Interesting worm from FL live rock

[pmemmer]

Wondering if anyone can ID this guy... came in on some uncured Florida live rock. This is the best pic I've been able to get. His mouth looks like something akin to a feather duster, but his body is more bristle-worm like (though not quite so bristly). Any ideas? Some folks on a different forum have suggested maybe peanut worm, but he looks nothing like any peanut worm I've ever seen in another picture.

Got a picture of his mouth... towards the top of the rocks, and a little bit to the left of center.

Interesting worm from FL live rock

Because of mouth structure it Looks more like a sea cucumber to me....maybe look up polyplectana sp. or opheodesoma sp. or again synapta sp.

Hope this helps

I'd say probably a sea cucumber, a filter-feeder. Not certain what kind, but he's probably harmless.
