POLAR BEARS

Scientific name

Ursus maritimus

Polar Bear Diet

Unlike other bear species, polar bears are almost exclusively meat eaters (carnivorous). They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe.

Polar Bear Habitat

Polar bears live in Alaska, Canada, Russia, Greenland, and some northern islands owned by Norway, such as Svalbard. Polar bears depend on the sea ice, which forms above the open waters where their seal prey lives.

Polar Bear Characteristics

comparatively slim body with long neck.

narrow head with small eyes and outer ears.

paddle-like paws with webbed toes.

short tail (7 to 13 centimetres)

five short, non-retractable claws.

body covered with hair, with the exception of the lips, the nose and part of the soles of the feet.

Polar Bear Body Structure

Polar bears are stocky, with a long neck, relatively small head, short, rounded ears, and a short tail. The male, which is much larger than the female, weighs 410 to 720 kg (900 to 1,600 pounds). It grows to about 1.6 metres (5.3 feet) tall at the shoulder and 2.2–2.5 metres in length.

Polar Bear Significance

Importance of polar bears. Polar bears are at the top of the food chain and have an important role in the overall health of the marine environment. Over thousands of years, polar bears have also been an important part of the cultures and economies of Arctic peoples.

Answer:

The polar bear (Ursus maritimus) is a hypercarnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the largest extant bear species, as well as the largest extant land carnivore.[5][6] A boar (adult male) weighs around 350–700 kg (770–1,540 lb),[7] while a sow (adult female) is about half that size. Although it is the sister species of the brown bear,[8] it has evolved to occupy a narrower ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice and open water, and for hunting seals, which make up most of its diet.[9] Although most polar bears are born on land, they spend most of their time on the sea ice. Their scientific name means "maritime bear" and derives from this fact. Polar bears hunt their preferred food of seals from the edge of sea ice, often living off fat reserves when no sea ice is present. Because of their dependence on the sea ice, polar bears are classified as marine mammals.[10]

Because of expected habitat loss caused by climate change, the polar bear is classified as a vulnerable species. For decades, large-scale hunting raised international concern for the future of the species, but populations rebounded after controls and quotas began to take effect.[11] For thousands of years, the polar bear has been a key figure in the material, spiritual, and cultural life of circumpolar peoples, and polar bears remain important in their cultures. Historically, the polar bear has also been known as the "white bear".[12] It is sometimes referred to as the "nanook", based on the Inuit term nanuq.[13]
