You Can Hear A Blue Whale’s Heartbeat From More Than 2 Miles Away

There are two facts about a whale’s heart that will knock your socks off. The first one is that a whale’s heart weighs 400 pounds. That’s the same weight as a small piano! Did you know that a whale’s heart can be heard beating up to two miles underwater? Any fish within two miles of a whale knows they better get out of Dodge quickly unless they want to be eaten. It’s hard to imagine what the fish in the sea must think when they hear the sound of a whale’s heart in their ear. The first and only thought that comes into their mind must be how fast they can high tail it out of there.
