The Parnaíba River (Portuguese: Rio Parnaíba) is a river in Brazil, which forms the border between the states of Maranhão and Piauí. Its main course is 1,400 km (870 mi) long and the Parnaíba River Basin covers 344,112 km2 (132,862 sq mi).[1] The Parnaíba River rises in the Chapada das Mangabeiras range, and flows northeastward to empty into the Atlantic Ocean, being the longest river entirely located within Brazil's Northeast Region.[2] The middle and upper regions of this river are separated by the Portuguese: Boa Esperança Hydroelectric Power Plant dam, but is otherwise navigable.[3]

Ecology
The fish species richness in the Parnaíba River Basin has traditionally been considered impoverished, but this has been disproven by recent surveys, which have recorded about 140 native species (including several that remain undescribed) and about 40% of these are endemic.[1] One of the basin endemics is the freshwater stingray Potamotrygon signata.[4] More than 70% of the fish species in the basin are members of either Characiformes or Siluriformes.[1] The fauna in the headwaters has not yet been thoroughly surveyed. In addition to the natives, there are seven introduced fish species in the basin.[1]
The river delta is protected by the 313,800 hectares (775,000 acres) Delta do Parnaíba Environmental Protection Area, created in 1996.[5] The river's delta has large stands of mangrove,[6] as well as dunes, beaches, marshes and other habitats.[7] The delta is considered an Important Bird Area and is home to species such as scarlet ibis (Eudocimus ruber) and rufous crab hawk (Buteogallus aequinoctialis).[7]
Two species of aquatic turtles are endemic to the general region, the Maranhão slider (Trachemys adiutrix) that is found in the delta and the side-necked turtles Mesoclemmys perplexa found inland, but neither is entirely restricted to the Parnaíba River Basin.[8][9]

[de] Rio Parnaíba
Der Rio Parnaíba ist ein Fluss im Nordosten Brasiliens, der fast in seinem ganzen Lauf die Grenze zwischen den Bundesstaaten Maranhão und Piauí bildet. Er entspringt auf einer Höhe von 700 Metern im Brasilianischen Bergland in dem Bergzug Chapada das Mangabeiras, der sich seit 2002 im Nationalpark Nascentes do Rio Parnaíba befindet, und fließt 1716 km nordöstlich bis in den Atlantischen Ozean. Im mittleren und oberen Teil des Flusses gibt es Wasserfälle, aber bis zur Mündung des Rio Canindé ist er schiffbar. Das Flussdelta, Delta do Parnaíba, befindet sich in Piauí und soll das drittgrößte Flussdelta der Welt sein. Dort befindet sich die Stadt Parnaíba mit einem Hafen.- [en] Parnaíba River
