Here's Janolus eximius which I found yesterday at the Poor Knights.
Locality: Poor Knights Islands, 10m, nthn New Zealand, Pacific Ocean, 10 June 2006, Rocky reef. Length: 12mm. Photographer: Ian Skipworth.
To my knowledge, this is not a commonly seen species and this is the first time I've seen it.
It was moving quickly and crossed several substrates as I watched it.

Richard Willan, who wrote the Fact Sheet for this species, mentions that "Janolus eximius has never been found off its food – the large, clumping bryozoan Orthoscuticella aff. margaritacea" so your observations show that it can sometimes be a little adventurous. I suspect the reddish bushy growth, in the left of the photo alongside, is the bryozoan Richard is talking of.
Like Tritonia flemingi [message #16856] this is a valuable addition to our knowledge of another rarely found species.
