The polar bear's 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 ocean.
Polar bears are found throughout the circumpolar Arctic. They're frequently seen along or near coasts and on islands, but they spend the majority of their lives on the sea ice.

Life on sea ice

Sea ice is vital to polar bears. It provides a platform for them to hunt, live, breed, and in some cases, create maternal dens.

But sea ice is more than a simple platform: it is an entire ecosystem inhabited by plankton and micro-organisms, which support a rich food chain that nourishes seals, that in turn become prey for polar bears.

It is the very foundation and defining characteristic of the Arctic marine ecosystem.

Life off the sea ice

As sea ice decreases at a rate of about 4.6% a decade, some polar bears at the southern edges of the species' range are spending five to six months on land, with very few seals to eat.
Without sea ice and seals, polar bears are left to search for other food sources. This can lead them into communities, where garbage dumps, sled dog yards and human food storage offer easy pickings. Bears in communities often create conflict between bears and people – bears threaten the safety of people and their property. Communities, government and WWF are working together to keep both bears and people safe.

What's happening to sea ice?

As the climate warms, Arctic sea ice is disappearing. Almost every summer, the amount of remaining ice gets smaller. The oldest ice has essentially disappeared.
This time-lapse video from NASA shows how the extent and age of sea ice has changed since the 1980s.

Follow polar bears

Follow polar bears as they wander the fjords and ice of Svalbard, Norway, hunting for seals and raising their cubs. Each bear is fitted with a satellite collar, and their locations are updated regularly.
