Stigzelius, J.; Laine, A.; Rissanen, J.; Andersin, A.-B.; Ilus, E. (1997). The introduction of Marenzelleria viridis (Polychaeta, Spionidae) into the Gulf of Finland and the Gulf of Bothnia (northern Baltic Sea). Ann. Zool. Fenn. 34: 205–212
The spionid polychaete Marenzelleria viridis (Verrill 1873) was for the first time observed in the Finnish coastal waters at the entrance of the Gulf of Finland in 1990. During 1990—1993 M. viridis expanded its distribution into the eastern parts of the Gulf of Finland and into the southern part of the Gulf of Bothnia. Its introduction into the Baltic Sea has probably occurred through ship transport, as all the first findings are connected to harbour areas. Although the abundance and biomass of M. viridis is comparatively low the species seems to have become a permanent member of the macrozoobenthos in the northern Baltic.
