The Colossal Blue Whale and Its Intriguing Heartbeat

The blue whale, the largest animal ever known to have existed, boasts a heart that matches its colossal size.

This giant creature's heart measures about five feet long, four feet wide, and five feet tall, roughly the size of a small car, and weighs around 400 pounds.

But, even more interestingly, the blue whale's heartbeat is uniquely captivating.

A blue whale's heartbeat can be detected from two miles away and can beat up to 37 times per minute at its peak activity rates.

However, during a dive for feeding, the heartbeat slows drastically, and the time between two beats can be as long as 36.5 seconds.

This slower heart rate is thought to save oxygen, allowing these massive creatures to stay underwater for an impressive length of time, offering us an incredible snapshot of the fascinating biological adaptations of these marine giants..
