Characters: Colonies are submassive or are short thick columns. Columellae are prominent, dome-shaped, and commonly divided into six parts, each part having a deltaic pattern of four septa. Polyps have large oral cones.
Colour: Pale or dark brown or green. Oral cones are usually white or blue (which may photograph pink).
Similar species: Goniopora pendulus and G. columna, which also have large oral cones. The former has bigger polyps with much longer tentacles, the latter has a more columnar growth-form.
Habitat: May form large single species stands in turbid water.
