The large, contiguous eyes are situated between the long, simple rhinophores. Many inflated cerata are arranged in about 10 dense rows, and the pointed tail protrudes behind the cerata. The anterior corners of the foot are produced into long tentacles. The colour of the head and the tail is white, and the rhinophores are black or dark blue. A distinctive dark mark is located behind the eyes; the anterior part of the mark is somewhat star-shaped and its posterior part is elongated. The anterior margin of the foot and the area dorsal to the mouth are darkly pigmented. The cerata are green with white tips and are spotted with small, black chromatophores.
