Polar bears are well adapted for survival in the Arctic. Their adaptations include: a white appearance – as camouflage from prey on the snow and ice. thick layers of fat and fur – for insulation against the cold.
Do polar bears have special fur?
Polar bears have white fur so that they can camouflage into their environment. Their coat is so well camouflaged in Arctic environments that it can sometimes pass as a snow drift. Interestingly, the polar bear’s coat has no white pigment; in fact, a polar bear’s skin is black and its hairs are hollow.
What adaptations help polar bears eat?
Most bears are omnivores and do eat plant matter. But where polar bears live, there is almost no plant matter available, so they have adapted a totally carnivorous lifestyle. Their long, sharp claws help them pull seals right out of the water when they surface to breathe and onto the ice where the bears can feed.
How do polar bears adapt to climate change?
While polar bears have shown some ability to adapt to changes in their surroundings – for example, by foraging for food on land – scientists project polar bears will become more food-stressed as sea ice diminishes and populations will decline. … There are other impacts of climate change on polar bears, too.
What are the adaptations of polar bear for Class 7?

What helps a polar bear survive?
Inhabiting the ice and sea of the Arctic, polar bears are well-equipped for survival in a harsh environment. Two coats of fur and a thick layer of blubber help insulate the polar bear’s body from the cold, keeping its temperature at an even 37° C (98.6° F).
What adaptations help polar bears maintain constant internal temperature?
Thermoregulation. Body temperature, which is normally 37°C (98.6°F), is maintained through a thick layer of fur, a tough hide, and an insulating fat layer (up to 11 cm or 4.5 in. thick).
Why do polar bears need ice floes?
If the sea ice melts too much, it will not support their weight as they wait for seals to come out of the water. If the sea ice melts too early, they will not be able to hunt at all when they come out of hibernation. With the decreasing ice, polar bears are having to swim farther distances to move from floe to floe.
