These anemones are commonly known as aggregating anemones because they can rapidly clone themselves, and live in large clusters of genetically identical individuals. Clonemates from different clusters are actually enemies. Anemones on the edges of the cluster develop large white nodules that are full of stinging cells. They use these stinging cells to ward off members of another clone group.
