Mutant Rain Frog Found In Man's Garden In Shunan, Japan

A Japanese rain frog (Hyla japonica) found in a man's garden in Japan has caused a bit of interest due to its odd coloration. The 2cm frog, also known as the Japanese treefrog is common in Japan, and is blue in color rather than its typical bright green, according to a news report in Japan's Asahi Shimbun. The 67-year-old man who found the frog in his garden in Yamaguchi Prefecture, says the frog has been living inside and around the flowerpots that are in his garden.

To determine why the frog was such a strange shade of blue, a biologist with the Yamaguchi Museum was summoned, who said that the frog normally has bright green skin due to blue and yellow pigments that the frog develops, but this frog for some reason is not capable of producing the yellow pigment. The inablity of the frog to produce the yellow pigment is what gives the frog its blue coloration. "It is a statistical oddity,” the researcher told the Asahi Shimbun.
