Amphibians, such as frogs and toads, have to dwell in damp environments because of their ability to breathe through their skin. It is damp and rainy in the Sun Moon Lake area and if you observe the surroundings carefully, you can find their tracks. Amphibians are nocturnal and they are mostly seen at the rim of lake, in undrained low lands, rhines, streams, farmed lands, paddy fields, bamboo woods, leaf heaps under orchards, bushes, the auxillary part of Alocasia macrorrhiza, and small tree holes with water or bamboo barrels. You can hear the united chorus between frogs around the lake and also along with the background music from other insects.
