Sea Anemone
Sea Anemones are named after a terrestrial flower called the Anemone because of their appearance. They are capable of moving to avoid predation. 1
Clownfish cover themselves in Sea Anemone mucus to avoid getting eaten by them and Hermit Crabs like to attach them to their shells to ward off predators. Some crabs will also use Sea Anemones to collect food by stealing what the Sea Anemone catches. 1
