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.
Those adaptions are what keeps the polar bear species alive today. These bears hunt for their food and use the freezing water to get to some of their prey. To assist with swimming, they have a four inch layer of blubber that lets them stay bouyont. Along with their huge bodies, these carnivores have long powerful claws that grip the ice. When swimming, they have webbed feet to assist in swimming.
This is due to osmosis like what occurred in the tap and distilled water. When the bear came into contact with the salt water solution, it was subject to a hypertonic solution. To achieve equilibrium, water left from within the bear and entered the solution. IF the bears, after the last day, were again placed in distilled water, the bears would likely grow in size once more due to what occurred when the bears were originally in distilled water. Osmosis would cause water molecules from the solution to enter the bear, increasing its size.
The Arctic fox has a thick layer of body fat (physiological adaptation) for insulation and food storage, for times when prey are few. These animals also have countercurrent heat exchangers in their paws(physiological adaptation). Blood entering their paws heats up the blood that is exiting, preventing the core of the fox to be cooled by heat loss from extremities. Another behavioural adaptation is observed during blizzards, or extremely cold weather, when the Arctic Foxes dig tunnels into the snow to shield themselves from the icy winds and obtain insulation
Polar bears have a thick layer of fat called blubber which is about 11 cm thick. This also helps the bears to survive in the freezing conditions. Not only on land, but the thick layer of fur coat and blubber helps them as they spend a great amount of time swimming in the freezing waters of the Arctic. Blubber is a thick layer of fat that helps prevent sea mammals from getting too cold. Blubber in depth, is an extra digested food stored in the form of adipose tissue, which contains molecules called lipids.
Introduction: Due to moving the arctic snow fox to the tropical rainforest, the snow fox will experience tremendous amount of evolutionary impact. So due to speciation, the formation of a new species due to evolution, it will be called a Forest Fox. The Arctic Snow Foxes environment is very frigid. They feed on the weakest of animals, and even feed of of the leftovers of other animals like polar bears. One of its predators is a polar bear, but because of its white fur, it is very hard to spot.
This implies that they cannot survive without the ice. The dependence of the large mammals on the frozen floating homes, especially for the rapid access of ringed seals, indicates their survival and breeding probabilities are based on the sea ice conditions. Due to their remarkable degree of specific adaptations to life on the frozen Arctic ocean, the bears are very successful. As a result of this, the polar bears are more vulnerable to the effect of climate change. (Fitzgerald, Kevin T (2013).
It definitely create a large possibility for them to swallow those furs and develop a hairball. • Eating prey Many dogs usually have prey instinct due to which they tend to eat them whole including feathers and furs. Since hair is indigestible, it will remain inside their stomach. If their digestive system is not that strong, then those furs will end up staying on their digestive tract where it will trap or block other decaying faeces. As a result, there is always an opportunity of occurring a great health risk since toxic gases and substances from the rotting materials will be reabsorbed by the bloodstream.
There are usually air holes in the ice through which mink or otter can go in or out. Such holes, leading down through the covering snow and through an opening in the ice, have been described for the mink. Those used by otters are of course correspondingly larger. The “slip,” as the otter travels in the snow, may be a foot or more wide, and is easily distinguished from the one made by mink. However, it should be remembered that a beaver will also come out of the water into the snow, and will make a wallowing trough.
This climate is one of the harshest on earth. What was the Innu diet? In the winter the Innu needed the food for survival. So they hunted caribou, seal, walruses, beluga whales, musk oxen, artic fox, artic hare, polar bears and narwhals. Summers were spent fishing and hunting caribou in the inner regions of the artic.
