The polar bear population is divided into 19 discrete subpopulations. The global population is poorly studied partly because polar bears have a territory too wide to cover. White bears are not territorial which is why they are present in isolated population in some remote areas. The question as to how many polar bears are left in the world is still

They conclude that polar bears rely on sea ice so much so that they cannot live without the it. They will move with the ice. However the bear’s movement is not so random as scientists previously thought nor do they
Continue ReadingThe typical range of an average temperature in polar bears is around 36.5 – 38.8 °C (97.7 – 101.8 °F). They are thought to use numerous physiological and behavioral mechanisms to normalize temperature. However recent findings indicate that the ice bears find it difficult to slow down their metabolism during summer when the food is scarce. The pregnant female bear

The initial stages are quite critical since bears are more likely to be vulnerable than the advanced phases. The bear has a complicated life cycle and scientists faced extreme difficulty in studying it because one-third

Scientists aren’t sure which one is bigger. Biologists also refer polar bear as a marine mammal because the bear spends so much of its time in water. Polar bears love to

Their adaptation to stay warm in an unbelievably cold temperature is something that makes them matchless in the mammalian world. Thanks to its insulating ability, white color, and dense fur that not only makes the bear warm but also camouflages her in the arctic ice. The thick and fuzzy
Polar bears have long been the victims of human hunting. Humans hunt bears for several purposes such as sports, trading in skin, fur, polar bear trophy, or simply for polar bear food. The international agreement says that only the native people are allowed to hunt polar bears. It’s up to the indigenous people if they want to kill white bears

Polar bear hibernation does not occur like black bear or grizzly bear hibernation. Black and grizzly bears, unlike polar bears, are true hibernators. Polar bears probably do not hibernate in a way other mammals do. They just enter into a specialized winter dormancy. This is little different from natural hibernation. During winter dormancy polar bears can also reduce their heart

Through this blog I am not only going to initiate the debate over polar bears—in fact I’ll be looking forward to initiating genuine wisdom and perspective on polar bears. The polarbearfacts.net is a project which is designed to educate just about everyone including teachers, scholars, students, kids, and laymen but, above all, the polar bear lovers!
