Researchers have built a television display to find out how clownfish see the world.

Scientists have known for a long time that many animals see colours differently from humans. In animal vision studies, televisions and computer monitors are often used to display images and colours. But the problem is, screens for human use generally use three colours – red, green and blue – to create images, and these cannot test ultraviolet (UV) vision.
 

Ultraviolet light has wavelengths measuring between 10nm and 400nm. Visible light, which humans can see, measures from 400 to 700nm.

Now, however, scientists at the University of Queensland in Australia, have developed a new display that also includes violet and ultraviolet, which will allow them to test the visual capabilities of animals that can see into the ultraviolet spectrum. And clownfish (Amphiprion ocellaris) were the first animals to get a front-row seat.
