Kraits come in many different flavors, there are 12 species in total and all of them are extremely deadly. The Common Krait with an average length of 3 feet (1m) is just one of these species; it can be found in the low scrub jungles of the Indian sub-continent. They prey on other snakes and can even turn cannibalistic. They are not aggressive toward humans even when provoked, they prefer to coil and hide their heads for protection. The bites are usually a result of close encounters in inhabited areas; sometimes these snakes chose to make human habitation their own.
The Krait venom is a neurotoxic cocktail that is both strong and deceiving. The bite affected zone if often painless which can lead to a false judgment of the seriousness of the situation. As in other neurotoxic venoms, the cause of death is suffocation from respiratory failure, usually 6 to 12 hours after the bite.
