This spaghetti worm (possibly – Thelepus crispus) was noticed in shallow water with its pale tentacles spread out gathering food.  There is a wide variety of spaghetti worms along the Pacific Northwest coast and close examination by experts is required to differentiate one species from another.  A guess is that this one may be (Thelepus crispus) which apparently is a very common intertidal spaghetti worm.  It has a tube consisting of sand, small stones or mud that is often hidden with only the tentacles visible. This worm can spread out its tentacles to at least 12 inches (30 cm) across, with a range from Alaska to southern California.
