Quick answer
Beluga Whales (Delphinapterus leucas) typically live around 35–50 years in the wild. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway

Beluga Whale lifespan in the wild
Field and museum records place most beluga whales near 35–50 years in the wild. That figure blends ages at death across regions, so treat it as a planning range. Body size (700–1,400 kg (1,540–3,090 lb); males larger) and risk lifestyle both shape the average.
What shortens beluga whale lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever beluga whales share landscapes with people.
What helps beluga whales 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.
Beluga Whale 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 beluga whales in the field.
Diet and ecological role
Beluga Whales feed on carnivore — fish, crustaceans, worms, and cephalopods. Foraging shifts with season and local abundance. As mammals, they influence food webs — controlling prey, dispersing seeds, or shaping habitat through feeding and movement.
Conservation and coexistence
Listed as Near Threatened on the IUCN Red List. Habitat loss, hunting, and climate change threaten many populations. Responsible ecotourism and community conservation help in parts of their range. Never approach or feed wild beluga whales.
