Acropora inermis

(Brook, 1891)


Oken, 1815

Characters: Colonies are usually open branched, becoming bushy on upper reef slopes and in shallow lagoons. Main branches may have compact branchlets giving colonies a bushy appearance. Corallites are widely spaced and vary greatly in size, the largest being appressed and tubular. The coenosteum is fine, giving branches a smooth appearance.

Colour: Brown, with pale branch tips.

Similar Species: Acropora proximalis. See also A. vaughani, which has more uniform, less appressed radial corallites and greater development of incipient axial corallites.

Habitat: Turbid water around fringing reefs.

Abundance: Uncommon.

Taxonomic Note: Acropora inermis (Brook, 1891) is a synonym of Acropora horrida in agreement with Wallace (1999) and Wallace, Done and Muir (2012). Acropora inermis sensu Veron (2000a) remains under review.
