Acropora microphthalma

(Verrill, 1869)


Oken, 1815

Characters: Colonies frequently exceed 2 metres across and may form extensive single species stands. Branching is arborescent, usually forming thickets. Branches are slender and straight. Sub-branches may occur at irregular intervals. Radial corallites are small, numerous, and of similar size.

Colour: Usually pale grey, sometimes pale brown or cream.

Similar Species: Acropora microphthalma is readily confused with other Acropora if these develop staghorn-like growth-forms. It is closest to A. copiosa and sturdy forms of A. parilis, the latter being distinguished by having widely spaced, elongate radial corallites. See also A. horrida, A. vaughani.

Habitat: Upper reef slopes, also turbid water and sandy lagoons.

Abundance: Common and may be a dominant species in shallow water.

Taxonomic Note: A species complex.
