Click here to read the article ...A rare frog that lives in rushing streams and waterfalls of east-central China is able to make itself heard above the roar of flowing water by communicating ultrasonically, says new research funded in part by the National Institute on Deafness and Other Communication Disorders (NIDCD), one of the National Institutes of Health. According to the study, which appears in the March 16, 2006, issue of [EM]Nature[/EM], attributes that enable the frog to hear ultrasounds are made possible by the presence of an ear canal, which most other frogs don’t have. The research may provide a clue into why humans and other animals also have ear canals: to hear high-frequency sounds.
