Why is movement perception important for animals finding food and avoiding predators?

Movement perception is a fundamental biological process that allows animals to orient themselves to physical movements, which is essential for survival. Because many animals rely on food sources that are themselves in motion, the ability to perceive and track these movements is critical for successful foraging.1

Regarding predator avoidance, the peripheral retina in many animals is highly sensitive to movement, which often serves as a signal of potential danger. This sensitivity triggers reflexive responses, such as turning the eyes toward the stimulus to recognize the threat. Once a threat is identified, animals utilize rapid avoidance behaviour, such as fleeing or escaping, to survive. These responses are often highly specialized; for example, some animals have evolved specific neural structures to initiate explosive escape movements that make it difficult for a predator to track or predict their path. Without these perceptual functions, an animal's ability to balance, move effectively, and evade harm would be severely compromised.231
