7 Animals that Can Be Heard for Long Distances


Northern Elephant Seal Bull

Along the coastline of California live strange-looking elephant seals, with huge snouts and big, floppy bodies. When it's time to mate, the males, or "bulls," let out a call similar to an elephant's trumpet. This call, which can be heard for several miles, lets other males -- and all the females nearby -- know who's in control of the area.
