Dragon Flies are 95% successful at capturing their prey.
Their Eyes Are Incredibly AdvancedMost insects have multifaceted eyes—house flies, for example, have about 6,000 eye facets that give them a panoramic view of their surroundings. It’s the reason their eyes look like honeycombs up close. But with 30,000 individual facets, dragonflies blow them—and every other insect—completely out of the water. Each facet, or ommatidia, creates its own image, and the dragonfly brain has eight pairs of descending visual neurons to compile those thousands of images into one picture.And it gets even crazier; dragonflies have visual senses that would be considered superpowers by any human standards. Human eyes have three opsins—proteins that sense light—giving us a color range of red, green, and blue (one for each opsin). Dragonfly eyes can have four or five opsins, allowing them to perceive the normal color spectrum, along with UV light and the plane of light polarization (the effect you get with polarized sunglasses). This is believed to help them navigate and reduce the sun’s glare on a body of water.
