Identification
This marine worm can be identified by its banded green and maroon or purple plumes (radioles), which get to 5 cm in diameter. The radioles are only occasionally branched. It has a long light grey tube with a parchment-like texture, into which it can retract its plume when disturbed. The tube gets to approximately 1 cm in diameter and 60 cm tall.
Habitat & Range
The northern feather duster worm aggregates in large clusters on docks, pilings, and rocks, from the intertidal to a depth of 30 m. Its range extends from Alaska to central California.

Similar Species Two other Eudistylia species exist on the BC coast. Neither has the distinct green and red or purple banding of the northern feather duster worm. The polymorph feather-duster (E. polymorpha) is variable in colour, and may be maroon with lighter coloured bands. The split-branch feather-duster (Schizobranchia insignis) is uniform but variable in colour, and has dichotomously-branched plumes iNaturalist https://www.inaturalist.org/taxa/84864-Eudistylia-vancouveri |
