| 摘 要： | 无尾两栖类呼吸系统发生于第14～第16时期，鳃弓形成后，渐次形成外鳃、鳃盖、内鳃，在内鳃发生的同时，外鳃鳃丝退化，最终消失，鳃弓上被内鳃取代无尾两栖类呼吸系统发生的时期、发展的速度、发展形式以及外鳃的形态，都不相同，这主要由于种间差异所造成．

| Abstract: | Anuran amphibian＇ s respiratory system forms in its early development of stage 14 to stage 16. After the formation of branchial arch, outside gills, gills cover and the inside grill gradually form too. With the formation of inside gill, outside gill begin to degrade and eventually disappear; branchial arch is replaced with the inside gill. During the formation of Anuran amphibian respiratory system, the speed of development, the development of form, as well as the form of external gills, are very different owing to the species differences. |
