Using Polarized Light Reflection and Perception as a Communication Channel
L. Dono and E. Thornquist
Do Cuttlefish Comminucate Using Polarized Light?
Cuttlefish have the ability to reflect polarized light using their arms and forehead, as well as the ability to perceive polarized light in their retinas (citation). There is also a little evidence that they have the ability to perceive light and possibly polarized light in the skin of their fins and the underside of the body (citation). Cuttlefish also have the ability to modify the pattern of the polarized light they reflect and whether they even reflect polarized light (citaion). It has also been observed that cuttlefish change the pattern of polarized light they reflect in response to signals sent to them by other cuttlefish (citation).
