Given the power of the sound produced by the Pistol Shrimp, none other sound exceeds it in importance, since it is believed that it can even interfere with the measurement and recording of Bio Acoustic signals that submarines make in shallow waters. The physical phenomenon produced when the pincer closes, is known as cavitation, and it is a sound that reaches according to the experts, the two hundred and eighteen decibels. Upon closing the claw with impressive force, a plunger-like piece shoots the water out at speeds as fast as a car traveling down the highway.

When released, it snaps into the other part of the claw, emitting an enormously powerful wave of bubbles capable of stunning larger fish and breaking small glass jars.[5].
