Like all species of Cerberilla, this species is adapted for living and burrowing in soft sediments and has a broad foot with long tentacular anterior foot corners and long oral tentacles. The smooth rhinophores are relatively long and slender

The body is translucent clear with reddish pink pigmentation on the head and base of rhinophores and oral tentacles. There is scattered white pigmentation on the tips of the oral tentacles, rhinophores, foot corners and cerata. The cerata are coloured by the large pinkish red digestive gland.  This species grows to approx 9 mm in length.
