EuroPeen Hall of Fame

The loudest peen on earth belongs to a tiny European species of aquatic freshwater insect. Micronecta scholtzi is a very small water boatman, just 2 mm long, but when it rubs its peen against its abdomen (a process known as stridulation, which serves to attract a mate), the chirping noise created can be up to 99.2 decibels. This is equivalent to sitting in the front row listening to a loud orchestra playing. Wow!
