Recently, researchers in the US have put together a new camera with the ability to view the world like animals do.

• The specialised cells that respond to the light, called photoreceptors, are unique to each animal. For example, while human eyes can detect only wavelengths of light in the visible range (between 380 and 700 nanometres (nm)), honey bees and many birds can also perceive ultraviolet light (10-400 nm).
• Animals use colours to intimidate their predators, entice mates or conceal themselves. Detecting variations in colours is thus essential to an animal’s survival.
• Animals have evolved to develop highly sensitive photoreceptors that can detect light of ultraviolet and infrared wavelengths.
