Salamander Fish Pinyin:ni, yu Basic Explanation:i.e. dollfish.

The giant salamander, also known as the dollfish, is classified as a national second-class key protected wildlife, and is also an "earth monument" earlier than the dinosaurs, which is called a living fossil. Dollfish have always been somewhat mysterious in people's eyes, and there are many rumors. So, what else do you not know about the dollfish?

Why is the giant salamander called a dollfish? One theory is that "its call sounds like a baby's cry". However, this claim has been rejected by academics.

Deng Xuejian, a professor at Hunan Normal University's School of Life Sciences, told reporters that the rumor of "screaming like a baby's cry" is a blackmail because the baby fish has no vocal cords and no vocal organs. "The sound people hear may be produced by eating and swallowing, or the physical sound made by spitting bubbles from underwater to the surface."

The giant salamander is known as a dollfish because of its chubby, short limbs, which resemble the hands of small dolls. Deng Xuejian told reporters that the salamander is called a dollfish because of its "similarity in shape" rather than its "similarity in sound".

In Zhangjiajie, the hometown of Chinese giant salamanders, the name "dollfish" has a better meaning. Due to the longevity of the giant salamander, up to 100 years of age or more, and its reproduction period of up to several decades, the folk legend of "the fish that sends the son", that is, there are more children and grandchildren, so the dollfish name has been passed on.
