Water Boatman Sings With Its Genitals
Meet the singing penis.
An insect called the water boatman, not much bigger than a sprinkle on a cupcake, makes a chirping sound by rubbing its penis against its belly, a musical innovation similar to the way male crickets chirp by rubbing their wings together.
Not only does it sing, it’s loud. The water boatman’s musical tackle peaked in experiments at 105 decibels, just a little louder than an outboard motor or a jet flyover at 1,000 feet, making its crotch concerto the loudest sound relative to body size of any animal.
