Scientists have shown how animals see the world (7 photos + 1 video)
Scientists have developed technology that shows how animals see this world. Some of the shades that our smaller brothers see are hidden from human sight. 
Animals' eyes have different sets of color receptors - they allow each animal to see different spectra of light reflected from objects. And honey bees and some birds even have photoreceptors that can detect ultraviolet light beyond what humans can see. Researchers from the University of Sussex and the Hanley Color Laboratory at George Mason University created a video that showed how our little brothers perceive the world around them. 
When they created it, they focused on how birds and bees see the world - but argue that their tools can be used for any animal with a similar visual spectrum. In the video, they showed, for example, how a bird sees its surroundings - for them, the sky is a bright shade of purple. 
Bees can see the full human range of colors and ultraviolet light. They also use their color-sensing receptors to find flowers - to bees they always look very bright, as in the example below. In the video, the researcher applies sunscreen that would appear white to a human - but to the eyes of a bee, it looks like he is covering himself with yellow paint. 
Scientists also show how bees see the caterpillar of the Papilio polyxenes butterfly. To humans, it is a green caterpillar with black and yellow markings. But to a bee it looks like a riot of ultraviolet colors. The caterpillar's color appears very bright under ultraviolet light. 
To create such videos, scientists used a new method with cameras and software, with which they can now find out how any animal sees the world. When compared with laboratory methods, this method showed perceived colors with 92 percent accuracy. The researchers hope that these tools will help scientists understand how animals navigate the world around them. According to them, the method can also be used by filmmakers to better convey the colors seen by animals.
