Larvae of the eastern oyster (Crassostrea virginica) develop a foot just before settling to the bottom.
Clams, such as the hard clam/northern quahog (Mercenaria mercenaria), are bivalves, meaning that they have shells consisting of two halves, or valves.
The other bivalve that we grow, the bay scallop (Argopecten irradians), has some distinct differences from hard clams and oysters.
