Piranhas attack any living species that enters the water they swim in, including man, yet they are kept as pets all over the world. There are more than 20 known species in South America—the Black Piranha is the largest and is recognized for having the strongest bite among living fish, with a force more than 30 times greater than its weight.
Piranhas’ sharp teeth cut lines easily, making them difficult to catch. When they lose or cut a tooth, it grows back. In addition, they can sense weakness and fear in their prey.
Piranhas are very shy, untrusting fish.
Best Animal to Adapt With
The fierce Piranha is bursting with stamina but falls short in charisma and intelligence. For this reason it’s best suited to adapt with two animals that are strong in both categories, the Toucan and the Macaw.
Young piranhas taste delicious, therefore man and many animals prey upon them, including birds, otters, water snakes, caimans, turtles and other piranhas.
Increasing Their Survival Rate
Piranhas have no special status on the IUCN Endangered Species Red list. They reproduce very quickly, making it difficult for them to be endangered. As long as hunting is discouraged, the Piranha population should remain intact.

Many stories are recounted about schools of piranhas turning horses, cattle and people into skeletons within seconds. Much folklore contends that they are attracted by blood, and that when their population is attacked, hundreds of swimmers are bitten by schools of these ravenous fish, numbering more than a thousand. In his 1914 book, Through the Brazilian Wilderness, U.S. president Theodore Roosevelt calls piranhas, “The most ferocious fish in the world,” and states that “Piranhas habitually attack things much larger than themselves. They will snap a finger off a hand incautiously trailed in the water; they mutilate swimmers—in every river town in Paraguay there are men who have been thus mutilated; they will rend and devour alive any wounded man or beast; for blood in the water excites them to madness. They will tear wounded wild fowl to pieces; and bite off the tails of big fish as they grow exhausted when fighting after being hooked.”
