Majestic creature of the far north, the polar bear is the world's largest terrestrial carnivore. Its Latin name, Ursus maritimus, means 'sea bear': an apt name for this amazing species which spends much of its life in, around, or on the water - predominantly on the sea ice.

Why is the polar bear so important?
Large carnivores - those that are at the apex or top of the food chain - are particularly sensitive indicators of the health of an ecosystem. Polar bears help us gain an understanding of what is happening throughout the Arctic.
All recent indicators show that sea ice in the Arctic is melting at an alarming rate, a problem that needs to be addressed immediately if polar bears, and other species unique to the region, are to survive.

Arctic caribou and wild reindeer are truly circumpolar animals, linking regions and people around the globe.
