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, coconut crabs sometimes live longer than wild averages — though wild longevity reflects natural ecology.
Oldest recorded individuals
Long-lived coconut crabs are rare in the wild; research and zoo records help set upper limits for the species.
