Abstract Sipuncula is a relatively species poor and generally rarely investigated phylum; nonetheless, it may play a considerable role in the ecosystem. During this study sipunculan species distribution patterns in four fjords of west Spitsbergen (Kongsfjorden, Hornsund, Isfjorden and van Mijenfjorden) were examined. Material was collected during ten cruises undertaken from 1997 to 2006. A total of 381 samples were taken at 132 stations located in the four fjords and, a total number of 920 sipunculans specimens were found in 114 of those samples. The highest sipunculan species richness was observed in Hornsund (six species), followed by Kongsfjorden and Isfjorden (Wve species in each fjord). Sipunculan fauna in all fjords was strongly dominated by GolWngia vulgaris (80 % of all sipunculan individuals in Kongsfjorden), and GolWngia margaritacea (84 % in van Mijenfjorden and 40 % in Hornsund) or Nepha-soma diaphanes (54 % in Isfjorden).
