Lifespan, ageing, and relevant traits

Maximum longevity
Not yet established
Observations

There is a delayed implantation after fertilization [0443]. The actual embryonic development takes about 7 months, but the pregnancy usually lasts 1 year. In the wild, these animals have been estimated to live up to 22 years [0001]. Their longevity in captivity has not been studied in detail and hence their maximum longevity could be underestimated.
