There are many different animals that live in the Atlantic Ocean, including manatees, sea lions, humpback whales, Atlantic ghost crabs, starfish, catfish, green sea turtles, gray Atlantic seals, penguins, shrimp, redfish, flounders, sea trout and tarpon. There are also a lot of plants that live in the Atlantic Ocean, including living coral reefs filled with sand dollars and sea stars as well as seagrass, algae and seaweed.
The Atlantic Ocean is comprised of saltwater and is quite warm when compared with other oceans, providing ideal conditions for a host of diverse animal species. As the Atlantic Ocean is the second-largest ocean in the world, covering approximately 20 percent of the Earth's surface, it is able to support a multitude of animals as their habitat.
Many sea mammals, such as whales, dolphins and seals, migrate to and from the Atlantic Ocean each year. During the summer months, these species travel to colder waters to find rich feeding grounds and to build up their bodily stores of fat for the coming winter. They return from the colder Polar regions to the warmer waters of the Atlantic Ocean in the winter months in order to mate and rear their young.
