Which marine animals live in the Atlantic Ocean?

The Atlantic Ocean supports a diverse array of marine life, ranging from microscopic plankton to large marine mammals and commercially significant fish species.1

Fish and Shellfish

The Atlantic is home to a wide variety of fish, many of which are vital to global fisheries. Important commercial species include:
* Groundfish: Cod, haddock, and hake.23
* Pelagic species: Herring, mackerel, tuna, and menhaden.23
* Shellfish: Lobster, shrimp, sea scallops, surf clams, ocean quahogs, and blue mussels.23

Marine mammals in the Atlantic include various cetaceans and pinnipeds:
* Dolphins and Whales: Many species of dolphins and whales inhabit the ocean, with whales often migrating to tropical waters to breed.14
* Seals: Harp seals are found in the northwest basin, among other seal species.14
* Manatees: These are found in tropical regions, though their numbers have dwindled.14

The ecosystem also supports sponges, sea anemones, horseshoe crabs, mollusks, and sea turtles. Additionally, the Sargasso Sea hosts large communities of crustaceans and fish within its masses of gulfweed.1
