Thanks Erwin,
The pink compound ascidian, in the enlarged part of your photo alongside, makes me wonder if perhaps N. milleri gets some of its colour from its food. This of course is all a bit of a guess because we don't even know if it eats compound ascidians. But as the pink spots seem to be where the excretory glands in the skin are, and as the chemicals in them seem to be associated with their food, it seems worth thinking about,
Best wishes,
Bill Rudman
