Patrik Good My favourite at the moment (because I didn't expect to find these refreshing colours in that shape): Cadlinella ornatissima (Risbec, 1928).
Matthias Wildermuth Nice one.where did u spot it?
Patrik Good It is a nice one, isn't it. Found it on Old Woman Island - last week, 27/11/2011, about 25mm. Reminded me of a sorbet ice cream on that beautiful day where we were steaming from spotting so many different nudis.
Matthias Wildermuth Saw it only once south of sydney. A beautiful critter
João Pedro Silva That one was small. But the larger ones are not big either, only 12mm.
Patrik Good Nice, reminds me a bit of the Cadlinella ornatissima we are finding here.
João Pedro Silva Just because of the colour of this individual (this one was feeding on eggs of Lepadogaster lepadogaster) because anatomically they're very distinct (this is an aeolid). This shot may help to clarify:
