- Sample size
- Small
- Data quality
- Acceptable
- Observations
In the wild these animals have been estimated to live about 3 years [0542], which may be overestimated. It has been reported that they live up to 4 years in captivity [0434], which is possible but unproven. One captive specimen that lived 2.9 years remains the record longevity for this species in captivity [0671].
