The genus Ophiophagus refers to a group of venomous snakes commonly found in Southeast Asia. These snakes are commonly known as king cobras, but other synonyms for the species include hamadryad, elapine, and serpent. The name Ophiophagus is derived from Greek, meaning "snake eater," as the king cobra is known to feed on other snakes. The species is known for its distinctive hood and large size, with adults sometimes reaching up to 18 feet in length. King cobras are highly dangerous to humans, with their venom being both potent and lethal. Despite this, the species is considered an important part of the ecosystem.
