>>13560574I don't want to get into semantics, but galloping/limping is a mode where either legs perform different and essential functions. Arms being uncritical to bipedal motion can be doing anything. I think the first time I have encountered this concept was how our motions work for the laws of the macrouniverse. I think it was a shrimp, or maybe something smaller, where if it kicks its legs the way we do, the symmetry would cause it to spin. Instead it uses angular momentum conservation to move. I can't remember what it was called. The parallel is how changing swing orientation will allow you to swing higher and higher.
The exact motion the critter did could be comparable to your hand if you have to paddle using only your wrist/finger tips. The paddle would be your fingers fully extended, and the return to initial state would be a fingers curled in a slower return motion. I don't remember the video or I would just post the link.
