| 中文摘要: |
| 以透明骨骼双色法对挂榜山小鲵(Hynobius guabangshanensis)成体和亚成体舌器的形态特征进行观察和详细描述。结果表明,在成体中,下舌软骨中部交叉;角舌软骨末端被第一下鳃骨和第一角鳃骨的愈合体遮盖;具有基鳃软骨角状突;第二角鳃骨骨化;尾舌骨骨化,呈"一"字形。在亚成体中,下舌软骨中部未交叉;第一下鳃骨和第一角鳃骨单独存在;无基鳃软骨角状突;第二角鳃骨未骨化;具有第三、第四对角鳃骨,且均为软骨;尾舌骨未骨化,成"1"字形。这些形态特征的改变可能由舌器在成体和亚成体阶段的功能所引起。 |
| 英文摘要: |
| The hyobranchial apparatus features of adult and subadult Hynobius guabangshanensis were observed by clearing and double-staining method. In adult,the middle of hypohyal was crossed; the end of ceratohyal was covered by a complex of hyobranchial Ⅰ and ceratobranchial Ⅰ; basibranchial plate was present; ceratobranchial Ⅱ was ossified; urohyal was also ossified and showed a"一"shape. In subadult,the middle of hypohyal was not crossed; hyobranchial Ⅰand ceratobranchial Ⅰwere present separately; basibranchial plate was not presented,ceratobranchial Ⅱ was not ossified; ceratobranchial Ⅲ and ceratobranchial Ⅳ were present,and both were cartilage; urohyal was not ossified and showed a "1 " shape. These changes of morphological characters may be caused by the function of hynobranchial apparatus in adult and subadult. |
