With its Astonishing appearance, handy hunting technique, harsh habitat the polar bear is an impressive animal. Polar bears have a rather astonishing appearance. Most of these traits are not for show but rather Warmth, friction, or hunting. The size of a polar bear's head is smaller than most bears. The smaller head helps minimize heat loss. (Hanel 16) Also, the polar bear's ear are also small. If the ears were any larger they would easily freeze off. (Hanel 17).

The water is about -30 f. (http://www.livescience.com) It so cold, huge icebergs that are called floes, are created. most of the year polar bears will live on these.
