Abstract

The morphology of the mussel Crenomytilus grayanus from different biotopes manifesting the adaptation of this mollusk to attached life on the bottom surface was studied. It was established that colonization of rocky coastal areas with active hydrodynamics by mussels is related to retardation of linear growth rates, the formation of convex shells, and vigorous development of retractor muscles of the foot and byssus. An environment protected from the effect of surfs on silted bottoms facilitated the fast growth of mussels, which resulted in the formation of an elegant flat shell. In that biotope mussels are specified by a rather poor development of the muscles responsible for its attachment to the substrate.
