Bite force mechanics and allometry of piranha (Serrasalmidae)

The bite force of the piranha (Serrasalmidae) has drawn considerable attention due to its ability to effectively capture and masticate prey. Herein, we analyze theoretical anterior bite forces using a lever approach and compare them to in vivo maximum bite forces. We provide a mechanics analysis that explains the scaling allometry of the bite force (F-output) with the length of the fish (l), F-output alpha l(2).

Automated summary

The study focuses on the bite force of piranhas, showing a scaling relationship between the bite force and the length of the fish. A mechanics analysis is provided, explaining the proportional relationship between the bite force and the fish length.
