Digging locomotion of Namib Golden moles has been studied by making X–ray cinematograph films, and the morphology of their locomotor system investigated by means of radiographs and dissections. Biomechanical interpretations of the data so obtained show that moving forwards results from a cyclical compacting and decompacting of the surrounding sand. The whole step–cycle IS made up of a buttressing phase followed by several digging propulsion phases.
