Pseudopolydora paucibranchiata
Taxonomic Group: Annelids-Polychaetes
Common name: SPIONID WORM


Pseudopolydora paucibranchiata is a tube-building spionid polychaete. It was described from Japan and its native range extends from Hong Kong to the southern Kuril Islands. Introduced populations are known from the Northeast Pacific (Baja California to Washington), Southwest Pacific (Australia and New Zealand), and Northeast Atlantic (Norway to the Mediterranean). It is commonly found in shallow intertidal mudflats, but is also known from harbor pilings and oyster beds. Possible vectors include ballast water, hull fouling, and Pacific Oyster (Crassostrea gigas) transplants. This species may be a complex of many species, but molecular studies are needed to untangle the taxonomy, biogeography, and invasion history of this group.
