Supplementary data for Figure 6 in Biomechanics of the arboreal locomotion of reptiles.

<b>Figure 6. Safety factors for different gripping systems.</b> Safety factors were estimated as the maximum sustainable force divided by the body weight force. Values below 1 suggest a species is not able to support its own bodyweight on a vertical surface. Attachment forces were normalized for the full body, i.e. gecko clinging forces for one hand were multiplied by four. Differences in surface frictional coefficients were ignored. Claws appear to show the highest safety factors, followed by adhesive pads. The grasping hands of chameleons, and the axial body grasping of snakes show the lowest safety factors. Data is compiled from (Autumn et al., 2006; Byrnes &amp; Jayne, 2014; Cobos &amp; Higham, 2022; Herrel et al., 2011; Irschick et al., 1996; Losos et al., 1993; Tulli et al., 2011)
