They are found in South America's rivers, swamps, and flooded areas.
Piranhas are typically between 15-30 cm (6-12 inches) in length.
They have razor-sharp teeth that can easily slice through flesh.
Piranhas are opportunistic feeders and will eat a variety of prey, including fish, crustaceans, and even fruits and seeds.
They are known to form groups, which can number up to 100 individuals.
Piranhas are not known to attack humans, except in extremely rare cases when the water is low and food is scarce.
They are not considered a threat to humans and are fished for food and sport.
Some species of piranhas are considered endangered due to overfishing and habitat destruction.
Piranhas have been known to feed on dead or wounded animals, and it is not a common behavior to attack healthy animals.
