The term MARITIME CARNIVORE can be summarized as a four-letter word: SEAL. Seals are semi-aquatic mammals that live in the ocean and feed on fish, crustaceans, and other marine animals. They are found in all oceans of the world and are well adapted to their aquatic environment, having webbed feet and a streamlined body. Seals are an important part of the marine ecosystem, helping to maintain balance in the food chain.
