Polar Bears Have you ever wondered how Polar bears swim and never freeze to death?
Or what they eat? Polar bears live in the coldest parts of the world I know everyone with a brain probably Don’t be so rude to me it’s rude knows that but if you look further into these questions you will find out why Polar bears can love to be in the cold. I will be explaining these questions and more in depth in this paper so all your questions about Polar bears disappear and you can go to your mom and dad and say that you know everything about Polar bears, let’s dive right into it!
Polar bears live in some the coldest parts of the world. Polar bears live in Antarctica. According to Live Science,”Polar bears live in countries that ring the Arctic Circle: Canada, Russia, the United States (in Alaska), Greenland and Norway” (www.livescience.com). Polar bears like to live in cold weather well, because they are

One fact is that A Polar bear has black skin that traps heat and holds it for when the bears either swimming or sleeping. According to National Geographic,”But under their fur, polar bears have black skin—the better to soak in the sun 's warming rays”(www.nationalgeoghraphic.com). Polar bears have this so that they can trap heat in for when they need it the most. Specifically, Polar bears skin is good for many reasons. Another fact is that Polar bears grow hairs on the bottom of their paws so that when they are talking around on ice they don’t get as cold. According to SeaWorld,”The sole of a polar bear 's foot has thick, black pads covered with small, soft papillae. The papillae create friction between the foot and ice to prevent slipping. Long hairs growing between pads and toes also help prevent slipping”(www.seaworld.com). What this says that polar bears paws are very special unlike its brothers, it grows little bumps on the bottom of their paws for
This particular bear is a subspecies of the black bear. It has dark nose pads, white or creamy fur, brown eyes, and nearly white claws. This kind of bear is quite rare and maybe about 100 exist near British Columbia. It’s scientific name is the Ursus americanus kermodeii. The few white bears that live outside of British Columbia is only about one in a million.
Black bears have a medium to heavy frame with large ears and powerful limbs. The black bear has a coat that can differentiate from brown, cinnamon, blond, grey-blue, and of course, black. They can adapt to their environment easily but are normally found in forested areas. It has a diet that consists of fruits, buds, berries, nut, insects, and food lest by humans. They are incredible climbers that can use their claws to extract food from the trees.
the Kermode bears the might look like a polar bear or an albino but
Have you ever wondered why particularly in Alaska, bears need to stock up on food before winter comes? all the bears particularly in Alaska, need to stock up on food before winter comes because when winter hits food goes away. In the text it states " When the cold Alaskan winter hits, the bears’ food supply disappears. Temperatures drop, freezing the streams where tasty salmon swim. The berries that the bears snack on vanishes".
The grizzly bears adapt to their environment by hunting down their own food. They hunt down carcasses of caribou, moose calves, walruses, ground squirrels, and salmon as well
I. Introduction: Black bear is the smallest of the three species of bear, and is the only bear living in the eastern United States. Bears are very calm and independent animal. As a result they are usually lives in the wild. Black bear use forest as protection and food.
Unique Wolves If you visit northern Wisconsin, don't be surprised to hear the eerie and beautiful howl of wolves at night. They have returned after about 40 years of absence. By the 1950's, wolves had been driven out of their ancient homeland by ranchers and the federal government. Wolves killed livestock for food, so they were considered nuisances. But starting in the 1990's, the state reintroduced wolves to help manage the deer population.
As a consequence, these animals are now forced to spend more time on shore scavenging for food, often going without while awaiting new ice to form in the fall. There is also growing concern for polar bear cubs that are thought to be incapable of swimming the increasingly greater distances in open water between shrinking ice floes. As evidence, they offer the growing number of very young polar bear carcasses that they notice being washed up on shore. Many mother bears also appear to be dangerously thin and less able to fend for themselves and their young. This situation is quite noticeable among polar bears along the western shore of Hudson Bay, especially around the town of Churchill Manitoba, a location where polar bears traditionally spend the late months of fall foraging on shore awaiting the freeze-up, a freeze-up that now comes later each year.
The amount of arctic sea ice is declining more than ever. Polar bears are being greatly affected by the decreases in sea ice. (Doc A) This is affecting their diet because without enough sea ice it has been very difficult for them to catch seals to eat. Also, their population is decreasing due to the longer periods between hunts.
" Normal defensive attacks by female bears defending their young do not involve consumption of the victim's body." The grizzly bear was captured in a matter of minutes after the park ranger found mr Crosby's body on August 7 2105. The park evidence said
The nostrils are closed when the great mammal is under water to prevent internal drowning. As well as this, the hollow hairs (guard hairs) acts as a wetsuit. The blubber (fatty layer) keeps the bear warm as it moves through the freezing cold water. Polar bears are strong and fast swimmers and can obtain a swimming speed of approximately 10 kilometers per hour. This is a useful adaptation that helps them speedily escape when hunted by
They use the ice to rest on while hunting for seals, but since there is less ice it’s causing the polar bears to drown from exhaustion. Walruses can eat up to 200 pounds of clams each day. Clams are usually found near the continental shelf but with ice caps melting it is getting harder for walruses to find
Whereas in the wild the polar bear can wander endlessly without walking into a glass wall. Dolphins naturally travel up to 100
One of the main reasons polar bears are going extinct is because they aren’t getting the right amount of food they need to survive. Seals, the main food source for the polar bears, are animals that depend largely on the algae that grows on the ice of the Arctic. With the ice content slowly depleting, there isn’t enough seals to sustain the polar bear population. One of the
Climate change, specifically warmer temperatures, has extensively altered these habitats by reducing sea ice extent, thus affecting polar bears since they use it as a platform to travel, hunt, and rest. Changes in the timing of sea ice formation and break up limits the amount of time bears can feed off of seals during late and early summer, hence limiting the amount of fat they are able to store for later seasons. Lower rates of food intake and storage correlates to low reproductive rates, and since females do not have sufficient fat and mass required for successful parturition, they abstain from
