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).
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 ...
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.
The list of animals that polar bears consider prey is long, but up until recently it wasn't known to include white-beaked dolphins. A team of scientists working in icy Svalbard, Norway in 2014 ...
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.
An isolated group of polar bears living in southeast Greenland has surprised scientists with its ability to survive in a habitat with relatively little sea ice. Polar bears face existential threat ...
Marine mammals are aquatic mammals that rely on the ocean for their existence. They include animals such as sea lions, whales, dugongs, sea otters and polar bears. Like other aquatic mammals, they do not represent a biological grouping. [26] The humpback whale is a fully aquatic marine mammal.
Polar bears take particular advantage of these situations and are able to locate the belugas using their sense of smell. The bears swipe at the belugas and drag them onto the ice to eat them. [ 34 ] They are able to capture large individuals in this way; in one documented incident, a bear weighing between 150 and 180 kg was able to capture a ...
