The Polar bear's scientific name is //Urus maritimus//. The polar bear has an elongated body and a long neck. Their fur can be pure white, creamy yellow, or light brown depending on the season. Polar bear's feet are five-toed paws, each toes have thick, curved claws used for grabbing prey. They have 42 teeth and their canine teeth grasp prey and tear hides. Polar bear's tails are usually 7 to 12 centimeters long. The skin on the polar bear are black and they completely shed and replace their fur in May or June. Polar bears are most active the first third of the day and least active the last third of the day. Adult female polar bears with their cubs hunt about: Adult male polar bears hunt about: Polar bears are sleeping or resting if they are not hunting. Polar bears lie out on the ground or ice on warm days and lay on their back with their feet up in the air. On cold days they curl up and cover their muzzle area. In the winter some polar bears make temporary dens or find natural shelters to stay warm and may use these shelters for many months at a time. Ringed and bearded seals are what polar bears mainly feed on. Depending on where the seals are they eat harp and hooded seals and also feed on carcasses of beluga whales, walruses, narwhals, and bowhead whales. At the age of four to five years old femals polar bears reach sexual readiness and male polar bears are about six years old when theyre ready to mate. Males do not successfully mate until eight to ten years old or more. Polar bears are located in artic regions such as: Polar bears are found in the Artic. Polar bears and their tracks have been reported almost as far north as the pole which is not good because the northern Arctic Ocean has little food for them. In the southern range they are limited by the amount of sea ice that forms in the winter. Polar bears would rather travel on sea ice and they must have ice to hunt seals. Polar bears are visitors to southern Labrador, Newfoundland, and Norway and can reach the Gulf of St. Lawrence and Bering Sea during years with heavy pack ice. Many of the polar bears are found near land masses around the edge of the polar basin where the continental shelf makes conditions great for hunting.

Polar bears were put on the endangered species list on May 15th of 2008. There are about 20-25,000 polar bears today. Global warming and warmer temperatures are causing the decrease of polar bears and threatening them. When it is warmer weather the polar bears have to wait longer for the ice to return and some scientists think that is the reason they are finding polar bears dieing from starvation and cannibalism. If we can stop global warming that will help the polar bear.

The Endangered Species Act was passed under the Nixon Administration. On December 28, 2973 it was signed into law. The purpose of this act is to protect the endangered species and their habitats. Plants, vertebrate, and invertebrate creatures were included in this act also. Two federal agencies work in tandem to protect wildlife and conserve natural resources. United States Fish and Wildlife Service and the National Oceanic and Atmospheric Administration. If I could propose one amendment to the Endangered Species Act it would be to raise money and to find a cure save all the endangered species and their habitats because some animals do help their habitat and if there are no animals in that habitat the habitat will eventually die.
