IMPORTANT: Many snakes have significant variance in coloration and pattern even within the same species. There can also be extreme differences in appearance from juveniles to adults so it is important to never assume you have properly identified a snake.


40 to 50+ cm in length, the Chinese Mountain Snake is a small species with a grayish black head that transitions sharply to a tan neck. Body color transitions seamlessly from tan at the head to reddish brown, then brown, then dark grayish brown at the tail. A faint dorsal stripe can be seen on most specimens starting from the head and fading off in the first third of the body. Color transition from head to neck also delineated by thin white or yellow band. 


Active mostly during the day the Chinese Mountain Snake is a docile hunter of small lizards. As a result it is found near but not living in water. Generally move quickly when approached and may squirm when handled but unlikely to bite and not known to musk much. Very quick when startled despite its normally slow paced movement.

NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: Given its small size it could be mistaken for juvenile species of several snakes, but generally unique in appearance and temperament. It should be noted that small snakes can be particularly dangerous due to difficulty in properly identifying them and difficulty handling them. As such they should never be handled or approached.
