新的研究发现 鲸鱼们降低交配声 以躲避猎食者 Baleen whales lower their mating song pitch to evade orca predators, new study finds.

最近的研究表明, 雄性白鲸调整他们的交配歌曲 以避免美洲豹捕食者。 Recent research shows that male baleen whales adjust their mating songs to avoid orca predators. 当遇到虎鲸的风险很高时,这些鲸鱼在较低频率唱歌,以避免被发现,这有助于它们生存。 When the risk of encountering orcas is high, these whales sing at lower frequencies to avoid detection, which helps them survive. Baleen鲸鱼通过从水中过滤浮游生物来觅食,改变它们的行为,在寻找伴侣与避免掠夺之间取得平衡。 Baleen whales, which feed by filtering plankton from water, modify their behavior to balance finding a mate with avoiding predation.
