Squid Skin Reveals Hidden Messages

Squid Skin Reveals Hidden Messages: "While the notion that a few animals produce polarization signals and use them in communication is not new, M�thger and Hanlon’s findings present the first anatomical evidence for a “hidden communication channel” that can remain masked by typical camouflage patterns. Their results suggest that it might be possible for squid to send concealed polarized signals to one another while staying camouflaged to fish or mammalian predators, most of which do not have polarization vision."
