The king cobra is the largest venomous snake in the world, able to grow up to 18 feet long. It has a large hood and spreads it when threatened, along with raising up to 6 feet of its body off the ground. The king cobra's venom is powerful enough to kill elephants or 20 people. It preys on other snakes and lizards, hunting with its keen eyesight and sense of smell. Though facing threats from habitat loss and killing, the king cobra remains not yet endangered.
