Maximum speed measured in controlled conditions for each one of the 68 elephants composing the database of Hutchinson et al.²⁵. Also shown are the lower bounds of the predictions from both the G-regression and the H-model given, respectively, by Eq. (3) with a_r = 0.70, and Eq. (6) with b_r = 0.74 (see text for details).
