Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. The king cobra is an elapid found predominantly in forests from India through Southeast Asia. This species is the world's longest venomous snake, with a length up to 18.5 to 18.8 ft. Cobras are famous for the threatening hood at their neck. They spread the hood out when they feel threatened or angry. Cobra is the Portuguese word for "snake".
