No fewer than 79 species of fish have been documented in the marine park. They use a wide variety of habitats. Most are typically saltwater or estuarine species, but about a dozen are typical of freshwater habitats.

Of note, species such as the American Sand Lance, the Capelin, and the Atlantic Herring live in schools, and serve as readily accessible food for several marine mammals. Some whales literally “graze” these fields… of fish!
