Plerogyra sinuosa

(Dana, 1846)

Colonies are flabello-meandroid with valleys more or less connected by a light blistery coenosteum. Sometimes living parts of colonies are separated by dead basal parts. Vesicles are the size of grapes and usually have the shape of grapes but may be tubular, bifurcated or irregular, depending primarily on the state of inflation.

Colour: Cream or bluish-grey.

Habitat: Protected reef environments, especially, but not necessarily, in turbid water.

Abundance: Usually uncommon.

Similar species: Plerogyra discus

Taxonomic note: Taxonomic note: Colonies with very large (up to 10 mm wide) and exsert (over 10 mm high) septa were formerly considered to be a distinct species, Plerogyra eurysepta. Source reference: Veron (2000). Taxonomic reference: Veron and Pichon (1980). Additional identification guides: Randall and Myers (1983), Veron (1986), Sheppard and Sheppard (1991), Nishihira and Veron (1995).
