Acropora divaricata

(Dana, 1846)

Colonies have an exceptionally wide range of growth-forms ranging from flattened plates to cushions. Branches may be flattened or tapered. Axial corallites are often devoid of radial corallites on their upper surface. Radial corallites are all similar and are usually aligned along branches. They change along the branch from immersed to tubular and appressed.

Colour: Usually dark brown or greenish brown, sometimes with light brown or blue branch tips or dark blue with whitish tips.

Habitat: Upper reef slopes, lagoons and fringing reefs.

Abundance: Common, may be a dominant species.

Similar species: Acropora natalensis , Acropora stoddarti

Taxonomic note: Taxonomic note: This species is divisible into several smaller semi-distinct taxonomic units. Source reference: Veron (2000). Taxonomic references: Veron and Wallace (1984), Wallace (1999). Additional identification guides: Veron (1986), Nishihira and Veron (1995).
