Polar bears [[hibernate]] through much of the winter, usually in an excavated snow den. Their normal diet consists mainly of [[seal]]s, though in Canada they have been observed to take prey as small as [[lemming]]s. A large polar [[bear]] can stand 11 feet tall and weigh more than 700 pounds, and are one of the few natural predators of humans. For this reason they are greatly feared by arctic travelers. | Polar bears [[hibernate]] through much of the winter, usually in an excavated snow den.
