Red-bellied piranha   (Pygocentrus nattereri)
Category: Fish

 

 

Red-bellied piranhas are omnivorous foragers and scavengers found in the Amazon Basin of South America. Their diet includes insects, worms, plants, crustaceans, and fish – they are not obligate carnivores. They tend to travel in shoals as a means of defense against predators, but rarely engage in group hunting behavior. Red-bellied piranhas are found over a larger geographic area than any other species of piranha and are also popular aquarium fish.
