1. Boatman
Engineers and evolutionary biologists in Scotland and France recorded the boatman—which is roughly the size of a grain of rice—”singing” in a tank. The aquatic insect’s songs peaked at 105 decibels, roughly equivalent to the volume of a pounding jackhammer within arm’s reach. The chirps are loud enough that humans can hear the sounds while standing at the edge of a boatman’s pond. Fortunately for nature lovers, though, nearly all the sound is lost when the noises cross from water to air.
