Group 1: Mammals
The huge polar bear is one of the largest land carnivores in the world. Its coat, which varies in color from pure white to shades of yellow, blends in well with its snow-covered environment.
FOOD & HUNTING
polar bears feed mainly on seals they wait for them to come to the water surface to breathe, or stalk them while they rest on the ice, The seal is killed by crushing blow to its sckull. Polar bears eat everything-they cannot afford to leave anything edible behing. In the late summer and early autumn polar bears will patrol the coastal areas looking for whale and whale carcasses.Sometimes ten to twenty bears may be feeding together. At this time of the year thier diet is more varied including such land mammels a lemmings artic foxes and eider ducks. like polar bears also eat vegetation.
HABITS
Polar bears are found throughtout the polar region but they spend most of their time along the southern edge of the icecap on the coastal land nearopen water. They are solitary animals and are active at all times of the year.
Polar bears are also excelent swimmers. They cruise through the water at speeds of up to six miles per hour,using their front legs to propel them, with their hind legs trailing behind. With their eyes open and nostrils closed, they can dive under water as well remaining submerged for two minutes. When they emerge they immediatel shake the water from their coats before it frezzes.
BREEDING
Springtime is the mating season for polar bears, with most activity taking place in April. Males seek available females; most females breed every third yeat separting from their young. In October and November, the bears dig dens in the sonw or tundra. The dens usually located on south-facing slopes of hills where northerly winds pile up large amounts of snow. The dens are used for giving birth. Young are born in November or December and weigh only 16-32 ounces. They are hairless, blind, and deaf. They first emerge from the den in March or April. They will remain with their mother into the third spring of their lives.
DID YOU KNOW?
Polar bears have a very acute sense of smell; they can smell carrion,such as a dead whale, from 20 miles away, and can sniff out seal dens that are covered with snow. The black nose of a polar bear on the sonw can be seen from six miles away on a clear day through binoculars. It has been said that, when stalking seals, the polar bear will cover it's nose with a paw to escape detection. The temperature inside a polas bear's den can be 40 degreed warmer than the outside temperature.
