17. Pistol shrimp snap their claws louder than Concorde – The diminutive pistol shrimp can snap one of its claws so hard that it tears water apart, creating a high-pressure bubble of gas called a cavitation bubble. As it collapses, the bubble creates a deafening pop as loud as 218 decibels, lasting for just one millisecond. Just before it bursts, the temperature inside the bubble soars to 4,700 degrees Celsius (8,500 degrees Fahrenheit), creating an intense flash of light (see diagram below). The shrimp uses this trick to stun prey.
