What is the maximal age a Mountain beaver reaches?
An adult Mountain beaver (Aplodontia rufa) usually gets as old as 10 years.
Mountain beavers are around 30 days in the womb of their mother. When born, they weight 23 grams (0.05 lbs) and measure 4.7 cm (0′ 2″). As a member of the Aplodontidae family (genus: Aplodontia), a Mountain beaver caries out around 2 little ones per pregnancy, which happens around 1 times a year. Fully grown, they reach a bodylength of 30.7 cm (1′ 1″).
As a reference: Usually, humans get as old as 100 years, with the average being around 75 years. After being carried in the belly of their mother for 280 days (40 weeks), they grow to an average size of 1.65m (5′ 5″) and weight in at 62 kg (137 lbs), which is obviously highly individual.
The mountain beaver (Aplodontia rufa) is a North American rodent. It is the only living member of its genus, Aplodontia, and family, Aplodontiidae. It should not be confused with true North American and Eurasian beavers, to which it is not closely related.
