Fish of Amazon Basin
The world's largest river basin — the Rio Negro, Solimões, Madeira, Xingu and Tapajós.
2,535 species across 15 families
The Amazon drainage across Brazil, Peru, Colombia, Ecuador, Bolivia and Venezuela — including its great tributaries (Negro, Solimões, Madeira, Xingu, Tapajós, Tocantins–Araguaia, Ucayali, Marañón, Putumayo/Içá, Napo, Juruá, Purus, Branco, Guaporé). Placement here is by FEOW ecoregion; a basin-country fish with no matching ecoregion defaults to the Amazon.
