| Sample size | large |
| Data quality | high |
| Observations | These animals have been estimated to live up to 25 years in the wild [0542]. Their maximum potential longevity has been estimated at 40 years [0434], though this has not been verified. Record longevity in captivity belongs to one male that was still alive at 33.5 years of age [0671]. |
