Snapping shrimps preys by clasping its large claw to send out high speed water jet, triggering a stunning sound together with very high temperature and light emission. In this paper, systematic analysis of the striking process is made based on the principles of physical chemistry such as energy conservation and adiabatic process. Through calculation of the kinetic energy induced by the water jet, the expansion work and heat relating to the formation of the largest vapor bubble during the strike, the total energy sent by the interesting marine creature are determined. By calculating the residual vapor volume after collapsing of the bubble, the highest temperature that the residual vapor could attain, the optical energy and the acoustic energy, the dissipation ways of the energy sent by the shrimp are revealed. It is found that the whole strike process can be satisfactorily explained.
