Lifespan, ageing, and relevant traits
- Maximum longevity
- Not yet established
- Observations
The total gestation time of about 10 months includes a period of delayed implantation [0443]. In the wild, these animals have been estimated to live up to 39 years [0434]. Their longevity in captivity has not been studied in detail and hence their maximum longevity remains unknown.
