Phys.org / Cuttlefish use polarized light to create a dramatic mating display invisible to humans

Many organisms leverage showy colors for attracting mates. Because color is a property of light (determined by its wavelength), it is easy for humans to see how these colors are used in animal courting rituals. Less obvious ...
