Eubranchus virginalis (Baba 1949
This is a great photo of this rather large Eubranchus. You can really see all the diagnostic characteristics. This species can reach 40 mm in length, although Marc's critter here was only a couple of millimeters long.
Note the characteristic cerata. They bare large pointed tubercles with black specks and a yellow-orange digestive glands. This critter resembles both some Doto's and Phyllodesmium if you don't look carefully. To distinguish it from a Doto - note, no rhinophoral sheaths. To distinguish it from a Phyllodesmium - it has sacks at the tips of the cerata for storing defensive nematocysts.
NSSI Second Edition gives the geographical range as Japan and Indonesia, Dr Marc adds too that here by adding the Philippine Archipelago.

Marc and Michelle Chamberlain reside in the Pacific Northwest in Seattle, Washington where they have lived for the last 15 years. They enjoy cold water diving and take advantage of their location to dive Puget Sound, Hood Canal, the San Juan Islands and the Olympic Peninsula all in Washington as well as multiple locations in British Columbia and southeast Alaska whenever possible. They also travel abroad (pre-pandemic), often combining land and water opportunities as in a trip to New Zealand, where they did extensive bird watching and hiking in addition to diving the Poor Knight's Islands (which I am going to put on my places to visit list).
Marc has a Nikon D500 in a Subal housing with 2 YS-D2 strobes and diffusers in addition to a variety of lenses.
Marc in his time in San Diego was SDUPS Photographer of the Year so many times that I lost count! In fact, Marc came to mind many summers ago during a trip on the Catalina Express from Dana Point. Due to a loading snafu, the bag
containing my camcorders was stowed down below and therefore unavailable during the hop over to Catalina. Well, you guessed it!, a Blue Whale breeched about 50 feet off the boat and hung around for about 10 minutes for
everyone onboard to get a shot. That is with the exception of yours truly! During the remainder of the voyage the only thought that came to mind was "if Marc has been onboard he would have been ready."
That folks is the difference between those who dream and those who actually do it!
