Researchers have found that bats use “death metal growls” as a means of communication

Researchers at the University of Southern Denmark have found that bats use “death metal growls” to communicate. 

According to their studies, the species Daubenton’s bat (Myotis daubentonii) uses its larynx in order to make sounds, and, in doing so, they use the same vocal techniques as the likes of George ‘Corpsegrinder’ Fisher of Cannibal Corpse

On the published article “Bats expand their vocal range by recruiting different laryngeal structures for echolocation and social communication” by Jonas Håkansson, Cathrine Mikkelsen, Lasse Jakobsen and Coen Elemans, the authors state that:

“In humans, ventricular folds play a role in several low-frequency forms of singing, such as death metal grunting and Tuvan throat singing, where they can touch the vocal fold and increase the mass of the oscillating structures.

Furthermore, we show that bats extend their lower vocal range by recruiting their ventricular folds – as in death metal growls – that vibrate at distinctly lower frequencies of 1 to 5 kHz for producing agonistic social calls.”
