The main characteristics of the species of the polar bear

A dense layer of underfur traps a layer of air next to the skin to keep them warm. Most polar bears elsewhere will never have access to these alternatives, except for the marine mammal carcasses that are important wherever they occur.

Where they live and the robustness of their habitat determines their survival. Spectacled bears prefer the warm, humid, and foggy clouds that are above the rainforest floor at higher elevations.

They named the newly discovered region after a polar star which guided them to the end of the earth. If the present rate of hunting and deforestation continues, these bears may become extinct. They are medium sized bears that have a more round figure than their cousins. These bears sleep in remote locations where they den, usually in high elevation.

These areas, known as the "Arctic ring of life", have high biological productivity in comparison to the deep waters of the high Arctic. One of the first things they learn upon emerging from the den is to climb trees for protection from predators, including other bears. The polar bear kills the seal by biting its head to crush its skull.

Among young males in particular, play-fighting may be a means of practicing for serious competition during mating seasons later in life. The polar bear was previously considered to be in its own genusThalarctos.

Sloth Bear melursus ursinus For a long time, sloth bears were confused with another tropical animal called a sloth. But when they wander nearby, roaming dogs owned by villagers have been known to attack them. Males can weigh — kilograms — lband females 35 —82 kilograms 77 — lb.

Combined with the fact that pandas digest a very low percentage of what they eat, they must consume huge quantities to absorb sufficient nutrients.

For example, large furry feet and short, sharp, stocky claws give them good traction on ice. Their arms and legs are black along with a band extending from their front arms around their back.

Laws have been written to protect the sun bear, but enforcement is lacking. When walking, the polar bear tends to have a lumbering gait and maintains an average speed of around 5.

In a more restricted sense, tundra denotes a special type of vegetation association. Antarctica The most striking fact about the Antarctic continent is its almost complete glaciation.

They can easily become conditioned to eating human food, and may eventually stop foraging in the forest and become a dangerous nuisance to humans.

In southern climates they do not hibernate. They live at the top of the world in the Arctic Circle.Polar Bears Physical Characteristics Size.

The polar bear is the largest land carnivore. Male polar bears (boars) grow two to three times the size of females (sows).

The Spectacled bear is a mid-sized species of bear. Overall its fur is blackish in color, though bears may vary from jet black to dark brown and to even a reddish hue.

The species typically has distinctive beige-coloured marking across its face and upper chest, though. On 15 Maythe United States Department of the Interior listed the polar bear as a threatened species under the Endangered Species Act, citing the melting of Arctic sea ice as Class: Mammalia.

The polar bear’s white coat serves as camouflage while hunting on snow and sea ice. General Description Polar bears have longer necks, narrower heads and smaller ears compared to other bears. Life History Growth and Reproduction. In Alaska, black rockfish become sexually mature at 6 to 8 years of age (38–42 cm).

Black rockfish produce betweento 1, eggs per season. Physical Characteristics: Polar bear fur can appear pure white, yellow, or even greenish, depending on light conditions. The outer fur called ‘guard hair’ is actually clear and hollow (like a tiny glass tube), which was once believed to trap the sun’s heat and light.
