It is somewhat hard to imagine that different organisms actually see in different ways than we do. We are very limited in our perception of other species’ perceptions. Cats, bees, and whales, for example, all see things in ways we don’t. But there is one organism that sees in the widest range, and in the deepest colours, beyond even our wildest imaginings, and that is the somewhat humble dragonfly.
It comes down a relatively simple equation in theory: genes and their expressed products crafted by natural selection resulting in the most amazing range of light-sensitive molecules in the animal kingdom. Of course, it is much more complex in reality.
