description: Supplemental Tables Supplemental Table 1. Summary statistics (mean ± standard deviation) are provided for each species in the sample. The number of individuals refers to those used for in vivo grasping trials. Autopodial shape was calculated by dividing autopodial width by length [33]. Since direct measurement was not feasible during in vivo data collection, these values were derived from imprints of species-specific archived autopodia at the Duke Lemur Center. Physiological cross-sectional area (PCSA) was calculated from cadaveric samples, which included eleven individuals from all focal taxa, with intact, unfixed frozen specimens provided by the Duke Lemur Center Biosamples Collection. All specimens were adults without known pathologies, and none were euthanized for this study or showed tissue degradation. Some PCSA measurements were not possible due to tissue availability. Maximal recorded grasping forces, presented in newtons (N) as a percentage of body weight (%BW), and scaled allometric residuals were recorded for each individual, but it was not always possible to collect such data for every individual (e.g., see Trials). Supplemental Table 2. Summary statistics following regressions of in vivo (newtons) and myologically estimated grip forces [e.g., physiological cross section area; PCSA (cm2)] against body mass (kg). All variables linearized and log-transformed prior to analysis such that a slope of one indicates isometry.   Supplemental Table 3. Bilateral differences of in vivo grip forces in the forelimbs and hindlimbs of strepsirrhines. Significant differences highlighted in bold. Laterality analyses of the collared brown lemur (Eulemur collaris) hindlimb was not possible due to a low number of trials. Supplemental Table 4. Interspecific comparisons of forelimb maximal recorded grasping forces as a percentage of body weight (%BW). Cells in red indicate significantly lower grasping forces were observed in the reference species (vertical), while cells in blue indicate significantly higher grasping forces were observed in the reference species (vertical).   Supplemental Table 5. Interspecific comparisons of hindlimb maximal recorded grasping forces as a percentage of body weight (%BW). Cells in red indicate significantly lower grasping forces were observed in the reference species (vertical), while cells in blue indicate significantly higher grasping forces were observed in the reference species (vertical).   Supplemental Table 6. Interspecific comparisons of forelimb scaled allometric residuals of maximal recorded grasping forces. Cells in red indicate significantly lower grasping forces were observed in the reference species (vertical), while cells in blue indicate significantly higher grasping forces were observed in the reference species (vertical).   Supplemental Table 7. Interspecific comparisons of hindlimb scaled allometric residuals of maximal recorded grasping forces. Cells in red indicate significantly lower grasping forces were observed in the reference species (vertical), while cells in blue indicate significantly higher grasping forces were observed in the reference species (vertical).   Supplemental Figure legends Supplemental Figure 1. Bivariate regression of autopodial shape against maximal recorded in vivo grasping forces recorded from each individual grip force presented as a percentage of body weight (%BW) and as a scaled allometric residual. Autopodial shape was calculated by dividing autopodial width by length [33]. The relationship between the maximal recorded in vivo grasping force (%BW) is shown on the left, split by forelimb (top; y = 234.58x - 10.87, R² = 0.28) and hindlimb (bottom; y = 20.63x + 60.36, R² = 0.00). Scaled allometric residuals of maximal recorded in vivo grasping force are shown on the right also split by forelimb (top; y = 0.12x - 0.03, R² = 0.01) and hindlimb (bottom; y = -0.38x + 0.15, R² = 0.05). Species are depicted in different colors (see legend) and limb side is denoted so that the circles represent the left limb while the triangles represent the right
