    What do the polar bears’ diets consist of?

    Polar bears are highly carnivores, meaning that 90% of their food comprises meat. They mainly eat seals with bearded and ringed faces because the arctic is the home of thousands of them, making them readily available. They can be a target when they emerge to breathe or dump the ice out to lay down.

    Polar bears hunt primarily between water and ice; they seldom pursue seals inland or in open water. They can live in sea ice. Ringed seals weigh around 130 pounds, which makes them ideal for sows to hunt. However, the bearded seal could consider as much as the polar bear that weighs about 600 pounds. Adult males weighing between 770 and 1100lbs are typically too big for sows to hunt and can be food for boars.

    But, boars can also catch prey larger than themselves, like walruses that weigh between 1300 and 3300 pounds, which is more than twice the weight of a bear.

    Adult bears consume the calorie-rich seal’s skin and fat because it’s very digestible, while the cubs eat the protein-rich meat. They also take food scraps from bears’ kills when food is scarce, or they’ve never been able to capture something.

    Because most animals can outrun or outswim polar bears, their diet is supplemented with eating dead seal carcasses or walruses.
