The primary food of polar bears is mainly seals, specifically ringed and bearded seals. Polar bears are carnivorous and rely heavily on the blubber and fat obtained from seals, which are crucial for their survival in the Arctic environment. The bears hunt seals by waiting near breathing holes or breaking through sea ice to catch them. Due to the seasonal nature of seal availability, polar bears also need to build fat reserves, which they do during the ice-covered months of the Arctic. This high-fat diet is vital for maintaining their energy levels and insulating them in frigid temperatures.
