''H. hypnale'' grows to an average of 30–45 cm in total length. The Armed Forces Pest Management Board states 0.4-0.6 m in total length.

Its build is that of a typical viperid with a stout body and a wide head. The snout is pointed and turned upwards, ending in a hump. The frontal, supraoculars, and parietal shields are large, but those on the snout are small and irregular.

The color pattern is grayish with heavy brown mottling, overlaid with a double row of large dark spots. The belly is brownish or yellowish with dark mottling. The tip of the tail is yellow or reddish.
Back off! Hump-nosed pit viper (Family - Hypnale Hypnale) - This snake species belongs to the venomous line of Pit Vipers, and is endemic to India and Sri-Lanka. They don't bear the strongest venom, but if their bite is untreated within a few hours, it can be potentially fatal to humans. Looking like dead tree barks / branches or even leaves sometimes, they are hard to spot, which increases the risk of getting bitten by them in the wild.

They are endemic to India and Sri-Lanka, and they live in wet and humid conditions. I clicked this image during my trek to Gerusoppa, Shimoga (Western Ghats) here in South India, where the lush green jungles are a bliss to eyes! Danger lurks in every footstep in such dense forests, and one must be extremely careful about every step they take. To make the matters worse, such places are usually Leech infested!

''H. hypnale'' is active during early morning and night. It spends the day in leaf litter and thick bushes. This species can be found on the stream side basking during the sunrise. Although it is a slow mover, it is capable of fast strikes. It has an irritable disposition and will vibrate its tail when annoyed, a behavior it has in common with other pit vipers, especially rattlesnakes of the genera ''Crotalus'' and ''Sistrurus''. It has been described as nocturnal, terrestrial, and aggressive when disturbed.
