230816 新研究:鳄鱼对人类幼崽哭声的反应惊人

▍原文

The cries of human, chimp and bonobo babies are so compelling that even other species recognize and react to them, including Nile crocodiles. However, to a croc, a human baby’s screams may sound less like a cry for help—and more like a dinner bell. According to a new study, crocodiles quickly investigate a human baby’s wails because the sounds of distress trigger a predatory response from the hungry reptiles.
