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 ...
The stunned prey is carried to the shrimp's lair and consumed. If for some reason the snapping claw is lost, the other claw enlarges, taking on the shape and function of the snapping claw, although never attaining the size of the original. At the next moult, a new small claw develops on the damaged limb, but does not resume its original ...
The adult creatures use the technique to stun passing fish and foes with a simple click of a spring-loaded claw. Young snapping shrimps’ claws ‘accelerate in water like a bullet’ Skip to ...
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]
An example of specialization of these asymmetrical chelae can be seen in the Alpheus heterochaelis, the bigclaw snapping shrimp. The enlarged snapping claws of these shrimp are capable of snapping shut with such force to shoot a jet of water and create a loud popping noise, which they use to deter predators and other members of their species.

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 ...
Like other species within the genus Alpheus the claws of Alpheus macrocheles are asymmetrical, with one of the claws being larger than the other. [4] The larger claw is used for hunting small prey animals and self defence against predators and their own species.
