Amazing Nembrotha Kubaryana Sea Slugs
This relatively large species, sometimes growing more than 5 inches long, seems to range in color. Essentially black with green pustules, or green longitudinal ridges, there is a bright orange border to the foot and around the oral lappets. In some specimens the rhinophores and gills have orange markings but in others, these are green. In Western Australia the black background region can have pinkinsh orange spots or elongate marks.
