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. 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 colourless and for many years, scientists worked on the theory that the individual hairs act as fiber 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 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.
Currently, no.
Humans are adopting arctic foxes because the climate that they live in is harsh and hard to hunt for food.
The difference between the fennec fox and the arctic fox it that the fennec fox lives in hot conditions, and the arctic fox live in colder conditions. Also, they don't look like each other, the fennec fox has large ears so it can loose heat fast from it giant span, and it is has a much smaller skeleton to the arctic fox. Also, the fennec fox is an gingery colour. The arctic fox has small ears so it doesn't loose as much heat so it can stay warm in it harsh environment, it has white fur, and a much bigger skeleton to the fennec fox.
Arctic fox ears have a compact shape and thick fur that help them retain heat in their cold habitat. Additionally, their ears are smaller than those of other fox species, reducing heat loss. These unique features help arctic foxes stay warm and survive in their icy environment.
Arctic foxes help control populations of small animals such as lemmings and Arctic hares.

Arctic foxes have several adaptations that help them survive in extreme cold environments. Their thick, multi-layered fur provides insulation, while their small ears reduce heat loss. They also have a unique ability to change the color of their fur from brown or gray in summer to white in winter, which provides camouflage against snow. Additionally, their compact body shape minimizes surface area, further conserving heat.
In the winter the Arctic Fox's coat turns white or blue-grey. This is to help the fox blend in with it's environment. The fox can then hide from predators and hunt prey without being detected.
They have smaller ears to conserve heat. Foxes from warmer areas have larger ears to help dissipate heat.
An arctic foxes fur changes color throughout the seasons; summer, their fur is brown or black, but in winter their fur is white. It's white, thick fur and fluffy white tail help it survive in their extreme environment.
An Arctic Hare freezes, hoping not to be spotted. Then, if it must, it uses speed to escape predators. It changes its brownish coat to a white coat in winter, to help it be less noticeable against the snow.
Polar bears have white fur which lets them blend in with the snow. They eat seals and other arctic animals. They also have a thick layer of fat to help insulate them from the cold.
