Piranhas River (lower Araguaia River tributary)

The Piranhas River is a river located in Brazil. It is a tributary of the lower Araguaia River, flowing into it in the state of Tocantins. The river is relatively small and primarily drains a region of the Cerrado biome. Specific details about its length, watershed area, and navigability are limited in publicly available resources, suggesting it is not a major waterway. The river likely plays a role in local agriculture and provides a water source for nearby communities and wildlife. The name "Piranhas" suggests the presence of piranhas in the river's waters.
