Polar Bears Have Natural Heating Ability
The arctic circle is a cold and unforgiving wasteland, to live there you have to able to regulate your body temperature. According to Polar Bears International, polar bears are built for these harsh environments. Polar bears are animals that have to face this tough environment every single day of their lives. The polar bear uses many ways to insulate its body from the inside to the outside.
Charlotte Lindqvist, Assistant Professor of Biological Sciences at Buffalo College of Arts and Sciences, states “Gene functions that had to do with nitric oxide production seemed to be more enriched in the polar bear[s]” (qtd. In Hsu). This means that the polar bear is able to pump more blood throughout its body without …show more content…
According to Sea World, a marine and wildlife research organization, the polar bear has a layer of fat up to four and a half inches thick. This layer of fat keeps them so well insulated almost no heat escapes. Polar bears are so well insulated they tend to overheat on occasion (SeaWorld).
On top of the blubber, the polar bear has tough hide. Polar bears hide is dark black, according to The National Wildlife Federation, an organization that investigates wildlife and animal behavior. The black tint of their skin absorbs the heat of the sun, while also trapping the heat, keeping them warm on even the coldest of days. Even though the only visible sign of this skin pigmentation is on the nose, the rest of their body is the same color under the abundant amounts of white fur (NWF).
The fur of the polar bear is hollow (Polar Bears International). The fur is hollow so it can trap heat in-between the hairs, so the bear can stay warm while doing nothing at all. The hairs are also all various lengths so there is more surface area to trap heat between every fiber of hair. On top of the short hair layers, is a top fur coat made from the same thick hair. Polar bears are so well insulated they tend to overheat on occasion (SeaWorld). The polar bear uses these techniques to not only stay alive, but to thrive in extreme

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 company has said on its website that all the fur and material used in making the jackets are easily trackable to a location where the fur is taken in a humane manner. Also, the down that is used in making the coats comes from a third party that comes from the poultry industries and have not come from birds that have been hand plucked individually. The products are made to protects against the coldest climate. The reason why they choose to make their products from down is because its known to be the best insulator which provide 3 times as much warmth mores that the regular insulator. The coyote fur that’s is being used around the hood
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".
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.
Depending on the bears location, what season it is, and the sex and age of the individual their home can vary with males usually overlapping the territory of many female bears. The less food supply, water, and shelter in the area, the larger range a bears home becomes. With the bears strong build, they are able to travel anywhere in the forest. With long sharp claws, they can climb trees when feeling threatened. They have very
So far in the book Brian’s Winter by Gary Paulsen, Brian is stuck in the forest for the winter, and is adapting to the cold atmosphere that is the forests of Canada, and by this food become scarce for Brian and it becomes extremely difficult for him to find food, and then kill it as well, along with food being more scarce and the pond slowly beginning to freeze up. Brian also needs to build a new shelter for multiple reasons. One reason is because of how his food is situated along with the fire he is burning to cook it a bear one day approached the food and fire, and it was right next to Brian and he at one point attacked the bear in order for Brian to protect his food, but the bear attacks Brian, leaving bruises and scrapes throughout his body so he needs to restart his food placement,
Grizzly bears are a dominant species in their niche. They are located in the north america deep into the forest. There favorite food is salmon. There ecosystem is filled with all sorts of other wildlife. Grizzly bears are also efficient in the ecosystem.
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
Projects based on bears also focus on the asiatic black bear, the sun bear, and the sloth bear. Bears are carnivores, meaning they eat both meat and vegetation. The bear’s diet consists of things like berries, nuts, grass, fruit, insects, roots, and bulbs. They will hunt small animals and brown bears specifically, when near a coast, will feed on fish, particularly salmon. Other bears, like the polar bear scavenge for carcasses of the beluga whale, walruses, narwhals, and bowhead whales.
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
The polar bear seems to be very malnourished and needs help. The journal cover says, “Staying Alive” in white capital letter and underneath that it says to “Cut greenhouse-gas emissions now and we can still save the polar bear”. Which suggest that climate change affects polar bears greatly and that we can
