The front of the body is flat, and the tail gradually turns to the side. There are obvious skin folds on both sides of the body, the limbs are short and flat, the forelimbs are toes, the hind limbs are toes, and they are slightly webbed. The tail is round and has fins up and down. The body surface is smooth and covered with mucus. The back of the body is mixed with brown and red, and the ventral color is lighter.
Living in Qingxi in mountainous areas, they usually hide in the crevices of the mountain stream, and the caves are below the water surface. The cry is also like a baby crying, so it is commonly known as "giant salamander". Laying eggs in July-August every year, with more than 300 eggs per tail. Male salamanders wrap their eggs on their backs and hatch after 2-3 weeks.
China is endemic to North China, Central China, South China and Southwest China. The heart has a special structure and some reptilian characteristics, which has important research value. The number is scarce and needs protection.
Protection: Because of its tender meat and delicious taste, it has been hunted for a long time. The number of producing areas has dropped sharply, and some producing areas are on the verge of extinction. It has been listed as a national second-class protected animal and CITES Appendix I. ..

Why is the giant salamander called the giant salamander?
This is a giant salamander.
Why is a python called a python?
Giant salamander is not a fish, because it can live in the water like a fish and cry like a baby, so it is called "giant salamander"
In fact, its scientific name is Chinese giant salamander, which belongs to amphibians. Giant salamanders like to live in mountain streams at an altitude of 200- 1600 meters. They usually hide in caves with swirling water during the day and go out for food at night or at night. It has a wide range of eating habits and likes to eat fish, shrimp, crabs, snakes, birds and frogs. However, its teeth only have predation ability, but have no chewing function, so when it catches prey, it can only swallow it with its mouth open and then slowly digest it in its stomach. Sometimes it swallows a baby, and it can't be fully digested for more than ten days, so it has strong hunger tolerance.

Why is the giant salamander an amphibian?
The giant salamander is not a fish, but the largest amphibian in the world, which is produced in China. Because it can live in water like a fish and its cry is like a baby's cry, it is called a giant salamander. In fact, its scientific name is Chinese giant salamander, which is more important than net animals. The giant salamander has a wide and flat head, big eyes and a small mouth, and a long and flat tail. Its body can reach 1.8 meters and dozens of kilograms. Its body surface is smooth, with mucous glands and scattered warts, and its back is S-brown with black spots. Its limbs are very short. Its forelimbs have four fingers and its hind limbs have five toes. When swimming, the forelimbs and hind limbs cling to the sides of the body and move forward by bending the trunk and tail.

Giant salamander, commonly known as giant salamander, is a national second-class protected aquatic wild animal and a key development variety of agricultural industrialization and characteristic agriculture. It is a wild animal protected by genes. For more than 20 years, the giant salamander has not yet achieved large-scale reproduction. In this regard, we have deeply studied the basic theories of developmental biology, developmental neurophysiology and reproductive biology of giant salamander. Using modern molecular biology, genetics and other new technologies, the breeding technology of giant salamander was innovated, and the large-scale breeding of giant salamander was realized, which provided a technical platform for the protection and proliferation of giant salamander resources.
Why is the giant salamander also called the giant salamander?
A popular saying is that the giant salamander sounds like a baby crying and is shaped like a fish, so it is called the giant salamander.
Why is the giant salamander not a fish?
The scientific name of giant salamander is giant salamander, which is a precious wild animal and a specialty of our country. Because it cries like a baby crying at night, it is commonly known as "giant salamander". It is not a fish, but a fish. It is the largest amphibian in China. It looks a bit like a gecko, with a body length of about 1 m and a maximum length of 2 meters. Its head is wide and flat, and there are obvious warts on the surface. Small eyes, located at the back of the head and without eyelids, are the result of long-term adaptation to underwater life and degradation. The arc-shaped oral fissure is very wide, and there are many fine teeth of similar size in the upper and lower jaws, which is beneficial to feeding. The body is broad, flat and strong. The flat tail is very long, one-third to one-half of its body length, and it has fins up and down. The limbs are fat and short, much like baby's arms, which is said to be another reason for calling it giant salamander. There are 4 fingers on the forelimb and 5 toes on the hind limb, with webbed fingers (toes) and no claws. The body surface plate is smooth, scattered with small wart particles, and when it meets * * *, it can secrete white mushy mucus, which tastes like pepper. There are longitudinal pleats along the armpits and crotch of the body. The color of the body changes with the color of the living environment. The back is brown, reddish brown, dark brown, etc. It has dark irregular spots and its abdomen is light brown or grayish white. It can breathe with its lungs, but because its lungs are not well developed, like a frog, it needs a wet panel for gas exchange as an auxiliary breathing, so it must live in or near water. From the perspective of biological evolution, it is a transitional type from fish living in water to real terrestrial animals. Giant salamanders usually like to live under the clear stream rocks in the valley. In case of heavy rain or mountain torrents, it often leaves the water and sometimes climbs up trees. Specializing in fish, crabs, shrimps and frogs. , is a "bully" in the landscape. Sometimes it intimidates pedestrians and even hurts people. So Jinggangshan people also call it dog fish. During the Jinggangshan struggle, * * * used the giant salamander given to him by the masses in Mao Ping Bajiaolou to inspire and educate the people to rise up for revolution and overthrow the local tyrants and evil gentry. Jinggangshan is a paradise for giant salamanders, with many springs and clear and cool water. It often lurks in a cave with clear water during the day, swims out of the cave at night and opens its mouth to running water. Let fish, shrimp, insects, frogs and other foods flow into Zhuang village as a way to find food. "Shan Hai Jing Bei Shan Jing" once wrote: "There are many mermaids, which are fish-shaped, four-footed, and sound like babies, and can eat without being crazy." Giant salamanders are widely distributed in the middle and lower reaches of the Yellow River, the Yangtze River and the Pearl River and their tributaries, all over Beijing Huairou, Hebei, Henan, Shanxi, Shaanxi, Gansu, Qinghai, Sichuan, Guizhou, Hubei, Hunan, Anhui, Jiangsu, Zhejiang, Jiangxi, Fujian, Guangdong and Guangxi. There are many "giant salamanders" in China ancient books. It can be seen that the shape and living habits of the giant salamander have long been known to our people, and the name of the giant salamander has been passed down to this day. Among amphibians, the living environment of giant salamander is unique. Generally, they live in mountains, rivers and lakes with fast water flow, cool water quality, lush aquatic plants, many cracks and caves. Sometimes, it moves on the roots of trees or fallen trunks on the shore, and chooses caves with backflow at the mouth of the beach. There is usually only one cave. The depth of the hole is different, the hole is slightly larger than its body, the hole is spacious, there is enough space for it to swing, and the bottom of the hole is relatively flat or has fine sand. During the day, they often hide in caves with their heads facing outward, which is convenient for them to move at any time, prey and avoid the enemy. When disturbed, they quickly leave the cave and go to the middle reaches of deep water. Come out for activities and hunting in the evening and evening. When swimming, the limbs cling to the abdomen and move forward by swinging the tail and flapping the body against the water. It is fierce when it preys, and often waits for opportunities among the rocks at the mouth of the beach. When it finds the prey passing by, it will suddenly open its mouth and swallow it, and then send it to its stomach to digest it slowly. So the allegory in some places: "Giant salamander sits at the mouth of the beach and likes to eat by itself" refers to this. Adults eat a lot, including fish, frogs, crabs, snakes, shrimps, earthworms and aquatic insects, and sometimes they eat birds and mice. Interestingly, it is also good at catching a stone crab hidden in a crack in a stream with one trick. It uses the characteristics that the two big pincers of the stone crab can't loosen things easily, and puts its tail tip with foul secretion into the gap to lure the stone crab to use pincers. Once the stone crab is found to be "trapped", it will be pulled out immediately. Due to slow metabolism, food is scarce. ......
