Characters: Colonies are composed of fused horizontal branches, forming small tables. Branchesusually have upturned ends which taper to a point. Corallites on horizontal branches are mostly immersed; those on upright branches are usually of two sizes, the larger being tubular, with sharp edges. Skeletons have a permanent dark colour. Colour: Usually bright or pale blue or brown. Similar species: Acropora hoeksemai, which forms colonies of similar shape but has larger branches and less irregular corallites. See also A. abrotanoides, which has larger branches and rasp-like radial corallites and A. valenciennesi, which has large proximal branches. Habitat: Turbid or clear water on upper or lower reef slopes. Abundance: Uncommon
