!The common krait
Description
The average length of the common krait is 0.9 m (2 ft 11 in), but it can grow to 1.75 m (5 ft 9 in). Males are longer than females, with proportionately longer tails. The head is flat and the neck is hardly visible. The body is cylindrical, tapering towards the tail. The tail is short and rounded. The eyes are rather small, with rounded pupils, indistinguishable in life. The head shields are normal, with no loreals#Herpetology); four shields occur along the margin of the lower lip; the third and fourth supraoculars touch the eye. The scales are highly polished, in 15–17 rows; the vertebral row is distinctly enlarged and hexagonal. Ventrals number 185–225 and caudals 37–50, and are entirely intact. Their coloration is generally black or bluish-black, with about 40 thin, white crossbars, which may be indistinct or absent anteriorly. Albino specimens can be found, although such cases are extremely rare. The pattern, however, is complete and well-defined in the young, which are marked with conspicuous crossbars even anteriorly; in old individuals, the narrow white lines may be found as a series of connected spots, with a prominent spot on the vertebral region. A white preocular spot may be present; the upper lips and belly are white.
Distribution and habitat
The common krait is widely distributed across South Asia, including India, Pakistan, Bangladesh, Sri Lanka, Nepal and possibly Bhutan. Its range extends westward into Afghanistan and potentially parts of Iran. Within India, it is found throughout the country including the Andaman and Nicobar Islands.
