Piranha have one of the strongest bites in the fish kingdom. Their bite is almost three times of their body size. The muscles on their jaws are estimated to be two percent of the total muscles in the body giving them such a strong biting force. Although they have such strong bite Piranhas rarely attack humans.

The piranha jaw is strong, with the largest in the species being able to bite with a maximum force of 3 times their own body weight. The black piranha has the strongest bite force recorded for bony fish, according to a 2012 study by scientist Justin R. Grubich. If bitten, a piranha can cut through a human hand in minutes.

Piranhas aren’t just known for their sharp teeth; they’re also known for how hard they can bite. Though they’re small (usually between 6-12 inches), there’s nothing small about the piranha’s bite. Piranhas have extremely tough jaw muscles, and all those jaw muscles are designed for one thing; biting. Piranhas can bite with a bite force of 70 PSI.
