This species is compared with Doris obvelata by the authors, a synonym of Cadlina laevis. Cadlina glabra is described as coloured white, with tentacles and gills yellow. No tubercles visible on the mantle even with magnification, but like Doris obvelataintense sulfur-yellow spots are scattered along the edges. The mantle does not extend far beyond the foot. The shape is an elongated oval. The liver shines through brown. Length 10mm. Radulaformula40.1.40 x 70 rows of teeth; their form very similar to Doris obvelata. It might be considered to be merely a deepwatervariant of Doris obvelata; however, the complete lack of tubercles and the much greater number of teeth seem to justify its separation as a distinct species.
