Quick answer
King Cobras (Ophiophagus hannah) typically live around ~20 years. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway
King Cobras (Ophiophagus hannah) typically live around ~20 years. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
King Cobra lifespan in the wild
Field and museum records place most king cobras near ~20 years. That figure blends ages at death across regions, so treat it as a planning range. Body size (about 9 kg) and risk lifestyle both shape the average.
What shortens king cobra lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever king cobras share landscapes with people.
What helps king cobras live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
King Cobra life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing king cobras in the field.
Nesting
King cobras are the only snakes known to build a nest for their eggs. The female gathers leaves into a mound, lays 20 to 40 eggs inside, and guards the nest until the young are ready to hatch, an unusual level of parental care for a reptile.
Conservation
King cobras are listed as Vulnerable, threatened by deforestation, collection for skins and traditional medicine, and persecution out of fear. Protecting the forests of South and Southeast Asia is key to their survival.
