The beadlet anemone is a compact sea anemone with a smooth body and short, thick tentacles. It lives on areas that are exposed during low tide. When exposed, it retracts its tentacles, making it look like a ball of black-brown mucus. It has blue knobs filled with poison just under the tentacles, which it spouts when touched. This toxin is not poisonous for people. The beadlet anemone may appear lazy however anemones are known for vicious fighting among themselves. They keep competitors at a distance with their extra long fighting tentacles.
