The pistol shrimp (also known as the snapping shrimp) is a fascinating marine creature with one of the most powerful biological weapons in the animal kingdom — its claw.
This shrimp can snap its claw shut so rapidly that it generates a high-speed cavitation bubble.
When this bubble collapses, it produces a shockwave reaching speeds of up to 60 mph (about 97 km/h) and temperatures nearly as hot as the sun’s surface (~4,700°C or 8,500°F) — though for a microsecond and in a localized space.
This bubble bullet is strong enough to stun or even kill small prey, which the shrimp then captures and consumes.
The snap is also extremely loud, reaching 210 decibels, making the pistol shrimp one of the loudest animals in the ocean relative to its size.
The phenomenon is not just physical but also a form of communication and territorial display among pistol shrimp.
Researchers have studied this snap as an example of biological sonar and high-speed fluid dynamics.
