Fish[edit]
With more than 2,200 species the Amazon Basin has a larger fish fauna than any other river basin on Earth, and Amazonia is the center of diversity for Neotropical fishes.[6] The Amazon Basin is home to the red-bellied piranha, an omnivorous forager that encompasses a larger geographic area than any other piranha species. The remarkable species richness can in part be explained by the large differences between the various parts of the Amazon Basin, resulting in many fish species that are endemic to small regions. For example, fauna in clearwater rivers differ from fauna in blackwater rivers, fauna in slow moving sections show distinct differences compared to that in rapids, fauna in small streams differ from that in major rivers, and fauna in shallow sections show distinct differences compared to that in deep parts.[7][8]
