Material examined

One specimen: KT (1) Sep. 2003.

Diagnosis

Tube missing.Opercular peduncle smooth, white, with marked constriction.Operculum funnel symmetric, with 46 radii with blunt tips, and concave inner surface, with numerous tiny conical tubercles ( Fig. 9A ). Collar with bayonet chaetae, with two blunt, short teeth, smooth distal blade. In adult forms, Serpula columbiana has an operculum with 55–160 radii ( Fig. 9B ) and a symmetric funnel ( Kupriyanova 1999).

Taxonomic remarks

The status of Serpula columbiana was resolved by Kupriyanova (1999). It is mainly a sublittoral species that is extremely unlikely to belong to the fouling fauna.

Ecology

Intertidal to 60 m. Under stones on the shore-line, in rock-pools ( Pixell 1912), and on bottoms with coralline sand and kelp, on shells, cobble and boulders ( Bastida-Zavala 2008).

Distribution

Northeastern Pacific, from Alaska to southern California (San Diego) ( Kupriyanova 1999; Bastida-Zavala 2008). In this work, only one specimen of Serpula columbiana was found on a fouling plate from Ketchikan Bay, Alaska ( Fig. 10 ).
