Polar bear den entrance with the head of a mother polar bear (Ursus maritimus). This bear, the world's largest land predator, is found throughout the Arctic circumpolar regions, although its range is limited by the extent of the pack ice. This mother polar bear has two cubs who were born during the winter. The cubs and their mother have recently emerged from their den at the start of spring. The cubs will stay with their mother for between a year and a half and two and a half years. Photographed in March in Wapusk National Park, Manitoba, Canada.
