We saw one of these crawling exposed on the dark sandy slope east of the Liberty wreck in Tulamben Bay in November 2015. The animal was probably in the 80-100mm range.
The next two shots show small solid brown oval disks on the head and at the base of some cerata. These appear to be acoel flatworms that are sometimes found living on hard corals such as Pleurogyra sinuosa and occasionally on soft corals such as Sarcophyton, the prey of this nudibranch. It seems likely the nudibranch ate the soft coral colony, causing the flatworms to transfer over to hitch a ride while the nudibranch hunted for its next meal.
