We used morphological and modeled kinematic data from 36 stomatopod species and 19 centrarchid species. Huetal2017_centrarchid_data.xlsx contains head length (HeadLength), jaw lengths (Jawlength), average relative link lengths (Coupler, Input, Output), and kinematic variables (MinKT, ScaledGape and Ang@MinKT) for all centrarchid species. Note that relative link length refers to the length of the mobile links (coupler, input and output) divided by the fixed link.
