Elastic energy storage in the hopping of kangaroo rats (Dipodomys spectabilis)

Bipedal hopping of kangaroo rats has been studied by making force plate records and X-ray cinematograph films simultaneously. Calculations using the data so obtained, and anatomical data, show that energy saving by elastic storage is much less important than in kangaroos.
