Polar Bears Album

By Nicola Blaney

In this album I have put together some of the nicest pictures of polar bears taken by some of the worlds greatest photographers.

I wanted to show how the beautiful bears act in their own environment and how they are not that different from humans in some ways.

The polar bear is a bear native largely within the Arctic circle encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is the world's largest land carnivore and also the largest bear, together with the omnivorous Kodiak bear which is approximately the same size. An adult male weighs around 350–680 kg (770–1,500 lb), while an adult female is about half that size. Although it is closely related to the brown bear, it has evolved to occupy a narrow ecological niche, with many body characteristics adapted for cold temperatures, for moving across snow, ice, and open water, and for hunting the seals which make up most of its diet.

Polar bears are among the largest members of the bear family. Their white coat is actually composed of hollow hairs that reflect sunlight, producing a whitish/yellow camouflage in their Arctic habitat. Underneath the snowy coat is black skin, which helps them retain heat from sunlight.

Hope you enjoyed looking at the wonderful pictures in my album
