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.

Does a polar bear weigh more then a horse?
No.
It's possible. A large male can be nearly 1500 pounds, and there is a disputed record of a male polar bear of 2100 pounds.
Why do polar bears get called polar bears?
Polar bears live at the polar region (the Arctic) of the world, and are only found there, unlike other bears. This is why they're called "polar bears."
The polar bear is called a polar bear because it is a bear, and lives in the area of North pole in the Arctic.
So Don't Be Fooled When You Think That Polar Bears Eat Penguins. Because They Live In Diffrent Places.
I am pretty sure they eat fish, or berries, but not squid.
The difference between polar bears and Eskimos?
For a start, the koalas is not a bear, but the polar bear is. The word "bear" is not even part of the koala's name. Differences include:
- Koalas are marsupials, giving birth to undeveloped young which complete their development in the female koala's pouch. Polar bears give birth to live young which are fully developed.
- Baby koalas are called joeys, while baby polar bears are called cubs.
- Koalas are endemic to Australia alone. Polar bears are found in Arctic regions.
- Koalas are herbivorous, feeding only on eucalyptus leaves, flowers and bark. Polar bears are carnivorous, i.e. meat-eaters, feeding on live prey.
- Baby koalas drink mother's milk during their first 6-7 months of life. After 30 weeks, the mother produces a substance called pap. This substance is actually a specialised form of the mother's droppings which, having passed through her digestive system, give the joey the enzymes it needs to be able to start digesting the tough gum leaves, making an easier transition for the baby koala to start eating eucalyptus leaves. Polar bears make a simpler transition from mothers' milk to meat, and no such preparation is required.
- Koalas are essentially grey in colour, while polar bears are white.
- Koalas are arboreal, or tree-dwelling, while polar bears live on the ground.
- Koalas are much smaller than polar bears.
- Two of the koala's digits on their forelimbs act as opposable thumbs, enabling koalas to reach out and grasp the leaves they want. Polar bears do not have any such feature or capability with their paws.
What animal is similar to the polar bear?
Grizzly bears. They share some habitat areas. Eat alot of the same things, and even cross-breed occasionally. Grizzlies can also swim, but they can't tolerate the frigid waters as well. Their closer habitat companions, seals, are also mammals that share habitat areas. Both hunt for fish, but the seal is also a prey animal for the Polar bear.
Grizzlies and Polar Bears interbreed. That makes them pretty closely related. See link

Why are polar regions cooler than equatorial regions?
The polar regions get the least amount of warming rays from the Sun.
How is a polar bear born with an egg or from a mom?
Polar Bears are mammals, and give live birth to usually one or two cubs.
Impossible to say. Polar bears live all across the Arctic Circle, in several countries. They are superbly camouflaged and don't gather in herds. Methods of counting them are very general and scientists hope they are reasonably accurate. But we can't tell how many are dying.
Are polar bears at risk of being endangered?
The polar bear is not listed with a status of endangered now, this may be due in part to the foresight of the five nations that agreed to make the polar bear a priority, and protect them by signing the International Agreement on the Conservation of Polar Bears. They are currently listed as "Threatened" by the US Fish and Wildlife Services, Endangered Species List, and the IUCN Red List, has them listed with a status of "Vulnerable" and the "population trend of decreasing".
Yes, the Polar Bears are an indangered spaecies
The polar bear is not yet an endangered species. However, it was recently considered to be a threatened species, meaning it is at risk for becomming endangered.
No, they are listed as vulnerable.
The polar bear is listed as vulnerable by the IUCN.
The polar bear is currently listed as "Vulnerable", with a population of nearly 25000.
Yes. The Arctic Polar Ice Cap is melting, possibly due to Global Warming, and this is the Polar Bears' natural habitat. They can not compete in open water or on dry land, as they tend to feed on seals that are below the ice, breaking through the ice to capture them.

No, no Government or science group claims this. Political groups do, but they are ignoring the growing numbers.
No they are not, but are considered threatened. See IUCN Redlist.
yes they are indangerd
How do polar bears walk on such thin ice when they weigh so much?
They break through thin ice as they have amazing power in there shoulders, which when pushed against the ice breaks.
Why do polar bears live in the cold?
because they have fur that will not fit in the savanna, rainforest's, or other places but the arctic.
Also that is where they evolved so over the evolution process their bodies adapted to the harsh conditions of the Arctic
Polar Bears live in the arctic cause they need a cold place to herd, breed, and den.
How much does it cost to adopt a polar bear?
If you wish to "adopt" a baby polar bear go to your local zoo or the national zoo and make a donation to the zoo. Otherwise you can not have or adopt a baby polar bear. They are one of largest meanest bears and do not stay a baby for very long. Buy a stuffed one from Build A Bear.
polar bears are diurnal, because they sleep and rest at night and stay awake in the day to catch there prey or look after there cubs but they do rest at night just like our humans....,
Why do polar bears have such thick coats?
They live in the Arctic, if you haven't noticed yet, it is very cold up there and like all other living organisms if their body temperature dips below a certain level their fluids freeze and they die,
If polar bears were extincthow will it effect humans?
Well, polar bears eat seals. If all polar bears got killed and disappeared, then the seal population would rapidly increase, and then all the food for the seals would decrease because there's so many seals. So to sum up, having polar bears killed off would greatly decrease seals food, then the seals food would disappear, and then the seals would starve to death themselves. It's kind of scary isn't it...
An example of Mutualism on the Polar Ice Caps?
an example of this would be like... the relationship between a carribou and the vegetation. The carribou eats the vegetation, and the carribou's waste provides fertilizer for the plants.
What do polar bears eat and how do they live on the land?
Polar Bears eat meat. They eat seals, and penguins, and walruses, and basically anything they can get. Except for maybe leopard seals because those things are crazy but I still bet a polar bear could one on. They live on land because they don't have gills or wings. Where else would they live? Polar Bears have black skin to attract heat from the sun and tons of fur to keep them warm. They can swim, not the greatest but well enough to go after penguins or seals. Polar Bears normally live in caves but they also have crazy sharp claws and can dig little homes for them selves and their babies.
Why do polar bears have long necks?
A female's neck is smaller than her head, which is the same as people. A male's have such strong and big necks, that their neck is larger than their head.
Imagine that your finger is a polar bear's head and neck. The tip of your finger is the bear's head.
Will polars bears die out if antarctica melts?
Unless scientists have validated that if and when Antarctica melts, the rise in the ocean levels will flood all of the earth, then no all of the animals will not die. There are many species that naturally will move to higher ground as a matter of their natural routine, others will adapt and instinct may drive them to higher ground.
Animals also include fish, so unless the ice contains harmful toxins that can kill fish, fish and water mammals will survive.
Are the polar bear populations decreasing?
Yes. The Arctic sea ice, their habitat, the only place they can hunt seals, is decreasing every year from global warming. Bears are weakened from hunger and female bears are having fewer cubs.
What is the minimum temperature needed by plants to survive?
Depends on the plant; some plants easily live in sub-zero temperatures, others need temperatures to be quite high (e.g. over 70 F).
How did polar bears become extinct?
They are not extinct yet, but there is a strong possibility that they will be, if we don't stop global warming. Their existence is threatened because their habitat, Arctic sea ice, is shrinking because of global warming.
polar bears love to have orgasms,it reduses there natural lifestyle.
