Maximum longevity: 29 years (wild) Observations: There are unverified reports that these animals live up to 29 years in the wild (http://www.demogr.mpg.de/longevityrecords), though this could be due to confusion with earlier reports of a captive specimen living up to 28 years (Philip Altman and Dorothy Dittmer 1962).
