Sea anemones look like plants, but they are really meat-eating animals. Sea anemones usually spend most of their lives in one place, but some have the ability to move. If they do move, they can only travel three to four inches an hour. In the centre of the sea anemone is their mouth. The sea anemone eats small fish and shrimp,they must wait for their food to swim by then they sting it with their tentacles, and then push it into their mouth. Some even bury themselves in the mud.
