Results for our minimal (“min”) and maximal (“max”) models are shown. Also displayed are segment percentages of body mass (“Mass/body mass”; for minimal or maximal models respectively; for head segment data are shown relative to minimal models) and the ratio of segment masses for maximal vs. minimal models (“Max/Min”).
