Chinese giant salamander, commonly known as baby fish, is an amphibian that lives in freshwater. It is a rare wild animal that is a specialty of China. It is commonly called "baby fish" because its nighttime cry is like a baby crying, but it is not a fish, but the largest amphibian with a body length of 1 meter. Around, the longest can reach 2 meters, weigh 20-25 kg, and the largest can reach 50 kg. The body color varies with the color of the habitat. The back is brown, reddish brown, black brown, etc., with darker irregular spots on the top, and light brown or off-white on the ventral surface.

Chinese giant salamanders live in clear, low-temperature streams or natural caves, living in mud or dark cracks in rocks. Generally in rapid water flow, cool water quality, lush water plants, rock cracks and caves in mountain streams, rivers and lakes, and sometimes also activities between the roots of the trees on the bank or on the fallen trunks, and choose the caves at the mouth of the beach with return flow Inhabited, there is generally only one per cave. The depth of the hole is different, the mouth of the hole is slightly larger than its body, the inside of the hole is spacious, there is enough space for it to maneuver, and the bottom of the hole is relatively flat or has fine sand.

Chinese giant salamanders often hide in caves during the day, with their heads facing outwards, allowing them to move at any time, hunting and avoiding enemies. When disturbed, they quickly leave the cave and swim into the deep water. Come out in the evening and at night to move and hunt. When swimming, the limbs are close to the abdomen and move forward by swinging the tail and body. It is very fierce when preying. It often waits in the rocky beaches. When it finds the prey passing by, it suddenly opens its mouth wide and swallows it, then sends it to the stomach to slowly digest.

The adult Chinese giant salamander eats a lot of food, including fish, frogs, crabs, snakes, shrimps, earthworms and aquatic insects, and sometimes eats small birds and rodents. What's interesting is that it is also good at catching a kind of stone crab hidden in the cracks of the rocks in the stream. It uses the characteristics of the stone crab's two big claws to clamp things and it is not easy to loosen, and it will have its own tail with fishy secretions. The tip reaches into the cracks in the stone, enticing the stone crab to use its claws to clamp. Once the stone crab was found to be "in the game", it was immediately pulled out.

Due to the slow metabolism of the Chinese giant salamander, its hunger tolerance ability is very strong when food is lacking, and sometimes it will not starve to death even if it has not eaten for 2-3 years. Activities gradually decrease from September to October. In winter, they hibernate under large rocks deep in caves or deep water, usually for up to 6 months, until they start activities in March of the following year. But it can't sleep deeply and can still crawl when frightened.

The wild population of Chinese giant salamanders is extremely rare, and they are mainly found in tributaries of China's Yangtze, Yellow and Pearl River basins above 1,500 meters above sea level. Giant salamanders are widely distributed, with traces of them in the middle and lower reaches of the Yellow River, Yangtze River and Pearl River and their tributaries, covering Huairou, Hebei, Henan, Shanxi, Shaanxi, Gansu, Qinghai, Sichuan, Guizhou, Hubei, Hunan, Anhui, Jiangsu , Zhejiang, Jiangxi, Fujian, Guangdong and Guangxi provinces and regions. In 1988, "The Wildlife Protection Law of the People's Republic of China" listed it as China's second-level key protected wildlife and is one of China's national treasures.
