Corallimorpharia is an order of marine cnidarians closely related to the true sea anemones (Actiniaria). They are mostly tropical, with a narrow column topped with a wide oral disc. The tentacles are usually short or very short, arranged in rows radiating from the mouth. Many species occur together in large groups.
