black worm with grey feeding apparatus - Musandam Oman - what is it?

[simplycatherine]

Hi, just seen a long worm type thing, black with grey feeding apparatus in a Y shape at one end, drapes around rocks and coral in the Musandam Peninsular in Oman. I have a photo, but can't work out how to attach it! Any help would be gratefully received! `Would love to know what this critter is!

Here is a Thysanozoon nigropapillosum http://reefguide.org/pix/thysanozoonnigropapillosum2.jpg

A picture will really help, as I do not even know if this worm ventures this far west.
