Piranha and sharks are fish, and they are very fierce fish. They are mainly carnivorous and can prey on many animals around them. Whether piranha or shark is more powerful depends on the specific situation, whether they appear alone or in groups, and the species of shark.
Sharks are generally large, especially some very fierce sharks, while piranhas are relatively small, their body length is only 20-30 centimeters. Therefore, if the piranha alone is compared with the shark alone, the shark is still more powerful. Of course, there are different species of sharks, such as the "pygmy dogfish", whose body length is only 6-8 inches, so it may not be as strong as piranha. Groups of piranhas are very powerful, and piranhas are more powerful if they are in groups than if they are individual sharks. Their ability to hunt is very strong, and they can eat very large animals. In addition, there is another situation, that is, sharks are also in groups, at this time generally speaking, sharks are powerful.
Crocodile is also a ferocious animal. If a single piranha encounters a crocodile, then the crocodile is more powerful, it is easy to become crocodile food. However, if groups of piranhas encounter crocodiles, then it may be that piranhas are fierce, and crocodiles have little hope of winning. But crocodiles sometimes come ashore, and when they do, the piranhas can't do anything about it.
