The pirarucu, one of the largest freshwater fish in the world, is typically found in the slow-moving waters of the Amazon River Basin. It inhabits rivers, floodplains, and lakes, particularly in areas with abundant vegetation and submerged structures. This species prefers warm, shallow waters where it can find ample food and shelter. The pirarucu is also known for its ability to breathe air, allowing it to thrive in oxygen-poor environments.
