Characters: Colonies are tables, usually side-attached, generally with horizontal radiating anastomosing branches becoming highly fused at the centre of large colonies. Branchlets may have upturned ends; these are seldom vertical. Axial corallites are small. Radial corallites are of mixed sizes and crowded, with sharp-edged nariform openings.
Colour: Brown, grey or green, often with pale margins.
Similar Species: Acropora tutuilensis, which has larger, thicker branches without upturned ends. See also A. clathrata which has finer and more crowded branches.
Habitat: Shallow margins of fringing reefs.
Abundance: Common.
