Short description Morphology

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.

Biology     Glossary (e.g. epibenthic)

Lives in coarse sand, often near seagrass beds, in shallow subtidal depths (Ref. 344).

Life cycle and mating behavior 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.
