Nembrotha kubaryana, also known as the variable neon slug, is a species of colorful sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Polyceridae. [3]
This animal can reach a total length of more than 120 mm. It is a large dark-bodied nudibranch which may have green stripes running down the length of the body or have green raised spots. The margin of the foot and head is a vivid red-orange. The rhinophores and gills may be red or green. Nembrotha kubaryana is easily confused with a similar species, Nembrotha cristata although the latter has no red orange border on its foot.
