Females usually dig dens in snowdrifts on southerly facing slopes. Some dig earthen dens that later become covered by snow. |
Polar bears inhabit arctic sea ice, water, islands, and continental coastlines.Polar bears prefer sea ice habitat with leads and polynyas, next to continental coastlines or islands.The ocean temperatures in the Arctic are about -1.5°C (29°F) in summer. In winter the ocean temperatures can drop to -2°C (28°F), at which point seawater begins to freeze. | ||
Polar bears need an average of 2 kg (4.4 lb.) of fat per day to obtain enough energy to survive. A ringed seal weighing 55 kg (121 lb.) could provide up to eight days of energy for a polar bear. |
