Mice are an increasingly popular animal model for understanding vision in health and disease, but we know little about how they naturally use vision to guide behavior. Instinctive avoidance behaviors—freeze and flight—provide natural behaviors, but what visual stimuli cause mice to choose one behavior over another? De Franceschi et al. show that mice are likely to freeze at the sight of small slow-moving shapes and flee from fast approaching ones.
