This infraclass includes the cockles, Venus clams,[1] the freshwater mussels, brooch clams, as well as Heterodonta and Archiheterodonta.[2]
Description
These bivalves are distinguished by having the two halves of the shell equally sized (i.e, they are equivalved) and having a few cardinal teeth separated from a number of long lateral teeth. Their shells lack a nacreous layer, and the gills are lamellibranch in form. Most species have a siphon.[3]
