shrimpoluminescence
 

A buddy sent me these links at work today. Has anyone read about this?

There was some research a few years ago on how the pistol shrimp generated
its "bang". It's not from each side of its claw slapping together as they
thought, but the implosion of a cavitation bubble. It closes its claw so
fast, the water jet creates a cavitation bubble that implodes creating a
200dB bang! A very short pulse of light is emitted due to the intense
heating and from the wavelength of this light, the temperature inside this
bubble was measured at 5000K, nearly the surface temperature of the sun!
The same effect is generated by exciting a liquid droplet at its natural
frequency with sound waves called sonoluminescence, so they refered to this
as shrimpoluminescence... pretty cool stuff.
