How Snapping shrimps catch their prey?

Snapping shrimps are also known as pistol shrimps. They have a deadly weapon to catch their prey. According to the BBC, their enlarged claw can emit a shock wave that stuns the prey. This is how it works: [a] They shut their “super claw” in a rapid action. [b] A jet of water shoots out. [c] This action creates a bubble. [d] The bubble implodes. [e] A flash of light is emitted, which has been described as “shrimpoluminescence”. [f] This luminescence is indication of the extreme pressure and temperature reached inside the bubble at the point of collapse. [g] If you hear the sound of snapping from a shrimp, you can be sure it is from this bubble blast collapsing.
