Molecular phylogenetics of the Neotropical fish family Prochilodontidae (Teleostei: Characiformes) [PDF]
Migratory detritivores of the characiform family Prochilodontidae occur throughout the freshwaters of much of South America. Prochilodontids often form massive populations and many species achieve substantial body sizes; a combination that makes them one of the most commercially important fish groups on the continent.
