The force created by the impact of the mantis shrimp's club is more than 1,000 times its own weight. It's so powerful that researchers studying it need to keep the animal in a special aquarium in the lab so it doesn't break the glass. Also, the acceleration of the club creates cavitation, meaning it shears the water, literally boiling it, forming cavitation bubbles that implode, yielding a secondary impact on the mantis shrimp's prey.
