The visual displays of animals and plants are often colourful, and colour vision allows
animals to respond to these signals as they forage for food, choose mates and so-forth. This …

Iridescence, the change in hue of a surface with varying observation angles, is used by
insects, birds, fish, and reptiles for species recognition and mate selection. We identified …
