Stunning shockwave

The pistol shrimp can snap its claws to communicate, but they can be used as a sonic weapon to prey on smaller shrimps. First the claw is cocked like a pistol and then fired. The effect is literally stunning. As the claw snaps shuts it fires a blast of bubbles. As the bubbles collapse they momentarily reach the temperature of the sun. This implosion, causes a shockwave that stuns the smaller shrimp and allows the pistol shrimp to collect its dinner.
