The King Cobra, found in India is the largest venomous snake in the world. In a single bite it can inject enough venom to kill an elephant - up to 6- 7 ml. This is enough to kill up to 20 people. The King Cobra is worshipped in India, particularly on the festive occasion of Nag Panchami and is depicted in sculptures on temple walls and celebrated in myth and legend. The venom of King Cobras has a paralyzing effect on the nerves and has been used to develop painkillers used to treat arthritis in humans.
