Polar Bears
Polar bears live in the Arctic regions where they wander the ice sheets and swim in the chilly water. Their fur is insulated to help keep them warm as their hidden black skin absorbs the sun's rays. Female polar bears even build dens in snow drifts to stay warm and protected. It is in these dens where the females give birth to twins in the winter. The cubs will stay with their mother for about 28 months while they learn basic survival needs. One of the survival needs mother polar bears teach their young is how to hunt for food. Polar bears have white fur which allows them to blend in with the snow and ice when hunting their prey. These powerful mammals feed on seals and other carcasses when food is scarce.
Beluga Whales
Beluga whales, also known as white whales, are easily recognizable for their unique and vivid white color. Baby belugas or calves, however, are not born white but grey or brown instead and turn white only when they mature around age 5. These mammals live in small groups called pods in the Arctic and subarctic waters. Belugas that live in arctic waters "migrate southward in large herds when the sea freezes over". Beluga whales are very friendly and have an expanded language of noises that they use to communicate. Beluga whales feed on fish, crustaceans, and worms.
