cuttlefish use polarised light, which humans are unable to see, to communicate with each other and to distinguish objects under the water, according to a new Australian study.
Previous research has shown that fish and some reptiles can use wavelengths of the invisible UV spectrum to communicate with each other, but it was unknown how much other marine creatures used light outside the visible spectrum.
"The accuracy with which cuttlefish can see polarised light is much greater than we thought and that’s lending strong evidence that there’s this sort of language ofpolarisation out there that we previously didn’t appreciate,” says co-author Professor Justin Marshall from The University of Queensland in Brisbane.
