Rio Amazon

Rio Amazon recreates the freshwater habitats of the world's largest river system, featuring piranhas, freshwater stingrays, and other Amazonian species in lush, tropical exhibits. The gallery highlights the extraordinary biodiversity of the Amazon Basin, which contains more species of freshwater fish than any other river system on Earth.

The Amazon River system contains over 3,000 known fish species — more than the entire Atlantic Ocean. Piranhas, though feared for their razor-sharp teeth, are mostly scavengers that play important ecological roles in maintaining river ecosystem health by consuming dead and dying animals.
