A polar bear is a great white northern bear (family Ursidae) found throughout the Arctic region. Except for one subspecies of grizzly bear, the polar bear is the largest and most powerful carnivore on land. It has no natural predators and knows no fear of humans, making it an extremely dangerous animal.

One important adaptation of polar bears to their unique climate is the transparency of their thick fur, which allows sunlight to pass through and reach their black skin, where heat from the sun is then absorbed. Another adaptation is polar bears’ use of only their front limbs when swimming, which is found in no other four-legged mammal.
