中文摘要 | 為探討花身雞魚(Terapon jarbua)的味蕾之分佈及形態學特徵,本報告利用光學顯微鏡及掃描式電顯分別觀察之。結果顯示本魚種有三型味蕾與其他魚種相似,型Ⅰ與型Ⅱ具有突起於表皮組織之味蕾,唯型Ⅱ周圍有顯著之凹槽;型Ⅲ之突起不明顯,需以其味蕾孔(taste pore)辨識之,唯本魚種獨具一型味蕾分佈于舌尖之邊緣,該型具有數個現種間差異;但與虹鱒較相似,密佈于齒間周圍,呈現肉食魚種之特徵;且其體表味蕾極稀,推測本魚種棲居清晰水域,不賴體表味覺找尋食物。 |
英文摘要 | To investigate the types and distribution of teste buds in thornfish (Terapon jarbua), light-microscopie and scanning-electron-microscopic examinations are performed herein. According to these results, the species has four morphologically different types of taste buds, three of them are similar to those of the other studied teleosts. One unique type, distributing only at the margin of "tongue" tipe, has multiple buds on each single taste papillae. The distribution of taste buds in thornfish has nore similarity to those in rainbow trout, indicating a carnivorous feeding-habit. Sparse external and dense internal teste systems suggested that thornfish should be an open-clear water habitat and depend on oropharyngeal taste buds for distinguishing the acceptability of uptaking food rather than for searching for the food source. |
