Russell's viper is a highly venomous snake of the family Viperidae, native to South Asia. The snout is blunt, rounded and raised, the crown of the head is covered with irregular, strongly fragmented scales, and the back scales are strongly keeled, with only the lowest row smooth. It grows to a maximum body-and-tail length of 166 cm and averages about 120 cm in mainland Asia (Wikipedia, general species account).
In India it is described as abundant in Punjab, very common along the west coast and its hills and in southern India, especially Karnataka, and north to Bengal, but uncommon to rare in the Ganges valley, northern Bengal and Assam. It is on the ground and forages mainly at night. Mating is generally early in the year, young are born from May to November, mostly in June and July, and it is a prolific breeder. Generally it is not found at altitude.
