The Dahlia anemone is a beautiful animal with a short column and short tentacles. It is a powerful predator, it can catch and devour active pray such as prawns. It comes in a variety of different colours and usually has attractive banding on its tentacles. Dahlias are often seen singly but sometime form dense patches at the bottom of shallow rocky gullies. The surge conditions in such gullies can make it difficult for pray to avoid the dahlia’s tentacles. The Dahlia anemone can grow up to 20cm across. It is a common species all along the South coast of Ireland.
