Shrimps see beyond the rainbow
Date:5/13/2008

We doubt that circular polarisation is used exclusively as a secret shrimp sex signal! It makes more sense that mantis shrimp evolved both circular and linear polarisation receptors to work together so they can detect tiniest changes in any polarisation.

Prof. White notes, Some of the animals they like to eat are transparent, and quite hard to see in sea-water - except they're packed full of polarising sugars - I suspect they light up like Christmas trees as far as these shrimp are concerned. And of course, Dr Kleinlogel concludes, they can still flirt with each other using fancy polarisation cues!
