Imaging technique: 

Close-up of the skin of an anesthetized male S. lessoniana showing differential chromatophore expansion and contraction due to the anesthesia. The characteristic white bars of mature males can be easily seen in this image. The left side of this image is of the mantle while the right side is of the fin. In fine detail, it can be seen how the white bars are sometimes surrounded by expanded dark chromatophores to highlight the bars.
