Polar Bear Description
  The polar bear is the largest bear in the world. It is also the largest land carnivore. Females are about half the size of males. Males reach their full size at 9-10 years old. Its black skin helps them to absorb sunlight and keep them warm. It has a double-dense coat that helps keep it warm and dry, even when it is swimming in the cold artic waters. Its hairs are also optical fibers, meaning hallow. This allows the hair to reflect light down to the black skin, where it is absorbed. It even has a layer of fat for insulation. In fact, it is so well insulated, that it can overheat and can often been seen sprawled out on ice sheets to cool down. Its body is very elongated and the head is longer and more wedge-shaped. The ears are much smaller than other bears which assist in conserving heat. Like all bears, its tail is short and stubby and it is plantigrade. Its feet are much larger in propotion to its body than other bears. Also, the soles have suction-cup like surface, so it can have a good grip on the slippery ice. It has very large canine teeth and its carnassials are highly developed. Its eyesight and hearing are similar to humans, but its sense of smell is the most highly developed. It can smell a seal under the ice. Polar bears have the ability to store incredible amounts of fat on its body to be used later. It survives on the stored fat for months at a time when food is scarce. When it goes into dormancy, it does not urinate or drink water as they can create water from the metabolism of fats and recycle their body wastes without using their kidneys. Unlike humans that are starving, its body metabolizes the fat and not lean body mass.
