Polar bears are amazing animals. They are threatened, so we must help them. They are usually about 6 to 9 feet long. They are carnivores and they eat seals, walrus, beached whales, caribou, and seaweed. They live up north in the icy tundra. You can't find polar bears in the south pole, only the north.

They can live in Alaska, Canada, Greenland, Norway, and Russia. They live in ice and snow, but that's not a problem. These bears have some cool ways to stay warm with 2 different layers of hair and thick fat.

During the winter, many bears hibernate. Polar bears do not, but their body functions do slow down at this time. This is called "Winter Sleep," as the bears can easily be awakened. A mother bear can give birth and nurse her young while in her winter sleep.
