Short description Morphology

Shell outline almost circular, valves very inflated, wing-like projections relatively poorly developed. Surface sculpture of about 20 ribs, smooth square in cross-section. Hinge straight.

Biology     Glossary (e.g. epibenthic)

Life span: 18 to 24 months (Ref. 350). Lives in beds in shallow to moderately deep water, usually on (or buried in) sandy bottoms (Ref. 344). Also in seagrass and algae beds (Ref. 106861).

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

Spawning and recruitment occur throughout the year, with peaks in late autumn and spring.
