Nudibranchs are fun to photograph, and you have some beauties. A couple of tips . . . As already stated, shoot toward the rhinopores and get them in focus; they're the "eyes" of the nudi. Try to find them in "action" poses, where it's clear they are moving, if you can. Get closer! You can crop the shots you have to make the slug more of a focus, but even better is to get right down on the animal and fill the raster with it. Use depth of field to your advantage -- bokeh works really well with slugs.
Take a look at some of Kenneth Kopp's shots (Mo2vation on SB). I model my nudi photography after Ken's.
