Abstract

The alpheids, pistol shrimps or snapping shrimps are a group of small decapod crustaceans characterized by their asymmetric claws. The larger claws are capable  of projecting  high-speed  water jets.  The pressure  generated  by the jet provides pistol shrimps with a tool to capture  their prey.  The speed  of    the jet is so great  that it induces  a cavitation bubble that collapses in less than a millisecond, generating        a tiny plasma ball with temperatures of more  than 4500ºC and producing  a very loud sound. These and  other characteristics (eusociality in some species, symbiosis with fish, regeneration ability) make these small shrimps fascinating beings.
