无尾类两栖动物的复杂的声行为对其繁殖与物种的识别具有重要的作用,而有尾类除了少数种类可以发出微弱的"吱吱"声或吠声外,在过去一直被认为是基本不发声的.但是,最近的基于解剖学的证据的研究显示隐腮鲵科(Cryptobranchidae)可能是一个例外.为了检验这一假说,作者对实验室严格控制的条件下的4只中国大鲵(Andrias davidianus)进行了观察.观察结果不仅表明动物在水下发声,同时也观察到了与之相关联的行为.作者对进一步在野生条件下开展研究提出了建议.

Anuran amphibians exhibit complex vocal behavior, which is an important mechanism in breeding and species identification. In the past it has been assumed that caudate amphibians are generally silent, with the exception of a few which have been shown to emit faint squeaks and barks. More recent researches have indicated that Cryptobranchid ae may be the exception, as having a true voice based on anatomical evidence. To test this hypothesis we studied 4 specimens of the giant Chinese Salamanders, Andrias davidianus, under controlled laboratory conditions. These observations appear to verify both the presence of underwater vocalization and some behaviors associated with it. It is suggested further research under field conditions is warranted.
