Do Piranhas Have Natural Predators? A Detailed Look at Piranhas' Main Enemies

Do piranhas have natural predators? Piranhas have many natural predators in the wild, including egrets, cormorants, herons, electric eels, crocodiles, otters, freshwater dolphins, large catfish, and humans, among others. Let's take a look at the piranha's natural predators below!

The high-voltage current released by a single electric eel can send more than 30 piranhas to the "electric chair" for execution, and then eat them slowly.

The spiny catfish (thorny catfish) is good at using its sharp spines. Once a piranha sets its sights on it, it swims at top speed to beneath the belly of the lowest piranha, and no matter how the piranha swims, it matches its movements in sync. If the piranha tries to bite it, the spiny catfish immediately erects its dorsal spines in anger, leaving the piranha helpless. Moreover, on the Amazon River killer ranking list, the spiny catfish ranks first, while the piranha ranks only fourth.

Because local people catch large numbers of them every year, piranhas have been decreasing in number in the wild, and some species have even become very rare.

The Amazon River basin is rich in a plant whose roots contain a poisonous sap. People mix this poisonous sap into chopped beef and pour it into lakes or rivers where piranhas live. In less than 1 hour, the surface of the lake is covered with the bodies of these piranhas.
