| 内容記述 | The Indo-West Pacific genus Taenioides (Gobiidae), called as eel-goby or worm goby, is characterized by unique features: e.g., well developed dermal folds with papillae on the head, distinct barbels on the ventral head, a scale-less body, enlarged fanglike teeth on the jaws, and the Y-shaped second anal-fin pterygiophore. Taenioides anguillaris (Linnaeus, 1758), T. gracilis (Valenciennes in Cuvier and Valenciennes, 1837), T. kentalleni Murdy and Randall, 2002, and T. snyderi Jordan and Hubbs, 1925 have been recorded from Japanese waters. However, distributional range of each species in Japan is unclear because of their morphological similarity. Therefore, current distribution of species of Taenioides in Kagoshima Prefecture and adjacent area are clarified in this study on the basis of a large number of voucher specimens. Some new ecological knowledge, including diets and air breathing behavior, are also described. Our aquarium observation showed that T. gracilis and T. snyderi sucked in air from above the water surface and kept floating for a while. This behavior of T. gracilis was observed in their burrowing hole on the tidal flats during our field survey, suggesting that air-breathing is an adaptation to the low-oxygen tidal flat environment. Moreover, the stomach contents and swimming behavior observation revealed that Taenioides is likely to feed inside their burrows during low tide and outside the burrows during high tide. Examination of a large number of specimens in this study revealed that the arrangement and number of barbels on the ventral head, previously regarded as a stable character to distinguish species (2-3-2 for T. gracilis, 2-2-2 for T. snyderi), were somewhat variable (2-2-2, 2-3-2, 3-3-2, and 2-4-2 for the former, 2-2-2, 2-3-2, and 2-2-2-2 for the later). The distance between lacethe posterior end of pelvic-fin base and the anus in T. gracilis is longer than head length in specimens at least over 64 mm standard length (SL) and this character can be used to separate from T. snyderi [invalid in smaller specimen (37.8 mm SL) of T. gracilis]. Two morphotypes of T. gracilis were found during this study: one is distributed from India to Japan; the other is in the Gulf of Thailand. Comparison of specimens from Japan with those from the Gulf of Thailand showed that the latter had several features, including a slightly shorter trunk, undeveloped lip on the maxilla posteriorly, and fewer meristics which differed from the former. | |||||
