Lifespan, ageing, and relevant traits
- Maximum longevity
- Not yet established
- Observations
Estimates that these animals live up to 14 years in the wild are likely overestimated [0542]. One study in the wild reported an average longevity for females of little over 4 years while males appear to live even less [0434]. Not much is known about their longevity in captivity, but one animal lived for 11.8 years [0671]. Because of these conflicting reports, maximum longevity must be classified as unknown.
