Concerning message #16131:

Dear Bill,
If I didn't know where the animal on Discodoris evelinae Fact sheet (lower photo) is from, I would without much thinking say it's Dendrodoris grandiflora from the Adriatic Sea!
I would like to hear opinion from other colleagues from the Mediterranean on this.
Best regards,
aj

Dear Andrej,
That photo came from a message from Ross Gundersen [#11112] and as I commented there, his description of it breaking off its mantle skirt made me think of Discodoris. I also thought I could see papillae all over the mantle which would be most unlike Dendrodoris.  However on reflection perhaps his upper photo is a Dendrodoris. Angel Valdes [message #5289] said that D. krebsii  was the only species of Dendrodoris like this in the west Atlantic, but the striations around the mantle edge certainly look like D. grandiflora.

I am puzzled by Ross's mention of mantle autotomy, I have a feeling some Dendrodoris break off part of their mantle during preservation but I can't find a reference. This animal certainly looks like a Discodoris in colour, so if it is really a Dendrodoris, perhaps Ross confused the two. Like you, I would welcome some comments from Angel and other experts on the Atlantic fauna.
Best wishes,
Bill Rudman
