No clue what this thing is

[BristleWormHater]

This thing looks like an empty feather duster tube but I was watching it and two tendrils shot out and threw some waste out then retracted. I am absolutely positive it is not a feather duster, thoughts?

sorry, but we need a better pic

maybe a video of the tendrils would help someone smarter than me identify!

I’ll try my best but it’s a hard angle

I’m pretty sure it’s a spoinid worm are they harmful?

Got the best video I finally caught it after sitting here for 20 minutes. Worm video

@ISpeakForTheSeas any ideas?

Bump

Veremetid snail? Maybe

It’s interesting to watch it clean out its waste then dip back in its tube.

Does anything in this video look familiar? Have you seen a mucus web?

I think that's it but the tube seems different.

I think its building its web I'm starting to see it. It's such a shame they are toxic, otherwise I would love to have it. I guess super glue it is then

 

[BristleWormHater]

Update: I haven't glued it yet I'm still not sure If it is a vermetid, the web I thought I saw was a cat hair. I'm in no rush because I have no corals or fish. Its tendrils seem a little long to be a vermetid, and when it goes back into the tube I can't see any foot like the vermetids have. @ISpeakForTheSeas

Knew I'd missed a thread earlier- yeah, with the two long tendrils sticking out and the tube being in the rocks, it's most likely a Spionid worm. The coral-boring varieties are often harmful, but most kinds are only a problem if their numbers grow too large.

I'm thinking its a spionid worm, but I was doing more digging and looks a lot like a chaetopterid/parchment worm, thoughts?

Chaetopterid worm - they're very similar to Spionid worms, but they tend to prefer burrowing in the sand instead of in the rocks, and they reportedly tend to have longer palps.

That said, I say probably because to make a proper ID involves removing the worm from its tube and getting pics of the body out of the tube, which just isn't feasible.

Generally, these aren't a problem unless their numbers start getting out of hand.
