Concerning message #22062:
Hi Bill,
Gary's photo of Pleurobranchus caledonicus looks a lot like what is on the Forum as Berthella cf africana.

I am glad someone is awake! I am not sure how I missed that but you are absolutely right. I have moved the messages concerning Berthella cf africana to the P. caledonicus page. Clearly Pleurobranchus caledonicus has a wide distribution in the tropical and subtropical Pacific. As I discuss on the Fact Sheet, your use of the genus Berthella is most probably correct but I would like some more anatomical information from Pacific animals before changing its name. Can you recall if the brown mark in the middle of the mantle is a pigment mark or an actual hole in the skin?
This of course brings us back to Berthella africana. Is it just an Atlantic form? of the same species, or perhaps a geographic subspecies?
Best wishes,
Bill Rudman
