alexwild > The partially-closed mandibles of an Odontomachus coquereli trap-jaw ant.  When the trap is set, the mandibles are held open at about 180º.  Notice the tiny mites riding on this ant's mandibles.  The mites are apparently able to hold tight even when the jaws of their host slam shut at high speed.  Madagascar.
