| The Archer fish (Toxotes jaculatrix) demonstrates a remarkable ability to accurately capture aerial prey despite distortions caused by light refraction at the air-water interface. This study applies Snell’s law to quantify the discrepancy between the apparent and actual positions of prey, revealing how the fish instinctively adjust their aiming strategy. Observations show that Archer fish maintain high targeting accuracy across varying prey heights and distances, employing rapid adjustments in shooting angle and water jet dynamics. These behaviors reflect sophisticated sensory-motor integration, enabling precise compensation for optical distortions. The findings provide insight into the adaptive evolution of predatory strategies in aquatic environments and suggest potential applications in bio-inspired optical and robotic targeting systems. |
