Biggest of the Biggest

On the list of huge things in the world, the whale’s heart is the most notable. At over 400 pounds, the whale’s heart is just a percent of its total body weight. An amazing fact about the mammal’s cardiovascular system is that its heartbeat can be detected from 2 miles away.

Besides being the largest heart on the planet, there is still some degree of facts about the blue whale’s heart. Its aorta is said to measure over nine inches, just like the size of a dinner plate. It also has the size of a small golf cart, and its heartbeat tends to slow down when diving to over 1,000 feet. Though as huge as it may seem, the blue whale’s heart is only 1% of its whole-body weight.
