The generally accepted systematic name (in contrary to some others) of all mussels, clams and scallops - Bivalvia - the two-valve molluscs - refers to the most important character of all bivalves, that separates them from all other molluscs: The shell is separated into two pieces.See full list on anchorandhopesf.com Class Bivalvia ranges from Lower Cambrian to today, and peaked in the Cenozoic. Bivalve animals are typically encased in two shells—also called valves—hence the name bivalve. The shells have bilateral symmetry from top to bottom (the two shells look the same), rather than the side-to-side symmetry of the brachiopods (Figure 7.10).$\begingroup$ @ d_b, thanks for the comment. My confusion arises exactly from your point.
