Lifespan, ageing, and relevant traits
- Maximum longevity
- Not yet established
- Observations
The total gestation time probably includes a period of delayed implantation [0443]. In the wild, these animals have been estimated to live up to 23 years [0573]. Their longevity in captivity has not been studied in detail and hence their maximum longevity must be classified as unknown.
