D. is correct. This animal was the subject of several days shooting. It was found in coral rubble that I collected at 30 m on the north shore of Moorea. It was taken to my lab in Berkeley where I photographed it. I must say it was the more remarkable octopus I have ever photographed. As for the species, I originally identified it as Abdopus abaculas. However, Crissy Huffard described a similar species from Tonga as Octopus gorgonas. A. abaculas is usually found shallow, O. gorgonas deeper, so we now believe that this is A. gorgoas. In the original description, it was in the genus Octopus, but it probably should be moved to Abdopus. Here are a couple of other shots of it - same animal.
