Quick answer
Wild sperm whales typically live around 65 years, though predation, disease, and habitat quality shift the average.
Lifespan in the wild
Most sperm whales reach roughly 65 years under natural conditions. 60–70 years
Factors affecting longevity
Predators, disease, food scarcity, and human pressures all shape survival. Males and females may differ in average lifespan.
In captivity or as pets
With veterinary care and steady nutrition, sperm whales sometimes live longer than wild averages — though wild longevity reflects natural ecology.
Oldest recorded individuals
Long-lived sperm whales are rare in the wild; research and zoo records help set upper limits for the species.
