鲸鱼可能会吃海洋塑料 因为声音回声模仿猎物 新杜克研究发现 Whales may eat ocean plastic due to sound echoes mimicking prey, a new Duke study finds.

杜克大学海洋实验室的一项研究发现,鲸鱼可能会摄入海洋塑料,因为碎片产生的回声在鲸鱼回声定位时模仿或超过自然猎物的音响信号。 A Duke University Marine Lab study finds whales may ingest ocean plastic because the debris produces echoes that mimic or exceed the acoustic signals of natural prey when hit by whale echolocation. 这种基于声音的欺骗,尤其是在深海,导致鲸鱼误用塑料作为食物,增加了健康风险。 This sound-based deception, particularly in deep waters, leads whales to mistake plastic for food, increasing health risks. 研究揭示了塑料污染伤害海洋哺乳动物的一个以前被忽视的机制,突出表明有必要减少海洋塑料并了解其声学影响。 The research reveals a previously overlooked mechanism by which plastic pollution harms marine mammals, highlighting the need to reduce ocean plastic and understand its acoustic impacts.
