Polar bear
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.

Survival of the fattest: Why the climate crisis is making it hard for polar bears to get enough calories
To survive, polar bears need two things: seals to eat, and a platform of sea ice from which to hunt them. Pregnant bears, in particular, must get very fat from hunting seals before they hibernate, as they may not eat for eight months: they rely on stored fat for the energy they need to produce and nurse cubs, meet their own needs and travel back to the ice in spring.
Read moreWhy 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.

Follow in the footsteps of polar bears
With the help of polar bear researchers, WWF is following polar bears' travels in the Arctic.

WWF is working around the Arctic to secure a future for polar bears.
Learn moreHow we work
Addressing human-wildlife conflict
WWF's global work to reduce human-wildlife conflict is based in our Netherlands office.
Innovating in polar bear research
WWF catalyzes innovation. From extracting DNA from snowy pawprints to supporting tests of infrared camera systems for counting polar bears, WWF works to increase efficiency, reliability, and cost effectiveness of Arctic research.
Preventing polar bear conflict in Canada
In the community of Arviat, WWF supports a polar bear patrol and pilot projects with food storage containers, solar-powered electric fencing and diversionary feeding stations.
Preventing polar bear conflict in Greenland
Since 2015, Greenland’s first polar bear patrol has worked through the polar bear migration season to keep the community of Ittoqqortoormiit safe. Each morning the polar team patrols the community on ATVs, using deterrence measures to frighten bears away. WWF also guides the community and government on improving polar bear safety.
Preventing polar bear conflict in Russia
Since 2006, polar bear patrols have been operating with the support of WWF-Russia. The patrols conduct polar bear monitoring and research; and protect villages from polar bears and prevent human - wildlife conflict.
Protecting polar bears across borders
WWF addresses conservation of polar bears at the local, national, and international levels. We support community initiatives such as polar bear patrols and contribute to planning and implementing range-wide conservation plans.
Reducing polar bear conflict in Alaska
Along the northern coast of Alaska, WWF supports several active polar bear patrols and education programs.
Reducing polar bear conflict on Svalbard,Norway
Svalbard is a hotspot for polar bear tourism - and conflict. The local government is working with organizations like WWF, scientists and the tourist sector to find the best methods for managing conflict.
Supporting polar bear research on Svalbard
WWF is supporting Norwegian scientists on Svalbard who are researching the local polar bear population.
Surveying polar bears in Western Hudson Bay
WWF supports polar bear surveys using an innovative mark-recapture technique that does not require tranquilising the bears.

Beluga
Belugas are extremely sociable mammals that live, hunt and migrate together in pods, ranging from a few individuals to hundreds of whales.
Bowhead whale
This predominantly Arctic species is associated with ice floes. Its movement patterns are therefore influenced by the melting and freezing of the ice. The bowhead has suffered from severe over-exploitation that has seen its range shrink considerably since the 17th century.
