Stimpsoni and M. ) kellettii are extant and are described below. , ranging from the east Atlantic to the east Pacific (Fig. 4). Conchological, anatomical, and biomolecular data all indicate Mercenaria to be more closely related to Anomalocardia and Lirophora than to Chione. Paleontological and conchological data indicate that Securella is closely related to Mercenaria. Anomalocardia was created simultaneously with Mercenaria, which has the longer paleontological record. This supports placing Anomalocardia, Lirophora and Securella as subgenera under the taxon Mercenaria.

Well known as a marine species, Mercenaria mercenaria is tolerant of low salinities (Wells, 1961). Hard clams were found living upstream in a North Carolina estuary, where salinity averaged 19%o (Wells, 1961), roughly half that of normal marine conditions. Failing to detect a low salinity death point for mature animals, Wells (1961) hypothesized that the animal must rely on its store of glycogen for anaerobic respiration when the valves are closed, the amount of stored glycogen determining how long the clam can survive under saline stressful conditions.
