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.

Do Siberian tigers eat polar bears?
NO. Tigers don't live where polar bears do, so the question has no merit whatsoever.
How are polar bears different from camels?
People can ride camels and use them to carry goods, if a person tried that with a polar bear the person would probably be eaten.
Why do polar bears eat and sleep to maintain homeostasis?
Because the habitat of polar bears is a hostile freezing environment, they need to conserve every bit of energy to maintain normal body temperature. Hence, these animals doÊactivities as less as possible so as not to waste energy. After they hunt and eat, they will spend the rest of the day resting and sleeping.
What are the environmental threats to the polar bear?
- Concentration of other bears,
- Availability of food resources,
- Conditions and locations of the ice pack,
- Relative location to human populations,
- Ocean currents under the ice and how that affects the location of food populations like seals,
- Environmental changes in season lengths (which affects duration of ice pack and food availability)
How many polar bears have been saved so far?
no one knows how many have been killed. but we do know this. that 20000 polar bears are left in this whole world.
What does the energy pyramid of polar bear look like?
There is no energy pyramid on the continent, because there is no food chain on the land.
However, the Southern Ocean which surrounds the continent, has the shortest food chain on Earth, based on Antarctic Krill, properly Euphausia superba. The top of the ocean's food chain are protein-consuming whales and seals.
In the winter, when there is little to eat,a bear's heart rate slows down. Bear's don't eat or drink anything over the frostey winter. A hibernating bear can lose up to half of its body weight over the winter
What do polar bears eat in summer and winter?
Polar bears eat next to nothing during the summer time. They may try to catch a few lemmings, some birds and eat some birds eggs, but other than that they're waiting around until winter comes back again.
During the winter polar bears feast on seals, walrus and some whale.
What do female polar bears do to protect there cubs?
Well, that would be very rare since animals aren't like human beings and they kill other living beings for food and they don't go bankrupt, but hypothetically speaking if a mother bear couldn't get enough food they would probably survive on plants and bugs and whatever they can find, humans don't differ from animals as much as you may think, they gotta do what they gotta do to survive, until they seek a better life and they would probably drink dirty water, and if that certain cub was eating too much the cub would probably help the mother bear hunt.
Hope I helped!

How much blubber do polar bears have?
The average Polar Bear will carry about 3.9 inches, or 10 cm of blubber to help insulate them in their cold climate. Their fur, and hide is also designed to help protect them from the temperatures, and harsh extremes. For more details please, see sites listed below.
Will the polar bears survive after 10 years?
Polar bears are currently on the threatened species list. Reports show that if conditions do not improve, the polar bear could be mostly extinct by the year 2050. However, if we actually acknowledge this problem, the polar bears will stay around for much longer.
Who are polar bears predators?
Polar bears are typically the ultimate predator in their habitat, and nothing else preys on them. They do sometimes fight among themselves, and males may fight to the death over the right to mate. Young polar bears are preyed on by other animals, such as wolves and cougars. Humans also kill polar bears, and killer whales will catch and eat swimming polar bears if they can.
How many species of polar bear are there?
A U.S. Geological Survey of May 2008, scientists stated that the current population was estimated to be at more than 20,000 polar bears world wide. They stated that the populations were on the decline in Canada's Western Hudson Bay, and Southern Beaufort Sea. Of Canada's thirteen polar bear populations, two were decreasing, four were increasing, and the rest are listed as stable.
Currently, there are around 23,000 polar bears in the wild. In 1970, there were around 8000.
The Polar Bear population is difficult to survey. Their constant movements over ice floes, without territory boundaries and the harsh living conditions makes birth and death record maintenance an extremely difficult task.
The working estimate used by biologists is (2012) between 20,000 and 25,000 total Polar Bears.
They range across the borders of Alaska to Russia, from Canada to Greenland, and into Norway's Svalbard archipelago. It's believed that 60 percent of these Polar Bears live in Canada.
They are listed as "Vulnerable" according to the IUCN Red List. While the U.S. Fish and Wildlife Services Endangered Species List has them listed as "Threatened". Russia and Canada have also listed the Polar Bear as a "Species of Concern".
Recent studies show a 22% decline in populations in the Canada's Western Hudson Bay populations, since the early 1980s.
There are many studies completed and ongoing into the survival of this species. For more details, please see the sites listed below.
Latest estimates are between 23000-25000 animals.
Well sir, there are 3 polar bears in the world. These money loving jackweeds who give pollution to the world ultimately melt the polar ice caps. The polars bears live on da' ice caps. There was once 4 billion ca-zillion polars on this planet but now there are only 3. Make that 2, one just drowned. :)
The population is around 23000 to 25000.
The total population is around 25000.
The current population of the polar bear is around 20,000-25,000.
absolutely none (true)
25,000
there are roughly 5000 polar bears in the wild
Twenty to twenty five thousand.
Around 25000.
about 10 poler bears that have to mate
What are things that are made out of polar bears?
To be honest, there is isn't as much compared to lion, tiger, cheetah, etc. But I do know the famous one which is illegal today is polar bear carpet. They take out their inner body, clean it, and some southerners still have it in their homes today.
How large do polar bears grow?
Adult male polar bears grow to be about 770-1500 pounds and 7.9-9.8 feet long. Adult female polar bears grow to be about 330-550 pounds and 5.9-7.9 feet long. The largest polar bear ever recorded was 2,210 pounds.
Are brown bears polar bears because of the ice age?
No, polar bears are always white. However, the white coat usually yellows with age.
How many polar bears are left 2012?
There are 20,000-25,000 polar bears left in the world, acording to scientists
What is the adaptation of polar bears having white fur?
A behavioral adaptation of polar bears is that they eat only meat because there are no plants in their environment. Structural adaptations are that they can blend into the snow, and have feet that allow them to walk on snow easily.
Where do polar bears build their dens?
The female Polar Bear when pregnant will enter a den to have cubs, and stay there until they are born.
On cold days they may dig a hole, curl up and even cover their nose with a paw. On warm days, they pant, may sleep anywhere in almost any position, and may be sprawled out with unfurred foot pads waving in the air, looking more like a jellyfish than the ultimate arctic carnivore. Also, in the dark winter, they may burrow into the snow to help keep warm. In the summer, they may burrow into the earth to get away from the sun and keep cool. Sometimes they'll hide from the wind behind an ice wall or something similar
What adaptations do polar bears have living in the mountains?
I don't think that polar bears live in mountains, but I think the hollow hairs that they have contain oxygen which they heat up and use to keep themselves warm. Their seemingly white coats are for camouflage when they're hunting in the snow and the big teeth and claws used when hunting prey. They also have sticky pads on their feet to stop them slipping on ice and they have evolved to walk on all fours so that their mass is distributed evenly over the ice so that they don't fall through it.
How can people save polar bears?
all that stuff on tv is so fake... the photographer got super lucky finding a place where the ice was actually melted. there's a lot of money in the sad photography business. lol. global warming is fake, climate change is real. humans haven't destroyed the earth, there was an ice age before humans... clearly, climate changes are inevitable. the polar bears will be just fine, so smile (:
it can live up to 34 years also it can be 100 years old if it could survive that long. it depends on who old it already is
Do polar bears like each other?
Of course, yes! When they are hunting, they might have to put up a fight with the prey! Or they may fight with other polar bears (see the question, do polar bears fight other polar bears, for more information).
Where does a young polar bear live?
The Polar bear (Ursus maritimus) lives primarily on arctic coasts, islands, and adjacent sea ice of Eurasia (Norway & Russia), North America (Alaska, Canada), and Greenland (a Denmark possession).
Since the Polar bear is a marine mammal, it can be found mostly on sea ice or frozen circumpolar coastal regions. There are also Polar bears in captivity, like in the Zoo or a Sanctuary. These are usually polar bear cubs found without a mother and would have died in the wilderness unless brought into a Zoo or another safe place where it can be cared for.
Habitat: Arctic tundra and woodlands along the coasts and inland streams and lakes of Alaska and Canada in North America, also Greenland, Norway and Russia.
The Polar bears are considered to be vulnerable, not endangered (2011).
For extra points: There are no Penguins in their habitat area, and there are no Polar bears in Antarctica.
In the northern polar regions of the world, and in zoos. There are no polar bears in the southern polar regions.
They leave in Alaska, Canada or tundra.
The polar bear's natural habitat is in the Arctic, on land and on the ice. Climate change has resulted in a serious decline in polar bear habitats, so many of the bears are either dying or being forced into captivity.
Polar bears live in Alaska, Russia, Norway, Greenland, and Canada. Polar bears can also be found in zoos all over the world.
Is a polar bear stronger than a grizzly bear?
The largest bears on the planet are found on Kodiak Island, Alaska. They are Kodiak Brown Bears and they are hugh. I lived on Kodiak island and have seen many of them in the wild. They are magnificant to watch from a distance. Yes they are stronger than a grizzly. The grizzly is the inland brown bear, same species, different race.
In addition:
Kodiak bears are the larges sub-species of brown bear. They are about the same size as polar bears.
