Description

The Dog-faced Water Snake can grow up to 127 cm in total length (Das, 2010). The head of Dog-faced Water Snake is slightly distinct. Its shields are large and sometimes fragmented. The small eyes with vertically elliptical pupils are located rather close to the snout. The stout body is cylindrical, the scales are strongly keeled and the ventrals are smooth. It possesses greyish body with brownish or olivaceous above, with more or less distinct dark spots or crossbars. A black streak passes through the eye to the neck. The belly is both yellowish and heavily mottled with black or almost entirely dark grey. It feeds on fish like mudskippers and gobies (Das, 2010). It inhabits mangroves, brackish river mouths and occasionally freshwater far inland.
