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.

DESCRIPTION

Venomous. Variable in color and pattern but generally yellow, orange or tan in color with dark brown or black alternating blotches running the length of the upper back with similar colored markings along the side. Head is large and tall with small eyes and light stripes running along each side of the jaw. Head color is dark similar in color to a river rock helping with camouflage.

BEHAVIOR

Active at night usually well hidden in rock crevices. The Mountain Pit Viper is an ambush predator that will wait in a single position ready to strike. They are a viper and have relatively long retractable fangs and will bite readily at anything that comes within range when hunting for food, but not actively aggressive when encountered. Not prone to give chase but will hold their ground if they feel cornered, though will retreat quickly if the opportunity arises. A bite from a Mountain Pit Viper should be considered very serious and medical attention should be sought immediately. Although not known to be deadly serious damage can occur from a bite even if treated and complications can always arise.

HABITAT

Found at high elevations in or around streams and rivers and generally more active in the colder months. The Mountain Pit Viper is exceedingly rare in Hong Kong and due to its proclivity to hide out in rock crevices it is extremely difficult to find.

MISTAKEN IDENTITY

NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: The Mountain Pit Viper is unique in appearance and not easily confused with other species. If found observe from a safe distance. Visit the 'Practical Venomous Snake ID' section of the Snake ID page for tips on identifying some of the more common venomous species.
