Trap-Jaw Ant

Meet the trap-jaw ant—small body, serious hardware. Its spring-loaded jaws snap shut in just 0.13 milliseconds, striking prey before it can react. But those powerful jaws aren’t only used for hunting. When danger approaches, the ant aims them at the ground and fires, launching itself into the air like it has an ejector seat built into its own face. One weapon. Two jobs: catch its next meal or save its own life. Engineers are studying this remarkable spring-and-latch mechanism to help build tiny jumping robots. A slow motor cannot match the explosive power of stored energy released in an instant—but the trap-jaw ant has had that technology since birth.
