Lifespan, longevity, and ageing
Maximum longevity: 55 years (captivity) Observations: Longevity has not been studied in detail in these animals. One study in the wild estimated that one female could have died at 45-50 years of age (Furuichi et al. 1998). One wild born female has lived 50.1 years at Antwerp Zoo and could be up to 55 years old (Richard Weigl 2005).
