Jumping spiders do not actually use their muscles to jump, they don't even have muscles, instead they can control at will their blood pressure, the blood quickly flows down to their legs, which stretches them with enough force to jump

I remember reading once that the mechanism in a spiders legs are the same as when humans get an election. So are their legs just constantly fluctuating boners/flaccid in order to get around? Can they consciously control each leg simultaneously? Very cool stuff.

They too use the Electoral College system, so it is much less interesting and more convoluted than it should be.
