What Is This Weird Looking Thing???

I came home this afternoon and noticed a milky colored translucent tube coming out of the base of my live rock. It expanded out almost like what an elephants truck would do and picked at debris on the sand and then retracted back into the live rock. I wasn't able to get a pick of it but it only made me think of the arm(whatever the proper terminalogy is) of an anenome as a way to describe it. Any thoughts??
