Lifespan, ageing, and relevant traits

Maximum longevityNot yet established
Observations

It has been suggested that beavers may live as much as 50 years [0434], which is doubtful. Although the maximum longevity of this species cannot be correctly estimated, one specimen lived 13.7 years in captivity [0671].
