This allows you to better understand how different fish, birds, and animals see the world.

Scientists have already used various computer and television screens to test the sight characteristics of animals, as well as their perception of the surrounding world. Usually, wildlife representatives viewed visual images on screens, while researchers observed the animals' reactions to these images. But none of these displays could test the particular vision of fish, for example.

The point is that fish are able to see the world thanks to ultraviolet rays. This ability, in addition to fish, is found in some insects, crustaceans, reptiles, birds, and even mammals. To deepen the extraordinary vision of all these particular faunas, an ultraviolet screen has been created.

The development of scientists displays ultraviolet rays as well as visible light. “Human televisions typically use three colors to create images: red, green, and blue. But the screens we designed generate five colors, including purple and ultraviolet,   says study author Samuel Powell.

The animal TV screen is quite small, measuring only 4 × 5 cm and its resolution is  8 × 12 pixels. It shows moving dots and simple geometric shapes. Thus, scientists have already discovered that clownfish of the species  Amphiprion ocellaris can respond to pure ultraviolet blue, gray, and ultraviolet colors. Now they are trying to find out how it helps fish in life.
