Polar bears. Many think of polar bears living in Antarctica as if they are living in a winter wonderland. Sadly this is not the case. Polar bears everywhere are on a daily struggle to survive. They have a shortage of ice time to hunt and fatten up for the winter. Because of the shortened ice time due to global warming polar bears are under more stress‚ starving‚ and dying. They are struggling over something they cannot control. Polar bears living more south‚ for example in the Hudson Bay region‚

The Polar Bear’s fur is extremely thick and it traps the heat so well‚ you can’t see one in inferred vision. This is good because the retention of heat keeps it permanently warm. It does not lose body heat as other animals and people do‚ and it would not be recognised by an inferred scanner‚ such as used when searching earthquakes and other devastated sites for survivors. The Polar bear would not be detected so this shows how well the bears fur keeps its body warm‚ especially in icy cold freezing

The icy habitat allows polar bears to hunt for their primary prey - seals. The powerful species’s

wondered how the polar bear keeps warm in the arctic? That is thanks to fat. The polar bear has nearly 10 cm of fat under their fur. The Polar bear gets its fat by eating seals. With its Astonishing appearance‚ handy hunting technique‚ harsh habitat the polar bear is an impressive animal. Polar bears have a rather astonishing appearance. Most of these traits are not for show but rather Warmth‚ friction‚ or hunting. The size of a polar bear’s head is smaller than most bears. The smaller head

availability of crops for the hares. However‚ the opposite of this may happen and the population of their prey or availability of their food source could drop‚ therefore affecting and decreasing the numbers in that specific species. For prey‚ in this case the hares‚ their numbers could drop due to an increase in their predators meaning more of them are required to supply for the needs of the predator. If there is competition for food for the Canadian Lynx‚ and another species use hares to hunt in the

today’s enlivenment for polar bears isn’t the best. Polar bears are finding harder to service with ice melting earlier in the spring and refreezing later in the fall. With larger oil companies moving closer into the arctic it is affecting the bears even more. Already having to deal with clement change and ice melting faster‚ big oil has moved in and poring toxins in to the environment. With the working of the oil rigs‚ oil is spilling out into the water poising the polar bears food sources. Other

food‚ escape predators and attract mates. The cheetah has the speed necessary to run down its prey‚ monarchs secrete a poison that deters predators from feasting on it and the hummingbird has a very long tongue for extracting nectar from flowers. These are some of the more obvious adaptations. However‚ if we take a closer look‚ we see that all organisms have several adaptations for living and surviving in their environment. The polar bear is a great example of adaptation. This bear is very different

more about is the Ursus maritimus‚ commonly known in North America as a Polar Bear. Ursus maritimus is the Polar Bear’s scientific name which means sea bear; it received this name because it is heavily involved in the water and is the only bear considered to be a marine mammal. There is one documented Polar Bear that undertook a 426-mile swim that took nine days and did not rest on land; they are phenomenal swimmers. Polar Bears are found in the wild in the Circumpolar North‚ which consists of countries

Are polar bears facing extinction because of global warming? [pic] By: Aieron Levy Could global warming be killing polar bears? The weather temperature is rising because of global warming‚ this is due to changes in the entire Arctic eco system. Scientists suggest that warmer temperatures mean less lack of ice that polar bears depend on for hunting. As their normal habitat gets hotter it goes down in size‚ this consequence leads to fewer polar bears. For the polar bear‚ which

believe that polar bears are endangered as a species now or in the future? Why or why not? Yes‚ I do believe that polar bears are endangered as a species now and might be in the future. It is because the extinct has been increasing throughout or to a great percentage. Polar bear population as per the data of 2010 was ranging from 20000 to 25000. A female can only deliver only 1 to 3 per littler for every 3 years and its life expectancy is 25 years this threatens the existence of polar bears in the future
