藍色型的石川蛙 (blue-from Ishikawa's frog, Odorrana ishikawae)
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！
