What the heck is this ?

Check this video I took of this wierd something. It's coming out from a shell, from the shell there is a tail made from the substrate. If you look at the video real closely you can see the clear tentacles coming out a sweeping around.

What can this be ???

It's a Chaetopterid or Spionid, a harmless tube worm.
