Quick answer
Sun Bears (Helarctos malayanus) typically live around 20–25 years in the wild (longer in captivity). Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.

Sun Bear lifespan in the wild
Field and museum records place most sun bears near 20–25 years in the wild (longer in captivity). That figure blends ages at death across regions, so treat it as a planning range. Body size (25–65 kg (55–145 lb); males larger than females) and risk lifestyle both shape the average.
What shortens sun bear lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever sun bears share landscapes with people.
What helps sun bears 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.
Sun Bear 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 sun bears in the field.
Solitary habits and reproduction
Adults are largely solitary outside the breeding season. Females typically produce one or two cubs after a gestation of about three months. Cubs stay with the mother for up to three years, learning to climb and forage in dense canopy.
Conservation threats
Listed Vulnerable, sun bears face rapid habitat loss from logging and palm-oil expansion, plus poaching for gall bladders, paws, and the pet trade. Cubs are often taken after mothers are killed. Protected areas and anti-poaching patrols are critical across Malaysia, Indonesia, and Thailand.
