Sabellaria spinulosa?

[goosey]

I found this this morning, it was a couple of cm's long and alive. I couldn't see a face.
I picked it up and was trying to decide if it should be in the sea or not . Anyway when I put it down again (hoping it was a sand dweller) it had left yellow stains on my hands, wetties wouldn't get it off, I was worried it was poisoness or I would have a reaction and incase in inadvertantly rubbed my mouth or eyes, I have scrubbed my hands since I have been home and the stain is still there.

Do you think it could be a Sabellaria spinulosa?

Intriging I don't think its Sabellaria spinulosa like its relative the Honeycomb Worm Sabellaria alveolata they are colonial reef builders
My first impressions are its a holothurian - a sea cucumber albeit a small one.
They will sometimes exude the contents of their guts if handled. The only holothurians I've dealt with were from the Crozet Plateau in the Southern Indian Ocean so I'm not familiar with North Sea Species.
The Marine Species Identification Portal has a key - if you're brave
Marine Species Identification Portal : Macrobenthos of the North Sea - Echinodermata : Key

Possibly something like Pseudothyone raphanus given the size and thinner looking tail end.

I'd be glad to hear of any other ID suggestions myself

I haven't managed to get very far with the key .
I am still not getting away from Scalibregma when I am searching images but could Scalibregma inflatum be a possibility?

I have put it on waarneming.nl but unless a real expert in the field is passing I don't really expect an answer.

Have you tried looking under Holothurians? I keep coming back to it being one of the Synaptidae, possibly Lapidoplax ?sp, with the 'tentacles' abraded away - but I could be so very wrong

It looks like you two are thinking along the same lines with Holothurian, which must be a good sign that it is a small cucumber of some type.
Thanks for all the thinking, but you can carry on a bit longer if you want .
