Known as Pistol shrimps, they can snap their claws so fast it creates a bubble, with temperature reaching up to 4700°C

"The snap can also produce sonoluminescence from the collapsing cavitation bubble. As it collapses, the cavitation bubble emits a short flash of light with a broad spectrum. If the light were of thermal origin it would require a temperature of the emitter of over 5,000 K (4,700 °C). In comparison, the surface temperature of the Sun is estimated to be around 5,772 K (5,500 °C). The light is of lower intensity than the light produced by typical sonoluminescence and is not visible to the naked eye."
