The U.S. Navy Hid Its Submarines Behind This Tiny Shrimp During WWII. 🦐🌊 This is a pistol shrimp. It's smaller than your finger. Its claw snaps so fast it creates a shockwave that kills prey instantly. The sound hits 218 decibels — louder than a gunshot. During World War II, enemy sonar couldn't detect U.S. submarines hiding in pistol shrimp colonies. The ocean floor was so loud from the snapping, it drowned out the entire fleet. The Navy literally used nature as acoustic camouflage. 🔊 Sound
