It is hard to guess what a American marten weights. But we have the answer:
An adult American marten (Martes americana) on average weights 878 grams (1.94 lbs).
The American marten is from the family Mustelidae (genus: Martes). It is usually born with about 31 grams (0.07 lbs). They can live for up to 19 years. When reaching adult age, they grow up to 38.2 cm (1′ 4″). Usually, American martens have 2 babies per litter.
As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.
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.
