Concerning message #10871:

Dear Bill,

I found this similar-looking nudi on Hexabranchus eggs, but in Nosy Be, Madagascar. Maybe it is the same?

Locality: Nosy Be, about 15 m, Madagascar, Indian Ocean, November 2006. Length: about 10 mm. Photographer: Ugo Gaggeri.

Thank you!

Ugo

Dear Ugo,

I am afraid the photos in Yves Coze's message are not clear enough to be sure of the animal's identity so I tentatively identified it as F. japonicus.  Your animal is definitely not that species and is one I am calling Favorinus cf mirabilis. We have a number of records of it feeding on Hexabranchus eggs. It seems a number of species of Favorinus feed on the eggs of Hexabranchus.

Best wishes,
Bill Rudman
