Acropora tenuis

(Dana, 1846)


Oken, 1815

Characters: Colonies are corymbose clumps, usually with neat evenly spaced delicate branchlets, but branchlets may be irregular and prostrate. Axial corallites are distinct and tubular. Radial corallites are arranged in a neat rosette and have slightly flaring lips.

Colour: Yellow, cream, green or blue. Colours may be bright with distinctively coloured corallite lips.

Similar Species: Acropora eurystoma. Acropora vermiculata, which forms branches and has short axial corallites. See also A. selago, which has scale-like radial corallites not arranged in a rosette. Corymbose A. pulchra has smaller, scale-like radial corallites.

Habitat: Upper reef slopes.

Abundance: Common in the western Pacific and Red Sea, uncommon elsewhere.

Taxonomic Note: Similarities with Acropora eurystoma require further study.
