Open encyclopedia reference
The Otton frog (Babina subaspera) is a species of frog in the family Ranidae. It is endemic to the islands of Amami Ōshima and Kakeromajima in the Ryukyu Islands, Japan. Its natural habitats are subtropical or tropical moist lowland forests, freshwater marshes, and intermittent freshwater marshes. Once considered a delicacy as a source of food, it is now threatened by habitat loss through deforestation, and predation by introduced mongooses. Otton Frogs have a lifespan of approximately 7 years which is significantly different to common frog species' life span of 10 -12 years. Due to the isolated island ecosystem, many factors play into the endangerment and the shorter lifespan of the species.
It is one of only two species (the other being Babina holsti) to possess a "pseudothumb" on the forelimbs.
