- Pink River Dolphin (Boto): This highly intelligent and flexible cetacean navigates the flooded forests, using echolocation to find fish among the trees. It holds a central place in Amazonian mythology.
- Giant Arapaima: One of the largest freshwater fish on Earth, growing up to 3 meters in length. It is an air-breather, surfacing every few minutes to gulp air. Its size and value as a food fish have made it a target for overfishing, though sustainable management projects are showing success.
- Black Caiman: The apex predator of the Amazon waterways. Growing up to 5 meters, it dominates the food chain, preying on fish, birds, and mammals that come to the water's edge.
- Piranhas and Piranha: While famous for their reputation, most piranha species are scavengers or feed on other fish and insects.
- Giant Otters: Highly social and vocal mammals that live in family groups. They are top predators, feeding almost exclusively on fish.
