The king cobra (Ophiophagus hannah) is a species complex of snakes endemic to Asia. With an average of 3.18 to 4 m (10.4 to 13.1 ft) and a record length of 5.85 m (19.2 ft), it is the world's longest venomous snake and among the heaviest. Under the genus Ophiophagus, it is not phylogenetically a true cobra despite its common name and some resemblance. Spanning from the Indian Subcontinent through Southeastern Asia to Southern China, the king cobra is widely distributed albeit not commonly seen.
