About Me

The polar bear is a semi-aquatic marine mammal that depends mainly upon the pack ice and the marine food web for survival. It has adapted for life on a combination of land, sea, and ice.Scientists and climatologists believe that the projected decreases in the polar sea ice due to global warming will have a significant negative impact on of this species within this century.

My Interests

The polar bear (Ursus maritimus), a bear native to the Arctic, is the apex predator within its range. Its thick blubber and fur insulate it against the cold. Its fur is hollow and transparent but usually appears as white or cream coloured, thus providing the animal with effective camouflage. Its skin is actually black in color, however. The bear has a short tail and small ears that help reduce heat loss, as well as a relatively small head and long, tapered body to streamline it for swimming.
