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).
Inuit hunters most often hunt juvenile whales which, compared to adults, are safer to hunt and have tastier skin. Ringed seal and bearded seal are the most crucial aspect of an Inuit diet and is often the largest part of an Inuit hunter's diet.

Polar bears hunt primarily at the interface between ice, water, and air; they only rarely catch seals on land or in open water. [69] The polar bear's most common hunting method is still-hunting: [70] The bear locates a seal breathing hole using its sense of smell, and crouches nearby for a seal to appear. When the seal exhales, the bear smells ...

The upper value, 5.0, is unusual, even for large fish, [7] though it occurs in apex predators of marine mammals, such as polar bears and killer whales. [8] As a point of contrast, humans have a mean trophic level of about 2.21, about the same as a pig or an anchovy.
There are about 130 living and recently extinct marine mammal species such as seals, dolphins, whales, manatees, sea otters and polar bears. [36] They do not represent a distinct taxon or systematic grouping, but are instead unified by their reliance on the marine environment for feeding.
A hunt begins with a chase followed by a violent attack on the exhausted prey. Large whales often show signs of orca attack via tooth rake marks. [83] Pods of female sperm whales sometimes protect themselves by forming a protective circle around their calves with their flukes facing outwards, using them to repel the attackers. [89]
The polar bear is well adapted for hunting Arctic whales and calves. Bears are known to use sit-and-wait tactics as well as active stalking and pursuit of prey on ice or water. Whales lessen the chance of predation by gathering in groups. This however means less room around the breathing hole as the ice slowly closes the gap.
