Yes, another Pleurobranchus grandis. Beautiful animal.Comment from Scott Johnson on photo #16393
That certainly looks like Pleurobranchus grandis. I'm glad to see it at Kosrae. I have not yet found it in the Marshalls, but now I know I should look harder.Comment from Richard Willan on photo #8706

This individual displays an unusual colour pattern with a broad white marginal band. However the arrangement of the pustules on the mantle (one large pustule surrounded by a ring of 6 smaller pustules) and large exhalant ‘siphon’ at the rear when it is crawling actively are characteristic of Pleurobranchus grandis. Like most species of Pleurobranchus, it is a nocturnal species.Locality:
