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.
Harp seals usually feed on a variety of fish and other invertebrates. A study has revealed that the harp seals' diet consists of at least 67 species of fish and 70 species of invertebrates. Harp seals prefer to feed on cod, which has resulted in a steady decline in their population.
