The Eye of the Dragonfly (Part 2)
Dragonflies have the largest compound eyes of any insect, each containing up to 30,000 facets. Each facet points in a slightly different direction and creates its own image, and the dragonfly’s brain compiles these thousands of images into one picture. This eye structure enables dragonflies to be extremely sensitive to motion. Because a dragonfly’s eyes wrap around its head, it can see in all directions at the same time.
