Similar Species: Acropora speciosa. See also A. subglabra, which has more irregular branches and shorter corallites and A. turaki, which has thick-walled axial corallites.

Habitat: Protected reef environments with clear water and a high Acropora diversity.

Abundance: Usually uncommon but conspicuous.
