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 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.
They like salmon, human trash like food scraps and most of all they liek to eat humans called CYNTHIA!!!!!!!
People who live or lived in polar lands?
Idiots? Just kidding. Although I can't imagine wanting to live at either pole as I am not a fan of being freezing cold most of the time.
Actually, most of the people "living" at the poles are researchers who do not live there full time. Neither pole is a country of itself. Both have regions that are claimed by different countries but there are no permanent settlements there that I know of.
How does the plants in the polar regions adapt?
Animals grow thicker fur and/or change how they act and react. Learn to use objects and bodyparts to their advantage. Plants will grow harder stems to withstand hard-packed snow on top of them. They will also need to know how to grow fruits tat will last longer in cold or freezing weather.
No creatures have polar bears as part of their diet, but killer whales rarely eat small cubs swimming in the water. Myths about adult male polar bears killing cubs are false. It is true that adult polar bears sometimes eat cubs, but these cubs are ones that have already died, perhaps of disease. mother polar bears with cubs will defend their cubs against adult males, but that is because the mother will try to avoid any potentially risky situation. no, only people

Do polar bears spend most of their time on land?
Polar bears eat seals, and seals are found in the sea.
Are polar bears going to extinct this year?
If global warming continues, and there are no signs yet of it even even slowing, then there is a strong possibility that polar bears will become extinct. If their habitat, the sea ice, disappears, they will be forced onto land to compete with other bears for food. They may begin mating with land bears and the polar bear may disappear.
Polar bears are not close to extinction now, there are still probably several thousands of them left, though it's difficult to count their numbers with any accuracy.
However, polar bears are in danger, because their habitat, the Arctic sea ice, is shrinking because of global warming. Bears feed mostly on seals which they catch on the sea ice, and rely on vast amounts of seal fat eaten from late April till mid-July to last them through the food-free summers.
Because of global warming, the sea ice re-forms later each year, so polar bears have to wait longer before they can start to hunt again.
Weakened female bears have fewer cubs, and this is the problem.
Polar bear that has a blue tongue?
A Polar Bear has black skin covering their entire body. It is thought to help them absorb the heat from the sun, during the season when that part of the world has full sun. So, they would have black lips. But if the lighting was just right they may appear to be dark purple. For more details, please see sites listed below.
Why don't polar bears live in New York?
Koalas are indigenous to Australia and live in tropical to temperate eucalypt forest and woodlands and can be found along the eastern and south-eastern coastal regions. They live in eucalyptus trees and are mostly nocturnal and eat certain types of eucalypt leaves exclusively. Some US zoos are capable of growing the necessary eucalypt leaves to feed them, but these trees do not occur naturally in the USA. PS - The koala is not a bear.
What is polar bear doing when their home is melting?
If the Arctic ice melts there is no land under the ice for polar bears. They will have to move to northern parts of Canada and other countries and try to adapt to a new habitat. They will have to change their hunting patterns (trapping seals under the ice) to different ways of catching land based prey. They will be regarded as intruders wherever they go.
Can polar bears be found in denmark?
It's entirely possible, since Tromso, Norway is located in what is considered the Arctic.
Is platypus a viviparous or oviparous?
No. Ovoviviparous means that the female produces eggs which hatch inside her body, meaning she actually gives live birth. Platypuses are oviparous, which is quite different from being ovoviviparous. They lay eggs, and incubate them for ten days.
Pictures of plants of frigid zones?
Animals living in the adapted to the cold condition very well by mostly having a thick coat under their skin, known as blubber. Such animals are penguins, polar bears, whales, seals, wolves, arctic foxes, arctic hares, reindeer, sables, arctic ground squirrels, lynxes, etc.
What do polar bears like to do in there spare time?
Animals do not need "fun" the same way humans do. Tying human emotion to an animal is not reasonable. Animals may enjoy something they are doing, but that is the extent of that issue. They do enjoying hunting, killing and eating prey. They are one of the only animals that will go out of their way to hunt and kill humans. That appears to be fun for them.
How do polar bears find and eat food?
Polar Bears are expert hunters. They usually hunt in areas that interface between ice and water. They rarely hunt in open water. They use a technique called "Still Hunting". They use their excellent sense of smell to locate a seal breathing hole and wait for the seal to appear. When the Seal comes out to breathe, the bear smells its breath, reaches into the hole with its front paws and drags it out of the water. They kill the seal by biting its head. They often raid the birth lairs of female seals and prey on the seal pups. They are extremely powerful and can even kill an adult walrus.
Polar bears find their food commonly with their excellent sense of smell. If they are hungry enough they will eat almost any animal they can get.
What is the classification of a polar bear?
Similar to its close relative the brown bear, but without a well pronounced shoulder hump, and a "Roman" nose.
How are humans killing polar bears?
because were creating more green house gases then there should be and making more global warming which is melting the ice so the polar bears cant get food. we arent dont it on purpose. we're just people. In other words, yes there are.
How did the polar bears get their white fur?
Polar bears do not have white fur, but semi-transparent fur. The polar bear's fur seems colourless and for many years, scientists worked on the theory that the individual hairs act as fiber optics bringing sunlight directly to the skin. This has recently been proven to be incorrect, and the hairs are not truly transparent, but contain keratin. Viewed side-on, the hairs appear colourless; viewed lengthwise (as if one was looking down a telescope) the hairs no longer appear transparent.
Polar Bears are white because the sun washed the color out of the sun and turned the fur folicoles white.
Actually this is common misconception. Polar bears do not have white fur, rather they have "transparent" hair or hollow tubes as hair that easily reflect the visible light spectrum and make them appear white. Mainly it is for camouflage in the bear's natural habitat, which is snow and ice in order to more easily hunt seals, fish and walrus.
