Some of the synonyms for Ophiophagus Hannan include Hamadryad, Maha Naja, Hamadryad Cobra, and King Snake. The name "king cobra" is derived from the fact that it's the largest venomous snake in the world, and it's often referred to as the "king of snakes." The Latin name Ophiophagus Hannan literally means "snake eater," indicative of its diet, which mostly consists of other snakes. Despite its deadly venom, the king cobra plays a vital role in the ecosystem, as it helps to control the population of other venomous snake species.
