This tentative classification follows an unpublished list by W.E. Schevill and E.M. Mitchell currently under review. The scientific names are followed by the name of the individual who named the species and the year of naming, and then by the common name most often used in the western North Atlantic.[6] It may be noted that some of the authors are in parentheses. This indicates that though the species name has remained the same since the date of naming the species has since been assigned to another genus. Because the species are not arranged in taxonomic order in this field guide, the page of the synoptic account of each is provided in the column to the right.

[6] Most common names are based on some characteristic of the species (e.g., spotted dolphin, striped dolphin, rough-toothed dolphin); others are the names of authors of the species (e.g., True's beaked whale) or of habitats or macrohabitats which they inhabit (e.g., North Sea beaked whale and harbor porpoise); the origins of some common names, however, are less obvious (e.g., dense-beaked whale), and of less use in field references.
