| 摘 要： | 应用石蜡切片和扫描电镜技术,对爪鲵(Onychodactylus fischeri)幼体、亚成体和成体3个不同发育阶段的皮肤、外鳃、咽等呼吸器官进行了显微观察与比较分析,旨在揭示爪鲵不同发育阶段各呼吸器官的演化规律.结果表明,爪鲵的皮肤随年龄的增长而逐渐增厚,幼体阶段其背腹皮肤厚度相差不大,亚成体及成体背部皮肤明显厚于腹部;外鳃是幼体和亚成体爪鲵呼吸器官的重要组成部分,随着发育外鳃逐渐完善,到亚成体阶段达到顶峰,随后逐步退化;咽部是爪鲵的重要呼吸器官,幼体期口腔和咽发育不完善,亚成体咽部逐渐发育,至成体时发育完善.

| Abstract: | The conventional histological method and scanning electron microscopy were used to observe the development of skin,external gills,and pharynx in larval,sub-adult and adult individuals of Onychodactylus fischeri. The results showed that skin was thickened with the increase of age. The dorsal skin and ventral skin were not different in thickness at larval stage,while the skin on the back was thicker at sub-adult and adult stages. The external gills was an important respiratory organ at larval and sub-adult st... |
