Megapiranha put T. rex’s bite to shame, says study

Black piranha and megapiranha have the most powerful bites of carnivorous fish.

Tyrannosaurus rex and megalodon, a gigantic shark that preceded the great white, have nothing on the black piranha and the extinct megapiranha when it comes to chomping power. Researchers at George Washington University report that, relative to its size, the megapiranha bite was more powerful than T. Rex and history’s largest shark. According to the study published in Scientific Reports, the black piranha was determined to have a biting force behind its powerful teeth of up to 320 Newtons.

“Comparisons of body size-scaled bite forces to other apex predators reveal S. rhombeus and M. paranensis have among the most powerful bites estimated in carnivorous vertebrates. Our results functionally demonstrate the extraordinary bite of serrasalmid piranhas and provide a mechanistic rationale for their predatory dominance among past and present Amazonian ichthyofaunas,” the authors write in their study.
