The average human heart weights approximately 11 ounces and is about the size of a clenched fist. That begs the question, with all the massive animals out there, which ones have the biggest hearts, and just how big are they?
A Hyena has a heart that is relatively light compared to say, a giraffe, but, studies have shown that their hearts are nearly twice the weight of a lion. Furthermore, their hearts make up nearly 1% of their body weight.
A horses heart typically weights around 8 lbs, and is typically a rounder shape more so than “heart shaped.”
The Great White Shark is one of the most feared creatures on earth. The fact that they roam the dark depths of the ocean, well, that makes them even scarier. However, despite their menacing look and uncanny ability to hunt and kill, their hearts weigh only 10 lbs. But hey, that’s still more than 10x the weight of ours.
A camel heart beats at a rate of around 50 heats per minute, which works great for surviving in the desert heat they typically live in.
Weighing in anywhere from 3000-8000 lbs, the African White Rhino is the largest land mammal on earth after elephants.
A giraffe heart beats upwards of 170 pumps a minute. At nearly 35 lbs, that is one massive, quick-operating heart.
The Whale Shark is the largest fish in the ocean and has heart that weighs about as much as a medium sized dog. Researchers suggest that there are likely much larger Whale Sharks out there with larger hearts that they have yet to examine.
Elephants have hearts that tend to be more spherical in shape than a human heart. They can weigh anywhere from 21-29 Kilograms and make up approximately 0.5% of their total body weight.
