Polar bears normally live in extremely cold environment .They have fur with hollow bristles to insulate and trap warm air to protect themselves from external freezing low temperature and preserve the body heat. They also have thick layer of fat under their skin.
With any change in their habitat to a warm region they will either shed their fur bristles or may not be able to adapt the changed habitat and perish.
better to ask how did the ancestors of polar bears adapt.
1) a rapid but graduated change of fur color
2) extra size
3) most don't hibernate and are active looking for food all year round
females feast before denning but hibernating would reduce body temperature (seasonal changes awaken black bears)
4) they are able to alter metabolic rates during times of food scarcity (black bears too can do this but will have times when food is plentiful an hibernate for another period of the year)
5) bear eat a wide verity of food and are prepared to roam for it. Polar bears subsist mainly on mammals (but will eat vegetation during periods of the year when able to access tundra)
warm water proof fur that traps heat
white camofluage that helps them camofluage in the snow big teeth to eat snow things
Polar Bears have adapted to their current climate, but if you aresuggesting rehabilitation into the North American mainland, or warmer parts of the continent, the Polar Bears would refuse to eat any animals (this is because they are adapted to caribou, moose, elk, seal, and puffin) and die, or die from overheating.
Yes they are. Their feet have thick hair to prevent themselves from slipping
They have thick layer of fat to keep themselves warm
They have small ears to prevent heat loss
Polar Bears survive in the arctic with their extra layer of fat.
Their skin is actually black, under their white fur, to help keep in the warmth from the sun. They have short but sharp claws, and pads on their feet to help them keep a good grip on the arctic ice. They also have layers of blubber (fat) to keep them warm in the freezing environment.
Adaptation takes time, and is constrained by the physical attributes and needs of each animal, based on it's evolution. Polar bears are specialists, and all specialists are so adapted to their small niche that it takes a long time under the right conditions for them to survive a change. Polar bears adapted over generations to live in the far north, and in doing so they became all white, great swimmers, and capable of long periods without food. However, they also became more carnivorous than any other bear, and specialized on hunting seals and other marine life off ice. They can't swim fast enough to catch them without ice, they hunt them mainly as they come up holes in the ice to breathe, or when mothers and seal pups are on ice but under snow. There isn't sufficient foot for them on land - they can't run fast enough to kill caribou and can't get enough calories from plants to survive. They don't know what is happening to their ice, all they know is that food is scarce. They might try to kill any animal they can catch, but there isn't much else they can catch often enough to survive if the ice they use to hunt marine mammals is gone. Over time, if the ice continues to melt and they lose their habitats, they will go exinct, it's happening too fast to adapt. It's possible that as climate changes and habitats shift, brown bears will expand their range north and some will interbreed with polar bears. If their offspring survive, some polar bear genes will remain, but the species will be gone.
Blubber and a thick fur coat helps keep the polar bear warm.
It stores Heat inside of its fur. Although sometimes it doesn't work. Polar Bears are made for Antarctic environments.
the adapt in the winter when there is snow they blend in to the snow this helps them hunt.
The coloring of the polar bears helps camouflage themselves for hunting.
HELLO, polor bears adapt.
adapt
because sun bears are so use to being warm all year and polar bears can adapt better ( i reALLY DONT NO ?)
They adapt to cold weather (ice places)
I doubt it. Unless if they can find a really cold spot that the polar bears can adapt to, then possibly. Actually there are breeding programs at various zoos for polar bears.
thickcoat its animal instinct
their fur gets longer and darker
Polar Bears live in Alaska because it is one of the coldest and without ice and snow polar bears would have nowhere to live. Thick coats This answer is all wrong just type it in to google to find it out
Polar Bears , oxen , reindeer, cantalope
There are quite a few animals that don't adapt to living in the temperate zone. These animals include polar bears.
No, they do not. They are just able to adapt to water and snow really well, because that is the habitat in which they were born.
polar bears are related to bears.
