Dear Dave and Bill,
I have a question about the Caribbean Favorinus. It seems that the form of the rhinophore of this individual isn't symmetrical. Is it common that the rhinophore of the right and the left is different? I think that the form of the rhinophore is important in the description of sea slugs?

Best Regards,

Dear Jun,
The shape of the rhinophores is important in characterising species of aeolid - that is why I was not certain of Anne DuPont's recent photos of Dondice occidentalis until I could see the shape clearly. Normally the rhinophores are identical in shape, so I suspect in this Favorinus that the right rhinophore has been damaged and has regrown. The number of 'swellings' on the rhinophore has been used to distinguish species of Favorinus, but as I discuss on the Fact Sheet, in this species it seems the number of 'swellings' is related to the size of the animal.
Best wishes,
Bill Rudman
