Cemented Sandmason Worm
Neosabellaria cementarium
Typical size: ¾” diameter (plume)
ID: Hard tube coated with sandy. Fine lavender plume.
Comments: I have only noted this inconspicuous tube worm while diving the San Juan Islands. This worm uses the surrounding sand when constructing its tube for camoflage and fortification. Photo taken at Peapod Rocks in Roasrio Strait.

Fringed Tube Worm
Dodecaceria fewkesi
Typical size: .33” diameter (plume)
ID: Hard white tube. Yellowish-brown plumes with black, usually on the tips. Grows in colonies
Comments: I note this tube worm quite often in the San Juans when diving rocky reefs. The purple encrustation that co-habitates with this worms is corraline algea.

Northern Feather Duster Worm
Eudistylia vancouveri
Typical size: 1-2” diameter (plume)
ID: Distinctive black and maroon colored plume. Hard, brown tube.
Comments: Feather duster tube worms are common throughout the Northwest waters. This tube worm often attaches itself to the underside of docks. Amazing colonies of this worm are readily found clinging to may of the buoy anchor lines in Edmonds Underwater Park. This worm retracts its flambuoyant plumage into its tough tube when approached.

Feather Duster Worm
Typical size: 1-2"diameter (plume)
ID: Colored plume - typically solid orange, yellow, or white. Plume "feathers" do not branch.
Comments: I typically find this beautiful feather duster worm in isolation throughout Washington waters. Another species of feather duster worm is very similar in appearance, but tends to grow in colonies and has plume feathers that branch. Photo taken at Three Tree Point in Puget Sound.

Slime Tube Worm
Myxicola infundibulum
Typical size: 1” diameter (plume)
ID: Distinctive plume varies in color from light to dark purple. Retracts quickly when approached in a gelatinous looking tube.
Comments: The unusual slime tube worm is readily found on soft substrates. I usually note this worm living in colonies with 5-20 others slime tube worms. Less often I find lone specimens, as pictured here. The slime tube worm retracts very quickly into a semi-transparent gelantenous-like tube when approached.

Split-Branch Feather Duster Worm
Schizobranchia insignis
Typical size: 2” diameter (plume)
ID: Radial plume. Color varies highly, but is usually (but not always) solid. Distinctive branching in plumes.
Comments: This beautiful feather duster is another common inhabitant of northwest waters. I usually find it growing in dense colonies. Many of the ropes anchoring marker buoys at Edmonds Underwater Park (which is where this photo was taken) are infested with these thriving colonies of these worms.

Twin-eyed Feather Duster Worm
Bispira sp.
Typical size: 2” diameter (plume)
ID: Radial plume in red and white. Retracts quickly when approached in a gelatinous looking tube. Usually isolated.
Comments: This worm is a fairly common inhabitant of sandy substrates. Although it is referred to as a twin-eyed feather duster won, it's radial plume reportedly contains up to a thousand tiny eyes that can sense shadows. Photograph taken at KVI Tower Reef in central Puget Sound.

Calcareous Tube Worm
Serpula columbiana
Typical size: ¾” diameter (plume)
ID: White tube, although often encrusted. Red plume with white and yellow bands.
Comments: This colorful worm is common throughout Washington waters. It quickly retracts into its tube anytime a diver aproaches, leaving the diver to wonder what all the curved, white empty tunes are that litter the bottom.

White-Crowned Calcareous Tubeworm
Protula pacifica
Typical size: 1” diameter (plume)
ID: Hard white tube. Two elegant white plumes which spiral outwards from the body.
Comments: This worm is extremely sensitive and usually retracts quickly when approached. This worm is relatively common throughout Washington waters. Photographed at Three Tree Point in central Puget Sound.

Bristleworm
Nephtyidae sp.
Typical size: 1" length
ID: Highly varied.
Comments: This entry captures a large family of bristleworms which come in various shapes and sizes. I rarely note this worm pictured, which belongs to a family of worms known as "goddess worms". Exact species ID requires disection - and who wants to cut up this elegant creature? Thanks to Dr. Sheila Byers for help in identication. Photographed at Three Tree Point

Speghetti Worm
Thelepus crispus
Typical size: variable
ID: Long, thin tentacle like strand emanating from a common source .
Comments: The body of this worm is hidden in the sediment; only the tentacles are visible to a passing diver. The worms tentacles create a web-like appearance and lie in wait for unsuspecting prey. Photographed in Barkley Sound, British Columbia.

Joint Three Section Tubeworm
Spiochaetopterus costarum
Typical size: 1-3” height above substrate (tube only)
ID: Tough chitonous tube with two long palps which can be extended from the tube.
Comments: I find these small and inconspicuous tube worms almost everywhere I can find a sand substrate, epsecially at shallower depths. This little worm is very quick to retracts when approached. Photographed near Race Rocks, British Columbia.
