It turns out dragonflies have souped-up color vision that’s better than anything ever seen in the animal world. We humans have what’s known as tri-chromatic vision, which means we see colors as a combination of red, blue and green. This is thanks to three different types of light-sensitive proteins in our eyes, called opsins. We are not alone: di-, tri- and tetra-chromatic vision is de rigueur in the animal world, from mammals to birds and insects. But the dragonfly species has no fewer than 11, and some a whopping 30, different visual opsins. Amazing, right?
