This blue-from Ishikawa's frog (イシカワガエル, Odorrana ishikawae) was the most exciting encounter among the HerpVenture in Okinawa this time! Though perhaps it's not accurate, but another species of frogs in Japan also appeared blue individual, they supposed it was a miracle which occured only 1/50000 in chance! I guess it's probably the similar situation for this. The lack of yellow pigment might be the reason why a green frog became blue... we were so lucky we can found the mutant blue frog this time, AWESOME!!
這隻藍色型的石川蛙 (the Ishikawa's frog, イシカワガエル, Odorrana ishikawae) 是本次沖繩兩爬大冒險中，最令人興奮的一次發現了！雖然也許不精準，但在日本的別種青蛙也曾出現過藍色的個體，當時被認為是五萬分之一的奇蹟，我猜想藍色的石川蛙也許也差不多吧！黃色素的缺乏可能是造成綠色的青蛙變成藍色的主因，能在野外見到這樣的變異個體實在是太幸運了！

The Ishikawa's frog (イシカワガエル, Odorrana ishikawae) is a big frog endemic to northern Okinawa Island, it's about 9-11 cm of the body length. The endemic species is also very beautiful, it's famous as "the most beautiful frog in Japan". In 2011, a study report (Kuramoto et al., 2011) revealed that the population of Ishikawa's frog in Amami Island as a distinct new species: Odorrana splendida. After that, we can only find the Ishikawa's frogs in the northern Okinawa Island. We were pretty lucky this time, we found one finally after we trekked in the forest for three hours!
石川蛙 (イシカワガエル, Ishikawa's frog, Odorrana ishikawae) 是一種只棲息在沖繩島北部的大型蛙類，體長大約9-11公分。這種沖繩北部特有的青蛙外觀非常的美麗，素有"日本國境內最美的青蛙"稱號。2011年以後在奄美大島的石川蛙被Kuramoto等人發表為新種：奄美石川蛙 (アマミイシカワガエル, Odorrana splendida) 之後，舊稱的石川蛙就只能在沖繩島北部發現了。這次運氣不錯，在森林裡漫步了三個小時，終於找到一隻了！
