本標本為1931年由平坂恭介在恆春郡大樹房採集，為台灣首筆儒艮的正式紀錄。平坂恭介專業為水生動物，著有《台灣水產雜誌》
This specimen of dugong was collected by Professor Kyosuke Hirasaka from Hengchun, 1931. This was the first record of dugong in Taiwan. Professor Hirasaka was an expert in aquatic animals and published articles in “Taiwan Fisheries Magazine”經確認，此刊無官方英譯名，所以暫時就翻成這樣。
