While a hippopotamus’ Heart is only about 2% of its weight, this is because the hippo’s Heart has to pump blood through much thicker tissue. A hippo’s Heart also beats about twice as fast as a human’s and can pump up to 25 gallons of blood per minute! That’s more than any other land animal!

The giraffe’s Heart

Despite being so tall, the giraffe only has a heart that weighs less than 10 pounds.

That is significantly smaller than other animals, such as the hippopotamus and the elephant. For example, the hippopotamus has a heart that weighs around 25 pounds, while the elephant’s Heart weighs in at approximately 88 pounds!

This enormous discrepancy is because of how these animals use their hearts. Giraffes don’t need to exert themselves as much as other animals, so their hearts don’t need to be as significant. 

But, on the other hand, elephants and hippos have to work a lot harder to get around, and they need that bigger Heart to support them.
