Concerning message #16287:

Bill,
Thank you for your reply. I ended up taking 7 photos of this specimen. All photos show similar proportions, with no indication of elongation or stretching. After looking closely at the photos, I would have to say that the body is opaque, even at the edges. There are signs of pustules that are slightly more apparent on the other photos.

Regards,
Mick

Dear Mick,
Thanks for another photo. I've had another think about it and still think Dendrodoris elongata is a possibility, but looking at the high rhinophore pockets, which hide most of the rhinophore stalk, made me wonder if it could possibly be a species of Aphelodoris? However there is no way of knowing unless you come across it again. If you do you can poke it a bit and see if it greatly elongates, but failing that try and turn it over and look at its head - not that easy underwater -. If the head has proper tentacles [see dorid head Fact Sheet] then it is not a Dendrodoris and so Aphelodoris becomes a real possibility. Unfortunately I haven't got a head of Dendrodoris in the Forum at present for you to compare, but its head merges with the foot and has no distinct tentacles.
Best wishes,
Bill Rudman
