Their most striking feature was the thick, insulating coat, which could grow up to one meter in length in northern populations. The coloration was highly variable, ranging from deep russet to near-albino cream, although museum specimens tend to display a muted grey due to exposure to early [preservation solvents](/entries/preserv…
