Abstract: | The morphology of the shell and byssus threads was studied in two closely related mussel species Crenomytilus grayanus and Mytilus coruscus. The two species differ significantly from each other in the shell shape and in the degrees of development and deformation of byssus threads. These differences, in turn, determine (either directly or indirectly) the differences in strength of the byssal attachment and are discussed in terms of their functional morphology with respect to the spatial distribution of the mussels in marine coastal zones. |
