Acropora plumosa

Wallace and Wolstenholme, 1998

Colonies form horizontal tables of spectacular dimensions. Some colonies are irregularly shaped, mostly either due to breakage of the original colony or to the formation of irregular clusters of plates. Plates are side or centrally attached and are composed of radiating, irregularly dividing, interlinked main branches re-linked occasionally by sub-branches. Axial corallites are small and tubular. Radial corallites are widely spaced, tubular, and strongly appressed.

Colour: Brown with pale branch tips.

Habitat: Sheltered reef slopes.

Abundance: Uncommon, but very conspicuous.

Similar species: Acropora clathrata , Acropora pharaonis

Taxonomic note: Source reference: Veron (2000). Taxonomic references: Wallace and Wolstenholme (1998), Wallace (1999).
