Description
Color: Uniform pale grey, cream or brown.

Colonies are columnar or laminar, or both. Columns divide but do not anastomose. Corallites are thick-walled. Columellae are short or absent.The species has distinctive colonies which are basically massive, but with numerous club shaped or cylindrical, stout columns. These columns divide, and are usually oval in cross-section, and then remain separate from adjacent columns.

The reproductive regime of Pavona clavus perhaps is based on slow sexual regeneration augmented by asexual reproduction.
