thank you so much for the interest and many replies I received. After having sent out the second image the general opinion is that the specimen most is probably a Nereid. I like to thank you especially in the name of the ROV team here supporting me (I am on an oil rig working with the ROV team - biological sampling is not in their job description). They are very impressed with the fact that their work (i.e., taking the footage for me) has raised such an interest.
We will try to find the specimen later on today and collect it - but since I am working with a working class ROV which is not equipped for scientific work our home made collection contraption might not work so well. And of course finding a specific worm on the seabed might be the proverbial search for the needle in the haystack.... But we will try.
