The sacoglossan Elysia sp. 17 is not yet identified or still undescribed, I call it Elysia sp. 17 to
distinguish it from other species of Elysia, until I know its name.
Elysia sp. 17 is caracterized by its mottled brownish appearance, and by its opaque white spots or spicules - impossible to tell from this
blurry picture. The rhinophores seem to have blueish tips.
