King cobras, native to Asia, are the world's longest venomous snakes, typically reaching 10-12 feet, with a verified record of 18.7 feet in Malaysia. Despite potent venom, they are generally shy, using intimidation over aggression. While not true cobras, belonging to the Ophiophagus genus, they share hood-flaring behavior. Their diet primarily consists of other snakes, earning them the 'snake eater' moniker. Scientific fascination continues regarding their biology, behavior, and size limits.
