Observations

With a 3.5 months period of delayed implantation, the total gestation lasts 11 months [0443]. In the wild, these animals have been reported to live up to 46 years [0542], which is plausible. Little is known about their longevity in captivity, but one wild born specimen was about 14.4 years old when it died in captivity [0671].
