Short description Morphology

Shell oval, heavy, very thick. Hinge with lateral teeth transversally striated. Pallial sinus reduced. Umbones anterior, pointing inward and in anterior direction. Periostracum strong and smooth. Colour: externally dirt white, internally glossy white with slight blue-grey tinge; periostracum grey-brown (Ref. 271).

Biology     Glossary (e.g. epibenthic)

Maximum depth range from Ref. 104365.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Life cycle: Embryos develop into free-swimming trocophore larvae, succeeded by the bivalve veliger, resembling a miniature clam (Ref. 833). Spawning is continuous throughout the year (Ref. 104339).
