Description
Color: Pale brown

Adults are free living. Polyps are elongate, with an axial furrow extending almost to the polyp end. Several mouths are arranged along the axial furrow but do not occur outside the furrow. The septa are very densely packed and straight. The septa of lower orders are thick and solid, those of higher orders thin and perforated. Tentacular lobes are absent. The septal margins are coarsely ornamented with irregularly angular dentations. The corallum wall is perforated and covered with granulations. The coastae are almost equal in size; they are straight and distinct near the corallum margin, but less distinct near the center.

Similar species: It is similar to Ctenactis echinata, which has a single mouth.
