That's right it's a seccile snail; what you see coming out is the mucus net that it casts for food.

Idk what I was thinking! Vermatid snail is right. Spoinid is a worm, Ron says they aren't common and chaetopterid worms are what we have. These are the 2 tentacle creatures that grow out (help grow) heleopora blue ridge corals.
