Pistol shrimp

Alpheidae a.k.a the pistol shrimp is one of the loudest animals in the sea. The quick snaps it makes with its specialized claw creates a cavitation bubble moving at 60 miles per hour. When the bubble collapses it reaches temperatures of over 7,700°C and is 218 decibels loud, which is strong enough to kill small fish, and even create a tiny flash of light.
