(Ehrenberg, 1834)

Colonies are encrusting to massive and frequently over one metre across. Corallites are cerioid. Septa have exsert teeth. Colonies have fleshy tissue over the skeleton, but this is not thick enough to mask underlying skeletal structures.

Colour: Mottled browns and greens, commonly with brown walls and green oral discs.

Habitat: Most reef environments.

Abundance: Uncommon.

Similar species: Acanthastrea bowerbanki , Acanthastrea echinata , Acanthastrea hillae
