Observations	These endangered animals probably live around 4-5 years in the wild, though some may live up to 9 years [0542]. One captive specimen lived 17.3 years [0671]. Maximum longevity could be slightly underestimated because the better studied Himalayan tahr (Hemitragus jemlahicus) can live for more than 20 years.
