DescriptionThe body is translucent white in colour with opaque white pigment on the tips of the oral tentacles and in a broken line along the centre of the back which becomes continuous on the long tail. The cerata are numerous and arranged in clusters along the sides and back of the body, almost hiding the white centreline. They are filled with red or orange-red granular digestive gland. The cerata have a thin, sometimes incomplete, ring of white pigment below the tip. Typically about 15mm-25mm in length, but well-fed individuals may be larger.
