New research shows how bats use echolocation unexpectedly to detect silent and stationary prey in darkness. Bats may use acoustic search images to identify potential prey when prey-generated noises, visual and olfactory cues are absent.
新研究表明,蝙蝠如何出人意料地利用回声定位在黑暗中探测到无声和静止的猎物。当猎物发出的声音、视觉和嗅觉线索不存在时,蝙蝠可能会使用声学搜索图像来识别潜在的猎物。
