Observations

Young females have an over 90% survival in the wild, though an increased mortality with age has been reported for both males and females after about 8 years of age [0800]. It has been reported that these animals live up to 24 years in captivity [0573], which could be overestimated. Record longevity in captivity is 20.6 years [0671].
