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.

What group does the polar bear belong to?
Polar Bears belong to the Bearfamily. Their scientific name is ursus maritmus which is Latin for maritime bear and refers to their natural habitat. They are native to the Arctic Circle -Arctic Ocean and its surrounding seas and land masses
Do polar bears live in tropical rainforest?
yes , because their are whales i mean i dont know you tell me i hate this website
Depending on the sex of the beaver. Males beavers are called "Mr. Beaver" Female beavers depending on relationship status are known as "Ms. Beaver or Mrs. Beaver" A young female beaver is often refered to as "Miss Beaver"
How do animals of polar regions survive the cold?
Because the animals such as, Polar Bears, have adapted to the weather over a long period of time. So every animal in cold regions are born with a thick heavy furr coat to survive the harsh cold weather.
What does the polar bear's Latin name Ursus maritimus mean?
The Name "Ursus maritimus" is the scientific name for the Polar Bear
The full classification is as follows: # Domain: Eukarya # Kingdom: Animalia # Phylum: Chardata # Class: Mammalia # Order: Carnivora # Family: Ursidae # Genus: Ursus # Species Ursus maritimus The name "Ursus maritimus" is Latin for maritime bear, and was first used by Phipps, because of the bears native ocean/shore habitat. For more details see sites listed below. The scientific name for the Sun Bear is "Helarctos malayanus".
People, Killer whales, Walreses, and other polar bears
A polar bear's enemies are humans and other polar bears. But a polar bear's worst enemy is a killer whale.
Polar bears enemy is mostly human and other polar bears!
Climate change/global warming and the melting ice sheet, starvation, humans, summer in the arctic (since this is a time where they are not going to be eating much), dehydration, etc.
Humans
Humans
the ememies of polar bears are, Male polar bears, black &
white killer whales, arctic foxes, global warming and humans
Good names for male polar bear?
A male polar bear is called a polar bear. Their scientific name is Ursus maritimus. The male polar bear can get as large as 450 lbs.
Male bears are called boars, females sows. The male polar bear can weigh as much as 1400 pounds or more.
Is the polar bear the most powerful animal on earth?
No, Polar bears are the eighth deadliest animal in the world. this may surprise you but the deadliest animal in the world that kills the most people - mosquitoes.
Here's the list (top Ten)
1. Mosquito
2. Asian Cobra
3. Australian Box Jellyfish
4. Great White Shark
5. African Lion
6. Australian Saltwater Crocodile
7. Elephant
8. polar Bear
9. Cape Buffalo
10. Poison Dart Frog
Do polar bears eat animal carcasses?
They have a strong nose so sometimes instead of hunting for food they take the easy path by eating what humans leave. Since garbage as food is unnatural, humans need to take a step and keep everything sealed so bears won't be able to reach it.
Is a polar bear's skin waterproof?
The skin helps the bear to protect itself when it is attacking or being attack by some animal or some people.
What are some solutions to protect the drowning polar bears?
The first would be to understand that polar bears are not drowning. There has been an increase in the polar bear population, and growth of the polar ice cap. The size of the ice caps change from time to time. While I have seen ads that seek to convince you that the North Pole has turned into the tropics, it is just not so. Please take the time to do some checking of the facts on your own.
Why do the polar bear's adaptations make it harder for it to survive in different climates?
It is hard for them to lose what they were naturally given for ice regions.
What is the body part that assists polar bear in swimming and walking?
* it has black skin which absorbs heat
* the big paws have a large surface area so they are warmer and can walk across the snow
* it has a layer of fat that works as insulation
Why are polar bears being endangered?
In brief:
Polar bears are in danger of extinction in the future if global warming is not stopped. Their habitat, the Arctic sea ice, is melting more and more every year, making it difficult for the bears to store enough food (as fat) to last them through the summers, which are lengthening. Furthermore, weak female bears produce fewer cubs.
More detail:
The polar bears' current risk of extinction:
The polar bear species' existence is threatened, but, contrary to a widespread misunderstanding, they are not listed on the main Endangered Species Lists with a status of Endangered at present. They are listed as Threatened in the US Fish and Wildlife Services Endangered Species List, and the International Union for the Conservation of Nature (IUCN) Red List has them listed in 2011 with a status of Vulnerable (a subcategory of the IUCN Threatened status), along with a population trend of Decreasing.There is common confusion about the different lists' status categories and their meanings.
In the IUCN Red List, Vulnerable is a subcategory of Threatened. There are three main status groups on the IUCN Red List to qualify the level of peril: Extinct, Threatened, and At Lower Risk. The IUCN Threatened status is subcategorized into three additional status levels: Critically Endangered, Endangered, and Vulnerable. So, as on the US list, polar bears are considered Threatened on the international IUCN Red List, and further qualified there with the Threatened subcategory of Vulnerable.
The fact that polar bears are not yet at the status of Endangered may be due, in part, to the foresight of the five nations that agreed to make polar bear conservation a priority and protected them by signing the International Agreement on the Conservation of Polar Bears in 1973. The five nations were: Canada, Denmark, Norway, USSR, and USA, ranges of polar bears in the wild. See the related links below for more information about the statuses and listings.
Why are they Threatened?
The polar bear population has suffered from various forms of hunting including, but not limited to, unregulated sport hunting from aircraft and from icebreakers, which were common hunting practices in the past. There was also unregulated hunting of polar bears in their known denning areas during the birthing season. These practices are now prohibited or regulated in the nations that host the polar bears' ranges and that agreed to put conservation measures in place. But the polar bear is a slow reproducer and the populations are still listed as decreasing overall in IUCN's Red List, despite those decades-long regulations against various forms of hunting.
Plus, the very nature of the polar bear makes it difficult to observe, protect and study. They do not behave as many other large carnivores do, who claim large territorial hunting areas that they then mark and patrol. Polar bears are a free rangingspecies and they use different migrating range patterns from hunting ice floes, to the shore line, and on inland. This makes the preservation of their habitat especially critical and difficult. They move over great distances following the ice floes for access to their main food sources and denning areas. This migration varies and is controlled, impacted and changed to some degree by the weather, breeding, and birthing seasons. Their habitat loss has been determined to be in large part due to climate change and melting.
Pollution has also significantly impacted their ecosystem and has resulted in species population decreases. Pollution has a huge impact on them due to their specialized diet. They are the top predator of their region, so they are exposed to pollution and toxins encountered through their food sources.
Polar bears are a specialized species adapted to a specific environment, therefore, any environmental change has a dramatic effect on the populations as a whole. Many studies are underway to determine what impacts the major shifts in the temperatures have had or may have on this species and their habitat and food sources. It is already known that females will not give birth if they are under normal weights. If they do give birth while malnourished, often the cub is undernourished at birth, too, and the mother continues to have trouble providing the cub with the proper amounts or quality of milk to allow the cub to survive and have normal growth. The normal survival rates for cubs is on average low, but with any additional stress on the mother or cub, those rates drastically decline further. Her ability to adequately hunt and feed the cubs depends on her body being nourished and in peak condition.
Many scientists who study their environment and needs are uncertain as to what type of changes the polar bears' habitat may continue to experience, but they are agreed that even minor changes in the habitat will have far reaching negative effects on the polar bears' populations, food sources, birthing and survival rates, and on the stability of the ice floes which are critical for hunting and feeding. The polar bear is a threatened species, perhaps mainly because of melting and shrinking pack ice caused by warming of the earth's climate.

The polar bear is not an endangered species. Listed as "Vulnerable" by the IUCN.
Answer 2:
In May 2008 the U.S listed the polar bear as a threatened species under the Endangered Species Act.
Polar bears depend on sea ice for hunting and breeding. Summer ice loss in the Arctic now equals an area the size of Alaska, Texas, and the state of Washington combined.
The video link below shows the white summer ice getting smaller and smaller every year from 1978 to 2008.
In 2009 the IUCN, the International Union for Conservation of Nature, at a meeting of its Polar Bear Specialist Group stated:
- The greatest challenge to conservation of polar bears is ecological change in the Arctic resulting from climatic warming.
- Unabated global warming will ultimately threaten polar bears everywhere.
- Declines in the extent of the sea ice have accelerated since the last meeting of the group in 2005, with unprecedented sea ice retreats in 2007 and 2008.
- Where habitats are stable, polar bears are a renewable resource. We support the right of aboriginal groups to harvest polar bears within sustainable limits.
- One of 19 sub-populations of polar bear is currently increasing, 3 are stable and 8 are declining. For the remaining 7 sub-populations available data were insufficient to provide an assessment of current trend.
- The total number of polar bears is still thought to be between 20,000 and 25,000.
- Interpretations by scientists and local hunters disagree regarding population status.
- We are optimistic that humans can mitigate the effects of global warming and other threats to polar bears, and ensure that they remain a part of the Arctic ecosystem in perpetuity.
The polar bear is in danger because global warming is causing the ice caps to melt and the polar bears live on the sea ice so if their's no ice the polar bears will be homeless and because people hunt them down for their winter coats since their soft and thick. hope this helps. And also if they don't have any ice to stand on they will drown because they will have to live in the water. And the seals and whales and other sea animals have a better advantage of get it. So then the polar bear will become enxtinct
The ice caps have returned to previous high levels, because their has been no warming for 18 years. The polar bear has a population of nearly 25,000, and they are currently under no threat of extinction. The global warming alarmists predicted the ice caps would be gone by 2013. In fact, both are growing in coverage, so don't believe all you hear from them.
The Polar Bear is not listed as "endangered" according to the US Fish and Wildlife Services Endangered Species List, or the US FWS. The Polar Bear is listed as "threatened" by the US FWS, and as "vulnerable" with a population posted as "decreasing" by the International Union of Conservation for Nature, or the IUCN Red List. The Polar Bear has been listed due to the current loss of habitat, contact with humans, and the projected changes that climate change is forecast to have on their environment. With the decreasing numbers of prey and the limited access to their prey, the Polar Bears will not give birth as often or to as many cubs. When they do have cubs, birth weights will be lower, decreasing the chances of survival for the cub. Plus the Polar Bear is a specialized species, and it depends on it's adaptions to survive in a harsh cold climate. Those adaptions will work against the Polar Bear in a quickly changing environment. For more details, please see the sites listed below.
As you know, polar bears live on Icebergs. And again, it's GLOBAL WARMING, which makes the Earth warmer. Therefore, the icebergs will melt slowly. The polar bears will end up "homeless". And most probably die in the water.
Polar bears habitat is governed by ice caps and the ecosystem it holds. Global warming is effecting the ecosystem very negatively, which also puts Polar bears at a bigger risk. Their strength has already been started reducing. Another view: the current warming trend has parts of the Arctic melting slowly. At the current rate we only have a few thousand years of ice left. Global warming is not considered a current threat. Over hunting could be. They are not considered endangered so hunting of polar bears is still legal and could stop the current population growth of these bears.
They are not anywhere near endangered and no responsible group claims this. There numbers were down to 5000 in the 60's and now number around 25,000.
Selective hunting is allowed because of their healthy population.
Some groups claim that if global warming increases that maybe the polar bear could become endangered. Most do so for monetary purposes.
That cute little polar bear you see sitting all alone on a chuck of ice stranded is awesome for getting a few dollars not of people that do not understand the issues.
Polar bears are also referred to as sea bears because they love to swim and can do so for long periods f time. They can not get stranded on a glacier.
Habitat destruction as a result of global warming, and pollution. The polar icecaps melting causes habitat destruction, and pollution limits food sources. Therefor, polar bears are being forced farther and farther south, where they are not considered welcome by humans.
Mostly by globel warming.
-from when one of us smoke
Polar bears, with a current population of 25000, are listed as "Vulnerable", not endangered.
The polar bear currently is not considered an endangered species.
The polar bear actually is not an endangered species, with a population of around 23000 or more.
The polar bear is listed as threatened, or vulnerable. Since 1975, the population has grown from 7500 to over 22,000 today.
They're not an endagered species. Listed as "Threatened" by the IUCN, or "Vulnerable". The population in 1970 was around 7500. Today, there are nearly 25,000, a surprising increase in numbers.
They probably are endangered because if Global Warming. The ice melts and that means their habitat melts. Also if they are on an iceberg, it might drift away to warmer waters and melt, stranding the polar bear in the middle if the ocean.
cos' 0f global warming the ice is melting which is causing an effect on most of the animals there.
Polar Bears are very vulnerable to climate change and human hunting. Due to their sheer size, they have no natural predators except themselves. Large males have been known to kill off younger/smaller bears to cut out on competition. Man has been hunting these giant carnivores for centuries for its skin and fur. As of now, approximately 20000 to 25000 animals exist in the Arctic wilderness. Their numbers are steadily declining due to habitat loss and hunting. Oil and Gas exploration in the Arctic too is a significant cause for the decline in Polar Bear numbers. Due to human activity and global warming, the ice caps are melting. So, the effective land that the bears have for hunting is coming down. Pollution too is killing off prey species. So, everything put together is endangering the species.
polar bears are endangered because people are killing them for fur, and the Arctic ice is melting due to global warming, leaving them without food or shelter.

they are endangered because of us we started global warming which will probably kill everything, along with polar bears!
Global warming
Global warming
They feed on the ice surface by waiting above seal breath holes, with declining ice surfaces the loss of habitat makes hunting seals more challenging and many are dying of starvation and even turning to eating their own in desperation.
There not they have increased from 5,000 in the 1970's to 25,000 today. They are great swimmers. They can swim 100 miles at 4-6 mph, nick-name water bear.
The polar bear, Thalarctos Maritimus, is currently not classified as endangered, but threatened or vulnerable. Population of 25000 worldwide.
people are killing them and selling there body parts
The polar bear is listed as Vulnerable, which means it has the potential to become an endangered species if certain factors cause the population to drop to levels which the animal cannot sustain itself.
But as for now, polar bears are not considerd an endangered species.
The popular notion is this animal is in trouble because of global warming, but again, the jury is still out on that theory.
They are not endangered by any list.
because they can not find food so they die from hunger
not sure....

An amazing set of answers I got for you while researching this. First, polar bears are not endangered, but listed as threatened. But, the World Wildlife fund says the population is increasing. I will ask you to go to the IUCN Redlist, maybe they can give you the info. I keep coming up with conflicting evidence.
There endangered because the polar ice caps are meltingis the common belief.
The reality is that the arctic is not melting away and these creatures are not endangered. Reality over politics is that their numbers have grown to over 20,000.
Last year the Arctic saw record ice growth.
It currently is not endangered! Please check the IUCN Redlist for status on this species. Additional Info: The IUCN Red List currently lists the Polar Bear, with a status of "Vulnerable", with the populations "decreasing". While the U.S. Fish and Wildlife Service Endangered Species List, also lists the Polar Bear, with a status of "Threatened". One of the reason given for the listing of "threatened" was decreasing population in some areas. This was linked with the lack of prey, and less summer ice, creating a longer fasting period for the Polar Bears. Which stresses the bears nutritionally, effecting their ability bare, and feed young during the following season.
Polar bears are endangered because global warming is melting the ice on which they live on.
They are not endangered. They are growing in population. We know that there are between 20,000 and 25,000 bears in the Arctic today (way up from 800). Wolves are being considered as a potential animal to be taken off the list at 8000.
This does not mean that the senseless hunting of these creatures should continue.
Do polar bears give birth to their cubs?
Around the age of four or five the female polar bear can start having babies. They usually only have two cubs and they have these babies in a cave they've dug in a large snow drift. They stay there over winter and come out in spring with the babies.
The babies are much smaller than human babies when they're born. They are the size of a rat and weigh little more than a pound. They can grow to full man size in a year if they have lots of food.
This is the source that I found it from. http://www.kidzone.ws/sg/polarbear/polar_bear.htm
Kodiak bears or coastal brown bears are the biggest bear species in the world, and can weigh up to 1500 pounds or even 1800 pounds! When they stand up, they are about 3 meters tall! Polar bears weigh from 1190 pounds to 1475 pounds, and eventually over 1700 pounds! The polar bear is longer than a brown bear by about 2 ft and taller when standing up by 7 inches to 1 ft. The brown bear is about 3-6 inches taller at the shoulder and heavier by 10 to 40 pounds. Grizzly bears or amur brown bears are usually 800 pounds to 900 pounds and 8 ft tall, but can weigh over 1000 pounds and be more than 9 ft tall. Black bears, especially ones found in the east coast and north, can get over 600 pounds and the largest ones are over 800 pounds! They can be as tall as a male basketball player when standing up on hind legs!
Could polar bears live in the Antarctic?
No: polar bears live in the northern Arctic regions, not in the south at the Antarctic. There are no polar bears in Antarctica.
No. They are only found in the Arctic.
No
What animal can kill or eat polar bears?
Polar bears are sometimes injured, and could die from the wounds, when attacking a walrus herd in the hope of isolating a weak adult or young animal . When the pack ice melts in summer, polar bears have to live off fat accumulated by eating seals on the frozen winter pack ice during winter. Sometimes, a polar bear, who hasn't accumulated enough body fat, may starve to death before the pack ice reforms. In desperate times, a hungry polar bear may resort to scavenging off dead whale/seal carcases washed up on shore, or even entering human habitations and going through the bins.
How did or will the extinction of the polar bear affect humans?
They will eat them if they can catch them.
One man commited suicide by jumping into the bear pit at Stanley park zoo (Vancouver, Canada). They gave up on trying to recover his body. They tried hitting the bears with high pressure water hoses - but polar bears like that sort of thing.
What do polar bears have to compete for against others in the same species?
They have a thick fur coat of fluffy white hairs to keep the cold out of their blood!?
Well they have thick, white fur to help it keep warm and camouflage itself.
It has wide paws so they don't sink through the snow.
They Have pads on their feet.
Sharp claws and teeth to kill and eat its pray.

polar bears survive because they live in in the Arctic and that is a very cold place to live
Polar bears are adapted to live in very cold weather conditions. They have very thick fur that protects them from the cold. They also eat fish and other plants.
What was the polar bear population in 2005?
According to the World Wildlife Fund, there were approximately between 20,000 to 25,000 polar bears in 2015.
According to the IUCN organisation, there were approximately 26,000 polar bears in 2015.
How does a polar bears their fur keep them 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.
As well as this, polar bears have a thick layer of blubber, or insulating fat, which can be up to 11 cm thick. Their fur is also waterproof, so it helps keep the bears warmer when they are in water.
With their high cold temperatures at the North Pole.
