The burrowing anemone grows up to 8 cm in diameter. It lives in a self-constructed wrinkled felt-like tube which may be buried quite deeply in the sand. Several rows of feeding tentacles emerge from the tube and may be salmon-coloured, brownish, creamy or purple. The outer tentacles are longer and used for foodcapture and defense. The inner tentacles are shorter and held more erect. These are used for food manipulation and ingestion. Burrowing anemones only emerge to feed or reproduce, and they are nocturnal in their feeding habits.
