The reversal of claw asymmetry in snapping shrimp is thought to be unique in nature. [12] The snapping shrimp competes with much larger animals such as the sperm whale and beluga whale for the title of loudest animal in the sea. [citation needed] When in colonies, the snapping shrimp can interfere with sonar and underwater communication.
The bigclaw snapping shrimp produces a loud, staccato concussive noise with its snapping claw. The sound is produced when the claw snaps shut at great speed creating a high-speed water jet. This creates a small, short-lived cavitation bubble and it is the immediate collapse of this bubble that creates the sound. [3] A spark is formed at the ...
Pistol shrimp (also called snapping shrimp) produce a type of cavitation luminescence from a collapsing bubble caused by quickly snapping its claw. The animal snaps a specialized claw shut to create a cavitation bubble that generates acoustic pressures of up to 80 kPa at a distance of 4 cm from the claw.

Alpheus macrocheles is a marine species. [3] It can be found living underwater in fissures and hollows underneath rocks and boulders. [2] They generally favour larger boulders on the lower shoreline. [2]
Alpheus is a genus of snapping shrimp of the family Alpheidae.This genus contains in excess of 330 species, [1] making this the most species-rich genus of shrimp. [2] Like other snapping shrimp, the claws of Alpheus are asymmetrical, with one of the claws enlarged for making a popping noise. [3]
Alpheus randalli is a medium-sized snapping shrimp growing to about 3 centimetres (1.2 in) long. The rostrum of Alpheus randalli is half as long again as it is broad and the carapace is not laterally compressed. The chelipeds are asymmetric, one carrying a massive snapping claw. The background colour of this shrimp is white or transparent with ...
When a potential prey approaches this shrimp, it opens its large pincer wide and advances on the intruder, snapping the claw shut with a loud click. This sends out a jet of water like a water pistol and "knocks out" its prey; the click is caused by the bursting of the cavitation bubble that forms as the claw closes. The stunned prey is carried ...
