Do snakes like swimming? - Zoacys dhumnades

乌梢蛇 （拉丁学名：Zoacys dhumnades）俗称乌蛇、乌风蛇，为游蛇科，乌梢蛇属体形较大的无毒蛇，广泛分布于中国，国外未见有报道。生活在丘陵地带及山川小溪，狭食性蛇类，以蛙类(主食)、蜥蜴、鱼类、鼠类等为食。由于其栖息地破坏及人类大量捕杀，目前野外生存数量大减，应予保护。乌梢蛇可入药。乌梢蛇皮还是京胡与京二胡的专属用皮。具有黑如缎白如线的美感。现在逐步兴起仿生皮。以减少对蛇的捕杀。

Zoacys dhumnades, commonly known as the black snake and black wind snake, is a large non-venomous snake of the family Colubridae, which is widely distributed in China and hasn’t been reported abroad.Living in hilly areas and mountains and streams, it is a kind of stenophagous snake and eats frogs (staple food), lizards, fish, and mice. Due to habitat destruction and human hunting, the number of Zoacys dhumnades living in the wild is greatly reduced and should be protected. Zoacys dhumnades can be used as medicine, and its skin is a special material for Jing Hu and Jing Erhu. People love its skin for its beauty, black as satin and white as thread. Today, similar bionic skins are becoming popular on the market to reduce the killing of snakes.
