In your article you refer to imploding “air bubbles” that are produced by shrimp. However, these cavities, which are formed by cavitation, are filled with water vapor, not air. As the shrimp claws move rapidly through the water, a low-pressure area is formed behind the claws. If the pressure is below the vapor pressure of water, water vapor will fill the area.
