Trap-jaw ants of this genus have the second-fastest moving predatory appendages within the animal kingdom,[2] after the dracula ant (Mystrium camillae).[8] One study of Odontomachus bauri recorded peak speeds between 126 and 230 km/h (78 and 143 mph), with the jaws closing within just 130 microseconds on average. The peak force exerted was in the order of 300 times the body weight of the ant, and acceleration of 1,000,000 m/s² or 100,000 g. [
