Ophiophagus

Ophiophagus is a small genus of venomous snakes in the family Elapidae. It contains the king cobra, Ophiophagus hannah, the sole extant species in the genus. The genus name comes from Greek words meaning “snake” and “eater,” reflecting its habit of feeding on other snakes.

Ophiophagus hannah is the longest venomous snake in the world, with reported lengths up to about 5.5 meters (18 feet). Adults typically reach 3–4 meters. The species has a distinctive hood when threatened and varies in color from olive green to brown or black with pale cross-bands or chevrons.

Its range covers parts of South and Southeast Asia, including the Indian subcontinent and southern China, with habitats spanning forests, mangroves, and agricultural areas. It prefers dense vegetation and proximity to water and is often found near human activity where prey is abundant.

The king cobra’s diet consists mainly of other snakes, including venomous species, but it will also eat lizards, rodents, and birds. It is generally shy and will retreat if given space. Reproduction is oviparous; the female lays a clutch of about 20–40 eggs and often guards them during incubation, which lasts roughly 60–90 days until hatching.

Venom is primarily neurotoxic and can be deadly to humans; bites require prompt medical attention and antivenom. The species is listed as Vulnerable by the IUCN due to habitat loss, persecution, and collection for the wildlife trade in parts of its range.
