This animation (.swf) was created from a synchrotron-based CT scan of the carapace and chelicerae of a New Zealand trap-jaw species. The New Zealand trap-jaw spiders, so far, have the fastest known chelicerae movements within the family. The thick bundles of fibers that run horizontally from the chelicerae to the back of the carapace likely have elastic elements that store energy. The chelicerae move extremely rapidly as a result of this energy being rapidly released. This animation was created by Dula Parkinson on beamline 8.3.2 at the ALS.
