I don't think it's a bobbit. Bobbits are extremely fast and cautious- poking one would cause it to retreat, fast. It could be some other kind of eunicid worm, which may be totally harmless. but I'd expect most eunicids to retreat a lot faster.
It doesn't look particularly healthy. Seems to be moving oddly. Removing it is probably a good idea in case it's dying, but try not to kill it- it may be something that somebody would want. Put it in a container of some water and get a really nice close-up pic.
In case you were wondering, the little white tendrils in the sand around it look to be from spaghetti worms. Harmless detritivores the majority of the time, though they can annoy corals if they happen to reach their feelers across the corals on a regular basis.
