Evolutionaryanen: All spiders jump, and they're just not letting us in on the fun. Jumping spiders have binocular eyes, hydraulic legs, and can leap the equivalent of a football field to come steal your girl. But also, they know how to strut very casually. Their typical jumps are shorter, but they do like a succession of them. So they will jump, jup, jump, jump,jump to navigate things really quickly.
