Bears do not change their fur for the winter.
Polar bears have blubber, which is like extra fat, under their fur and that helps to keep them warm during the winter. They also grow out their winter fur coats to keep themselves warm during the winter.
there fur and dens.
the polar bears fur sits down flat in summer in winter their fur is all fluffed up
Their fur does not change colour, once it is a certain colour, it stays that way. However my huskies do change shades. During the winter their fur becomes very light, a bright shade and during the summer their fur gets darker.
A bear's metabolism slows to almost nothing during hibernation. Active bears do grow extra layers of hair during cold weather and the "winter fur" does grow faster than the normal summer growth.
A mule deer's fur turns color in winter.
bears are mammals that have a coating of thick fur during hibranation
The snowshoe hare changes its fur to white in the winter, and back to brown (with a white underbelly in the summer. If it is an outdoor rabbit, it can get sunburn, if it's black, its fur will turn a brown color, it isn't really dangerous, but make sure they have shade, and the color will become normal again after she/he gets their winter coat
For Camoflauge During Winter.
the tiger need to have a thick coat of fur, it fur has to change colors during winter, accept any animal its prey
I'm not completely sure on this one, but I think they keep warm by their fur. That's the only logical answer I can think of. Hope this helps!
yeah bears have fur....i think
