Chameleons’ Eyes Can’t Look In Two Directions At Once, Research Shows

Well known among nature’s best tricksters for their ability to change color to fit their background, chameleons have yet another talent up their lizardly sleeves – eyes that swivel around and appear to be looking in two directions at once.

To Professors Ehud Rivlin of the Technion-Israel Institute of Technology, and Prof. Gadi Katzir of the University of Haifa, this seemed like an intriguing research question. They went about answering that question by getting chameleons to play a computer game especially designed to potentially frustrate the creatures, yet possibly solve the riddle of whether chameleons really enjoy ‘eye independence.’

When the researchers showed chameleons a double image of a tiny insect moving opposite directions across a computer screen, the reptiles focused first on one image with one eye while the other eye “wandered.” Suddenly, both eyes locked on one image a nanosecond before the reptile cocked its dart-like, sticky tongue and fired at-will.
