Acropora fastigata

Nemenzo, 1967


Oken, 1815

Characters: Colonies are small clumps of a few very elongate branches. Each branch consists of a single upright axial corallite which has a thick base and is tapered. The distal tips of axial corallites are smooth and devoid of radial corallites. Below the tip, small radial corallites moderately crowded. Larger colonies usually have numerous incipient axial corallites.

Colour: Tan, or blue (photographing pink) usually with pale axial corallites.

Similar Species: None. Acropora multiacuta has smaller axial corallites without numerous basal radial corallites.

Habitat: Shallow reef environments.

Abundance: Rare.

Taxonomic Note: Considered to be 'unresolved' by Wallace (1999), who noted similarities with the Acropora humilis group. As illustrated here the species is distinct in both the field and collections.
