King Cobras

The king cobra (Ophiophagus hannah) is a species complex of snakes endemic to Asia. With an average length 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.

Individuals have diversified colouration across its habitats, from black with white strips to unbroken brownish grey, although after taxonomic re-evaluation, it is no longer the sole member of its genus but is now a species complex; these differences in pattern and other aspects may cause the genus to be split into at least four species, spread across its large geographic range.
