alexwild > Azteca Cecropia ants guard their tree zealously against intruders.  Working together, they surround and immobilize their opponents by pinning down their appendages.  This trap-jaw ant had a trick up her sleeve, however.  She escaped shortly after this photo was snapped by slamming her mandibles shut with enough force to propel her from the tree and out of the territory of the Azteca.

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.
