Rio Pardo is a river located in the state of Bahia, Brazil, flowing through the domain of the Atlantic Forest along Brazil's eastern coastal drainage. The river originates with its upper and middle portions in the neighboring state of Minas Gerais before its lower stretch enters Bahia, where it eventually meets the Atlantic coast. This coastal drainage system supports a diverse mix of freshwater and estuarine fish species, reflecting the river's transition from inland headwaters to its lower tidal reaches near the sea. The surrounding Atlantic Forest biome lends the river a rich ecological character, with riparian vegetation and a variety of aquatic habitats ranging from headwater streams to broader, slower lower reaches.
