The Dog-faced Water Snake is the most common snake found in our mangroves. Its eyes are small and situated on the top of its head close to the snout. Its head is distinct from body, with oblique black stripe at its rear eye margin. It is olive grey above with irregular narrow blackish bars and spots. Its scales are strongly keeled. Its underside is yellow mottled with black.

It is recently reclassified as Cerberus schneiderii, a species restricted to South-eastern Asian and Philippines.
