I Spy with My Little Eye
MY EYE IS THE MOST SENSITIVE MOTION DETECTOR IN THE WORLD
A fascinating look at animal eyes
SPECIES: Eublepharis macularius
All it takes is a fraction of a second— a few millimeters, the mere twitch of a muscle— and the alarm starts to sound. The eyes of this creature are equipped with highly sensitive motion sensors. Where we’d see only dry desert sand, the eyes of this nocturnal hunter are able to perceive grains of sand being slightly lifted by a beetle digging under them. Exactly how they manage to accomplish this is a mystery. Researchers suspect a kind of ocular mutation known as marble eyes has produced a visual system in Eublepharis macularius that is markedly superior to even the high-tech cameras of today.
Animal eyes are among the greatest marvels in the natural world. They can spot a mouse from over a mile away, deploy a built- in night- vision camera, or provide a 360- degree panoramic view. But which animal is associated with which eye? id on the most fascinating visual apparatuses on the planet.*
