Lomanotus marmoratus

Dan Bolt Apologies for the poor photos, but I'm in two minds about these fellows. Image no.1 was about 40mm but no.2 and no.3 are about 20mm. Are these all juvenile Lomanotus marmoratus ? Thank you for any help :-)

Sarah Bowen Lomanotus marmoratus? (on a roll now!)

Arne Kuilman Never seen anything like it before. Cool.

Bernard Picton Ah, this is the/a spotty form, Sarah. I think there are two things in Lomanotus marmoratus, but I need more observations. One of them swims very readily whilst the other is reluctant to swim, and a different pattern of markings on it.

Sarah Bowen Must look more closely in future!

David Kipling Is this annoyingly difficult-to-photograph critter Lomanotus marmoratus? Near Skomer, 16m depth, cobble-sediment seabed, on Nemertesia. I know distinguishing them from L. genei is non-trivial.

Marco Faasse In my opinion this is Lomanotus marmoratus. Aegires punctilucens does not have a thin tip to the bulbous end of the papillae.

David Kipling Bernard comments on there being occasional colourless versions of L. genei that can look like L. marmoratus ... I'm not quite sure what to look for to tell them apart excluding colour.

Marco Faasse It must be late. I read Aegires, which you didn't write, David Kipling. I think I have never seen L. genei with such bulbous cerata tips.

Terry Griffiths I have the coloured version of L.genei and the plain white variation, i think it's L.marmoratus i have also have the marbled variation of it to, nice find tho.

David Kipling It took a while to convince myself it was a nudi. It was only when I zoomed in and saw the rhinophore sheaths that I knew, at which point it got a lot more attention!

Kirstie Harris Found this chap on a site in Pembrokeshire over the weekend. Can anyone tell me what it is? Thanks.

João Pedro Silva Really need some more detail, but I think there are only 3 possibilities * in your area: Doto fragilis, Doto pinnatifida and Lomanotus marmoratus. My guess is D. pinnatifida. * feeding on Nemertesia antennina

Kirstie Harris Thanks! My husband took some photos too, so he might have a better one. If he has, I'll ask him to post it.

Terry Griffiths I would go for D. pinnatifida

Klas Malmberg Aquatilis D. pinnatifida - black tipped tubercles both on cerata and on the sides of the body

João Pedro Silva After downloading and enhancing the image, no doubt on my first guess.

Kirstie Harris Thanks for your help, everyone.
