NewsPhys.orgHunting behavior drives the evolution of spider eye arrangements, study finds
Vision shapes how many animals find food, avoid danger and navigate their world. In animals with two eyes, eye placement is often linked to lifestyle: predators such as lions tend to have forward-facing eyes that help them judge distance, while prey animals such as deer typically have eyes positioned on the sides of the head, providing a wider view of their surroundings. Eye placement can reveal much about ecology, yet most of what we know comes from animals with only two eyes. Spiders present a fascinating challenge to this picture. Most species possess eight eyes, arranged in remarkably diverse configurations, raising the question of how these patterns relate to hunting strategy.
