- Abstract
Bat plays many important roles environmentally and economically as pest control, nutrient cycling, pollinator as well as guano’s producer. The threat of extinction arises due to environment damage or illegal hunting, thus, conservation effort is crucial that can be approached through studying the histological structure of tongue to understand its food preferences. In Yogyakarta, Indonesia, there are two bats, Rhinolophus pusillus and Miniopterus schreibersii which live in the same habitat. This study evaluated the histological structure of tongue of R. pusillus and M. schreibersii. Three individuals each species was caughted using sweep net and mist net, further anesthetized using chloroform and sacrificed. The tongues were collected and fixed in 10% neutral buffered formalin. Histological preparation was done based on paraffin method with Hematoxylin Eosin staining and sectioned with 6 µm thickness. The histological data were compared descriptively. The results showed that the histological structure of tongue of R. pusillus and M. schreibersii are similar. There are 3 layers; mucous, submucous, and muscular layers. The keratinized stratified squamous epithelial layer protrudes as filiform, fungiform, and circumvallate papillae. The muscular layer arranged in 3 orientations. We found serous and mucous producing cells in salivary gland’s of both bats. The salivary glands of R. pusillus are found in the sublingual and anterior part of the tongue, whereas, the salivary gland of M. schreibersii are found in the antero-inferior part and posterior part of the tongue. Based on these results, we suggested that both species have similar tongue structure thus may develop similar food adaptation.
