Facts

  • sports torpor; said to be able to lay its egg directly in its pouch. Observed upregulation of intake and assimilation during latation (ref: Wiki)

Discussion

  • Predicted milk production exceeds observed because it assumes that babies feed on milk only, while actually a gradual transition to solid food exists
