Polar Bears

Polar bears require huge amounts of energy to maintain their body temperature in the cold, and they must build up fat reserves to do that. Seal blubber is optimal food source for them because their blubber is so rich in calories and fat.

With the exception of pregnant females, polar bears do not hibernate. Instead adult male polar bears and non-pregnant females remain active throughout the year. They nap during the day and sleep 7 to 8 hours a night.

Yes, polar bears are EXCELLENT swimmers. They can swim for Miles at a time. They travel to "better" locations to hunt for food. When there is open water between them and their destination, they swim.

Their favorite food, the Seal, however, can outswim a polar bear, or dive deep to evade them. So it would be very rare for a bear to catch a Seal in the water. They usually surprise a Seal at its breathing hole.

To begin with and because it's the most important reason, because like you and me they are living beings. They fight for survival in a declining environment. Polar bears are at risk every day. Due to global warming and hunters, seal populations are low. Which causes the bears to enter villages in search of food, which often ends in the bear being shot and killed. Not only is their main source of food diminishing but also their natural habitat. The polar ice caps and ice fields in the North are receding due to global warming. If you were starving and your home was disappearing would you want people to question whether you deserved ot live?

Nothing! Nothing! You leave them alone and let them live in peace! Bears are my favorite animals and I don't want them harmed in any way! You don't use Polar Bears for anything. You just let them be. I mean what if someone came and used you for something. You wouldn't be happy. Think of the thing you hate doing. Now imagine you were forced to do it. And if you hurt the bears they will attack. Bears are more afraid of you than you are of them. They attack because they think YOU will attack. Also do not bother bears with cubs. If you do they will attack! I mean they will scratch you face off! They are protecting their babies. I mean you would too. So, just leave them be.

Cats and bears are very different. A polar bear and a cheetah are different colors and different sizes. A cheetah runs much faster than a polar bear.

They're not that common. There appear to have been none so far this, and one last decade, a woman at a Berlin zoo. There were four attacks that resulted in two deaths in the '90's, and three in the '80's, two of these were in New York City zoos.

The female polar bear gives birth to one or two young while hibernating in a den dug into the snow. The young stay with their mother until they have grown up enough to hunt and survive on their own.

No. They are omnivores, that is, they eat anything, but they prefer seal.

No, but leaders of The Five Polar Nations are seriously concerned that the species may not survive to see the century. .

On April 15, 2011, Vladmir Putkin notified the Associated Press that Russia is banning its 2011 Polar bear hunt. That's a bandwagon we should ALL be on.

polar bears are white bears that aresometimes dangerous but people like them any ways

Not only would it deprive future generations of a beautiful creature, but it would leave a hole in the food chain of the regions the polar bear now inhabits. The seal population would grow without their numbers held in check by the normal cycle of hunting by polar bears. They in turn would hunt the oceans of their ranges in ever increasing numbers. This would create a strain on their food source, which could cause a collapse of their food supply, which could cause them to become extinct, or if another species already under strain from other factors is unable to compete for the limited food, they in turn could become extinct. All species, including ourselves are inter-related, as with dominos, when one falls it has effects on all the others near it. Some are easy to see, as with the seals, but some are far reaching and much harder to see or anticipate.

Polar bears have only one enemy MAN, they can only escape by diving into the sea.

it can maintain to help survive

their called a herd

There are no polar bears in the wild in Argentina. There may be some in zoos, where they'll eat whatever meat they are fed by their keepers.

These bears are though to live no more than 15 to eighteen years, but new tagging devises have allowed biologists to find a few bears that are in their early 30's. This has lead to some dispute about what age they will live to in the wild. In captivity the generally live a lot longer and reach mid to late 30's. One polar bear in a London zoo lived to the ripe old age of 41 years old!

Each polar bear litter has 2 cubs and sometimes even 3 cubs. Cubs weigh around 1 kilogram (2 pounds) at birth. They are totally helpless/defenseless at birth and depend entirely on their mother for food and protection. Cubs stay with the mother for around 2 to 3 years of their life and then go away.

Noses on a polar bear close up because they don't want to get snow up their noses when they is a snowstorm, Or they also close their noses so they don't get water up their noses when they are in the water.

The polar bear is still listed as a "Threatened" species on the Endangered Species Lists. The IUCN Red List Endangered Species List has the population trend listed in the 2011 List as "decreasing". They are losing habitat, being poisoned by mercury and other pollutants in their food sources (since they are at the top of the food chain in the region). The Arctic is warming and ice is melting which also threatens their free range to which they are so adapted, they could not survive abrupt changes to warmer climates. They are no longer being hunted for sport from planes and icebreakers due to an international treaty, but their habitat is shrinking and hunting "grounds" are melting.

They have big long guard hairs that protect them from the cold and under those they have a wool like hair called qiviut which is very warm and protects them from the cold. They have uniquely shaped hooves so that there are able to dig through the snow to get the forages (grasses) below. They get their food from the grasses below the snow and their water intake from the snow! Quite clever and environmentally adapt animal probably explains why they have been around for 1 million years!

Polar bears have thick fur so they can live in the cold of the arctic and swim in the icy sea. They also have a thick layer of insulating fat beneath their skin.
