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.
They are extremely powerful seals and that is part of why they are such great hunters. They have very sharp teeth and they are also the fastest of all the seal species out there. In addition to consuming other seals they love to eat penguins as well while on land. They consume a variety of fish as well in the waters. The only predator that they have in nature is the killer whale. Ross seals also live in the colder regions but they are very unknown.
