You never thought we'd ask about a farm bird's tongue, but here we are. What is unique about the tongue of a goose?

If you look in a goose's mouth you'll see what look like little fangs. Those are in fact the serrated edge of a goose's tongue, used to sieve water from each mouthful of underwater food so the food gets caught and the water runs out.
