Uncover the secrets of crocodile locomotion! This study investigates the diverse asymmetrical gaits used by juvenile *Crocodylus johnstoni*, the Australian freshwater crocodile. Using high-speed video analysis, researchers examined the limb kinematics of these animals, revealing a remarkable flexibility in limb coordination. The research identified various gait patterns, including rotary gallop, which may offer high maneuverability, and transverse gallop, providing greater stability. Speed increases were achieved primarily through half-bound and bound gaits, with bound being the sole gait observed at velocities exceeding 2 m/s. Kinematic analysis revealed that speed increases were primarily achieved by increasing stride length in both forelimbs and hindlimbs. This detailed analysis sheds light on the unique locomotion strategies of crocodiles, highlighting that their asymmetrical gaits are distinct from those of lizards transitioning into bipedal runs and differ in some respects from mammalian gaits. These findings contribute to a broader understanding of vertebrate locomotion and the evolutionary adaptations that enable diverse movement patterns.
This study on Crocodylus johnstoni's gaits fits well within the Journal of Zoology's scope, as it explores animal behavior and biomechanics. The detailed analysis of crocodile locomotion adds to the journal's contributions in understanding animal adaptations. The paper strengthens the journal's content by providing insight into the diverse strategies employed by reptiles to achieve efficient movement.
