Acropora subulata

(Dana, 1846)

Colonies are large circular tables or clumps often over 2 metres across, with a fine structure consisting of a network of horizontal branches and fine, evenly spaced branchlets. Small colonies are usually cushion-shaped. Axial corallites are tubular with rounded margins. Radial corallites are tubular and appressed.

Colour: Usually pale grey or brown, sometimes bright blue (which may photograph purple), purple or green. Corallite lips may be a contrasting colour.

Habitat: Shallow reef slopes with a high Acropora diversity, but protected from strong wave action.

Abundance: Common in shallow water.
