Snapping shrimp produce a loud crackling noise 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 shut (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… Expand

Research on Claw Motion Characteristics and Cavitation Bubbles of Snapping Shrimp
TLDR
The equivalent model of snapper claw was constructed through CT scanning technology and a high-speed camera was used to capture the claw's motion characteristics, thereby simulating the production of cavitation bubbles by snapping shrimp. Expand
SNAPPING SHRIMP DOMINATED NATURAL SOUNDSCAPE IN SINGAPORE WATERS
Snapping shrimp dominate the high frequency soundscape in the warm shallow waters around Singapore. The noises produced by these small creatures are a result of the collapse of cavitation bubblesExpand
Acoustic sensing in snapping shrimp dominated environments
Snapping shrimp dominate the high frequency soundscape in shallow warm waters. The noises produced by these small creatures are a result of the collapse of cavitation bubbles they produce. During theExpand
Research on the Cavitation in the Snapping Shrimp: A Review
TLDR
The article summarizes the progress and results of the research, and proposes the bionic technology is the research direction of cavitation by snapping shrimps in the future, which is based on research of the biological structure of the snapping claw. Expand
Bioinspired mechanical device generates plasma in water via cavitation
TLDR
A bioinspired mechanical device that mimics the plasma generation technique of the snapping shrimp, manufactured using additive manufacturing based on micro–x-ray computed tomography of a snapping shrimp claw molt. Expand
Structure, mechanical properties and surface morphology of the snapping shrimp claw
The snapping shrimp preys by rapidly closing its snapping claw to generate a fast water jet, creating a shockwave that bombards the nearby prey and other shrimp. This behaviour has led toExpand
Unveiling the physical mechanism behind pistol shrimp cavitation
TLDR
Simulations show that during claw closure, a high velocity jet forms, inducing vortex roll-up around it, leading to the formation of a cavitation ring, which collapses and rebounds, producing high pressure pulses. Expand
Experimental study on interaction, shock wave emission and ice breaking of two collapsing bubbles
In this work ice breaking caused by a pair of interacting collapsing bubbles was studied by an experimental approach. The bubbles were generated by an underwater electric discharge simultaneously,Expand
Single bubble sonoluminescence
Single-bubble sonoluminescence occurs when an acoustically trapped and periodically driven gas bubble collapses so strongly that the energy focusing at collapse leads to light emission. DetailedExpand
Bubble puzzles: From fundamentals to applications
For centuries, bubbles have fascinated artists, engineers, and scientists alike. In spite of century-long research on them, new and often surprising bubble phenomena, features, and applications keepExpand

How snapping shrimp snap: through cavitating bubbles.
TLDR
Hydphone measurements in conjunction with time-controlled high-speed imaging of the claw closure demonstrate that the sound is emitted at the cavitation bubble collapse and not on claw closure, and a model for the bubble dynamics based on a Rayleigh-Plesset-type equation quantitatively accounts for the time dependence of the bubble radius and for the emitted sound.

Sonoluminescence temperatures during multi-bubble cavitation
Acoustic cavitation—the formation and implosive collapse of bubbles—occurs when a liquid is exposed to intense sound. Cavitation can produce white noise, sonochemical reactions, erosion of hardExpand
