Dear Bill,

Dear Carlo,
I am not an expert on the Atlantic fauna so perhaps one of our European or North American friends can help. It looks like a Spurilla or Berghia. Ernst Marcus (1955) describes some specimens from Sao Sebastiao Island, Sao Paulo State which he identifies as Spurilla neapolitana (Chiaje) var braziliana MacFarland, 1909. He describes the colour as "orange with a brown liver. On the back is a pattern of light spots"

Your photo could possibly be of this species which he later (Marcus & Marcus, 1977) considered simply to be a colour form of Spurilla neapolitana.
