Lifespan, ageing, and relevant traits
- Maximum longevity
- Not yet established
- Observations
While females may reproduce much sooner, males generally do not mate in their first year of life. It has been estimated that these animals live up to 4 years in the wild [0542]. Record longevity in captivity, however, is only 3.1 years [0671]. Further studies are necessary.
