Cavitation in a Pistol Shrimp
When pistol shrimps attack their prey with their claw it almost sounds like the shrimp is punching its victim sometimes. This is not the case however. The Pistol Shrimp uses the means of cavitation to stun its prey. Cavitation happens when something moves quick enough through the water to vaporise the water and create superheated bubbles that cause massive amounts of damage when they hit something. The shrimp snaps its claws together quickly and stuns its prey by snapping a cavitation bubble right near it with its claw (all in less than a second). Once the prey (or sometimes enemy) is stunned it can attack without risk of injury.
