Description
''Acropora pharaonis'' is found in colonies of flat table-like structures, or simply in structures of clumped vertical or horizontal twisted branches. Colonies can have heights over and they are orderly and symmetrical. Branchlets are of lengths up to with diameters of and branchlets can reach long and have diameters. Brown-grey in colour with branches having pale tips, the branches become thinner towards the ends and contain many small branchlets, which contain axial, incipient axial, and radial corallites. The axial corallites, located on the ends of the branchlets, are small with outer diameters of between 1.5 and 2.6mm and inner diameters of 0.6-1.5mm. Incipient axial corallites frequently occur on the branchlets, giving them a spikey surface. The radial corallites are located in close proximity and contain small nose-shaped openings and randomly placed spinules. This species looks similar to '' Acropora clathrata'', ''Distribution
