On tropical reefs it is uncommon and forms only small encrusting colonies 761. 3 species Stylocoeniella armata (Hemprich & Ehrenberg 1834) Stylocoeniella cocosensis Veron 1990 Stylocoeniella guentheri (Bassett-smith 1890) Family POCILLOPORIDAE Gray 1842 Madracis Milne Edwards & Haime 1849 II (Cosmopolitan, widely distributed throughout most temperate and tropical seas: 42-160 m.

In the Indo-pacific there is probably only one reef-building species (M. kirbyi), occurring from Taiwan south to the Philippines 768, Thailand 186,744, Borneo, Sulawesi, Moluccas, New Guinea and Australia: Great Barrier Reef 761. This species is rare and inconspicuous. Of the ahermatypic species, Madracis kauaiensis is endemic to the Hawaiian Islands 186. There are, in addition, a number of non-reefal species of Madracis which occur in temperate waters 761] 12 species Madracis asanoi Yabe & Sugiyama 1936 Madracis asperula Milne Edwards & Haime 1850 Madracis brueggemanni (Ridley 1881) Madracis decactis (Lyman 1859) Green Cactus Coral 45
