The stunning Pistol shrimp

By in Animals

Pistol shrimps are fascinating crustaceans that have a very special way of hunting. By an extremely rapid closing of their oversized claw, the shrimp produce a loud snapping sound that stuns their prey. The noise made by the pistol shrimp is not caused by the claws hitting each other – as scientists used to believe – but by a jet of water created by the impact that shoots out at 100 km/h.

Scientists revealed that as the bubble collapses the bubble reaches temperatures of over 5,000 degress Kelvin, similar to the surface temperature of the sun, and even emits a short flash of light.

Although the snapping sound, which can be heard from great distances, is mainly used for hunting, pistol shrimps also use it for communication.
