In the specimens with distinct dorsal spots, there is never any pigmentation on the tail. A distinct white line is present on the external edge of the foot, although this could be broken or punctuated. No specimens found with blackish non-transparent pigmentation on the body, nor any homogeneously orange specimens. Absence of light pinkish subapical ring on cerata. Small white pigment dots of various density can be present on the cerata. The upper part of the rhinophores is commonly covered with white relatively dense dots with small insertions of yellowish brown pigment in some specimens, without the formation of ring-shaped colouration. The oral tentacles are similarly coloured.

Adriatic specimens differ from the Atlantic ones in smaller size and different colouration. There is often a light blue pigmentation that covers cerata, rhinophores and oral tentacles, partially or completely, often the whole animal has a bluish appearance.
