What configuration does the tail form when a wallaby is moving slowly or grazing to maintain an upright posture?
Answer
A tripod base alongside the hind feet
When a wallaby reduces its speed for activities like grazing or standing still, its primary mode of support changes significantly from high-speed hopping. In this state, the tail acts as a critical structural element, forming a stable tripod base. This base is established by the tail resting on the ground in conjunction with the two hind feet, creating a wide, stable foundation. This tripod stance is functionally necessary because it frees up the small forepaws to be used for manipulating food or grooming while the animal maintains an upright posture.
