Goniopora stokesi

Milne Edwards and Haime, 1851

Colonies are free-living or attached, hemispherical or (rarely) have short thick columns. Calices have high walls which have a ragged appearance. Columellae are broad and irregular. Small satellite colonies often occur embedded in the living tissue of parent colonies. Polyps are of mixed sizes, the larger being elongate.

Colour: Pale brown or green, usually with green tentacle tips.

Habitat: Usually found free-living, on soft substrates.

Abundance: Usually uncommon, but conspicuous.

Similar species: Goniopora lobata

Taxonomic note: Source reference: Veron (2000). Taxonomic reference: Veron and Pichon (1982). Additional identification guides: Veron (1986), Sheppard and Sheppard (1991), Nishihira and Veron (1995).
