Characters: Colonies are usually open branched, becoming bushy on upper reef slopes and in shallow lagoons. Main branches may have compact branchlets giving colonies a bushy appearance. Incipient axial corallites may be abundant. Radial corallites are widely spaced and vary in length. The coenosteum is fine, giving branches a smooth appearance, visible underwater.
Colour: Uniform blue (which may photograph pink), cream or pale brown.
Similar Species: Acropora horrida. See also A. austera, which may have a similar colony shape but has larger, more compact radial corallites. See also A. tortuosa and A. rufus.
