In Mandarin, the word “mǎng” actually means python and “shan” is the word for mountain. The mountain range from which this species is endemic was given the name Mangshan due to its snake-like shape.Discovered for the first time in October 1989 in the Mangshan Mountains of the Hunan province of China, this pit viper does not spit venom, as has been speculated. Recent surveys have shown this species to be almost extinct in the wild.
