# A Mechanical Approach for Comparing Jaws in Fishes

## TL;DR

This paper introduces a mechanical method to compare fish jaws using engineering principles, aligning with biological findings.

## Contribution

The novel contribution is applying industrial linkage mechanism parameters to analyze and compare fish jaw structures.

## Key findings

- Seven fish species from different families were analyzed using mechanical parameters.
- The approach enables meaningful comparisons of jaw mechanisms previously unattainable.

## Abstract

This paper aims to propose an quantitative engineering approach to study and compare the jaw mechanisms of different marine species, considering essential mechanical parameters generally used to evaluate the performance of industrial linkage mechanisms. By leveraging these parameters, the paper demonstrates how the species’ characteristics and behaviors align with the findings of biologists, enabling a meaningful comparison that was not previously possible. Seven fish species from various families are chosen to maintain a generic approach.
