Polar bears are one of the only bear species known as marine mammals. That is because polar bears have features that help them adapt to the arctic weather. Their black layer of skin under the white fluffy fur allow them to stay warm, and their wide webbed feet make it easier to balance on ice because their weight is spread and the web helps them not slip. Also, unlike other bears, polar bears are carnivores. They eat mostly seals and sometimes walruses, because those are the only abundant sources that can sustain the large body weight and the population of polar bears.

Polar bears have adapted to polar regions within the arctic circle. Since they live in cold conditions and have adapted to that type of living, global warming is a big threat to their population. Global warming affects them by decreasing their population, making swimming more dangerous, and food scarcity. Polar bears only hunt during the cold seasons because there is no ice and they have to live on land, so in the summer they barely eat. But, if global warming takes away the winter season, they have no opportunity to hunt and eat, so they die. Because of the warm weather, more ice melts, so ice platforms are less accessible to polar bears. This makes the swims to the platforms longer. During this swim, there are big waves which make this swim very dangerous. If there are less …show more content…
Polar bears are at the top of the food chain, so they make sure animals, such as seals, do not overpopulate. As well as stopping overpopulation, they play an important role in the health of marine animals. Polar bears have also played an important role in the lives of Arctic people, culturally and economically. Polar bears have been hunted and used for food and clothing (ie. fur for coats) by many arctic people in the past. But now that the population is decreasing, hunters are being watched on how they treat polar bears; though they can still hunt some for food and

Polar Bears What is a Polar Bear? Sizable mammals colonizing tundra biomes, with fur adapting to colder climates are Polar bears. These mammals referred scientifically as Ursus maritimus meaning maritime bear since many consider them marine animals. The bears are carnivorous animals, with their main diet walruses, narwhals, beluga whales, and bowhead whales. With Polar Bears in the food chain remain on top, they do not have any predators except for male polar bears during competition in…

Summary Polar bears are an important arctic species that is in danger from climate change. A keystone species, polar bears are essential for a balanced ecosystem in the Arctic Circle. As the overall temperature of the earth is increases due to global warming and the greenhouse effect, the sea ice that polar bears live on for most of their lives is disappearing. Polar bears require sea ice to survive, as it is their hunting grounds and habitat. When the ice melts, polar bears are forced to move closer…

Polar Bear Polar Bears: Polar Bears are the largest bear in the world. Their fur is an overall white. The skin underneath is black. This is because they live in the arctic circle. Their fur and the color of their skin keeps them very warm. The paws on a polar bear are very large. The paws also have sharp claws that can be used to grip ice, or kill prey. The male polar bears fight with each other for the females. The polar bear cubs are born while the females are hibernating. She then raises it,…

Polar bears are beautiful, eye catching species but they are also one of the most dangerous species alive that is if you are near one. Polar bears are the most carnivorous of the bear species, they are tertiary consumers meaning they eat other secondary and primary consumers. Polar bears are marine mammals and are mostly located near areas of water and ice floes in Arctic Tundra. Polar bears feed mostly on the fat of ice-dependent seals which are ringed or bearded seals, the remains of these seals…

The Polar Bears Preamble: Polar bears, known as Ursus maritimus, are carnivorous, marine mammals that thrive in the cold Arctic Oceans and stand as one of the most endangered species of animals on the planet. They are classified as ‘marine mammals’ because they spend a significant portion of their lives on the sea and ice of the Arctic regions. Polar bears are also quite proficient swimmers as they can swim with their front paws at speeds exceeding 4km/h- which is, in fact, an impressive speed for…

Evolution Essay

which live in the North and possess black fur have very low chances to survive, that is why most animals, including polar bears, seals possess white fur and can easily hide on the white background of snow. The color of skin and fur is very important for survival, because it enables animals to hide, protect themselves or hunt being undetected. We can write a Custom Research Paper on Evolution for you!

Nowadays, it seems like the world is getting warmer and things are not looking to pretty for the animals that are living in the wild. It is looking a lot worse for polar bears, monk seals, and salmon. Years ago it was expensive for biologist to get the data to see how much energy an animal wasted on catching his next meal .Luckily, that little device you see on someone when you are at the gym (known as accelerometers). Present the possible answers that scientist have been in search of for years.…
