American martens are 1.5 to 2.2 feet in length, not counting their tail which can grow 5 to 8 inches long! Their weight varies by age and location, but adults weigh 1 to 3 pounds. Male and female American martens have a similar appearance, but males are about 15% greater in length and up to 65% larger in weight!
The color of an American marten’s coat depends on the geographic location; their main color can range from pale yellow all the way to almost black. Consistent with each subspecies is having a lighter-colored face and darker limbs and tail. All American martens also have coloration on their chest and throat ranging from a creamy yellow to vivid orange.
Other telltale characteristics of an American marten are its short legs on its long, slender body, triangular head, pointed nose, and large round ears.
