The shrimp pistol

The pistol shrimp as its name suggests uses one of its pliers as a pistol for an attack tool. It has a clamp bigger than the other, which it closes at more than 100km / hour .. yes if !!! This will then create an air bubble which, upon imploding, will emit a sound at more than 200 decibels. It therefore knocks out its prey by noise.

here is a video found very explicit below.
