7 Animals that Can Be Heard for Long Distances

North American Bullfrog

The name comes from the loud, deep bellow that male frogs emit. This call can be heard up to a half mile away, making them seem bigger and more ferocious than they really are. To create this resonating sound used for his mating call, the male frog pumps air back and forth between his lungs and mouth and across his vocal cords.
