What venomous reptile's genus name Ophiophagus means 'snake-eater'?

The venomous reptile whose genus name Ophiophagus means “snake-eater” is the king cobra.

The name reflects the king cobra’s diet: it commonly hunts and consumes other snakes, including rat snakes, pythons and sometimes other venomous species. Its scientific name is Ophiophagus hannah, with Ophiophagus formed from Greek roots meaning “snake-eater.”

Despite its common name, the king cobra is not a true cobra in the genus Naja. It belongs to its own genus, Ophiophagus, and is native across much of South and Southeast Asia. It is the world’s longest venomous snake, although length varies considerably among individuals and populations.

The species is also notable for building and guarding a nest, an unusual behaviour among snakes. Its hood resembles that of a cobra, but its size, diet and evolutionary relationships distinguish it from the better-known spectacled and monocled cobras.
