Polar bears are carnivores and their diet consists almost exclusively of seals. They primarily hunt ringed seals, but will also prey on bearded seals, harp seals, and occasionally hooded seals. Polar bears are opportunistic predators and will also scavenge on carcasses of dead animals, such as whales and walruses.
To hunt seals, polar bears use a variety of techniques. They may stalk their prey from a distance, hiding behind ice floes or rocks. When they get close enough, they will pounce on the seal and use their powerful jaws to deliver a fatal bite. Polar bears may also wait for seals to surface at breathing holes in the ice and then ambush them.
Life on Land
Polar bears spend most of their time on the sea ice, but they must come to land to den and breed. Dens are typically dug into snowdrifts or ice caves. Pregnant females will enter their dens in late October or early November and give birth to cubs in mid-December or early January. The cubs will remain in the den with their mother for several months until they are strong enough to survive on their own.
Male polar bears do not den, but they will often seek shelter from the cold in caves or under snowdrifts. They will also use this time to rest and conserve their energy.
