Nembrotha sp. (undescribed)

Members of the Nembrothinae lack velar and extrabranchial as well as other lateral processes, and the oral tentacles are usually relatively small compared to those of other polycerids. Species of the genus Nembrotha Bergh 1877, are specialized predators on tunicates. They fall into two natural groups, one including species with raised tubercles or lines and the other with a white background color and longitudinal brown to red lines. This undescribed member obviously belongs to the latter.

The body is white with a few black lines dorsally and yellow pigment, which extends on to the gill and more posteriorly. It is subtly similar to Nembrotha megalocera and N. purpureolineata but the black lines and purple pigmentation on the base of the gill, as well as some internal differences distinguish them.

Marc,and Michelle Chamberlain
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!
