Acropora echinata

(Dana, 1846)

Colonies are composed of prostrate, sometimes intertwined, bottlebrush branches. Secondary branchlets are fine and uniform. There is no distinction between axial and incipient axial corallites. Radial corallites are short and tubular or pocket shaped, indistinct or absent.

Colour: Usually cream or white, with blue or purple branchlet tips (which may photograph pink to red). Occasionally entirely blue.

Habitat: Protected reef environments with clear water and a high Acropora diversity.

Abundance: Usually uncommon but conspicuous.

Similar species: Acropora speciosa , Acropora turaki

Taxonomic note: Source reference: Veron (2000). Taxonomic references: Veron and Wallace (1984), Wallace (1999). Additional identification guides: Veron (1986), Nishihira and Veron (1995).
