The Everglades National Park captured video of an alligator floating in a lake with its head and tail out of the water, and letting out an intimidating “deep roar that vibrates the water surface.”

The footage posted to the park’s Twitter feed was taken by Federico Acevedo of the Everglades National Park, and it is best viewed with the volume turned up.

The park described the video in other tweets:

“Did you know the American Alligator has no vocal cords but it can produce a wide range of sounds? Male alligators bellow loudly to warn off other males and attract mates. They do this by sucking air into their lungs and blowing it out in a deep roar.”
