The initial draft of this list was based, in part, on information in American Seashells, second edition (Abbott,
1974) and on lists of mollusks prepared by the Council
of Systematic Malacologists and the American Malacological
Union for the American Fisheries Society (Turgeon et al., 1988; Turgeon et al., 1998).The Florida list was created by selecting from those larger lists the estuarine and marine species known from eastern North America and then by reducing that set of names, first by deleting the names of species not known from Florida and then by deleting the names of several hundred species known only from intermediate and deepwater regions of the continental shelf off Florida
