It is one of many unrelated edible bivalves that in the United States are frequently referred to simply as clams, as in the expression "clam digging".

Confusingly, the "ocean quahog" is a different species, Arctica islandica, which, although superficially similar in shape, is in a different family of bivalves: it is rounder than the hard clam, usually has black periostracum, and there is no pallial sinus in the interior of the shell.
