Tergipedid with a characteristic colour pattern. The body is translucent colourless with a scaterring of irregularly shapes bright yellow and milky blue patches. The head is translucent orange and the oral tntacles and smooth rhinophores are a very pale translucent orange, which becomes more intense towards the tip. There are a few scattered yellow patches on both rhinophores and oral tentacles. The cerata are translucent clear with small scattered yellow specks. Towards the tip there is a thin orange band, and below it, a broader milky blue band. The blue band is not always present. The digetsive gland is black, giving the cerata a granular black appearance. It grows to 15-20mm in length.
