Lifespan, ageing, and relevant traits

Maximum longevity
Not yet established
Observations

It has been reported that females may live up to 22 years in the wild [0538]. Others have reported that moose can live up to 27 years in the wild [0001], which is plausible but unconfirmed. Record longevity in captivity is 18.4 years [0671]. Due to these conflicting reports, the maximum longevity of this species is classified as unknown.
