Lifespan, ageing, and relevant traits
- Maximum longevity
- 2.2 years (captivity)
- Source
- ref. 671
- Sample size
- Small
- Data quality
- Acceptable
- Observations
In the wild, these animals have been estimated to live up to 2.5 years [0542], which could be overestimated. In captivity, they do not appear to live more than 2.2 years [0671], though some anecdotes indicate a longer lifespan.
