For clues into how Myrmoteras executes its power-amplified strike, scientists examined the ants first under a microscope, then using micro computed tomography (micro-CT), a three-dimensional imaging system that uses X-rays to visualize the internal structures of small specimens. Their observations allowed them to piece together a model of how the jaws likely works. Researchers detected a feature of the ant's mandible joint that allows its jaws to lock open. Before the strike, a lobe on the back of the ant's head compresses, likely acting as a spring loaded with potential energy. Then a fast-contracting trigger muscle releases the jaws and the stored energy, executing the strike.
