Polar Bears
Known scientifically as Ursus Maritimus, the polar bear is native to the Arctic Circle, and is the world's largest carnivore species found on land. It is classified as a vulnerable species, with 5 of the`9 polar bear subpopulations in decline. They have a reputation as the only animal that actively hunts humans, but in fact, anything they encounter is potential prey.

How do polar bears survive in zoos during hot weather?
They can survive even at warmer temperature because like all mammals they are warm blooded and, therefore, can adjust their body heat. At a certain point tho it's too hot for them. Many zoos or aquarium keep them in countries that have a warm summer and they are doing fine.
Where are most polar bears found?
"Polar bears live in extreme cold weather conditions. They are found around the North Pole. They also have their habitat in Tundra, Greenland and towards north side of North America, Europe and Asia."

A) The polar bear feels a threat towards themselves or their offspring.
B) Whilst searching for food, if they see potential "competition" they will vanquish the potential enemy in order to feed their young
I hope this has helped :)
Does the polar bear live in a cave?
Polar bears live in arctic regions where there are no caves, holes, burrows, or "dens" for them to live in. Polar bears are adapted to live in the open and spend nearly all their time ranging over ice and tundra (where there are no rock faces to host caves, nor earth for holes, burrows or dens to speak of).
Why do polar bears get hunted?
because the polar bears kill people (they have no right)
People are not killing them on purpose, it has to do with global warming. Rising temperatures are causing the ice caps to melt, removing the Polar Bears natural habitat. By reducing green house gasses and CO2 emissions, we could yet save their habitat in in turn, the creatures themselves.
Human Race are spreading terror allover the earth , Poler Bears are among the victims .
What can we do to help polar bears?
- We can help polar bears by buying fur that is made from other products, not polar bears.
- Also, we can help polar bears by not releasing the greenhouse gases that will cause global warming!
What are special features about the polar bear?
the polar bear is different from other bears. well its because polar bears are mostly found in the cold zones like Antarctica and other ones,while a bear that is brow lives in a den and on dry and very hot places that's why there skin is brown as the dirt and the polars skin is as white as snow.
Are polar bears nice to each other?
No not really, they are solitary animals most of the time. Mother and cubs and sub-adult males and females spend time together during a certain time of the year. Sub-adult males and females, and adult males spend considerable time interacting in social play, developing fighting skills and establishing hierarchy. Sub-adult males suffer the greatest death rate from starvation and from adult male bears, and are considered the most dangerous because they are not fully capable hunters and are more likely to be aggressive around human installations that may have easily available food.
Polar bears constantly travel in search of food, and cover such a large range that they don't have a territory. However, they are not social. Also, when mother polar bears encounter males, they will attack and drive them off in order to defend their cubs (polar bear males will kill cubs if they can because the female will be ready to mate sooner if the cubs die).
When will the polar bear be extinguished?
There are no complete, or "set in stone" answers. As the environment, and circumstances change, so do the time tables that researchers and scientists project. A recent report done by the U.S. Geological Survey done May 2008, projected that two thirds of the total Polar Bear population world wide, including Alaskan Polar Bears, could vanish by the year 2050. This was said to be a conserative estimate, considering the drop in birth figures and overall decline in the Western Hudson Bay, and Southern Beaufort Sea.
Do polar bears feel cold and if so how cold must it be?
Polar Bears are actually more in danger of over-heating then hypothermia. The Bear can swim in frozen ocean water with no ill-effect. To hunt Polar Bear the native have their sled dogs harrass them until the faint from heat exhaustion (doesn't really take all that long either), and then they walk up to them and harpoon them.
What do polar bears do all day?
The black bears here in Tennessee have cubs dependent upon the food supply. In the past two years the food has been abundant and the bears are having up to 4 cubs each. Typically the average bear has between 1-3 cubs.
Are polar bears white all around?
Yes. Bears that were colors other than white would not have been able to hunt for food in the arctic, and would have died off. Only white bears would survive. After a while, there are only white bears.
What is the symbiotic relationship for polar bears?
Bees and bears do share a symbiotic relations ship. Bees produce honey because of the pollen they collect. Bear apparently enjoy eating the honey, inducing the bees to make more honey for the hive.
What is the gestation period of a polar bear?
around 6.5 months After a successful mating, there is delayed implantation of about 6 months. The female has about 2 months to put on 440 lbs. of blubber before entering her maternity den. Gestation Embryonic growth is about 2 months but gestation is 240-270 due to delayed implantation. the average weight of a pregnant polar bear is 650 pounds to 730 pounds
The gestation period (time of pregnancy) for a bear is 180-270 days.
The exact/accurate gestation period is not known but it is around 8 months. Each litter has 2 cubs and sometimes even 3. Cubs weigh around 10 to 15 kilograms (22 to 33 pounds) at birth. Cubs stay with the mother for around 2 to 3 years of their life and then go away.
After mating there is a delayed growth period of about four months. This "delayed implantation" allows the mother time to acquire her full birthing weight, almost an additional 450 pounds on average, and then give birth during the best time of year for the cubs survival. The actual period for "embryonic development" is about four months. So, the total time from mating, and fertilization, to birth is right at eight months. For more details, see sites listed below.
How does the climate affect the polar bear?
Global Warming(Heating)---> Ice melting---> Less Place for Polar Bears to hunt and live---> Polar bears dying and drowning
Should ice start to melt in any real quantity in the Arctic, polar bears would migrate further north. The little ice that we have seen melt in the area appears to have been good for them do far as there numbers have gone up exponentially. From a low of 800 many decades ago, we see they have reached between 25,000 and 27,000 now. This means they are not on the endangered species list presently.
They ARE listed as a threatened species. Should the Arctic begin to melt to any degree, some groups believe this could then threaten their survival.
Do polar bears drink salt water?
No, because they can't. Some dolphins and other marine mammals can live in fresh water.
How do polar bears interact with humans?
no. they actually arent. if you type in polar bears in the google search bar there are various links that can tell you why, including wikipedia.
They are one of the few animals that go out of their way to hunt humans and kill them.
Why do polar bears have fur on the soles of its feet?
Polar bears have wide feet to spread out their weight so they don't sink into the snow.
How does a polar bears skin color help it to survive in cold winter?
White fur is harder to see against a background of white snow. And since polar bears hunt seals, it is to their advantage to be able to sneak up on seals without being seen too early.
it helps it camouflage in the snow
Do polar bears travel to get their food?
Not necessarily. During the summer, they come ashore and forge for berries and eat plants. However plant resources are diminishing and competition for them increasing. During the winter, polar bears hunt Ringed Seal on ice floes, and as both are decreasing due to global warming, one could say the polar bears will not have sufficient food over the next decades.
How does a polar bear kill a walrus?
A walrus will only kill a polar bear in defense for its life. Walruses, in water and on land, choose flight over fight when encountering a polar bear. If fight is necessary, then the walrus will attempt to kill the bear by throwing its head back and stabbing downward with its tusks. A walrus will kill a bear if those tusks injure the bear in such a way that it renders the bear's ability to hunt almost impossible, either by a stab into the paw, leg, or hindquarters, or a fatal wound to the neck or ribs.
