Answer:
Kangaroos are well known for hopping on their muscular hind legs with their long tail outstretched behind. But these grazing animals spend much more time moving slowly than hopping quickly [1], and when they do so, kangaroos use their tail quite differently. They plant it on the ground in sequence with their front and hind legs in a distinctive gait referred to as ‘pentapedal’ locomotion [2,3], with the fifth point of contact being the tail (figure 1; see also the electronic supplementary material, Video).
