Maximum longevity: 22.7 years (captivity)
Observations: They appear to attain adult weight at about 2 years of age. One captive female was sexually mature at 4 years of age (Ronald Nowak 1999), but anecdotal reports suggest they may become sexually mature at earlier ages. In captivity, one male was at least 22.7 years old when he died (Richard Weigl 2005). There is one report suggesting they may live up to 34 years (David Macdonald 1985), which is unlikely.
