What is the maximal age a American marten reaches?
An adult American marten (Martes americana) usually gets as old as 19 years.
American martens are around 28 days in the womb of their mother. When born, they weight 31 grams (0.07 lbs) and measure 8.9 cm (0′ 4″). As a member of the Mustelidae family (genus: Martes), their offspring is 2 babies per pregnancy. Fully grown, they reach a bodylength of 38.2 cm (1′ 4″).
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 American marten or American pine marten (Martes americana) is a species of North American mammal, a member of the family Mustelidae. The species is sometimes referred to as simply the pine marten. The name “pine marten” is derived from the common name of the distinct Eurasian species Martes martes. The American marten differs from the fisher (Pekania pennanti) in that it is smaller in size and lighter in color.
