Characters: Colonies are clumps of prostrate branches with fused central branches and usually upwardly-projecting peripheral branches. Branches may be conical to elongate, with or without pointed ends. Branches may have one to several axial corallites. Radial corallites are elongate. Colonies from exposed habitats are distinctive.
Colour: Deep pinkish-brown or greenish-grey.
Similar Species: Acropora robusta, which has similar corallites, but is readily distinguished by the presence of thick encrusting bases and is also more colourful. See also A. sukarnoi and A. intermedia.
Habitat: Shallow reef environments, especially reef margins exposed to strong wave action.
Abundance: Sometimes common.
