The polychaeta is from the family of the Syllidae. You see here the proventricle (a barrel-shaped structure made of rings of muscle cells) and the proboscis of the anterior digestive tract. More interesting information about this organs: http://www.seaslugforum.net/message/17308 .

Lovely images. With those muscles I bet this would look spectacular under polarised light with a variable compensator.

In this case I took some Mytilus edulis mussels from the harbour. The Polychaeta very often are hiding between them.

Beautiful photo. What is your setup? I might have missed it if you posted on it in an earlier thread.

Very spectacular images. I have photographed this worm several times but never found out what it was! Thank you for posting this.

Finding worms in a sample is like finding gold. I have found quite a few, but only once have I found a duplicate, [one of the little ones with red spots] There must be hundreds of different kinds.
