Does Anyone know what this is?

It's been growing in the Montipora for quite a while ... and generally growing to Scale. I assume it's some type of worm ... the shell is hard ... there is always a long filament coming out of it, which I give the turkey baster treatment, although I 've yet to see the filament causing any harm. It's at the size (0.5 to 0.75 inches across) where it retracts further back in the shell, but I 've never seen it extend out of the shell.
