Polar bears (Ursus maritimus) are primarily found in the Arctic region, where they inhabit a variety of ecosystems and environments. Their range typically includes:

1. Sea Ice: Polar bears are most closely associated with sea ice, particularly in the polar regions of the Arctic Ocean. They are strong swimmers and depend on sea ice as a platform from which to hunt seals, their primary prey. They use the ice as a vantage point for spotting seals in breathing holes or breaking through the ice to access seal dens.

2. Pack Ice: Polar bears are adapted to living on pack ice, which is a mix of floating sea ice and open water. They use the ice as a platform to hunt for seals, which they capture when the seals surface to breathe.

3. Coastal Regions: Polar bears are often found along the coastlines of the Arctic Ocean and adjacent seas. Here, they may scavenge carcasses of marine mammals, forage for vegetation, or hunt seals that come onto the ice.

4. Tundra: In some parts of the Arctic, particularly during the summer months when sea ice has retreated, polar bears may venture onto the Arctic tundra. This environment is less common for them, and they are less effective hunters in terrestrial ecosystems.

5. Offshore Islands: Polar bears can be found on various Arctic islands, especially when they are in search of food or other resources.

Polar bears are highly adapted to their extreme environment and have evolved various physiological and behavioral traits to survive in the Arctic. Their primary prey is seals, and they are excellent swimmers, capable of covering long distances in the frigid waters. However, the loss of sea ice due to climate change is a significant threat to polar bear populations, as it limits their access to seals and their primary hunting grounds, making their conservation a matter of concern.
