Lifespan, longevity, and ageing
Observations: In the wild, these animals are believed to live for more than 30 years (Ronald Nowak 2003). Their longevity in captivity has not been studied in detail, but one specimen was still alive at about 16.3 years of age (Richard Weigl 2005). Gestation does not include the 4-month delayed implantation period.
