A snapping shrimp's claw can produce a tiny flash of light
When a snapping shrimp closes its specialized claw, it creates a fast-moving water jet and a collapsing bubble. The collapse produces a powerful pressure pulse and can generate a brief flash of light through sonoluminescence. The flash is too faint and short to see with the naked eye. A tiny crustacean can create an extreme physical event using only its claw.
