Petropolis River Frog

Thoropa petropolitana occurs at elevations above 800 m (2,600 ft) in rocky areas in forest, or on the forest edge, where it lives on wet rock faces near streams or waterfalls. The eggs are deposited in rock fissures. This formerly common species has undergone significant declines. Threats to it include habitat loss caused by clear-cutting, human settlement, tourism, and fire. However, it has also declined in areas with suitable habitat, suggesting that chytridiomycosis might be a factor. This species occurs in the Serra dos Órgãos National Park, but the park does not protect it from impacts of tourism.
