The sacoglossan Elysia sp. 21 is not yet identified or still undescribed, I call it Elysia sp. 21 to
distinguish it from other species of Elysia, until I know its name.
Elysia sp. 21 is caracterized by its pale tan/pinkish background colour with minute green spots (most likely Zooxanthellae), by small pale rounded tubercles,
and by blue pigment on the tips of the rhinophores and on the tip of the 'tail'.
