What is the classification of a polar bear?

Answer 1

Similar to its close relative the brown bear, but without a well pronounced shoulder hump, and a "Roman" nose.

Answer 2

A large bear related closely to the brown bear, found in the Arctic regions. Most carnivorous of bears, feeding mainly on seals.
The polar bear (Ursus maritimus) is a bear that is native to the Arctic Ocean and its surrounding seas. It is one of the world's largest carnivores found on land, a title it shares with the Kodiak Bear. The adult male weighs from 880-1,500 pounds, while an adult female is about half that size. The polar bear is closely related to the brown bear, but it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet. Polar bears are an endangered species, and global warming is contributing to their decline.
Polar bears are a species of bear living in the freezing cold waters or land of the Arctic


Polar bears are black bears with clear fur; their fur is actually hollow. They live in cold climates and range in the arctic. They eat a variety of seals, fish, etc. They only have one or two cubs per year. Normally solitary creatures.
big white bears that live in the north
A regular bear species once came to somewhere cold and they were forced to adapt. Hence, the wondrous polar bear.

Answer 3

To stay alive, to preseve its species, as well as cut down on the population of the seals, and walruses, like all predators do with game. No penguins, penguins are in the south pole, polar bears on the north pole.

Answer 4

as it names says its the Bear family, it is the largest of the land carnivores (largest fond was over 1000lb or about 450kg)

Its closest relatvie in the bear tree is the brown bear found in the US & other places.

Answer 6

An arctic bear that lives at the Arctic. They have a white coat, but have black skin so that they can soak up as much heat as possible from the sun, and they have white fur to blend in with the snow.
Big, white, furry, mean, and hungry.

The polar bear is the largest terrestrial carnivore, being twice as big as the Siberian Tiger.[29] It shares the title of largest land predator (and largest bear species) with the Kodiak bear.[30] Adult males weigh 350-680 kg (770-1500 lbs) and measure 2.4-3 m (7.9-9.8 ft) in length.[31] Adult females are roughly half the size of males and normally weigh 150-249 kg (330-550 lb), measuring 1.8-2.4 metres (5.9-7.9 ft) in length. When pregnant, however, they can weigh as much as 499 kg (1,100 lb).[31] The polar bear is among the most sexually dimorphic of mammals, surpassed only by the pinnipeds.[32] The largest polar bear on record, reportedly weighing 1,002 kg (2,210 lb), was a male shot at Kotzebue Sound in northwestern Alaska in 1960.[33] By way of comparison, this huge male is estimated to weigh around 1800 lbs.

Polar bears have evolved unique features for Arctic life, including furred feet that have good traction on ice.

Compared with its closest relative, the brown bear, the polar bear has a more elongated body build and a longer skull and nose.[19] As predicted by Allen's rule for a northerly animal, the legs are stocky and the ears and tail are small.[19] However, the feet are very large to distribute load when walking on snow or thin ice and to provide propulsion when swimming; they may measure 30 cm (12 in) across in an adult.[34] The pads of the paws are covered with small, soft papillae which provide traction on the ice.[19] The polar bear's claws are short and stocky compared to those of the brown bear, perhaps to serve the former's need to grip heavy prey and ice.[19] The claws are deeply scooped on the underside to assist in digging in the ice of the natural habitat. Despite a recurring internet meme that all polar bears are left-handed,[35][36] there is no scientific evidence to support this claim.[37] Unlike the brown bear, Polar Bears in captivity are rarely overweight or particularly large, possibly as a reaction to the warm temperatures of most zoos.

The 42 teeth of a polar bear reflect its highly carnivorous diet.[19] The cheek teeth are smaller and more jagged than in the brown bear, and the canines are larger and sharper.

Polar bears are superbly insulated by up to 10 cm (3.9 in) of blubber,[34] their hide and their fur; they overheat at temperatures above 10 °C (50 °F), and are nearly invisible under infrared Photography.[38] Polar bear fur consists of a layer of dense underfur and an outer layer of guard hairs, which appear white to tan but are actually transparent.[34] The guard hair is 5-15 cm (2.0-5.9 in) over most of the body.[39] Polar bears gradually moult from May to August,[40] but, unlike other Arctic mammals, they do not shed their coat for a darker shade to camouflage themselves in the summer conditions. The hollow guard hairs of a polar bear coat were once thought to act as fiber-optic tubes to conduct light to its black skin, where it could be absorbed; however, this theory was disproved by recent studies.[41]

The white coat usually yellows with age. When kept in captivity in warm, humid conditions, the fur may turn a pale shade of green due to algae growing inside the guard hairs.[42] Males have significantly longer hairs on their forelegs, that increase in length until the bear reaches 14 years of age. The male's ornamental foreleg hair is thought to attract females, serving a similar function to the lion's mane.[43]

The polar bear has an extremely well-developed sense of smell, being able to detect seals nearly 1 mi (1.6 km) away and buried under 3 ft (0.91 m) of snow.[44] Its hearing is about as acute as that of a human, and its vision is also good at long distances.[44]

The polar bear is an excellent swimmer and individuals have been seen in open Arctic waters as far as 200 mi (320 km) from land. With its body fat providing buoyancy, it swims in a dog-paddle fashion using its large forepaws for propulsion.[45] Polar bears can swim 6 miles/hour. When walking, the polar bear tends to have a lumbering gait and maintains an average speed of around 5.5 km/h (3.5 m.p.h.).[45]

Answer 7

Polar bears are carnivorous bears that can be called sea bears and white bears. They have black skin with white fur above it. The white fur is actually made up of clear hollow hairs. They have large necks compared to other bears. They are aggressive when they need food. They are especially aggressive when another male wants to mate the same female as they would like. They primarily eat seals.

Answer 8

The polar bear is a mammal and often considered a marine animal. It has adaptations that help it survive in very cold weather conditions.

Answer 9

the job of a polar bear is to get food to feed their cubs and to protect their cub's

Answer 10

Function of the bear’s fur is to insulate or to conserve heat.

Polar Bear Digestive System 1 The polar bear digestive system is similar to the digestive system of humans. 2 2 kg (4.4 pounds) of fat is at least required by a polar bear in a day to survive and move in the arctic. 3 The polar bear digestive system takes 20 hours to digest the food (seal blubber). 4 The polar bear faeces (poop) is liquid, gelatinous and dark brown in color when its food in take is mainly seal blubber.
