The checkered keelback, or Asiatic water snake, is a common species of the water snake subfamily, endemic to Asia. Adults may reach a snout-to-vent length of 1.75m. The dorsal scales are in 19 rows, strongly keeled except the outer rows, and two oblique black streaks, one below and one behind the eye, are nearly constant. It may lose its tail as an escape mechanism (Wikipedia, general species account).
It feeds mainly on fish, amphibians and arthropods, occasionally on rodents and amphibian eggs. Clutches are usually 30 to 70 eggs, though as few as four or as many as a hundred have been recorded, and the female guards the eggs until they hatch in 60 to 70 days. Each hatchling is about 11cm long. Its range includes Nepal.
