Characters: Colonies usually consist of a few corallites but may become large and hemispherical. Corallites are large, phaceloid and mostly monocentric. Septa have tall sharp teeth. Polyps are thick and fleshy, with a rough surface. Colour: Blue-grey, sometimes with pale valley floors or septo-costae. All corallites of the same colony have the same colour. Similar species: Lobophyllia hemprichii, which has smaller, less fleshy polyps. Lobophyllia flabelliformis has corallites of similar size and fleshy appearance, but these are always flabello-meandroid. Habitat: Most reef environments. Abundance: Uncommon
