Schmitz, A. von der Heydt, and D. Lohse. [11] Similar values are reported by Ferguson and Cleary. The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kilopascals (12psi) at a distance of 4cm from the claw. [15], The snapping is used for hunting (hence the alternative name "pistol shrimp"), as well as for communication. This behavior is being studied.

[7], Pistol shrimp have the ability to reverse claws. By using computer modeling and 3-D printing and mapping evolutionary trees, researchers at the University of Alberta have discovered a possible evolutionary pathway that shows how snapping shrimp have evolved to "snap.". Like many crustaceans, they have one claw that is larger than the other and in most respects looks like typical shrimp. Then it extends its antennae outwards to determine if a prey is passing.

For example Pistol Shrimps can be found on coral rocky bottoms, as well as coral reefs, coral reef cavities, debris, and coral cracks. The flash is likely a byproduct of the insane pressure changes, temperature changes, and sonic waves emitted during the bubble implosion [3].
