Abstract

Thanks to a sampling of juvenile oysters with different growth rates (slow, medium and fast), a subtle biometrical study of their shell evolution is described distinguishing the two valves. We conclude that all the phenomenaare dominated by the early establishment of a directional asymmetry, whichrapidly becomes so large that we should consider dissymmetry. The dearest relationship is revealed to be that between the weakness of the growth rateand the degree of the relative dissymetry between the weights of the valves. This result is to be compared with the highly debated relationship between the asymmetry and the growth rate. The existence and interpretation of both of these phenomena have led to many publications. (C) 2000 Academie dessciences/Editions scientifiques et medicales Elsevier SAS.
