We saw this at various sites in the Tulamben area. It appeared to be eating opisthobranch eggs deposited on a hydroid. Although we have seen this as a color form of Favorinus mirabilis, it seems the much larger colored cerata tips and lack of white spots are likely to separate them. It has been suggested that Favorinus pacificus may be the correct designation. Baba's original description does not mention any white spotting on the cerata and body, but of the cerata it does state that the cerata are "dark yellow almost to the tip which terminates in white cap, with a purple marking below." This is not like the colored tip of our specimens and in fact, sounds more like the coloration of F. mirabilis. So the precise identification of these animals remains in doubt.
The animals below were discovered only after the fact while examining a photo of Chromodoris colemani, so the quality of the zoomed-in image is not too good. The smaller white eolid to the left is probably a young specimen.
