Notodoris sp. 2
Locality: Sodwana Bay, 22 metres, South Africa, Indian, Oct 2007, coral reef. Length: 50 mm. Photographer: Colin Ogden.
This is possibly an 'albino' form of one of the known species, but if so the general shape is more similar to N. gardineri and N. serenae than to N. citrina. As to the black in the rhinophores, it seems from photos on the Forum that the juveniles of all species, other than N. serenae, can have rhinophores with black pigmentation.
At present I think we should distinguish it as Notodoris sp. 2.Authorship details
