Most spiders kill with venom, but the uloborid spiders (such as Philoponella vicina) have lost their venom glands entirely. Instead, they kill their prey by using their silk as a murderous garbage-compactor. Once an insect lands in a P.vicina web, the spider rushes over and starts wrapping. It uses 10-20 lines of silk at once and cocoons its prey in over 140 metres of the stuff. This silken shroud compresses insects with such force that it breaks their legs, buckles their eyes, and crushes their internal organs. Once the insect is dead, the spider regurgitates digestive juices all over the silk and sucks up the fluids that remain, leaving behind a dry, hollow shell. (Photo by Robert Whyte)
