Cerberilla affinis Bergh, 1888 (revisited)

This photo caused some confusion at first maybe thinking it was Cerberilla sp. 2 in Indo-Pacific Nudibranchs. At closer look it is actually a very light colored C. affinis. What makes the ID for sure are the cerata with black and yellow sub-apical bands, the black mask and the blue oral tentacles. C. affinis has several look-alikes, most notably C. annulata and some light specimens of C. ambonensis.

This species is rather large, reaching 90 mm and has a very wide Indo-Pacific distribution. It is active nocturnally feeding on tube anemones.
