Lifespan, ageing, and relevant traits
- Maximum longevity
- Not yet established
- Observations
Unlike females, males only breed in their second year. Estimates based on the amount of tooth wear suggested that these animals live up to 4 years in the wild [0627]. Without more detailed studies maximum longevity is classified as unknown.
