Kraits are boldly banded snakes found in grassland, scrub, and jungle of India and southeast Asia. They are primarily active at night. If disturbed, they are often reluctant to bite, balling up and hiding their heads inside their coils. Nonetheless, kraits are among the most dangerous snakes in India and south-east Asia in terms of total human fatalities. Kraits primarily eat snakes, but will occasionally take mice or lizards.
