摘要：

Wallabies and kangaroos increase their speed of hopping with little increase in their use of metabolic energy, apparently by means of elastic energy savings in their hindlimb tendons1,3. Here we report that, because of this storage capacity, female tammar wallabies can carry large young in their pouch at very low cost, with no increase in metabolic energy expenditure.
