Polar bears are the Arctic’s top predators, perfectly adapted to life on sea ice. With thick fur, a dense undercoat, and a layer of blubber, they stay warm in extreme cold. Their powerful sense of smell helps them detect seals—often their main prey—up to a kilometer away. Polar bears are strong swimmers, capable of covering long distances between ice floes. However, they face growing threats from climate change, as melting sea ice reduces their hunting grounds and access to food. Classified as vulnerable, their future depends on global efforts to reduce carbon emissions and protect fragile Arctic ecosystems from further decline
