Shrimp can see beyond the rainbow

"Mantis shrimps, dubbed "thumb splitters" by divers because of their vicious claws, have the most complex eyes in the animal kingdom, capable of seeing colors from the ultraviolet to the infrared, as well as detecting other subtle variations in light.

They view the world in up to 12 primary colors -- four times as many as humans -- and can measure six different kinds of light polarization, Swiss and Australian researchers reported."
