Scientists recently discovered bats, like Tuvan throat singers and death-metal vocalists, produce sound using ventricular folds instead of vocal cords. A Danish biologist found bats use these for low-frequency calls. With their ability to also make extremely high-pitched calls, bats possess an unparalleled vocal range. The Center for Biological Diversity argues this makes them more akin to grindcore vocalists, who utilize both very low and very high frequencies.

The Center for Biological Diversity, a 501c3 nonprofit, works to secure a future for all species through science, law, and creative media. Check out our video to hear biodiversity-loving grindcore artists and see brutally cute bats. Learn more at biologicaldiversity.org or email us at center@biologicaldiversity.org.
