Trunk movements during locomotion in the marsupial Monodelphis domestica (didelphidae) [PDF]

AbstractThe small didelphid cmarsupial, Monodelphis domestica, uses a lateral sequence walk during slow treadmill locomotion and gradually shifts to a trot as speed increases. At higher speeds it changes abruptly to a half‐bound. Cinematographic records suggest significant lateral bending but no sagittal bending of the trunk during the slow walk and a ...
