Just how big is a blue whale's heart? See for yourself...

Stashed in: Whales!, Best Videos, Heart, Interesting, Size matters.

To save this post, select a stash from drop-down menu or type in a new one:


The heart is approximately 5 feet (1.5 meters) long from the top of the aorta to the lowest chamber, weighs 400 pounds (181 kilograms) and can pump 58 gallons (220 liters) of blood through a blue whale's body with every beat. Miller points out that it's not as big as some scientists have suspected.

Miller shows in the video below how having the heart can help scientists learn lots of new things about this majestic endangered species and even debunk a lot of widely held beliefs about the blue whale.

For instance, she disproves the idea that the blue whale's aorta is big enough for a person to swim through or drive a car through. As you'll see in the video, you can't even fit a Volkswagen Beetle through it. Well, technically, you could if you took it apart and passed each piece through it, but you'd just be ruining a perfectly good car and blue whale heart.

58 gallons of blood?!

I recently got a T-shirt for having donated 2 gallons of blood! Took me a long time tho :)

Which means you fully comprehend how many gallons of blood 58 is.
