What do Seals Eat? Seals find the foods that they need in the water around them, which is why you will only find them where there is plenty of water. Their primary sources of food include fish but they will consume just about any type of meat they can get in the water. Other types of food that they enjoy include squid, octopus, and shellfish. Sometimes food sources are low due to the big ships fishing for such items in the same waters as the seals hunt.
Their favorite foods include the ringed and bearded seal which is plentiful in the Arctic. Polar bears will eat sea birds and their eggs if available where they live. Their diet occasionally includes smaller whales (such as the beluga) and the walrus. Their eating habits include scavenging for dead animals including different types of whales and fish. The polar bear is an important part of Arctic food chain.
