The Pistol Shrimp’s Collapsing Bubble Can Reach Temperatures as Hot as the Sun’s Surface The tiny pistol shrimp—also known as the snapping shrimp—produces one of the most extreme physical phenomena found in nature. When it snaps its oversized claw shut, it doesn’t strike prey directly. Instead, it creates a high-speed jet of water that forms a cavitation bubble. When that bubble collapses, it briefly generates temperatures of several thousand degrees Celsius, comparable to the surface temperatur
