The 2mm water boatman insect is the loudest creature on Earth in relation to its size, according to scientists in Scotland and France.
In addition, the feat is achieved through the frantic rubbing of its, ahem, penis.
The insect can reach a volume of up to 99.2 decibels by agitating its member against its abdomen, effectively singing for a mate in a bizarre courtship ritual. And the end result is the equivalent of listening to a loud orchestra while sitting in the front row. Admittedly, though, they tend to play instruments, rather than play with their instruments, so to speak.
