Characters: Colonies are composed of fused horizontal branches, forming small tables. Branches usually 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.
