Meet the Red-bellied Piranha

The Red-bellied Piranha (Pygocentrus nattereri) is a species of freshwater fish that belongs to the Characidae family. Known for their sharp teeth and powerful jaws, these fish are native to the rivers of South America.

Habitat & Range

Red-bellied Piranhas are primarily found in the Amazon River basin. They thrive in warm freshwater environments, including rivers and floodplain lakes. Their range also extends to other river basins in South America, such as the Orinoco and Paraná.

Despite their fearsome reputation, these fish are an integral part of the aquatic ecosystem, playing a role in controlling the population of other species.

Diet & Behavior

The diet of the Red-bellied Piranha is diverse, including insects, worms, crustaceans, and fish. While they are opportunistic feeders, their feeding frenzies are less common than popularly believed.

In their natural habitat, these piranhas often exhibit schooling behavior, which serves as protection against predators. They are known to communicate with each other through acoustic signals.
