ANSWER!
If
you guessed Northern Feather Duster Worm, you're right!
Eudistylia vancouveri
Annelida Phylum
Name:
Northern feather duster worm
Other names: Plume worm, parchment
tube worm
Description: Polychaete worms inhabiting
leathery or parchment appearing tubes and extending to form plumes with
feather duster appearance. This species often forms large aggregations
but may also be found as solitary individuals.
Color: Plume has alternating bands
of maroon and dark green
Range: Alaska to California
Size: Tubes reach a length of 24 inches
and diameter of ½ inch. The plume is up to 2.4 inches in diameter.
Hangouts/Habitat: Found on floats,
pilings, and rocky areas.
Depth: Intertidal to 100 feet
Behavior: Has light sensing structures
and if a shadow falls across it, the plume will zip back into its tube
in the blink of an eye.
ID clues: There are other similar
appearing sabellid tubeworms with parchment like tubes and feathery plumes
so look for tubes with a diameter slightly larger than that of a pencil
and the maroon/dark green banding on the plumes.
