Acropora dendrum

(Bassett-Smith, 1890)


Oken, 1815

Characters: Colonies are usually 0.5-1 metre across and are corymbose plates with widely spaced, slightly tapering branchlets. Axial corallites are small. Radial corallites are immersed or nearly so, giving branchlets a smooth appearance.

Colour: Pale brown or cream.

Similar Species: Acropora microclados, which has tubular radial corallites and incipient axial corallites. May be mistaken for fish-grazed or diseased colonies of other corymbose species where axial corallites are mostly immersed.

Habitat: Occurs only on upper reef slopes where Acropora diversity is high.

Abundance: Rare.
