Acropora abrotanoides

(Lamarck, 1816)

Colonies are clumps of prostrate branches with fused central branches and upwardly projecting peripheral branches. Branches may be conical to elongate, with or without pointed ends. Branches may have one to several axial corallites. Radial corallites are elongate.

Colour: Deep pinkish-brown or greenish-grey.

Habitat: Shallow reef environments, especially reef margins exposed to strong wave action.

Abundance: Sometimes common.

Similar species: Acropora irregularis

Taxonomic note: Taxonomic note: The names Acropora abrotanoides and A. danai have previously been used interchangeably due to loss and subsequent recovery of the type specimen of the former species. Acropora abrotanoides was originally described from the ‘Indian Ocean’ and is the senior synonym. Acropora danai was originally described from Tahiti. Source reference: Veron (2000). Taxonomic references: Wallace (1978), Veron and Wallace (1984, as Acropora danai), Wallace (1999). Additional identification guides: Veron (1986), Nishihira and Veron (1995) (both as A. danai).
