Coenosteum styles are small but distinctive. Colour: Dark or pale greenish-brown, or mottled dark green, usually with white polyps. Similar species: Stylocoeniella armata. Habitat: Large colonies (greater than 0.5 metres across) are usually found only in high latitude environments. Abundance: Uncommon, but more abundant than other Stylocoeniella species
