Plants in the ocean include kelp, seaweed and a variety of algae species. Additionally, some warm and shallow portions of the ocean harbor sea grasses. Numerous animals survive by eating these green plants, including green sea turtles and invertebrates, such as sea urchins. The ocean also has its share of large herbivores, such as manatees. According to Save the Manatee Club, manatees consume 10 to 15 percent of their body weight each day.

Predators, including barracudas, sharks and stingrays feed on other creatures of the ocean, especially squid, small fish and crustaceans. Crustaceans are important scavengers of the ocean. Crabs, lobsters and shrimp often feed on dead animals and small bits of organic matter.

Some of the ocean’s largest animals feed upon some of the ocean’s smallest species. For example, basking sharks, whale sharks and blue whales feed on plankton and krill. Coral are tiny animals that form large reefs that become habitats for other species. Coral filters organic bits of food from within the water column.
