Using webs to catch prey is all well and good, but it almost seems tame compared to what spitting spiders do to their victims. To subdue a target, the killers take aim and fire twin streams of venom-drenched silk out of their fangs. At a top speed of 62 miles per hour, the fibers move in a wide-arced, zig-zag pattern. In addition to being coated with poison, this silk drips with a super-sticky glue. Once victims are enmeshed, the glue-covered fibers will shrink, constricting the unfortunate prey. Eventually, the spitting spider will administer a venomous bite and put the trapped entrée out of its misery.
