The common cuttlefish, Sepia officinalis (S. officinalis), has been admired and studied ever since the time of Aristotle, largely due to its ability to rapidly and actively display a remarkable repertoire of color, patterns and textures on its skin. The mechanisms underlying the rapid and varied colorations of S. officinalis have been studied closely since the late 1800s, and by 1940 it was well established that the active camouflage of cuttlefish was due to structures in their skin called chromatophores. Chromatophores are elastic pigment-containing sacs acted upon by a system of muscles directly innervated by nerve fibers whose cell bodies...
