These carnivorous freshwater fish are primarily found in the Amazon River basin. Known for their sharp teeth and powerful jaws, they are a subject of fascination and often misconstrued as highly dangerous. Their presence is a natural component of the ecosystem, contributing to its intricate food web.
The role these fish play in the environment is significant, as they act as scavengers, consuming deceased animals and helping to control populations. Historically, indigenous communities have interacted with these fish for sustenance, employing various fishing techniques. Their ecological importance far outweighs the commonly held perception of them as purely predatory threats.
