About Buergeria japonica (Hallowell, 1861)
Buergeria japonica is a small to medium-sized frog species. Adult males have a snout-vent length of around 3 cm (1.2 in). This species is common, and can be found in a wide range of habitats including rivers, intermittent rivers, freshwater marshes, intermittent freshwater marshes, freshwater springs, geothermal wetlands, irrigated land, canals, and ditches. It is locally threatened by habitat loss. Buergeria japonica normally breeds in slow-moving water within ditches and small streams. Some populations native to Taiwan, however, also breed in geothermal hot springs. In this geothermal habitat, frogs can breed year-round. High temperatures in these environments speed up tadpole growth, and these unusual habitats also tend to have lower levels of competition. Tadpoles of this species can tolerate water temperatures up to approximately 42 °C (108 °F), but few tadpoles enter pool areas where temperatures exceed 37 °C (99 °F).
