pelage, hairy, woolly, or furry coat of a mammal, distinguished from the underlying bare skin. The pelage is significant in several respects: as insulation; as a guard against injury; and, in its coloration and pattern, as a species adornment for mutual recognition among species members, concealment from enemies, or, in the case of many males, as a sexual allurement to promote courtship and mating. Compare plumage.
