It is not the fur that insulates the polar bear. The polar bear's skin is black, so it absorbs heat and keeps heat inside the body. The white fur is merely for camouflage.
Hibernate ; and certain ones do use camouflage...like polar bears for example.
The prey cannot see the Polar bear approaching, it gives them the element of surprise, If the bears were black or brown like their counterparts, animals that they hunt would spot them a mile off
since polar bears live in snowy regions their white fur blends in with the snow
Polar bears are naturally white, which helps them camouflage in their Arctic habitat, blending in with the snow and ice. However, if they were to adapt to a different environment, such as a forest or rocky terrain, a brown or greenish color would be more effective for camouflage. This adaptation would help them avoid detection by prey and reduce visibility to potential threats.
