A blue whale’s heart is about 5 feet long, 4 feet wide, and 5 feet tall. It weighs about 400 pounds.
The 400-pound heart of a 40,000-pound animal is still pretty big, Even though the heart is only about 1% of the whale’s body weight, it’s still the biggest on the planet
The blue whale (Balaenoptera musculus) has the largest heart of any living creature. It can weigh over 1,500 lb (680 kg) and be as large as a small automobile.
The aorta is large enough for an adult to crawl through and it pumps approximately 15,000 pints of blood as compared to 8 pints in a human being.
These gigantic sea creatures are the largest animal to have ever lived. Their arteries are so huge that a human could crawl through them.
A blue whale’s heart weighs about 14 times as much as an elephant’s heart and about 640 times as much as a human heart.
Some source said that the heart of one blue whale was recorded at nearly 700 kg (about 1,500 pounds).
