Why are polar bear coats thick?
Polar Bears have thick coats to keep them warm.
How can polar bears look white when they have black skin?
A polar bear's skin is black. The fur reflects light, making the polar bear appear white to us (the fur is actually somewhat transparent).A polar bear's skin is black so it can soak up as much of the sun's rays as possible. Polar bears have almost transparent fur over black skin. Reflection of the sunlight from the densely packed transparent hairs makes polar bears seem to be white. The bears' black skin absorbs heat from the sun. The seemingly-transparent fur is made up of hollow hairs called guard hairs. These air-filled guard hairs help transmit heat from the sunlight to the polar bear's black skin as a solar heat collector. In turn, the reflection stops the heat being lost from their black skin.The polar bear's fur seems colorless and for many years, scientists worked on the theory that the individual hairs act as fibre optics bringing sunlight directly to the skin. This has recently been proven to be incorrect, and the hairs are not truly transparent, but contain keratin. Viewed side-on, the hairs appear colorless; viewed lengthwise (as if one was looking down a telescope) the hairs no longer appear transparent.
Of what is a polar bear made?
Polar Bears have fur that is made up of "Hollow Guard Hairs". Now don't ask me what that is.......cause I coppied this answer off somewhere.

How does white fur help the Arctic foxes survive?
A polar bear does not actually have white fur. A polar bear's skin is black so it can soak up as much of the sun's rays as possible. Polar bears have almost transparent fur over black skin.

This has recently been proven to be incorrect, and the hairs are not truly transparent, but contain keratin. Viewed side-on, the hairs appear colourless; viewed lengthwise (as if one was looking down a telescope) the hairs no longer appear transparent. However, even though the hairs do not carry light to the polar bear's skin, they do carry heat.it helps them survive in the cold winters in antarctica and the white fur helps them to camouflage themselves when searching for prey.
How many wounds can a polar bear give you?
oh , that's simple. A polar bear can kill you.
Why doesn't the color of a polar bear's fur change?
it does change colour. Polar bears have fur that is made up of "hollow guard hairs." Sometimes when polar bears live in zoos that are in a warmer climate, they can have algae growing inside the hollow guard hairs of their fur. This makes them have a greenish tint to their fur. These hollow hairs also keep their hair from matting down when they swim in water. owned.
