Chris Ross has been posting some nice Nudibranch images. His "Blue Dragon" brought memories of this shot from the Philippines where this common nudibranch can also be found.
It eats hydroids that have nematocysts (stingers) and zooxanthellae (algae that grows in tissue, like most corals) and incorporates them into its' own tissue. So this nudi can sting and go long periods without eating, the algae in its tissue supplying sugar from photosynthesis. The algae also imparts the brown/green color.
This Nudibranch can be quite long by macro standards, 2-3 inches, and I found that full body shots were tough. I have not seen focus stacked shots, probably because this slug is always moving.

Very nice Stan, like details captured and DOF covers everything well. You are right about this nudi being long; the shot I posted, that specimen was well over 3 inches long.
