Description Edmundsella dushia is a flabellinid with opaque white pigment covering most of the body. The translucent body is visible through areas at the bases of the tentacles and rhinophores, behind the eyes and bases of the cerata. The rhinophores and oral tentacles are translucent at the base and covered with opaque white pigment in the outer two thirds. Mature animals reach 15 mm in length or up to 20 mm.Welch J. J. (2010).
