在强烈的生存选择压力下，5亿年前，形成图像的视觉引发了一场持续的掠夺性军备竞赛。从那时起，尤其是在节肢动物中，捕食行为驱动了无数的眼睛适应，从而提高了视觉表现。在这篇综述中，我们提供了不同节肢动物捕食者如何改善关键视觉特征（例如视网膜的空间和时间分辨率）的示例。然后，我们描述了该组动物用来收集有关猎物的重要信息（例如距离、速度和大小）的形态、神经和行为策略。我们还强调了头部和身体跟踪运动对于帮助对潜在猎物进行分类的重要性，并简要提及了正在进行的关于目标拦截所需的感觉运动转换的工作。
Under strong selective pressure for survival, image-forming vision set off an ongoing predatory arms race 500 million years ago. Since then, and particularly so in the arthropods, predatory behavior has driven a myriad of eye adaptations that increase visual performance. In this review, we provide examples of how different arthropod predators have achieved improvements in key visual features such as spatial and temporal resolution of their retina. We then describe morphological, neural and behavioral strategies used by animals in this group to gather crucial information about the prey, such as its distance, velocity and size. We also highlight the importance of head and body tracking movements to aid in categorizing the potential prey, and briefly mention the ongoing work on the sensorimotor transformations necessary for target interception.
