Loudest animal: Micronecta scholtzi, freshwater insects aka 'singing penis'!

A tiny water boatman is the loudest animal on Earth relative to its body size, a study has revealed.

Scientists from France and Scotland recorded the aquatic animal "singing" at up to 99.2 decibels, the equivalent of listening to a loud orchestra play while sitting in the front row.

The insect makes the sound by rubbing its penis against its abdomen in a process known as "stridulation".

Researchers say the song is a courtship display performed to attract a mate.

Micronecta scholtzi are freshwater insects measuring just 2mm that are common across Europe.
