Acropora globiceps

(Dana, 1846)

Colonies are digitate and usually small. The size and appearance of branches depends on degree of exposure to wave action, but are always short and closely compacted. Colonies exposed to strong wave action have pyramid-shaped branchlets. Corallites are irregular in size, those on colonies on reef slopes are tubular, those on reef flat colonies are more immersed. Axial corallites are small and sometimes indistinguishable. Radial corallites are irregular in size, and are sometimes arranged in rows down the sides of branches.

Colour: Uniform blue (which may photograph purple) or cream.

Habitat: Upper reef slopes and reef flats.

Abundance: Common.

Similar species: Acropora gemmifera , Acropora monticulosa , Acropora retusa , Acropora secale

Taxonomic note: Source reference: Veron (2000). Taxonomic reference: Wallace (1999). Additional identification guide: Randall and Myers (1983, as Acropora wardii).
