						Shell ovate, much less elongate than Macrocallista nimbosa.  Surface highly glossy.  Sculpture of very fine growth lines under glossy layer.  Umbones small.  Lunule small.  Colour:  tan with irregular brown marks, sometimes arranged in radial bands.  Internally white.

					Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae				
			
			
				
					Members of the class Bivalvia are mostly gonochoric, some are protandric hermaphrodites.  Life cycle:  Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam.
