The blue whale is the largest animal on the planet, weighing up to 150 tons and measuring up to 90 feet long. Naturally, an animal this massive would have an equally massive heart. Roughly the size of a small car, the blue whale’s heart weighs about 1,300 pounds. To move blood through its massive body and huge arteries, it’s heart beats so powerfully, you can hear it from two miles away. You just might miss it, though, as its heart only beats eight to ten times per minute.
