The main diet of Polar Bears is seals, primarily ringed seals, but they also catch other seal species and occasionally kill walruses, belugas and narwhals.
The female polar bear fasts while nursing her cubs, living entirely on the blubber she has stored in her body. She conserves her energy by resting and moving slowly and deliberately. Her cubs also need rest because of their young age, but they are well-nourished by her fat-rich milk.
Male Polar Bears will kill cubs. While females can sometimes fight off a male attack, it is much safer for her to avoid areas where males are present.
