Species forms the largest colonies of all Acropora, with parallel, obliquely inclined, very thick, tapered branches. Corallites are tubular and irregular in length. Axial corallites are indistinct. Color can either be tan or pale brown with white axial corallites.

Biology     Glossary (e.g. epibenthic)

Maximum depth from Ref. 116012. Zooxanthellate (Ref. 116012). Found in shallow areas of high wave action, especially reef crests (Ref. 415) and submerged reef tops (Ref. 86439).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Hermaphroditic (Ref. 113712). Mature gametes are shed into the coelenteron and spawned through the mouth. Life cycle: The zygote develops into a planktonic planula larva. Metamorphosis begins with early morphogenesis of tentacles, septa and pharynx before larval settlement on the aboral end (Ref. 833).
