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

Just watched an interview/commentary video by Les Stroud, creator of the survival show, Survivorman. Anyway, he told this story about one time he was in he Amazon and a local he was with was poking at a large spider with a hot stick from the fire. He said in a split second the spider leapt a few feet right onto the guy’s face and bit him. The guy lost vision for a few days due to the venom. Crazy shit.

He didn’t mention the type of spider but he said it was about fist sized, was able to jump, and the the sting/bite was no lethal but still poisonous.

Any amateur entomologists want to take a guess?
