The king cobra is the largest venomous snake in the world. Despite their large size and fearsome reputation, they aren’t aggressive and will avoid confrontation when possible. When in a threat display, king cobras can raise the anterior part of their bodies 3 to 4 feet off the ground and are able to follow an enemy in this position over considerable distances. King cobras are also the only snakes known to make a nest. They have better vision than many snakes and can see a moving person 300 feet (the length of a football field) away.
