Hi Bill,

I would like your confirmation on the identification of this nudibranch. I've identified it as Diaphorodoris luteocincta but I'm not sure.

Dear David,
Although this animal has similarities to Diaphorodoris luteocincta and also to some white chromodorids, I am pretty sure this is Chromodoris purpurea. On the whole it lacks the purplish colouration of the mantle and body which gives this species its name, but there is still a distinct purplish tinge on the gills and the rhinophores and a distinct opaque white tip to each rhinophore and gill, whichbas you will see on other photos on the Forum, are characteristic of C. purpurea. A look at its anatomy would be needed to confirm this identification, but C. purpurea has been reported from the Azores. You don't give any indication of its size. Maybe smaller animals lack the purplish tinge of older animals?
Best wishes,
Bill Rudman
