中文摘要：

选用同域分布于湍流生境的凹耳臭蛙（Odorranatormota）、大绿臭蛙（Odorranagraminea）、武夷湍蛙（Amolopswuyiensis）和花臭蛙（Odorranaschmackeri）的口腔底壁皮肤为研究对象．并以非湍流生境分布的黑斑侧褶蛙（Pdophylax nigromaculatus）为对照。通过比较解剖和组织切片对比几种蛙类皮肤结构发现，超声蛙类凹耳臭蛙的皮肤比其他物种更薄更松弛、皮肤横切面粘液腺较小且数量较少。这些特征可能有利于凹耳臭蛙口腔产生较大沉降．从而为其声带的高频振动提供结构基础。

英文摘要：

The mouth floor＇s skin of concave-eared frog （Odorrana tormota） together with its sympatric three frogs Odorrana graminea, Amolops wuyiensis, and Odorrana schmackeri were compared in anatomy and histology, with Pelophylax nigromaculatus as contast. O. tormota has looser and thinner skin where the mucus glands are smaller and less than others frogs in this study. These characters possibly help O. tormota to extend its mouth floor deeply, and then serve to supply high sublaryngeal pressure which make the vocal cords vibrate at a high frequency.
