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.

Did polar bears come from grizzly bears?
Polar bears evolved from brown bears, but not necessarily the grizzly brown bear.
Bears, in the taxonomic family of Ursidae, split off from other Carnivorans about 38 million years ago. Then the Ursinae subfamily originated around 4.2 million years ago. According to both fossil and DNA evidence, the polar bear split from the grouping of the brown bear, Ursus arctos, roughly 200,000 years ago. This is thought to have happened due to their isolation during a period of glaciation in the Pleistocene period.
What is the area of Polar Bear Pass National Wildlife Area?
The area of Polar Bear Pass National Wildlife Area is 2,675 square kilometers.
What is the range for a polar bear?
The polar bear actually lives in the Arctic, which includes Russia, Canada, Alaska, Norway, etc
Do polar bear have webbed feet?
They dont have webbed feet its normal feet
No they have paws and claws
Are polar bears good swimmers?
The scientific name of the polar bear is Ursus Maritimusor "seagoing bear" reflecting the fact that it is often seen at sea up to 320 km from land and swimming at a speed of 5.5 km/hr, (a bit of math shows the bear has been swimming for 60 hours to get to that point and has 60 hours to get back)
The polar bear's body fat provides buoyancy, and its large paws useful for walking on snow are equally adept at moving the bear in water.
Does a polar bear show parental care?
the one in the Pittsburgh zoo
yes,
polar bears are very protective of their young.
If you like someone should you tell them?
yes you should tell someone if you like them the hardest thing is going thru life and wondering what if, what if, what if and then if it never works out then you will never be left wondering what would of happened if you would of told! hope this helps. JUST DO IT!!!!
Why don't polar bears mate for life?
Polar bears are solitary creatures. They don't mix well together, and will often fight each other if they meet, especially with a boar bear meeting a sow and her cubs. Boar bears often will kill cubs, even if they're not hungry enough to eat them.
What are the statistics of a polar bear?
Here is a good interview with Dr. Nick Lunn of the Canadian Wildlife Service - one of a handful of scientists focusing their efforts, knowledge, and talent on studying the polar bear.
"The population in the Western Hudson Bay region has declined 22% in 17 years, to less than 1000 bears."
"Of the thirteen populations of polar bear in the world, only two are considered as thriving, as many as five may currently be stable, and the rest are either threatened, in decline, or there is simply not enough data to make a reliable assessment."
Some people will argue that polar bear populations are increasing, but this is simply a lack of understanding.
"It isn't hard to find media reports stating that polar bear populations are at historic highs - up to 25,000 now from a low of 5,000 or so in the 50's or 60's. This gets a chuckle from Nick. Look in any of those reports for the source of their conjecture. The fact is nobody was even paying attention to polar bear numbers in the 50's or 60's, much less conducting a scientifically sound census survey. So where do they come up with those numbers? Hmm… Good question.
In the 50's and 60's polar bear were being shot, killed, hunted down wholesale. It has only been within the past couple of decades that scientists, government leaders, and wildlife managers have realized that it might be prudent to put some limits on the carnage to assess what it is we have in the way of polar bears and to begin serious, ongoing scientific study of them.
What happens when uncontrolled hunting is stopped? Gosh, it seems there may have been some recovery in polar bear populations due to the alleviated stress from hunting. (Incidentally, 500 bears are still harvested every year in Canada.)
When you hear anyone authoritatively pronouncing that polar bear numbers have recovered from 5000 to 25,000 just know that they're simply guessing. Right off the bat a reason to question the veracity of their argument. (And when the Wall Street journal says anything about environmental policy, assume they likely don't know a whit about what they're talking about.) "
How long can a polar bear hold its breath?
A polar bear can only hold its breath underwater for a little more than a minute.
What is the average height of the polar bears legs when standing on all fours?
The polar bear is the largest carnivore on the earth. They can measure between 2.4 to 3 meters in length (7.9 to 9.8 feet). Females are comparatively smaller and and measure 1.8 to 2.4 meters (5.9 to 7.9 feet) in length.
Standing on all four feet, their height at shoulder is around 130 to 160 cms (4 to 5.5 feet) and while standing they can be as much as 10 feet or more in height.
How many predators does a polar bear have?
There is only one species that hunts polar bears, and that is man.
When they meet who wins the fight between a polar bear and a grizzly bear?
a polar bear will most likely win in a fight against a grizzly bear
Why is the polar bear called the white hunter?
This huge white hunter of the Arctic follows the migrating seals as far south that is why its called the White Hunter.
How do you write the introduction in an informal report?
You must keep in mind that an introduction is only an overview that covers what your going to talk about in the following paragraphs =]] .....
How does the polar bear's fur keep it warm?
In addition to having a large amount of hair, Polar bears have hollow fur. this allows more heat to be trapped in the fur as air is a good insulator
they have two layers of fur (just a guess)
there fur is like a whale it has blubber and its thick
Polar bears have very thick fur so that helps. The fur holds air and serves as insulation that holds in body heat. It is like a coat on a human. They also have black skin underneath that white fur and the sun glares on the black skin, helping them to stay warm.
because polar bear fur is hollow, and air is a good conductor.
The thick coat of fur traps air that is a poor condutor of heat which slow down the heat loss from escaping quietly from the grizzly bear's body to the cold surroundings, thus keeping the grizzly bear warm.
The polar bears coat is about 2.5 to 5cm thick. So they must be pretty warm.
Polar bears have transparent fur over black skin. Reflection of the sunlight from the densely packed transparent hairs makes polar bears seem to be white. The bears' black skin absorbs heat from the sun. The transparent fur is made up of hollow hairs called guard hairs. These air-filled guard hairs help transmit heat from the sunlight to the polar bear's black skin as a solar heat collector. In turn, the reflection stops the heat being lost from their black skin.

Why do polar bears sway in captivity and how can you treat it?
That means they are bored and don't have enough room.
How do you stop yourself from being so high maintenance?
Stop being materialistic and start being more grateful for life and the people you have as friends and family.
its a judgment not a collection agency? all i can say is check on it, also check what your state allows per-year in interest charges. you know three years ago you should have paid atlease 20.00 a month just to show your good fate, believe me in the long run the 20.00 a month would have been seen as an effort on your part.
If I would suddenly be a polar bear the first thing I would probably do is wonder how I turned into a polar bear. If that costs me too much energy or I don't like thinking about difficult human things with my polar bear brain I would walk somewhere where it's colder in the hope to find other polar bears. And of course I would go fishing and hunting. The most important thing I would do: go to the room of my little brother, hide under his bed and scare him in the middle of the night. Nobody would believe him of course - I mean why should a polar bear be under a child's bed in the middle of the night - It's the perfect joke.
