What unique structural attribute of the wolverine's oily and coarse fur prevents icing over in frigid habitats?
Answer
The oily quality prevents moisture from penetrating to the skin
A crucial adaptation for surviving in environments characterized by constant freezing temperatures and heavy snowfall is the composition of the wolverine's coat. The fur possesses an inherent oily quality. This characteristic actively repels external moisture, meaning water from snow or sleet cannot soak through to the skin or saturate the deeper layers of the pelt. Consequently, the fur remains light and insulating, virtually immune to the dangerous and energy-draining process of becoming weighed down or restricted by accumulated ice, which is a significant survival disadvantage for many other mammals in similar climates.
