It could be a variety of fireworm (hermodice carunculata is the one most often meant). The fact it's out of water has made it contract. Leslie H in Invertebrates could tell you accurately, but under the rule "things travel on what they eat", and the fact that this blunt head may have a mouth that does more than suck, as bristleworms must do, it remains suspicious. If your rock (or the speciman rock) came from the Atlantic/Caribbean, more suspect. I don't think I'd put it back in. I'd be very interested to hear what Leslie H has to say.
