Researchers studying Mantis shrimp discovered that the shrimp’s hammer-like appendage can release a strike with a force over 1000 times its body weight. The appendage uses a system of latches, springs, and levers to release the blow. In addition to the initial strike, researchers discovered that a second round of energy is released via cavitation bubbles with an average force over 400 times its body weight. The methods used by the researchers confirmed that two loads of energy were released by testing their hypothesis via acoustic analysis, high speed videos, and motion sensors.
