Two well-known and long-standing global vectors for the dispersal of marine species are international shipping and international trade in edible seafood. Far less well known is the impact of these interoceanic movements on the biogeography of species boring into the calcareous substrata (barnacles and tubeworms in vessel biofouling and mollusc shells, such as oysters, in the aquaculture trade) that often characterize these vectors. We review shell-boring polychaete worms in the genus Dipolydora from the Temperate Northern Pacific, seeking to elucidate the possible consequences of anthropogenic dispersal on selected species. An emphasis is placed on D. giardi (Mesnil in Cr Hebd Séances Acad Sci Paris 117:643–645, 1893) which was originally described from northern France and later reported worldwide. This species is an opportunistic borer of shells of various molluscs and other calcareous biogenic substrata. The Bayesian inference analysis of sequence data of four gene fragments (2468 bp in total) of the mitochondrial 16S rDNA, nuclear 18S, 28S rDNA, and Histone 3 shows that individuals from northern and Mediterranean France, Argentina, Australia, Italy, Japan, South Africa, South Korea, and the Pacific coasts of Canada and the USA are genetically similar and can be considered conspecific. Polydora trilobata Radashevsky, 1993 described from the Sea of Japan, Russia, is synonymized with D. giardi. We suggest that international shipping and the movement of commercial oysters, previously overlooked as key processes in creating its global distribution, may have dispersed D. giardi to far-flung corners of the world. An identification key to nine shell-boring Dipolydora species from the Temperate Northern Pacific is provided
