This anemone possesses an abundance of dense tentacles that may grow as long as 12.5 cm. Its 200 tentacles are long, delicate and covered with a continuous spiral band of white nematocysts. The mouth is located in the center of this large mass of tentacles. Colors of the B. annulata range from an almost transparent pale brown to a dark brown. Color is produced by zooxanthellae in the tissues of the anemone.
