Abstract

A SEM study on morphology of lingual papillae of Korean long-fingered bat (Miniopterus schreibersi fuliginosus) and Savi's Pipistrelle (Pipistrellus savii) was conducted. Three kinds of lingual papillae were observed: filiform, fungiform, circumvallate papillae. Filiform papillae were divided into two types; the type 1 had a group of needle-like projections, and was distributed throughout the front half of the tongue; the type 2 had a smooth and thick body, and was found in rear half of the tongue. 35 to 45 fungiform papillae were found on the dorsal surface of the tongue in both species. They were observed along the lateral margins and were also found on front and rear end part of the tongue. There were two to three noticeably large fungiform papillae arranged in a straight line on the region between lingual prominence and circumvallate papillae. There were two circumvallate papillae close to the rear end of the tongue. They were large and round, each having two layers of pads. The overall morphology of lingual papillae of M. schreibersi fuliginosus and P. savii was found to be similar with other Chiroptera. However, few but noticeable differences were found among the filiform papillae and fungiform papillae. Type 2 filiform papillae differed in that bifid and trifid configuration were found in M. schreibersi fulginosus unlike in P. savii. In addition, numbers of large fungiform papillae located in the center of posterior region of the tongue were different with M. schreibersi have three while P. savii having only two.

주사전자현미경을 이용하여 한국산 긴가락박쥐(Miniopterus schreibersi fuliginosus)와 검은집박쥐(Pipistrellus savii)의 혀유두의 형태를 관찰하였다. 본 연구에서 두 종 모두 세 가지의 혀유두, 즉, 실유두, 버섯유두 그리고 성곽유두가 관찰되었다. 실유두는 다시 두 종류로 세분화되어졌으며, 침상의 돌기물을 갖는 유형1은 혀의 전반부의 1/2 지점까지 분포하며, 유형2는 밋밋하고 두꺼운 돌기물을 갖고 있으며 혀의 후반부의 1/2에 분포한다. 두 종 모두 35~45개의 버섯유두가 혀의 표면에서 관찰된다. 이들 버섯유두는 혀의 측면과 혀의 전반과 후반부의 끝 쪽에서 나타난다. 두 종의 버섯유두는 각각 두 개 혹은 세 개의 매우 큰 유두로 혀의 후반부 중앙에 일직선으로 배열되어 있다. 두 개의 성곽유두는 혀의 후반부 끝쪽 가까이에 분포하고 있다. 이들 성곽유두는 크고 둥글며 각각은 두 층의 pad를 갖고 있다. 긴가락박쥐와 검은집박쥐의 혀유두의 전체적인 형태는 다른 익수류와 유사하였다. 그럼에도 불구하고, 두 종 사이에 드물지만 주목할 만한 차이점이 실유두와 버섯유두에서 나타났다. 검은집박쥐와는 달리 긴가락박쥐의 유형2의 실유두는 두 개 혹은 세 개의 돌기를 가지고 있었다. 혀의 후반부 중앙에 위치하고 있는 큰 버섯유두의 경우, 긴가락박쥐에서는 3개, 검은집박쥐에서는 단지 2개만 관찰되었다.
