A look back at the loudest penis

As 2011 fades into history, let’s take a look back at Dr. Windmill [pictured here] and the loudest penis of the year. That loudness rating pertains to the publicity received, as much as to the decibels produced. Here’s a BBC Report by Ella Davies, on June 30:

‘Singing penis’ sets noise record for water insect

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.

In a study published in the journal PLoS One, the scientists discovered that the small animals make a mighty sound….

The study is:
