We used morphological and modeled kinematic data from 36 stomatopod species and 19 centrarchid species. Huetal2017_stomatopod_data.xlsx contains carapace length (carapace), average relative link lengths (Coupler, Input, Output), and kinematic variables (MinKT, Dist and Ang@MinKT) for all stomatopod species. Note that relative link length refers to the length of the mobile links (coupler, input and output) divided by the fixed link.
