Polar bears consume nearly every part of their prey, including the blubber, meat, skin, and internal organs. The blubber is particularly important for energy storage and insulation.
In some cases, polar bears may partially bury or hide their kills under the snow or ice to protect them from scavengers and to ensure a future source of food.
When seals are scarce, polar bears may switch to alternative food sources, such as seabirds, bird eggs, or vegetation. However, these alternatives are not as nutritionally rich as seals and are typically a last resort.
