Colour: Usually brown or muddy green but sometimes blue or purple.
Similar Species: Acropora spathulata and A. convexa. A. spathulata forms corymbose clumps with thicker branchlets. A. convexa has prominent radial corallites with prominent lower lips.
Habitat: Shallow water, usually reef flats, but also lagoons and upper reef slopes.
Abundance: Common.
Taxonomic Note: Part of a species complex also comprising A. convexa, A. spathulata and Acropora prostrata sensu Veron (2000a).
