Giant salamander, the scientific name of giant salamander, is called "living fossil" at the same time as dinosaurs 300 million years ago. Wild giant salamander is a national second-class protected animal. Due to the excessive killing in the 1990s, it is difficult to see the wild giant salamander now, and all the giant salamanders on the market are farmed artificially. As a carnivore, giant salamander loves to eat fish, shrimp, snakes and birds, and has extremely high ecological requirements: the water quality should be fresh and clean, the dissolved oxygen content should be high, and the PH value should be neutral; The water temperature should be strictly controlled and kept between 16~22℃; The environment requires quiet, cool, lush trees and sparsely populated.

Writer Gu Qingsheng lived in seclusion in Shennongjia for more than ten years, exploring animals and natural environment. He recorded the little fish for several years, but he didn't record its crying. There are two records in Shan Hai Jing Bei Shan Jing: "There are many fish in the water, and the fish is the head of a dog, and its sound is like a baby, so it is eaten wildly." "There are many mermaids who look like fish and have four feet. It sounds like a baby, and it is not stupid to eat it. " Mermaid is what we call giant salamander today. This means that there are many fish in the water. They have a fish's body, four feet and a dog's head. It makes babies cry, and people can cure madness by eating its meat.

The giant salamander is not crying, but it sounds like a baby crying. It is precisely because its cry is similar to that of a child that it is called giant salamander. In fact, it is not a fish, but an amphibian salamander, which appeared long before dinosaurs. It has high scientific research value. Some giant salamanders can be seen in some rivers in China and Japan, far exceeding their close relatives living in America, and the most famous one is the giant salamander, which is what we often call "giant salamander". This kind of salamander is close to adults and has hardly changed for millions of years. It smells of pepper, moves unexpectedly quickly and cries like a baby.
