Detailed explanation-1: -Warm winter coats Many mammals have specialized coats to ward off the winter cold. Caribou have hollow hairs that trap warmth close to their bodies. Muskoxen are so well insulated with underfur that they have little trouble with cold, even in the fiercest blizzards.

Detailed explanation-2: -Their white fur gets camouflaged against the white background of snow protecting it from predators and also helps them catch their prey. Two thick layers of fur act as an insulator protecting them from the surrounding harsh climate. In order to avoid getting overheated they move slowly and rest often.

Detailed explanation-3: -According to the National Park Service, there are three major strategies for animals, as well as insects and plants, to survive through cold temperatures: migration, hibernation and resistance (tolerance).

Detailed explanation-4: -These animals build up stores of fat to sustain and insulate them through the winter. They also have thick coats of fur for further insulation. Some save energy by hibernating during the long winter months. Others migrate to warmer climes during winter.
