and landform of its habitat. It likes to inhabit in limestone areas. Under the long-term erosion of the river, many natural karst caves, underground rivers and caves with backwater will be produced in these areas. Adult giant salamanders generally live alone, but once they identify a cave, they will not move easily.

These caves have not only become the best refuge for giant salamanders, where they take refuge from light and natural enemies, but also the back garden for their hatching offspring. It is precisely because of this specific hidden breeding place that giant salamanders have been handed down from generation to generation for hundreds of millions of years.

Moreover, the giant salamander also has high requirements for water quality. It is not too much to say that it has a habit of cleanliness. The water suitable for life must be clear and clean, rich in minerals, and the water-soluble oxygen content cannot be less than 5 mg / L. in the stage of larval development and growth, the water oxygen content is even higher than 5.5 mg / L, which is close to the standard of human healthy drinking water.

Dense forest, moist air, suitable temperature, hidden caves, flowing river water, clean water quality and rich food are basically indispensable for giant salamander.

It is precisely because of the harsh requirements for the living environment that the giant salamander is also regarded as an environmental indicator, known as the ”canary in coal”. If you can see the giant salamander in the wild, it shows that the environment here is quite good and can basically be called a paradise.

However, with the increase of human activities and environmental pollution, the number of wild populations has decreased sharply and is in extreme danger. It is listed as a national second-class protected wild animal.
