I've read that another one such scale-invariant thing is how much time it takes an animal to empty its bladder (at least comparing mammals, of course). I've tried figuring out why, not quite sure though.
Specifically, male dogs, humans, and elephants all take about twenty seconds to empty a full bladder.
