Our goal is to verify the effect of the recent rise in ocean temperature on the biology of batoid species. The distribution pattern and species composition of batoid species were examined in both Ariake Bay and Chinese coastal waters. Many common species in both study areas were recorded, indicating the great similarities in species composition of both areas. Additionally, for longheaded eagle ray Aetobatus flagellum which has been increasing in western Japanese coastal areas for decades, the distribution, diel behavior and the relationship between behavior and ambient water temperature were investigated and analyzed. One of the possible causal factors to increase their population size in Japanese waters might be the recent rise in water temperature in winter that could make it possible to stay in the adjacent areas of Ariake Bay.

我们的目标是验证最近海洋温度上升对蝙蝠物种生物学的影响。对有明湾和中国沿海沃茨海域的蝙蝠蛾种类组成和分布格局进行了研究。在两个研究区都记录到了许多共同种，表明两个研究区的物种组成有很大的相似性。此外，对日本西部沿海地区几十年来不断增加的长头鹰鳐Aeacentatus鞭毛的分布、昼夜行为以及行为与环境水温的关系进行了调查和分析。在日本沃茨增加其种群规模的可能原因之一可能是最近冬季水温上升，这可能使其有可能留在有明湾的邻近地区。
