The female seals have grayish black backs and silver-gray bellies. Pups are black at birth. Most females, pups, and young males leave the Bering Sea in late November to migrate as far south as southern California and Japan. Mother fur seals leave for eight to 10 days at time soon after the pup is born and hunger often drives the scared pup into the water. Despite the fledgling fur seals' bravery and quick learning, five to twelve percent of all pups die during their first month of life.
Hookworm causes anemia in the small sea creatures, and they eventually starve.
The Russian arctic fox is a fox subspecies and does not turn white at all. Instead, she remains gray-brown. The fox's preferred territory ranges from arctic and alpine tundra to ice covered seas. The distance traveled is incredible when the fox's size is considered, for he is no bigger than a house cat. Arctic foxes are scavengers and hunters eating almost anything available that others leave behind.
