The Marine Species Identification Portal[3] recognizes three morphs : Cliopsis krohnii has a somewhat long, flabby, gelatinous body with a bluish aspect.

The posterior end of the foot has a folded tubercle that is not divided by longitudinal wrinkle in the middle.

The small lateral winglike flaps (parapodia) are used in a slow swimming mode.
