Macro photo of live skin of Loligo plei showing different colored chromatophores in different states of expansion and contraction. This view shows how stripes are produced running from upper right to lower left. There are large, expanded chromatophores lying in the stripe that will largely conceal the stripe. Contraction of these chromatophores would expose the clear bands or stripes to view.
