Can anyone tell me what this is? Kinda looks like a tube worm.

There are a BUNCH of these white tube looking things.. My camera abilities or lack there of suck. I took a picture of the rock with the tubes on the rock though.. They really look like tube worms but I am not sure. There is something that comes out the end and retracts whenever something goes near it. I was just curious if anyone has an idea as too what it is. I am pretty sure the rock came from a fellow reefer when I went to the meet in rochester and those white things were always there but I just noticed today that things come out the end of them. I really think they are small feather dusters or something like that but I am so new to this I have no idea. Here is the rock the best pic I could get anyways..

Thanks for the help

Yep they are a small tube worm. I think they are in the Spirorbis family.
