Comparison of hind limb angle trajectory plots across several lizard species. Data for species, apart from the current study’s C. bibronii, were obtained from previously published material as stated in the legend. The light grey box represents the stance phase. All data, separately for stance and swing, were interpolated to the same timings, so that speed was not a confounding factor and to observe the similarities and differences between trajectories easily. Femur retraction was remarkably similar across species, but the greatest differences occurred in the most distal element, the ankle. The gecko undergoes greater angular excursion during stance, whilst in the swing holding the ankle at a remarkably fixed angle compared to all other lizard species
