ABOUT
About Otton Frog
Grows to about 9-14 cm. Breeds from April through October. Lives mainly in mountainous areas, but can also be seen in farmland and parks. It becomes active on humid or rainy days and often comes out onto roads. Males grow larger, making this Japan's biggest frog aside from the introduced American bullfrog. It has five toes with a sharp spur on what corresponds to the thumb, thought to be used by males when fighting each other or during amplexus. Designated a Natural Monument and a Nationally Rare Wild Species in Kagoshima Prefecture, capturing or transferring it — including its eggs — is prohibited. It is very large and impressive, and easy to spot when it comes out onto a road. Its name is said to come from its call.
