SPECIES- Ursus Maritimus, Polar Bear, lord of the Arctic. Lives in an area of five million square miles of snow and ice. From Siberia to Alaska and across Canada, Greenland and the Islands north of Norway, he is the master of all living things except man. It lives in the brutal cold, ice, and snow. The temperature can plunge down frequently to -40 degrees and sometimes even lower but that does not bother the polar bear because of its color-less skin and layer of insulation fat. Its range extending
Polar Bears Life Span It is believed that polar bears live an average of 15 to 18 years, though some bears have tagged in their early 30s. In some zoo’s bears have been known to live up to the mid 30s. There is only one individual bear that has been known to have lived up to the age of 40. Biologists believe that starvation is the leading cause of death for sub adult bears, which is probably the reason that when bears are in captivity (a zoo) they live longer. Population Polar bears live in Russia
my bad days very well comparatively, and I am able to enjoy my good days without difficulty. When I was suffering from depression however, I did not have any good days, and my bad days were more than bad, they were hopeless. I have suffered from bi-polar depression since I was ten. This means that I could be having a perfectly fine day (for someone with depression) and without warning I could have an onset of serious depression, and become so unsociable and bitter that I would drive everyone away from
Polar bears are big, white bears (sometimes darker fur) that live in very cold regions like around the artic poles. There are 21,000 to 28,000 Polar bears alive that are known. Polar bears swim in water and are carnivores, they eat fish . Polar bears feed mainly on ringed seals and bearded seals. Depending upon their location, they also eat harp and hooded seals and eat carcasses of beluga whales, walruses, narwhals, and Bowhead whales. A polar bears' stomach can hold up to 15% to 20% of its
Habitat Polar bears prefer to live in extremely cold artic climates. They live only in the Northern Hemisphere, on the arctic ice cap, and they spend most of their time on coastal areas. Polar bears are widely spread in Canada, extending from the northern arctic islands south to the Hudson Bay area. They are also found in Greenland, on islands off the shore of Norway, on the northern coast of the former Soviet Union, and on the northern and northwestern coasts of Alaska in the United States. Physical
The Polar Bear is a huge and powerful animal, they are also the top predators in the Arctic and the world's largest land living carnivore. But sadly there is not so many of Polar Bears that live in the Arctic for it is found to be an endangered spies. Polar Bears are endangered/ threatened due to the burning fossil fuels such as coal and oil releasing high amounts of carbon dioxide into the atmosphere. Carbon dioxide is a greenhouse gas that traps the sun's energy and causes the Earth’s climate to
majestic creatures in the world the polar bear. From its brown bear ancestry, the predator evolved to be a master of a harsh and unwelcoming ice kingdom. Intelligent, adaptable and fierce, the polar bear learned how to survive in a place that offers few comforts to any creature. But now that very environment is in flux. And so is the polar bear’s fate (Nature). Polar Bears are very different from other bears. Polar bears are very large bears compared to Black bears. Polar bears weigh anywhere between 330-1700lbs
survival with the top predator of the artic, the polar bear. Polar bears inhabit the circumpolar arctic regions. They live near their primary food source in the ice packs of the artic. The bears inhabit the circumpolar North, which would consist of Canada, Alaska, Greenland, and other regions in the artic. The temperatures range between -40°F to -50°F in the winters and summer temperatures stay around -29°F. When summer reaches the artic the polar bears are forced to travel to the remaining ice
characteristics of a polar bear is its color. The fur shafts themselves are not white. The shafts actually lack pigmentation and are transparent which allows them to scatter and reflect light resulting in ideal camouflage in a world of ice and snow. * Polar bears paws are also well adapted for the environment in which they live. They can measure up to 304 mm. (12 inches) in width. These large paws allow polar bears to better distribute their weight more evenly across ice surfaces. * Polar bears do not
Polar bears are one of the Earth’s largest and most powerful carnivores. These bears are dependent on sea ice as their primary habitat and are thus found on the Arctic coasts of North America. The scientific term used to describe polar bears, Ursus maritimus translates to sea bear because polar bears spend most of their lives on the Arctic ice. A common misconception the public holds is that polar bears are white; their fur is actually consists of two transparent layers: hollow guard hairs and an
One of the main differences between the Polar Bear and other types of bears is where it lives. When the Polar Bear was first discovered, it was very unusual that it would live in this extremely cold part of the world. There is information to suggest that millions of years ago the evolution process began. Evolution is a process of changes that take place as something exists over time. Researchers believe that a large number of brown bears became isolated from the rest of the population during a time
breaker for the future of the polar bear. Are humans responsible for the future of the big white bears that roam around on ice all day trying to survive? Maybe we are, maybe we are not, but polar bears are diminishing due to fluctuating environmental changes, gas and oil activities like drilling in the Atlantic Ocean, and their survival rate is decreasing as a result of starvation. Climate change has been one of the top leading causes of sea ice loss. According to Polar Bear International a study found
Introduction: In this report I will be using the Polar Bear (Ursus maritimus) as my chosen species. The Polar bear is the largest land living apex carnivore in the world where males can reach a mass of over 450 Kg and females between 150 Kg to 350 Kg. Instantly recognizable by their white fur coat which is technically transparent where it is the reflection of the snow that gives the Polar bear its beautiful white coat. As a Polar bear’s skin is black allowing for some heat from sunlight to aid in
foods were enough to fill the needs of wild polar bears to live. The problem they had to find an answer to was if the polar bears were able to adapt to the land based food and be able to balance their calories to not starve. Their hypothesis was that the polar bears would be able to adapt to the different type of food when they were fasting. This hypothesis was proven false because the polar bears that were fed food were losing weight as fast as the polar bears that weren't fed. The independent variable
has social effects on aspects such as health, food production, and growth. Climate change causes tremendous spread of certain infectious diseases and increased death rates related to heat waves. Climate change would affect the health conditions of polar bears through malnutrition, high death rates, and frequent occurrence of diseases and injuries due to extreme changes in weather. In addition, high concentration of ozone gases at ground level causes cardio-respiratory diseases in urban areas (Richard
the National Oceanic and Atmospheric Administration, which has played a major role in the conservation of the polar bear species, one of the mammals most adversely affected by the recent climate changes. As more research has been conducted regarding the polar bears, scientific name Ursus Maritimus, the conclusions have been shocking. In 2008, the Department to the Interior listed the polar bear species as “threatened” under the Endangered Species Act of 1973 awarding it some protections mandated
Have you ever seen a Polar bear? Maybe you saw them on tv ads, if you watch tv sometimes. I’m talking about Coca-Cola ads. Where there are white polar bears that are drinking Coca-Cola on a sea ice. I think that not only me but also you as well would like to see a polar bear in our lifetime. Well, they don’t drink Coca-Cola, but their main food is ring seals. They usually live in the North Pole and South Pole or in the Arctict Ring. im gonna to talk about the North Pole’s polar bear because all of
The marine mammal the polar bear lives in the countries that make up the Arctic Circle, which would be countries like Canada, United States but only the state of Alaska, Russia, Norway, and Greenland. Roughly 60% of the world’s polar bears live in Canada. Polar bears do not live in the Antarctic. At birth, polar bear cubs weigh about 16-24 oz. When born the female cubs are slightly smaller than the male cubs. Polar bear cubs are born small and helpless, with their eyes closed. By eight months
In 2008 the Polar bear was put on the endangered species list, they were the first to be placed on this list primarily due to global warming. Many will argue with this fact, but as we will discover through this document, global warming is real and is in fact affecting the lives of the polar bears. Polar Bears depend on the sea to freeze over which enables them to hunt seals. The bears have a short season to hunt in order to gain enough fat to survive the entire year. With the decline
These days more and more animals and plants are becoming extinct. That means they must be protected in order to maintain the number of animals or plants, which are threatened by extinction. The question is how can we protect them? Right now polar bears and other animals are struggling more than ever to survive. There are a few things we can do to help. Stopping pollution, stopping wild animal hunting, and stopping deforestation are the main factors in keeping them alive. To begin with, pollution
