But now it seems the mammals are also fans of his. Bats greet each other with death metal growls, scientists have discovered, and possess a vocal range which far surpasses that of most humans. While they emit ultrasonic chirps to echolocate flying insects in the dark, they also engage thick structures in the larynx called ventricular folds to communicate with each other at low frequencies. The production of sound from ventricular folds, which sit just above the vocal cords, is believed to be rare in the animal kingdom, with bats now gaining membership to an exclusive club populated almost entirely by death metal and Tuvan throat singers. “If you listen to a bat colony in the summer you can hear these calls very clearly,” said Prof Coen Elemans, who led the research at the University of Southern Denmark.
