About
Ctenactis echinata is a solitary fungiid widely distributed across the Indo-Pacific. It is a medium to large elongated oval disc reaching about 25 cm in length and 10 cm in width. An axial furrow runs along most of its length with usually a single mouth, though occasionally there are more. The primary septa are thick and densely set with large triangular teeth, and between them lie one to five smaller, lightly toothed secondary septa; a large individual may carry more than a thousand septa. The costae on the underside are poorly defined and bear long arborescent or cylindrical spines in radial rows. Colour is usually pale brown. It occurs on reef flats and slopes and in lagoons down to 20 m and is common throughout its wide range. As a scleractinian it is on CITES Appendix II, and the IUCN rates it Least Concern.
