DESCRIPTION

Mountain water snakes are light brown or olive green with brown saddles running the length of the body. The bands may be faded in adults along the spine but are well defined on the sides. Characteristic red or orange coloration between the bands on juveniles which fades as they reach maturity. A robust species when mature and can grow between 0.7-1m. Round pupils and a medium sized head and jaw relative to body size.

BEHAVIOR

Mostly nocturnal mountain water snakes come out at night to hunt fish and amphibians. They have also been observed out during the day in both early morning and at dusk. Quick to bite, musk, roll and squirm excessively but despite being defensive they are not considered dangerous to humans.

HABITAT

Found largely in the New Territories the mountain water snake is a less common snake to encounter in Hong Kong. Due to their diet of fresh water prey they can be found most readily near slow or swift moving and cascading mountainside bodies of water.

MISTAKEN IDENTITY

NO SNAKE SHOULD EVER BE HANDLED BY ANYONE BUT EXPERTS: Can be mistaken for some other aquatic snakes but generally not confused with venomous species.
