Polar bears are uniquely tied to one of the most remote environments on Earth. Rather than living on land, they roam a shifting world of sea ice, moving vast distances across the Arctic in search of food, mates, and safe places to rest.
Polar bears live across the Arctic Ocean and its surrounding regions, including Alaska, Canada, Greenland, Svalbard, and Russia. They depend on sea ice (pack ice) as their primary habitat for hunting seals, travelling, and breeding, with most populations staying within the Arctic Circle where ice persists year-round or seasonally.

Polar bear origins
Polar bears are a relatively young species, thought to have evolved around 150,000 years ago. Scientists have since discovered just how closely related they are to brown bears. In a landmark study published in PNAS, researchers used DNA from an ancient jawbone found in Norway to show that polar bears evolved from brown bear ancestors. Over time, they adapted to survive in the extreme conditions of the Arctic. While this specialisation allows them to thrive in icy environments, it also makes it far more difficult for polar bears to adapt to the rapid pace of climate change.
Understanding the polar bear habitat
The polar bear habitat is one of the most specialised in the natural world. Although they are bears, polar bears are classified as marine mammals because they spend most of their lives on sea ice rather than land.
Their habitat includes:
- Floating sea ice (their primary hunting platform)
- Coastal tundra (especially when ice retreats)
- Snow-covered land used for maternity dens.
Sea ice is the key to everything. It supports the Arctic food chain, giving polar bears access to seals, their main source of energy and without it, survival becomes much more difficult.
Where do polar bears live in the Arctic?
Polar bears live across the frozen seascape of the Arctic Ocean and its surrounding coastlines. Their range spans five countries:
- The United States (Alaska)
- Canada
- Greenland
- Norway (Svalbard)
- Russia
Unlike land-based species, polar bears rely heavily on pack ice. This floating ice acts as a platform for hunting for seals, resting, and long-distance travel. Because of this, polar bears move with the seasons, following the expansion and retreat of sea ice across the Arctic.
If you’re wondering where do polar bears live in the world, the answer is simple: only in the Arctic. There are no wild polar bears in the Southern Hemisphere.
Where do polar bears live on a map?
On a map, the polar bear range forms a ring around the Arctic Ocean. Key regions include:
- Northern Alaska (Beaufort and Chukchi Seas)
- Northern Canada (Hudson Bay, Baffin Island, Arctic Archipelago)
- Greenland’s coastline
- Svalbard (Norway)
- Arctic Russia (Kara Sea, Laptev Sea, East Siberian Sea)
Ice regions of the polar bear
There are four main ice regions where polar bears can be found:
Seasonal ice
This region lies between Canada and Greenland, extending into Hudson Bay and the Labrador Sea. Here sea ice melts completely during the summer months, forcing polar bears to fast until the ice returns.
Polar Basin divergent ice
This region covers the northern edge of Russia and includes the icy area surrounding Svalbard, Norway. Here, sea ice retreats in the summer and extends in the winter. During warm weather, polar bears may retreat to land in search of food.
Polar Basin convergent ice
This region covers the north and eastern shores of Greenland as well as the Northern Beaufort Sea and the Queen Elizabeth Islands. This area stays iced over for much of the year, meaning the polar bears here fare well compared with those in other regions.
Archipelago ice
This region consists of the sea ice extending throughout the Northwestern Passages and into the Viscount Melville Sound. Polar bears here can hunt on land as well as on ice.
Polar bears' home ranges can be enormous. Some individuals travel thousands of kilometres annually, following the movement of sea ice and prey.
How do polar bears survive in the Arctic?
Life in the Arctic is extreme, but polar bears are perfectly adapted to it.
Over thousands of years, polar bears have evolved to live in this environment in ways few animals can:
- Thick blubber provides insulation in freezing water
- Dense fur traps heat and repels moisture
- Large paws act like snowshoes and powerful swimming paddles
- An exceptional sense of smell allows them to detect seals from a great distance

Why polar bears matter in the Arctic ecosystem
Polar bears sit at the top of the Arctic food chain, making them essential to the health of the ecosystem.
Their presence helps regulate seal populations and maintain ecological balance, while also acting as an important indicator of environmental change.
Seeing a polar bear in its natural habitat
Few wildlife encounters compare to seeing a polar bear in its natural habitat which is undeniably vast, silent, and breathtakingly remote.
On carefully guided expedition voyages, guests may witness a polar bear navigating the shifting sea ice, a glimpse into a world few people ever experience.
Moments like these stay with you long after the journey ends, offering not just a rare encounter, but a deeper connection to the Arctic and its future.
Polar Bear FAQs
What is a polar bear’s habitat?
Polar Bear's habitat consists of sea ice, coastal regions, and denning areas used for breeding.
What ecosystem do polar bears live in?
Polar bears live in the Arctic marine ecosystem, relying on sea ice as their primary habitat.
What do polar bears eat?
Primarily seals, especially ringed and bearded seals.
How many polar bears are left in the wild?
Estimates suggest around 22,000–31,000 individuals globally.
How has the polar bear adapted?
They’ve adapted with thick fur, blubber, strong swimming ability, and specialised hunting techniques.
How far south do polar bears live?
Some populations reach as far south as Hudson Bay in Canada during certain seasons.
How do polar bears protect themselves from the cold?
Insulation from blubber and dense fur, along with behavioural adaptations like sheltering from wind.
Do polar bears hibernate?
Only pregnant females enter a denning period; others remain active year-round.
Are there polar bears in Antarctica?
No, polar bears only live in the Arctic.
Are polar bears endangered?
They are classified as vulnerable due to climate-driven habitat loss.
