Cephalopods including squid, octopus and cuttlefish are known for a stunning array of visual displays. These marine creatures possess pigment cells called chromatophores surrounded by muscles that expand and contract, allowing for a wide variety of colorful patterns. While researchers understood these abilities, a question remained regarding just how deep-sea cephalopods might make these displays visible in their dark, deep environment.
