Locomotor endurance times (20) of six monitor lizards (V. exanthematicus) with functional (control) and impaired (experiment) gular pumps (values ± SEM). Endurance times of gular-impaired lizards were statistically significantly shorter at 2 and 3 km hour−1 than the endurance times of the same animals under control conditions (pairedt test; P < 0.01).
