What characteristic of the wolverine's thick, dense fur helps provide resistance to ice and frostbite?
Answer
It is oily
The wolverine's coat is engineered for extreme cold resistance, consisting of a thick, dense, two-layered structure featuring a woolly underfur and longer guard hairs. Crucially, this fur is also oily. This oily quality provides excellent insulation and imparts resistance to moisture buildup, preventing ice from forming directly on the coat or causing frostbite to the skin, which is essential for an animal that remains active throughout frigid conditions.
