POLAR BEARS:

Polar bears are excellent swimmers, but their preferred habitat is on top of the ice that covers Arctic seas much of the year.They have special adaptations, or features that help them live in that habitat, like webbed feet, a layer of fat, fur that helps them blend in and dry off, and black skin to absorb the sun's heat.Polar bears rely on sea ice to access the seals that are their primary source of food, as well as to rest and breed.They mainly eat ringed seals, but may also eat bearded seals. Polar bears hunt seals by waiting for them to come to the surface of sea ice to breathe. When the seal nears the surface, the polar bear will bite or grab the seal and pull it onto land to feed. They also eat walruses and whale carcasses.The global polar bear population is currently about 26,000, according to the International Union for Conservation of Nature (IUCN). That's a rough estimate, but scientists have determined with 95% certainty that between 22,000 and 31,000 polar bears exist on Earth today.
