This Bearded Fireworm (Hermodice carunculata) was prowling around on a stand of black coral when I spotted him off Jackson Wall.  He could not possibly have been more exposed, yet these little guys have no fear.  The poisonous bristles break off easily whenever a predator molests them, and I understand the resulting rash can be quite painful.  Fortunately, this isn't one lesson I've had to learn by hard experience.
