Lobophyllia robusta

Yabe and Sugiyama, 1936

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.

Habitat: Most reef environments.

Abundance: Uncommon.

Similar species: Lobophyllia flabelliformis

Taxonomic note: Source reference: Veron (2000). Taxonomic reference: Yabe and Sugiyama’s original description/specimens. Additional identification guide: Nishihira and Veron (1995).
