Characters: Colonies have many shapes varying from upright bushes to thick plates. There is a continuous range of shape and size between axial and radial corallites; both may be tubular to nearly spherical, with very thick walls. Tubular axial corallites often have no radial corallites on one side and pocket-like radial corallites on the other. All corallites are smooth and rounded.
Colour: Usually pale blue (which may photograph pink) or brown. Axial corallites are usually whitish.
Similar Species: Acropora rosaria and A. appressa. Acropora caroliniana and A. granulosa have more elongate axial corallites. See also A. maryae.
Habitat: Upper reef slopes but occurs in a wide range of environments.
Abundance: Common in the central Indo-Pacific.
