Crab spider vision improves their prey capture despite low visual system investment
尽管视觉系统投资较低,但蟹蛛的视力仍可提高其猎物捕获摘要蟹蛛(Thomisidae)是众所周知的捕食者,通常伏击花朵和其他植物上的猎物。这种捕食方式表明,尽管蟹蛛的眼睛相对较小,但视觉在捕获猎物方面具有潜在的好处。然而,目前缺乏关于视觉对蟹蛛捕获猎物成功率影响的行为证据。为了解决这一知识差距,我们评估了与果蝇作为猎物共养的失明和未失明蟹蛛(Sidymella rubrosignata)的捕食行为。结果表明,缺乏视觉线索严重阻碍了猎物捕获的成功。我们使用微计算 X 射线断层扫描将这一发现置于背景中,以定量比较红纹蜘蛛与其他具有已知狩猎策略(视觉和非视觉)的蜘蛛物种的视觉光学和中枢神经系统。我们发
