Dana, 1846

Colonies are massive, columnar, laminar, branching or encrusting and are usually less than one metre across. They are commonly mixtures of these growth-forms. Corallites are separated into groups by ridges.

Colour: Usually brown or blue.

Habitat: Shallow reef environments.

Abundance: Common in the western Indian Ocean.

Similar species: Porites rus
