Chungan Sucker Frog

The Chungan Sucker Frog (Amolops chunganensis) is a Least Concern torrent frog in the family Ranidae, endemic to central China, particularly associated with the mountains of Chongqing (formerly Chungan County, from which the species name derives) and surrounding areas. The genus Amolops, commonly known as torrent frogs or cascade frogs, is adapted for life in and around fast-flowing mountain streams, with expanded toe pads and sucker-like discs that allow clinging to wet, smooth rock surfaces in high-velocity water. Breeding occurs in stream environments, where males call from boulders at the stream edge and larvae develop in oxygenated torrent pools with specialized mouthparts for adhering to rock substrates. A. chunganensis inhabits subtropical and montane forests at elevations ranging from low to mid altitudes in Sichuan and Chongqing. The IUCN assesses this species as Least Concern, reflecting a relatively wide distribution within suitable stream habitats across central China. However, it faces ongoing pressure from water quality degradation, dam construction and stream modification, deforestation, and pollution from agricultural and urban runoff. Amolops frogs are sensitive to siltation and chemical contamination of breeding streams.
