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), $F_{output}\alpha l^2$.

食人鱼（Serrasalmidae）的咬力力学和异速测量法

食人鱼（Serrasalmidae）的咬合力由于其有效捕获和咀嚼猎物的能力而备受关注。在这里，我们使用杠杆方法分析理论上的前牙咬合力，并将其与体内最大咬合力进行比较。我们提供了力学分析，解释了咬合力的按比例缩放角度$（F_{ØüŤpüŤ}$）加上鱼的长度（l），$F_{ØüŤpüŤ}\alpha {升}^2$。
