Red Necked Wallaby

Maximum longevity: 15.2 years (captivity) Observations: These animals have been reported to live up to 19 years (Fisher et al. 2001), which is not impossible but appears a bit dubious. Estimates of animals living 18.6 years in the wild have been reported (Ronald Nowak 1999). There are also anecdotal reports of some animals living more than 20 years. These are common animals in zoos, however, and record longevity in captivity is only 15.2 years (Richard Weigl 2005). Further studies are necessary.
