Baby, it's cold outside! Perhaps no other animal symbolizes frozen tundra regions of Earth as do Polar Bears. They live on ice and snow, but that is not a problem. Bears have some cool ways to stay warm! An outer coat of long guard hair that sticks together when wet protects dense, thick undercoat of fur. On land, water rolls right off of guard hair Even though Polar Bears look white, their hair is really made of clear, hollow tubes filled with air. Scarring or residue on fur can cause white fur to appear to human eyes as cream color, yellow, or even pink in Arctic light. Fat acts as nutritional reserve and energy storage when food ca be find, and may provide the ability to generate heat to help insulate Polar Bears from freezing air and cold water. This fat may also help Bears float in water. It is 2 to 4 inches thick. Unlike brown Bears and black Bears, Polar Bears do not hibernate, and only pregnant females over - winter in dens. While in den, pregnant females ' activity level decreases and their metabolism slows down. During this period, she gives birth and nurses her cubs. Sometimes, when weather conditions are particularly rough, other bears may dig temporary shelters, where they spend several days at a time. The polar bear is the newest of eight bear species, and scientists believe that the polar bear evolved about 200 000 years ago from brown bear ancestors. Both Polar Bears and brown Bears are big and are the largest land carnivores. But most experts agree that Polar Bears are the longest bears, as males may measure over 10 feet when standing on their hind legs. Small bumps on the pads of Polar Bears ' large, wide paws may add traction and help Bear walk on slippery ice. Polar Bears spend their days hunting and sleeping after a good meal. For some, these meals need to last during upcoming months when Arctic ice has melt, and they are forced to spend their days on land waiting for fall cold to once again form very important ice. When not hunting, Polar Bears resting, perhaps as much as 20 hours a day. Polar Bears are great bed makers, building nest - like beds in seaweed piled up on the coast, digging deep caves of snow into bluffs, or resting in shallow snow beds and letting blowing snow cover them, making for snug day den. Polar Bears live throughout the Arctic, in areas where they can hunt seals in wide cracks in sea ice or at breathing holes. The Taxonomic name for Polar Bears is Ursus maritimus, which means sea Bear, fitting name for these champion swimmers. They have been known to swim more than 60 miles without resting in search of food, using their broad front feet for paddling and their back legs like rudders to steer.

Polar Bears are sexually dimorphic in size. Males are larger than females are. Polar Bears are covered in thick, dense coat of hair. Each hair is hollow tube that lacks pigment. When sunlight bounces off the hair shaft, it appears white in color. Wild Bears may look yellowish in summer due to oxidation of seal oil on their coat. Their fur does not repel water; Polar Bears can become hypothermic if they are immersed too long. They have 4 to 5 inches of blubber that insulates their body. They have small, round heads and long neck. Their feet are flat, large, and oarlike. They have a membrane between their toes that is up to half the length of toes. These are adaptations for swimming. Fur covers soles of paws, except for foot pads. This provides traction and warmth against ice. Black skin under fur absorbs warming ultraviolet rays of the sun. They have very long necks and small ears. Their nose, foot pads, and skin under their fur is black.

Home for polar bears is on sea ice, where they hunt seals at open leads. Polar bears are found in five nations across the Arctic: US, Canada, Russia, Greenland, and Norway. Sea ice is vast and ever - changing. Because of this, polar bear's home range can be enormousfar, larger than any other species of bear. The size of Polar Bear's range depends on two main factors: quality of sea ice and the availability of their seal prey. Unlike other large carnivores, polar bears do have territories, partly because their Sea ice habitat is always moving and seasonally changing, expanding in winter and retreating in summer. Polar bears in regions with less sea ice and fewer seals may travel further and have longer fasting periods. When a young Polar Bear grows up, it may travel more than 1 000 kilometers to set up home range apart from its mother's, although this remains scarcely a study topic, because tagging and tracking quickly maturing animals is tricky. Scientists believe that most polar bears limit travel to home ranges of a few hundred miles. However, they know of one satellite - tracked female that trekked 4 796 kilometers from Alaska's Prudhoe Bay to Greenland to Canada's Ellesmere Island and back to Greenland. Some sea ice lies over productive hunting areas, and some ice regions will melt sooner than others in the warming Arctic. Governments and scientists have designated 19 populations of Polar bears based in four different Sea ice regions in the Arctic. These populations function as distinct management units and are spread out among five countries: Canada, United States, Greenland, Russia, and Norway. Roughly 60% of Polar bears call Canada home. The following four sea ice ecoregions differ in geography, status, sea ice levels, and vulnerability to climate change. Well known for their slow, plodding gait, polar bears walk at about five to six kilometers per hour. Females with small cubs walk more slowly, about two - and - ahalf to four kilometers per hour. Polar bears are able to gallop as fast as horses over short distances but prefer to amble leisurely. Norwegian scientist Nils Oritsland shown the US that polar bears expend more than twice the energy of most other mammals when walking or running, showing higher - than - average increases in temperature and in oxygen consumption. Walking bears expend 13 times more energy than resting bears. This partly explains their preference for still - hunting, which usually involves long, patient waits for seal to surface at breathing hole in sea ice. Polar bears are List under a variety of classifications depending on international, National, and regional regulations. Internationally, they are List as vulnerable species by IUCN. In Russia, polar bears are classified as Red Data Book Species, listing that includes animals considered rare or endanger. In the US, polar bears are List as Threatened Species under the endangered Species Act. Canada considers polar bears species of special concern under the National Species at Risk Act.

The Polar Bear is a marine mammal that inhabits sea ice in the Arctic region of the Northern Hemisphere. They are the largest land carnivores on the planet, rivalled only by Kodiak brown Bears that are found in the southwestern portion of Alaska, Canada, Greenland, Norway and Russia. The Polar Bear sits at the top of the food chain in this cold, harsh environment. Their diet consists mostly of fat of Seals that share region with them. The adult male Polar Bear, known as boar, averages between 7 - 10 feet in length, and weighs between 750 - 1 550 pounds. Adult female Polar Bear,s are roughly half the size of their male counterparts. The polar bear has many different adaptations that have permitted the species to thrive and survive in the Arctic cold. The fur of polar bear is thicker than that of any other kind of bear. It even covers their feet, to provide both warmth and traction. Buoyancy and insulation is provided by a thick layer of blubber beneath fur. Polar Bears also have long necks and narrow skulls that make them quite different from other bears and help to streamline the entire body shape for swimming. The front feet of Polar Bear are flat, large and oar - like, which assists in their swimming abilities. The global population of Polar Bears is estimated to be between 22 000 - 31 000 according to IUCN, which lists them as vulnerable due to decline in area of occupancy, extent of occurrence and quality of habitat - with particular concerns about the impact of climate change.

On regional level, in Canada, Polar Bears are List as threaten in both Manitoba and Ontario under provincial Endangered Species legislation. In all cases, primary conservation concern for Polar Bears is habitat loss and reduced access to their seal prey due to climate change. Scientists predict that as the Arctic continues to warm, two - thirds of the world's Polar Bears could disappear within this century. Research also shows that hope remains for action to be taken to greatly reduce greenhouse gas emissions soon.

Appendix II since 1975. Propose for transfer To Appendix I by the United States at CoP16. Class: Mammalia Order: Carnivora Family: Ursidae Genus: Ursus Species: maritimus Polar Bears are large stocky animals with long hair, short tail, round ears, and large paws that live in the Arctic region surrounding the North Pole. Polar Bears have a whitish appearance, while their skin and nose are black in color. The Polar Bear is one of the largest terrestrial carnivores, being more than twice as large as the Siberian tiger. A Polar Bear can weigh up to 800 kg and measure up to 250 cm in total length. In order to survive in harsh Arctic conditions, Polar Bears have evolved unique features such as large furry feet and short, sharp, stocky claws, giving them good traction on ice. Polar Bears are carnivores and feed primarily on seals, especially ring seal, but also consume sea birds and their eggs, small mammals, fish, and meat of dead animals found along shore. Seals are especially important to Polar Bears ' diet because they are rich in fat and protein, which enables Polar Bears to withstand long fasting periods lasting several months. The primary Habitat of the Polar Bear is Sea Ice. Polar Bears use sea ice as platforms to capture their main prey, ring seal. Marine Mammal,s Polar Bears are excellent swimmers and are able to swim great distances between blocks or patches of ice, called Ice floes, as they hunt. During summer when most of the sea ice has melt, Polar Bears remain along the edges of the ice pack, as well as on islands and along the coast. Pregnant females construct dens in snow along the coast where they give birth to one or two cubs during winter. Typical litter consists of two cubs, but litter size may also be three or four. These cubs will remain with their mother for 2a3 years. Polar Bears range throughout the Arctic region along northern portions of the United States, Russian Federation, Norway, Greenland, and Canada. During summer, Polar Bears occur mainly along coastlines in southern portions of their range, while during winter they range widely onto Sea Ice at great distances from land. Habitat loss due to global warming restricts access to prey due to Habitat loss due to global warming. Over - harvest and commercial trade pollutants, tourism, and oil development that facilitate Bear - human conflicts and habitat loss. The primary conservation threat is loss of sea ice due to global warming, as well as decrease in quality of sea ice as it melts and refreezes. Habitat loss restricts access of Polar Bears to Seals, their main prey. Sea - ice has been reduced by 8 percent in the past 30 years alone, while summer sea - ice has been reduced by 15 - 20 percent.

Polar Bears are the largest carnivorous land mammals on Earth. They are about seven to eight feet long, measuring from nose to tip of their very short tail. Male Polar Bears are much larger than females. A large male can weigh more than 1 700 pounds, while a large female is about half that size. Bears can weigh about 50 percent more after a successful hunting season than they do at the start of the next; most of this additional weight is accumulated fat. Newborn polar bear weighs only about 1. 5 pounds. Many of the polar bear's physical adaptations help it maintain body heat and deal with its icy habitat. The bear's outer layer of fur is hollow and reflects light, giving fur a white color that helps the bear remain camouflaged. The skin under the Polar bear's fur is actually black; this black is evident only on the nose. Polar Bears also have a thick layer of fat below the surface of skin, which acts as insulation on the body to trap heat. This is especially important while swimming and during frigid Arctic winter. The bear's large size reduces the amount of surface area that's exposed to cold per unit of body mass, which generates heat. Polar bear's footpads have a kind of non - slip surface, allowing them to get traction on slippery ice. Polar Bears have strong legs and large, flattened feet with some webbing between their toes, which helps with swimming and walking on ice. Wide paws prevent sea ice from breaking by distributing polar bear's weight as it walk. Webbed feet results in making Polar bears, unlike other bear species, considered to be marine mammals along with seals, sea lions, walruses, whales, and dolphins. However, they are still Bears. The polar bear evolved one to three million years ago from the brown bear, which still ekes out marginal life along the northern shore of the Arctic oceans. Unlike the massive Polar bear, which can grow huge on a diet of abundant seals, its ancestor in the Arctic is small, has very lower reproductive rates, and eagerly eats almost anything that exists in its environment. Polar Bears have evolved something else that is different from their ancestor: most Polar Bears do den, but all brown Bears do. When grizzly bear food is covered in snow during winter, this species must die because there is nothing to eat. In contrast, most Polar Bears have access to their food of choice all winter long, so there is no need for them to den. An exception to this is pregnant adult females. Pregnant female Polar bears must den so that their tiny newborn cubs are born in a warm protected environment; dens can be 38 degrees Fahrenheit warmer than the outside temperature. Cubs would otherwise freeze to death in frigid temperatures of the far North. Most Polar Bears occur north of the Arctic Circle to the North Pole.


Interesting Polar Bear Facts

Around the age of four or five, female Polar Bears can start having babies. They usually only have two cubs and they have these babies in cave they ve dug in large snow drift. They stay there over winter and come out in spring with babies. Babies are much smaller than human babies when they are 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. Male Polar Bears may grow 10 feet tall and weigh over 1400 pounds. Females reach seven feet and weigh 650 pounds. In the wild, Polar Bears live up to age 25. Despite what we think, Polar Bear's fur is not white. Each hair is clear hollow tube. Polar Bears look white because each hollow hair reflects light. On sunny days, it traps the sun's infrared heat and keeps Bear warm at 98 degrees F. Polar Bear fur is oily and water repellent. Hairs don't mat when wet, allowing Polar Bears to easily shake free of water and any ice that may form after swimming. Underneath the fur, Polar Bear's skin is actually black - black skin that soaks up the sun's heat and helps them stay warm. Polar Bears also have a 4 inch layer of fat underneath their skin. This prevents them from losing any of their heat. In fact, if you look at Polar Bear with an infared camera, they are pretty close to invisible. Polar Bears have wide front paws with slight web toes that help them swim. They paddle with their front feet and steer with their hind feet. Paw pads with rough surfaces help prevent Polar Bears from slipping up on ice. Polar Bears have been known to swim 100 miles at stretch. Polar Bears primarily eat seals. They often rest silently at sealas breathing hole in ice, waiting for seal in water to surface. Once the seal come up, bear will spring and sink its jagged teeth into the sealas head. They have a special liver that allows them to process all of the seal fat they eat - seals store a lot of vitamins in their blubber, which allows them to survive and grow quickly. The Polar bear's liver contains 10 times more vitamins than any other animal on Earth - their liver has evolved to allow them to process and eat all of the seal blubber they need to stay alive. Sometimes Polar Bear stalks its prey. It may see a seal lying near its breathing hole and slowly move toward it, then charge it, biting its head or grabbing it with its massive claws. Polar Bears may also hunt by swimming beneath ice. Humans are Polar Bears only predator.S Baby Polar Bears often starve. In fact, 70 percent do not live to their third birthday.
