Acropora granulosa

(Milne Edwards and Haime, 1860)

Colonies are semi-circular horizontal plates, usually less than one metre across. Plates are composed of regularly spaced horizontal branches with short inclined branchlets composed mostly of one or more axial and incipient axial corallites. Radial corallites are small and pocket-like.

Colour: Usually uniform cream, grey or pale blue (which may photograph purple), but may be other colours.

Habitat: Most reef environments, especially reef slopes protected from wave action.

Abundance: Common.
