Help. Identify Worms

Got my live rock today. Thought it was a bristle worm but upon looking at the identify FAQ's I couldnt find a picture of any. the only thing i can think of is peanut worm? it has this body that looks like a purple-ish pinkish earthworm with a mushroom shaped head and teeth ( ithink) pic included ill post more pics If this one goes smooth.
