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. Colour: upper valve bright, variable, ranging from brown to red to lavender rose to whitish with purplish or reddish mottlings, colour of lower valve much lighter, whitish with lighter markings.
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.

Preferred temperature
(Ref. 115969): 23.7 - 28, mean 26.9 (based on 680 cells).
Resilience
(Ref. 69278):
High, minimum population doubling time less than 15 months (K=1.88-3.06; tmax=2).
Prior r = 1.01, 95% CL = 0.66 - 1.51, Based on 1 data-limited stock assessment.
Climate Vulnerability
(Ref. 125649):
High vulnerability (63 of 100).
