TED-Ed: Which animal has the best eyesight? | Thomas W. Cronin

The video explores the diverse visual capabilities of animals, highlighting those with exceptional night vision, sharpness, color perception, and motion detection. Colossal squids and reindeer excel in low-light conditions, while birds of prey have the sharpest vision. Mantis shrimp and butterflies have complex color vision systems, though their practical use remains a mystery. Insects are adept at detecting motion due to their rapid photoreceptor response. The video concludes that no single animal excels in all aspects of vision, as each has evolved specialized adaptations.
