Snapping shrimp make flashing bubbles

Detlef Lohse1, Barbara Schmitz2 & Michel Versluis1

Snapping shrimp produce a loud crackling noise1, 2 that is intense enough to disturb underwater communication. This sound originates from the violent collapse of a large cavitation bubble generated under the tensile forces of a high-velocity water jet formed when the shrimp's snapper-claw snaps shut3 (Fig. 1). Here we show that a short, intense flash of light is emitted as the bubble collapses, indicating that extreme pressures and temperatures of at least 5,000 K (ref. 4) must exist inside the bubble at the point of collapse. We have dubbed this phenomenon 'shrimpoluminescence' — the first observation, to our knowledge, of this mode of light production in any animal — because of its apparent similarity to sonoluminescence5, 6, the light emission from a bubble periodically driven by ultrasound.
