Did you know that hippos can actually hear through their jaws? When above the water they have their famous snort and grumble as a way of communicating, but once they’re under the water surface they use clicks that are more like orca language than anything else. These clicks are detected through an auditory nerve that’s in their jaw, rather than the ear.
