Project Noah Fun Fact: Arapaima are among some of the largest freshwater fish in the world sometimes attaining lengths as much as 15 feet long (4.5 m). This fish is indigenous to the Amazon River region of South America. Because it has a labyrinth system of breathing that allows it to breath air, it is able to survive in areas of poorly oxygenated water. It is a predatory fish and feeds upon other fish, crustaceans and the occasional small mammal that wanders too close to the water.
