Unknown Purple Tube Worm


I've been trying to figure out what exactly this is for years. I've taken it to my bio teacher and he couldn't ID it so he showed it to other bio majors and they couldn't figure it out either. So I'm thinking maybe it could be a new species? There are lots of them in the intertidal in Avalon bay year round. They seem to be some sort of keel worm (Pomatoceros), but all the pictures I see of them are white. None of them are purple like these. They all vary in length but are usually a few inches long.
