The polar bear (Ursus maritimus) is a large bear native to the Arctic and nearby areas. It is closely related to the brown bear, and the two species can interbreed.The polar bear is the largest extant species of bear and land carnivore, with adult males weighing 300–800 kg (660–1,760 lb).
The key danger for polar bears posed by the effects of climate change is malnutrition or starvation due to habitat loss.Polar bears hunt seals from a platform of sea ice. Rising temperatures cause the sea ice to melt earlier in the year, driving the bears to shore before they have built sufficient fat reserves to survive the period of scarce food in the late summer and early fall.
The Arctic fox (Vulpes lagopus), also known as the white fox, polar fox, or snow fox, is a small species of fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. [1] [8] [9] [10] It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as ...

Pinnipeds and polar bears have longer guard hairs forming the most visible fur; [1] polar bears' guard hairs are hollow. Some considerations in judging the quality of an animal's coat: Colour (coat colour other than those allowed in the breed standard results in disqualification)
Like many mammals, grizzly bears are covered in thick fur. Fur is a thick growth of hair that covers the skin of almost all mammals. It consists of a combination of oily guard hair on top and thick underfur beneath. The guard hair keeps moisture from reaching the skin; the underfur acts as an insulating blanket that keeps the animal warm. [1]
The polar bear population is estimated to be around 16,000 in Canada, which is more than 60% of the world’s population. The bears are said to be most active during the day and have a keen sense ...
The fur measures about two and one-half inches in length. It is used mainly for muffs and neck, shoulder pieces. [4] The trapping of fishers is restricted in many States leading to it becoming a more uncommon type of fur in comparison to the mink. Fisher fur is more durable and water resistant than other types of fur such as fox. [7]
