Montastrea magnistellata

Chevalier, 1971

Colonies are massive, hemispherical or flattened and may be over 2 metres across. Corallites are round and of variable size, those on convex surfaces being larger than those on concave surfaces. Corallites are shallow, approximately 6-13 millimetres diameter, with tightly compacted septa. Columellae are large and small paliform lobes are usually developed.

Colour: Commonly blue-grey.

Habitat: Protected reef slopes.

Abundance: Usually uncommon.

Similar species: Favia helianthoides
