What they found was that the heart was about the size of a small golf cart. Also, the size of the aorta was not as big as once thought. It was big enough to squeeze your head through, but not big enough for a full-size human to crawl through. It might be time to update our information on the blue whale.
Blue whales might grow up to about 100 feet in length, so there might be blue whales that have larger hearts, but no one knows for sure right now. But the blue whale is still the largest animal that has ever lived! #bluewhales
