polar bears

Polar bears are large marine mammals native to the Arctic, well-adapted to cold environments. They have thick white fur and a thick layer of fat underneath to insulate against freezing temperatures. As apex predators, they primarily hunt seals, relying on their keen sense of smell and powerful limbs to catch prey on sea ice. Polar bears are excellent swimmers, capable of covering long distances in search of food. Their survival depends heavily on sea ice, which they use as a platform for hunting and resting. Climate change threatens their habitat, making them an important symbol of Arctic ecosystem health.
