Actually, their tail really does act as a third leg. When they "gallop", they use their tail like a rear leg and spring off of it, putting as much pressure on their tail as they put on their feet combined.

It's basically a 3-legged gait.

If they are sprinting isn’t it more like 5-legged? I’ve heard the term pentapedal used in reference to kangaroos

I've never seen a kangaroo sprinting on all 5 legs. Usually, they are just doing the hopping sprint with their hind legs and tail.

They say "pentapedal" because they are counting the tail as fifth leg, but not because they are using all 5 at once.
