Habitat
Damp stream sides within rainforest; semi-aquatic
Range
Western Ghats, from Parambikulam Tiger Reserve in Kerala north to Kottigehara in Karnataka
The olive trapezoid snake, or olive forest snake, is endemic to the Western Ghats of India. After populations in Goa, northernmost Karnataka and southern Maharashtra were described as a new species, the water rhabdops, the known range of this species is from Parambikulam Tiger Reserve in Kerala north to Kottigehara in Karnataka, and possibly slightly further (Wikipedia, general species account).
It is found on damp stream sides within rainforest, from Palghat in Kerala to the Malnad area of Karnataka. It is a docile, placid snake and is said to be semi-aquatic, feeding on small, soft-bodied animals, and is seen more often during the rains, by day or night.
