The jaws of the Dracula ant (Mystrium camillae) go from 0 to 200 miles per hour in 15 microseconds.

These include sterile minor workers (who perform the majority of colony tasks), soldiers (who use their remarkable plate-shaped heads to defend colony entrances, acting as “living doors”), and gynes (reproductively-capable females that share the same head shape as soldiers and use it for defense early in colony foundation): here.
